Also worth mention the main difference between AM and SSB (you mentioned it but I take it a little more in depth ;) ). When we modulate an AM-signal (let' say with a 1000Hz tone) at 27MHz, we will get 27MHz + and - 1000Hz; so we get 3 frequencies: 26.999MHz, 27.000MHz and 27.001MHz. The highest and lowest frequencies carries the modulation information, similar in both of them. The main carrier at 27.000MHz has no voice information at all. The output power is shared between these 3 frequencies, but we really need only one (lowest or highest) to get the information transmitted. If we remove the carrier (27.000MHz) and the upper side band (27.001MHz), we are left with 26.999MHz. That is our LSB signal. But this signal has all the RF power available, as nothing is lost to the two other frequencies. So in fact we have much more "effective" transmitter power available, than with AM. Technically much more expensive and complex than AM, but with much longer range pr. watt.
I was a side bander back in the mid 70's through the 80's. I see you are on channel 60 where I used to hang out. If I had an antenna I'd try to contact you on single side of upper channel 60. Cheers, mate, from eastern Tennessee.
I'm just now seeing this video. Another reason not to use FM is the capture effect. if 2 stations are talking at the same time on FM you will only hear the strongest station. On SSB sometimes you can hear more than one station at the same time.
You will get amazing transmit out of that radio. But your receive will leave something to be desired. I had one given to me. I actually used a scanner for receive and the radio for transmit because the scanner receives much quieter and much further than the RCI-2950. I am going to do the germanium Schottky diode detector modification to it. I ordered the transistors and germanium diodes from Amazon and they should get here soon. The radio mainly sits on a desk because I do not like the receive on it. But I found the components easily and this should change soon.
How did the new parts work for your receiver? I've had a first generation rci 2950 since they came out. I had my first base station on a starduster (the best antenna in my opinion) got into amatuer radio and moved, 8 years in the military and what do you know the rci 2950 came out of storage again. I look forward to using it on 10 meters. I always used an amplifier with a preamplifier to bring up the receiver and just back the rf gain down to get rid of the hash. I definitely could hear more than I could talk.
For the benefit of the readers who may not know. FM is about 10 kHz wide, ssb is about 2.3 kHz wide. The wider the signal needed, the more noise gets through. A qualifier, noise is not sound but anything that stops your signal getting through. 73 de Tony
Heyo just leaving a comment here, just a random hobbyist studying but I appreciate this video since there's so little information on this stuff somehow. Great explanation of some advantages of what originally seemed like a kind of confusing way to transmit signal lol
Hi Fred,Ive been saying for a while if manufactures fitted proper roofing filters in the RX chain,you'd get a lot less off that noise passing through! Even a basic 15khz 3 poles 1st stage filter would help bring the noise floor down,Ive tried this on the SS3900 and it works very well,it would increase cost but wll worth it.Another problem is most of these radios are far too sensitive when used in a base station set-up and with a gain antenna,for S-meter back the rf gain down till noise floor comfortable and can hear the station,most of the S-meters on CB are not very accurate or track well at 6dB per S-point.Great vid fred as usual!
@@CB-RADIO-UK £300 is pennies compared to the cost of even entry level HF transceivers. What does an ICOM 9700 cost now? £1400? Get one of those in the shack Fred and see how your noise is :)
In the late 1990s, a 12 watt SSB signal could talk regularly to the Canary Islands from northern Saskatchewan, Canada. Those were amazing times. Even with just 4 watts AM, it was easy to talk to Prince Edward Island from northern Saskatchewan. Many times, I could also talk to Puebla, Mexico. Today, very few use the citizen's band and the band conditions are horrible. Talking around town is about all that can be accomplished on most days on citizen's band. This is also true with 17, 15, 12, 10, 6, 4, 2, meters as well. Thought I am not an amateur radio operator. I remember an amateur radio operator talking on 2 meter USB with about 25 watts of power from Saskatchewan to the Southern United States of America. Today, I barely hear anybody at all in most bands. These are bleak times to be in any sort of a radio hobby. We are in a deep solar minimum where three solar minimums are coinciding together at once. This is not going away anytime soon.
Very good video. I have sat here all afternoon working from home with 27.5550 MHz (USB) sitting doing nothing. Made a few calls between emails. But nothing at all - I guess the time of day and weather (including solar weather which for HF reads poor on this band). Got more on bog standard FM earlier lol
It`s very difficult to create SSB transmitter In according to AM, PM, FM modulation. You must have a narrowband RF filter and a balancing modulator. There must be two IF in a wideband HF reciever. But there ia aery good alternative -a weaver method. You must have two syncronous DDS generators/
ACTUALLY WHEN YOU ARE IN FM MODE THE NOISE THAT YOU HEAR IS NOT THE INTERFERENCE of OTHER ELECTRONIC DEVICES BUT THE NATURAL FREQUENCY MODULATION CARRIER STAND BY ECHO WATING TO HAVE INFORMATION (SIGNAL) TO BE PUT ON BY THE MODULATION MIXER FROM A TRANSMITTING STATION. AND SINCE THE SINGLE SIDE BAND SIGNAL HAS NO CARRIER, THEREFORE ONE WILL HEAR NO ANNOYING NOISE WHEN IN SSB EVEN IN THE STAND BY MODE ephemetherson SQ5KIE
More narrow bandwith of transmitter and the receiver,more range.That is the point of using just 300Hz wide CW telegraphy and digital modes like FT8......SSB is narrowest way to translate human voice,just 3khz wide so it do have more range and more signal strenth at given power level than 10 khz wide FM or AM modulations.
SSB is SSOOO much better than AM. AM requires a really good set up. I have two AM CB radios. Which I think I am going to retire from for the most part. On roads trips they can be sort of fun.. And most SSB radios will do AM too. Making an AM CB kinda obsolete. Anyone, who wants to buy a CB hoping to make contacts, Make sure it can do SSB.
They do but once on the net they really will not want to jump up and down modes for a video. I have done fm and SSB compare contact videos on a few radios but only around 8 miles out.
@@CB-RADIO-UK I have compared all modes in the past. FM was the shortest range, but clearest due to bandwidth. AM was second shortest range it has a bandwidth just a bit narrower than FM. DSB had more range than AM. SSB had great range but clarity was rather poor. CW had phenomenal range but no voice can be sent over such a narrow signal.
Excellent video as usual Fred, simple and easily understood for those just starting. Hope you had a relaxing Easter break. We had a nice snowy one. It was like Christmas with Bunny rabbits and chocolate eggs. LoL.
You should see how far CW goes. I am really bad at it but it is amazing to hear a signal from Japan getting to Saskatchewan, Canada with only 10 watts. I am not an amateur radio operator. But I listen in a lot. CW is amazing when it comes to propagation. I even tapped out a slow Morse Code message on 38 USB and got a response once. With today's horrible atmospheric propagation, I was still able to receive from Washington, USA to Saskatchewan, Canada with just 12 watts. If only a voice mode could go that far in today's atmospheric propagation times regularly.
I could throw a stone and maybe hit a window across the road where our main High School is, and there is new Led street light outside my house, then there is a nursing home right besid my house split by a row of hedges and I have the same radio President Grant II Premium and your SSB static noise level is the same S Points as my FM giving me local chat and slightly further FM chat pick up no problem. If you did the same FM/SSB test on your FT450 and your Alinco would you still get the same result? The reason for asking and I have brought this up a few times with people that sometimes it can be the quality of the radio's fault. I have watched many of your videos Fred and felt your pain when you went through shutting the house power down etc, I have had three different radios that the needle didn't lift with noise and when local stations came in the nearly bent the needle incase some may say I merely lowered the RF gain and that was not the case. I even took one of these radios to my brother's home where he complained about the noise level was on the S8-9 solid and we put my Cobra I48 GTL DX, Cobra 25 LTD ST and my Major Excalibur 200 onto his antenna, all three radios on an empty channel on a normal night gave from no lift to less than S1. The worst radio for noise I ever had was a CRT 6900 and a couple of other Cybernet radios. My Yaesu FT450 MKIII (before the D model) is pretty good with around the same as my President Grant II Premium between 1 - 2 S points on normal days. Food for thought by trying other radios to see if you get different results.
Hi. Quick reply. On FM noise S level is about the same on all my radios. SSB the HF radios do a lot better with far less S point noise. I normally back off the RF gain on the 9900 and 6900 as they are very sensitive. Grant 2 is the worse for picking up QRM. The NB filter on both my Alinco HF radios and 450 is miles better than the others. See video here. th-cam.com/video/JZQ_VFr83Wk/w-d-xo.html
Like ssb for DX best and over 20 mile and Am local and DX. I do have grant 2 it not my cup of tea like older radios like present Jackson & grant Cober 148 gtl Dx still the best radios today.
Great video but the grant2 is known to be a crap magnet older radios are better filtered as when I had my grant2 it was 7-8 of noise but on my stalker 9 1.1of noise.
What about using SSB for listening to amateur radio? I was thinking about getting a tecsun pl-330 or pl-680 but I'm not sure if I'll pick up much at all I'm in the UK aswell so maybe quite limited compared to the u.s.a for example. What else might I pick up on an SSB shortwave radio these days I'm not sure it's worth spending the extra money on one and maybe sticking with a radiwow instead without SSB.
Hi. There are plenty of radio stations still using shortwave but not so many english speaking. You can pick up Hams on a Tecsun. What about a cheap SDR usb dongle for shortwave ? Google SDR
I've just been using web SDR and there's very few SW channels on there. They use a massive 20 ft aeriel antenna aswell. There's SSB and LSB there for radio ham's. It's a free website . SSB radios are expensive and there's quality issues with the Chinese brands. Also I think the DSP chips in the radio's affect SW channels.
The VHF frequencies carry radio noise a lot shorter distances than the HF frequencies. UHF frequencies are even quieter. HF allows the signal to bounce off the layers of the atmosphere and goes much further because of it. But VHF and UHF are much quiter. This is why it is important to have HF, VHF, and UHF frequencies at your disposal. There is a lot of RF noise produced by lots of equipment also.

I dont think you fully understand the subject you are talking about. For starters the noise you are hearing on fm is not QRM as your fm reciever is imune to this, anyway the noise will be the same on a quiet channel because this noise is internaly generated in the fm receiver itself. I think you are mixing this up with AM. If you have an electrical noise problem at your QTH you will be much better off using FM and you will pull in distant stations better with this for sure.
Me again .still not back on ☹️, funds not allowing . Hopefully after Christmas , unless santa has something in his sack for me . To my question for you all . Out of the new modern multi modes what one has the best receive ? . Back in the day I always used cybernet radios , sticking with a harrier cbx in the end . So which one's got the the best ear's over all the modes . Cheers
Hi. The Grant 2 (not prem) has the worst if used at home as it picks up to much QRM. Its fine if you get it out in the open. There is not much between the CRT6900N and the 9900. Both do a good job on SSB.
Really great point "Less RF interference on USB". Now I understand this benefit. Other videos no one mentioned that so thank you for the good lesson.

Null and void because you changed frequency! Stay on frequency and only change the mode!

Its a grey area and depends on local councils. You really need approval to erect an antenna on your house but no restriction on a free standing mount.
@@CB-RADIO-UK thank you always wondered
Is there nothing that will filter the qrm out
You can get filters. However iam not 100% they totally work.
One idea 💡 to try Fred, have you tried to use an antenna as far from the house as practically possible? It's just that some of my aerials are around 12m from the houses, I get very little Qrm. Compared to the long wire which is fed from the shack in the house 🏡, I get an average of S7. On the 'wire gain master' and smart tuned vertical I get much better signal to noise ratio quality (away from the houses). One final thing... Good screened coax is a bonus (especially double screened) for keeping away unwanted noise.

Well I completely wasted my money buying a CB and thunderpole, not a single person on at all.
Even on SSB. Its crashing in here ?

Good on you. So many people start on CB and then move along. You can always pop back to 11m when the skips in. Good luck.
WHAT THE HELL IS: STRAIGHT AWAY????????????????????
Sorry need a bit more to understand the question.
@@CB-RADIO-UK probably meant the QRM instantly going down when switching to ssb mode.
