How to Setup Your Receiver for Optimal Performance (IC-7300 & IC-7610)

- In this video Jarrad (who is a little sore today) demonstrates how to setup your transceiver's receiver for optimal performance.
Rob Sherwood points out that many Hams are not comfortable with using the RF Gain and Attenuator features, even though these features are essential to get the most out of modern SDR Radios and even Boat Anchors such as the Yaesu FT-101E.
We discuss how and when to use the Attenuator and RF Gain controls so that the band noise doesn't trigger the AGC function of the receiver, and how to ensure you're making the most of your receiver's dynamic range.
We also cover how these controls impact S meter readings, and why Ham's shouldn't worry about it.
Additionally, we demonstrate how useful the Auto Notch function can be, by emulating a LID tuning up on a DX Station's Frequency! :)
73 from Jarrad VK3BL and the Rate My Radio Team
We are not using the internal Icom tuner, or an external Icom AH-4. Please refrain from posting comments suggesting we do not know how to tune our own station, as they will just be deleted from now on as this has been covered many times before. Thanks, Jarrad.
Very good Jarrad, I use my RF gain control on every radio I have, when needed. In the old days that was our noise reduction, and really still outshines the dsp version we have now. Its ability to increase dynamic range is the best reason to use it. Plus the fact that most of todays radios have way too much gain to start with. I do not have an Icom IC7300 or IC7610, but the use of rf gain is the best thing to do for all radios which have the function. Thanks again for your videos which will help a great many new hams. Lastly it sounds like you have had people harrass you on how you tune up the antenna, to me it was obvious how you were tuing and I have and do it that way as well, a carrier any way you can easily get it to use for an external tuner. And you did right making it clear that the know it alls can keep their tongues, 73 my friend
Great video. I have been a ham since 1975 and have never had this explained so well. I followed along with your video while trying these adjustments on my 7300. Thank you Jarrad. Hope you are feeling better. 73 Vern W8UTS.
I will be receiving a ic 7300 Jan 3 so you made me a much better operator. My last contact was 1982 with a Drake c line. Back in the saddle again. A lot of new stuff to learn. Thank You
Great advice, thank you. Most people will not turn down the receiver sensitivity when they can hear anything, even though that is exactly what may be needed.
Just purchased a 7300, and this is very helpful, vs attempting to read a book, I prefer those who have used it and can focus on the important aspects.
This is very helpful for this new 7300 owner. Lots it can do. Thanks for sharing.
Great video, thank you very much! Down from surgery so I'm learning all about IC-7300, very well done.
Thanks for the information, I had a hard time with noise yesterday and look forward to applying your recommendations this afternoon, 73
Brilliant explanation, everyone should be taught this.
Thanks for another great video 73 De 2E0WET
Thanks for the kind words Alan! I wasn't my best with this one; I'm sore from a big job yesterday and I feel a little zonked out due to the pain killers. I'm glad it made sense to at least someone :). 73, Jarrad VK3BL
Great video. I love my Icom 7300, great radio for the money!
An amazing radio all round - perfect implementation of an SDR in a box from the word go! Can't say anything bad about the IC-7300 and I'm wondering whether we'll end up with another just to match the upcoming IC-9700! 73, Jarrad VK3BL
Hi Jarrad,
Works on my FT450. Thanks for jogging my memory. 73 WB3BJU
Great Video. I learned some great stuff. Thank you. I wish when LID's transmit, it would give their location. lol.
Very informative, and well described. Thank you for shedding some light on this. I understand the theory of the settings, however you have fine-tuned the info so-to-speak.
I have one of these, but I also have a five 90 ken wood and I like it a lot better. I do not have anything newer than this. I do have a seven o 6 and I love that radio, but it is a boat anchor.
Well said Jarrad, thanks! Let me make an additional recommendation -- I always adjust the IC-7300 RF Gain down to an S1 noise level on most of the lower bands. It dramatically improves the dynamic range of the AGC as you explained. In conjunction, I also adjust the REF scope setting on the second layer of soft keys. I found that if I DECREASE the RF Gain down a few S-units to the noise floor, I INCREASE the scope REF setting +3 to +9db so that the scope gives me a more sensitive visual reading of signals across the band, too (no RF impact on signals, just scope sensitivity). Doing both of these together makes for an amazing user experience. Try it :) 73s Greg, KJ6ER Silicon Valley
I wished that I had a AGC control setting on my cell phone, just so many adjustment's needed on a HF radio to hear/talk to someone, its just a toy to play with for Hams operators, me being one of them..
Thanks for the brief explanations. 73
well done Jarrad, very good..
my boat anchor 101 E always drifted. yes ai had to have it. if I could have ever stopped if from drifting. I would have enjoyed that radio.
Very useful.
I learned a lot thank you.
That all made perfect sence to me BRILLIANT great video VK6NJP :-) waiting for my IC-7300 to be delivered this week :-)
Thanks James :) You will thoroughly enjoy the radio when it enjoys this week! 73, Jarrad VK3BL :)
Jarrad, you mentioned in this video that you'd make another one on how to set up other ICOM radios - did you make one for the 7100 (and I don't mean the short review that you've already put up)? It seems the 7300 is set up differently than the 7100, as it's an SDR. Thanks.
Great video!!! I love all your videos!!! Robert K5TPC
Hi Jarrad, Are you using a full size G5RV and why is your noise floor on 80m so high? Also, did you actually say that accurate S readings are not important? are you a contester by any chance? This might sound rude, but how strong were the painkillers you were on om?
ICom 7300 : When you transmit there is a wave form scope next to the marker only when transmiting
How do you get that Anyone know .
Great information, well presented. Thanks. You said you're sore? Why? Thanks, Bobby de KM6PAX
How do you turn the radio on?
You claim if the rf gain is up it activates the AGC...please tell us how you determine when the AGC is activated???
Didnt expect a reply to this question
Brilliant! Thank you ... I shared with our Club. WU6X
And kudos to you for sharing, Dennis! I learned new stuff!
I’m glad we could be of service :). 73, Jarrad VK3BL & the RMR Team
If using a 7610 and doing a comparison of two antennas (Main and Sub receiver) , would you have the RFG set in the center position for both antenna 1 and 2 or would you adjust RFG so that band noise levels indicated are at the same level , different gain positions ?
Good question, I would normally adjust so both tickle S1, and then listen for Signal to Noise ratio advantages. 73, Jarrad VK3BL :)
Thanks, that is what I have been doing after watching your video on this topic.
Hi there can you tell me the normal place to set the Mic gain and compressor lever using a Heil PR781 Mic, mine is 60% on Mic gain and number 2 on compressor...with comp off the mic gain alone doesn't seem to activate the ALC very much till you get to about 60% from Fred in Uk.
They're great settings to use. The PR-781 needs a lot of gain so anywhere from 60-85% depending on your voice should be fine. Remember, any movement of the ALC - even approaching the recommended middle = distortion, so its best to keep it in the first quarter unless you're going for that rare one or can't be heard. 73, Jarrad VK3BL
I can do the same with my IC-718. Lowering the RF gain can be done on any radio. As
far as QRM and QRN the 7300 is no better than a 718. Both are noisy. To get serious
noise reduction you will have to spend more coin. Sorry to burst anyone's bubble but
7300 isn't much for filtering and noise reduction.
Good vid but a PITA to watch with all the YT ads inserted.
Thanks. Good review, and helpful as you always are.
It's interesting that some guys think they "must" give another operator a great reading but then they next tell them they didn't understand them and proceed to move on to another station, all the while giving the same inaccurate reports to everyone else. It's better to give someone a true more realistic reading. You won't sound like a fool and it will be more helpful to the other operator.
Seriously! If i sound awful I want to know! 🤣😂🤷🏼♂️.

I wish one of you guys would make a good instructional video that's helpful to tune a tube amp. I FIND NONE HELPFUL THUS FAR
Great video, thanks for sharing. M6VWM.
Does anyone get this annoying OVF flickering all the time, nothing in the manual about it Fred g4vvq.
Dear Fred, the best way of avoiding the 'OVF Flicker' is to not use pre-amps below 20M, lower the RF Gain on 40M, and use the attenuator on 80M and below. 73, Jarrad VK3BL
Hi Jarrad, ok thanks, yes i have turned it off now, dont need it on 20 by the look of it or below, i have also set the RF gain on Auto, there are 3 settings i had it on manual and turned right up, some people also put the Auto turner on and that seems to cure it...all a bit weird....just bought the radio, i really like it.....i have also got an ameritron 811H and trying to work out how to connect them together hi...from Fred in England.
Why do some stations use 1kw output? Its illegal! So stop it.
50.1xxxx as on the video is NOT 50 meters!
Nope, that would be 6 meters. Luckily, our audience is smart enough to pick up my mistake. 73, Jarrad
80 meters can be noisy but I would quit the hobby if I had S7-S8 noise. Wow.
Since starting this channel I’ve achieved DXCC on 80M it was a hard slog for sure! 73, Jarrad VK3BL
@@RateMyRadio You are very tenacious. Congratulations! de W3PAL.
Great video. I am running a G5RV and using the ATT has been helpful. Thanks for the good tips! 73
You're most welcome :) A G5RV is quite a bit of wire on bands above 80M, so it certainly doesn't hurt to add a little attenuation :)
73, Jarrad VK3BL
Great explanation on getting the best signal out of your rig with the minimal amount of noise! You were spot on about how irrelevant that S-Meter reading is in regards to someone's signal.
During contests, everyone gives out 59's even if they have to ask for their call sign 3 or 4 times because they can barely hear them, so what does it matter. Great job mate..73's
Thank you for this very helpful video Jarrad. I've had my IC7300 a week and had contacts accident rather than design. Your tutorial has helped me understand the principles of set-up and I feel better understanding about tuning and using the RF gain. I'm looking forward to being on the air tonight! Please do more videos. You speak clearly and to the point. An excellent presentation. thanks again.. Robert ZL2JED
Dear Robert,
Thanks for the kind words :) We're hoping to get a few more videos using the IC-7300 out soon as its a nice simple radio and good to use in demonstrations.
That said, with the IC-7610 in the shack sooner or later we'll need to move it on, so if you have any specific requests get them in quick - my email is on QRZ.com but don't be offended if it takes a while to reply, especially if you send a long email as I'm a little time poor at the moment but definitely read them and file them away for later reply :)
73, Jarrad VK3BL & the RMR Team :)
Would you suggest this Receiver for a new HAM Operator?
Jarrad, your IC-7300 video are going to be helpful to me real quick! My 7300 has been sitting on my desk long enough! I need to get it set up!. Trying to figure out antenna system to use and how I'm going to ground the Radio. Im in a Condo (top level thank God!) with a out side porch, what I have to work with to set up some kind of antenna.
Thank You So Much for this video!!!! As a newer HAM and a 7300 owner this will really improve my 7300 & HF Experience! Thanks Again and 73’s
You’re most welcome 73 :)
Great tutorial, helps a lot. I just got my General yesterday, have this radio new, not powered on yet also have the IC-7100. everything is kind of in Chinese to me still even though I studied for the upgrade, there are many concepts that I still do not visualize how they match or how they work; like if I power on the radio, I do not know what to do first but I guess that is why we get ourselves into this mess, I mean, hobby, lol. Little by little I will learn the ropes. 73 from Rody, KI7CSI
Dear Rody, I will be making a video on how to setup SUPERHET receivers such as the IC-7100, IC-7200, Kenwood TS-590SG in the coming weeks so it may be helpful as well. Basically the same concept, except the S Meter reads differently when RF Gain is adjusted. 73, Jarrad VK3BL :)
Too bad that Icom didn't provide an AGC Threshold Control (as an option to RF Gain), like many SDR receivers provide. AGCT is much more effective at providing the control you talk about. My 7300 was never as quiet (background noise) as my superhet rigs. It is a great rig & deserves (as do the operators) AGCT. -73
Thanks Jarred that was extremely helpful! What is your take on using Noise Reduction? (Thanks to your video I discovered that my IC7300 preamp was on. There's no indicator on the regular screen, and it memorizes this setting by band. I guess it pays to check all settings BY BAND once in a while to avoid such surprises.)
This is exactly what Ten Tec say when using their radio,s, give it plenty of volume and use the RF gain pretty much as a volume control. Glad youve made a video about this, it should help people have a more pleasurable experience when listening.
Hi Jarrad. I've had my IC-7300 for about a month now. This video inspired me to finally pull the trigger on one.
Now that I've gotten familiar with it a little- I want to share what I've noticed and see what your thoughts are. This is mainly about the RFG.
It seems like the RFG is way different from the traditional superhet radios. There's no surprise there since it is a direct sampling SDR. One of the main differences is that the S meter does go up as you turn down the RFG like it does on a classic rig. Instead, it goes down. Also - and this is the most important observation - the base level of noise doesn't go down at all until the S meter drops below 0. It may initially drop as you lower it a bit, but then the AGC catches up with what you did and the volume level of background noise goes back to what it was. In other words- the noise at S5 sounds the same if it's taken down to S1 with RFG. It seems like the direct sampling completely takes over, and the only way to get that noise down is to lower it below S0.
Does this line up with your own experience?
Yes it does completely - well observed. You are also correct that 0 is what you should aim for to avoid ALC triggering - this even includes most SuperHets for my knowledge. I hope you are loving your purchase, 73, Jarrad VK3BL :)
First off, fantastic video! Any ham that is active on HF should watch this to get the most out of their receiver. The tips and advice here are applicable to any receiver regardless of internal architecture. Thanks for taking the time to explain these settings in such a simple way.
Hi Jarrad,
I enjoyed your video, everyone who is thinking of using or buying a 7300 or 7610 should watch this.
Unfortunately some operators run these rigs receive flat out and then complain about OVF and overload and distortion when they don't know how to use the radio!
Classic example when a guy compared his FT 2000 to the 7300. He was running the 7300 with full RF Gain and pre Amp 1 on 40!
I pointed out to him on his comments he didn't know how to use the 7300, then he got miffed about it and said the 7300 was at FAULT. Eff me....!
I also have the 7300 and love it....I may get the 7610 later this year , maybe haven't decided yet...
I will look for you on 40 and give you a call if I hear you on and say hello. Conditions are tricky for me from this QTH though on 40. I live in Echuca northern VK3.
All the best and keep up the good work!
Les, VK3TEX, Echuca, Vic.
Dear Les, please do give me a call, and you are spot on - so many of the 'OVF' worry warts have their receivers setup incorrectly.
I can't imagine what kind of antenna would need a pre-amp on 40M, but some people believe that a pre-amp 'pulls in' the DX no matter what.
In my opinion the less active devices before the ADC the better... this is the true SDR dream.
The IC-7610 is very nice when running two antennas, but aside from that the IC-7300 is more than enough radio for almost anyone.
73, Jarrad VK3BL
Not only those SDR transceivers ! ;-)
Thank you so much for this. I have been finding a lot of noise on 20 meters this will help. I run the 7300 also. 73s
Jarrad, thank you for your fine video. I tried your procedure and the noise level did go down. But so did the information on my Spectrum Scope. All is blank. I had to change the REF to level 8 to see anything with your way of lowering the RF/Noise. Yet when I see your video, the Spectrum Scope is showing all manner of signals. Did you raise your REF to have it do so? Regards, 73 from N2LRB.
It depends on the band; the lower bands will tend to have more noise, but yes there is no problem of adjusting your REF for the scope. 73, Jarrad VK3BL :)
As a new Ham and 7300 owner, these videos are priceless. I look forward to more.
I just got my tech and general ticket New ham KC1KNT I also just got the IC 7300 and am trying to learn how to use it. I noticed that when you change bands you say " let me tune this up" and yopu switch to RTTY and hold the transmit hard key on the radio front. What does that do please Great video it has been quite helpful
5 years old and still super helpful for us noobs, thank you.
IC7300 receiver overloads and de senses horribly on 160 meter if receiving strong AM Broadcast signals near by. Now had and using is a high pass band filter inline on coax, all is good with the 7300 again! 40db worked well then picked up another unit giving a total of 80db which was better yet. In my collection of older analog radios the 160 meter band was never overload by these same broadcast stations just some birdies showed up on some upper bands. Guess there is something to be said about the approach using filters at the front end of the radio for the band design.
The same logic should also apply to your microphone, but it's obviously apparent that you've over processed the audio on this video. That said, I did appreciate the video and found it very helpful.
RF gain cuts the grass. It lowers the noise from the bottom up unlike a volume knob lowering all the noise evenly. Cutting the grass doesn't effect anything above the grass.
Generally I turn down the RF gain until the meter reads close to the noise floor, if it gets too quiet add volume.
Love your video, I noticed my reports were not 'Accurate' with the REF Gain turned down so once I get a good signal and RF where I like it, I set it to 12 o'clock to get the report and then put it back to optimal
I know this is off target but I've been racking my brain to find a way to run a external touch screen monitor with the ic-7610.I know it will drive a external monitor . look at it this way when you touch the screen it puts out a signal so if that signal is converted to the proper format it could be connected to the usb port .I wish I new some one from icom to look into this. I have been told by 2 people one says icom is working on this the other said it will never happen. And one more said it cant be done because either there is now way to access a driver or the driver isn't there. Let me know what u think. 73 DE KD6ERP
Check my other reply Rob; in short without firmware updates from Icom whilst technically possible it wouldn’t be very useful. 73, Jarrad VK3BL :)
Great video thank you. What do you think of the 7300's internal antenna tuner?
I think the internal tuner is fantastic; I love the fact it has an emergency mode that runs 50w but lets you match up to a 10:1 SWR which is far beyond the limit of what a good antenna would ever present. 73, Jarrad VK3BL :)
Good info. I use the RF gain as the volume control on my K2. I'm not worried about the S-meter - the RST code I think was developed before meters were common. No-one needs to be stronger than S8 anyway! Best wishes from Jon, G4LJW.
This is the best way to operate for sure. Some radios like the Kenwood TS-590SG will 'adjust' the S Meter to show you a compensated level which is kind of nice but takes a little to get used to; I wonder if the K2 does this?. 73, Jarrad VK3BL
I am going to order my 7300 soon! Thank you for the information! I will watch this again after I get it! Videos like this will make it easier to get it up and working easier!
Hi
What is suggested for audio output settings for AM?
Thanks

Self train and have a bit of fun... Spot F'n on Old Man
That's it! No other reason to be in a hobby unless you have fun, and what a great one it is when learning is involved too :)
Excellent video. Well presented. 11/10! Too many youtubers either have annoying voices, tiresome accents or try too hard to be funny!
Thank you for sharing. May I ask a question, would 7300 will be sufficient to be used in DX and local HF use? As with reception quality when do we need to choose the use of IC-7610? (Disregarding the dual receiver function in 7610).
Absolutely
When the RF gain is wide open, the band noise is Sn. If the noise level is reduced by the RF gain to S1, for example.
If a station signal is S7, so the actual S number is, 7+n-1.
Please correct me, if I am wrong.
Anyway, giving 59+ is more than enough, unless the station want to have accurate reading, for the example, comparing antennas. I agreed, signal strength is not as crucial, than reability. I prefer 53 signal than 29+.. :)
thank you for the excellent explaination.
de, 9W2GNU, 73.
Dear Mohammad, in theory that should be the case. That said, Rob Sherwood measured the IC-7300 S-Meter as follows: S1-S4 2.8dB / Unit, S5-S9 3.3dB / Unit, so it isn't linear unfortunately. Another reason not to worry so much about signal reports; the only thing manufacturers agree on is that S9 = 50 uVolts. Agreed, 53 is better than 29+ :)
Rate My Radio
I like to point out A very small mistake at minute 15:19
It should be 50 MHz,or 6 meters, not 50 meters.
Again, I agreed with you, S-meter just a signal strength indicator, not a an accurate for scientific research. Yaesu and KEnwood rigs' S-metering also differs. At least we know the signal is weak or strong.
Thank you.
Signal to noise ratio ! The Ref setting would be good to cover here too.
The REF setting is hard to cover, as its more a personal preference thing than anything; it really depends how you want your scope to look... whether you're a CWer etc.
Rate My Radio Well, for me when keeping the RF gain down it reduces the signal graph in the scope, the ref function increases the sensitivity or gain on the graph, thus giving you a level instead of nothing on the scope. I believe it goes hand in hand with what you’re teaching here. As you said the s-meter is reduced, but the ref function gives you that back in the form of the signal graph.
Dear Mark,
Indeed - you have a point they are related. We're trying to figure out the best way to use the REF function, and are currently experimenting with some alternatives. We will do a video covering the REF function and how to make the most of it; depending on how you use the radio, it can either be a frustrating 'feature' needing constant adjustment, or something you can set and forget.
73, Jarrad VK3BL & The Rate My Radio Team :)
Yes very good discussion on RF gain. I use that very method for years on my FT-101E and still do. Not worried about S-meter readings. This is the way ran our radios years ago to get rid of the noise. Thank you for the great video and now our secret is out.
Dear Lyle,
It certainly works magic with the FT-101E, I can attest to that. A well setup 101E produces some of the most pleasing SSB audio you will ever hear!
73, Jarrad VK3BL
Our golden standard antenna is the theoretical dipole or isotropic. It's why we reference antenna gain in dbi.
That's the only mistake you made hi hi.
de, kd5eax, 73
Thanks for the correction :). 73, Jarrad VK3BL
Why is the squelch combined? Does it have to be technically?

Excellent explanations about IC 7300 73 KC9QVE Tony Gas City,Indiana
Best is use whatsup and all problems are removed from em self.
Hi im a new m6 with a 7300 you say your tuning your radio why isn't the tuner button light on it looks to me your pressing your transmit button when I tune my antenna I hit tune button or am I doing it wrong Thanks
Dear John, you're almost certainly doing it correctly for your setup. What isn't shown in this video is my external Palstar HF-Auto tuner, that can tune with inputs up to 100W. 73, Jarrad VK3BL :)
Jarred I am looking at both the 7300 and the 7610. I have seen your video 5 ways the 7300 is better. However, I wonder what your opinion is why an operator should buy a 7610 over a 7300. Enjoy your videos and wish you the best. 73 Chris KC5AD
Dear Chris, the 7610 IS a superior radio overall, but I did want to draw attention to the absolute value of the IC-7300. In my opinion, you should only buy an IC-7610 if you have 2 or more antennas (comparing them in real time is one of the great joys of the 7610), and the rest of your station is up to scratch e.g. you have a linear amplifier if you want one, a good tuner if needed, and a beam antenna if possible. If funds are no object, of course go for the IC-7610. The price drops have made it a much better value proposition. Thanks for the question and kind remarks, 73 Jarrad VK3BL
New ham question...If you reduce the RF gain until it is as you say tickling s1, doesn't that reduce the ability of the radio to hear weak stations that it would have heard had rf gain been set to the 12 oclock position?
Simple test: Disconnect the antenna. If the noise out of the speaker drops, then the answer is no. :). Good question, 73, Jarrad VK3BL :)
Thank you for the good information it was a great help.
When i do an swr check I’m at 1.5 with 1% or watt. When i increase the power to 5% or 50-60-80% or watts. My swr goes over 3.0. Any ideas? Thanks guys.
I have to admit I thought you were full of it but I checked it out and you were right by lowering the rf gain it lowered the static more than the signal present … how ever when u went to 10 m it showed several spikes with no signal present . I found that confusing 73 DE KD6ERP
It would be due to the fact I don’t have an antenna up presently for 10M and didn’t tune on that frequency; the spikes would be local noise sources. Glad it was helpful 73, Jarrad VK3BL
Jarred,
Thanks for this enlightening video and I really enjoyed your explanation on this topic.
I have both a 7300 and 7610. You have explained the rf gain process clearly.
Thanks again. We will be looking forward in future videos as well.

Thank you for the smart video! Learning how to best operate my radios has been a long process, but this video makes it clear how I should operate the RF gain. No longer will my RF gain be all the way to the right all the time. :D de w8tam
Dear Thomas, you're most welcome! Thanks for the kind words and dropping by with the comment. Hope to work you and all our other viewers one day! 73 de VK3BL Jarrad & the RMR Team :)
Question: When you change bands, you "Tune up" by switching to RTTY and pressing the TRANSMIT button. Why? What does this do?
We run an external Palstar HF-AUTO Antenna Tuner; in order to tune it needs a carrier between 10-30 watts (it is rated up to 100).
As we don't have a CW paddle on my desk, RTTY provides the easiest continuous carrier for my Palstar.
Whilst the Icom radios have a 'Tuner' button, it only works with either the internal tuner or an AH-4.
Does this answer the question?
73, Jarrad VK3BL & the Rate My Radio Team :)
Rate My Radio thanks! I was looking all over the manual for some feature I might have missed, but that explains it.
Rate My Radio
Is there any difference if I use AM or FM mode compared to RTTY mode, in term of TX power output. ?
Thank you.
The Icom TUNER button also activates the LDG IT-100 and Z-100Plus (both interface compatible with the Icom AH-3 & -4 tuners.
I'd like to be able to set mine up like that! I'd sure like to get my hands on the 7300 I bought!!! Just wanted to let you know that I just bought a 7300 at DX Engineering @ 3:00AM this morning for $899.xx, charged transaction to my VISA! Now at 10:00AM I get a call from DXE saying ICOM won't let them honor the sale! I said then let ICOM know that the 7300 was my second ICOM HF Base purchase from you (and them), previously having purchased a new 7200. They said sorry, but they can't fulfill the transaction!!! I said...well, you're not yet sorry enough! I'll rate the product higher if the marketing and sales folks can just get their heads on right and deliver it as purchased.I'll rate the product & companies involved higher if the marketing and sales folks can just get their heads on right and deliver it as purchased. 73's K4WWK
Would have been a good vidio but all the dam adverts spoil it
'If you think about it'...most quality transceivers give you the correct S meter report when you back off the RF gain.Also, Japanese equipment uses 3db/S point.No wonder the signal reports below and above S 9 are better than the original standard 6db/S point. Stealth inflation, especially if you are comparing power level changes or antenna gain/f/b ratios.
one thing: Maybe you could instruct a bit on when and how to use IP+ ??
Great video, thank you! One question follows: How are you determining that the AGC is coming into play? I see the AGC-M on the display and it seems to be unaffected by your gain changes. - Cheers - Jim (KK7CSC)
Can you do a video on adjusting the ALC on SSB along with adjusting compression? Specifically addressing the "scale" which isn't labeled. Where exactly is the 30-50% they speak up in the manual when there is no label. :) Thanks

Great video, Jarrad. I learnt a lot about my 7300. Unrelated, but I knew the previous holder of VK3BL licence very well. 73 from Mark VK3XVC
Any chance he will sell me the car plate?
@@RateMyRadio I don't have any contact with the family, his wife moved away many years ago to be closer with family I believe. Barrie used to collect car plates, I imagine his family wanted to keep that one.
@@CircuitofDoom thanks for the info. I’ve seen it once on a 4WD In dandenong a few years back now. The family should keep it if they have. 73!
Icom 7300. Can you get the spectrum scope to work outside the amateur bands. I know it works in AM broadcast but if you go above any ham band the water fall stops and says out of range.
what's up you hade 10 meters on the scope and it showed several spikes but no signals present
I don’t really have an antenna setup for 10M and wouldn’t have tuned the doublet so realistically the radio is just picking up strong local noise. 73, Jarrad VK3BL
