From NC, I really appreciate and enjoyed this video! Disabled Veteran and old school trucker, I have a mobile in my pickup truck. Gotta hang on somehow. Very informative, thanks for posting 🫡
i have this exxact meter model. i have the instructions, but it would be nice to find a video, that deal with this exact meter, on the tips and tricks to install it inline and set as it should. ..
It's worth noting that under the swr scale on that dosy meter there are numbers (4, 11, 25). That's the percentage of the fwd power that's being reflected back into the transmitter. At a 3:1 swr your antenna is only 75% efficient. Not only that, your finals have to dissipate the heat from your fwd power+ reflected power. So the finals in your cobra 148gtl that the golden screwdriver tech cranked up to 15 watts am, going into a 3:1 swr, have to dissipate the heat of 18 watts power. That's why the finals burn out.
Information please - with steel boom and aluminum elements, should I insulate them from each other are connect elements directly to steel boom.You have a good voice for videos.
Nothing wrong with a "Thru the glass" antenna if it is designed and grounded correctly. The mag mount is rather inefficient without proper grounding elsewhere. Wire to chassis for example.
hi i have a question, i recently bought a old midland 77-861 portable cb radio. and it works fine. but i noticed it has a small little meter on the top left that says BPS and has red and blue lines with a needle that moves when i talk or someone else talks. just wondering what BPS means. if you can please help i would appreciate it greatly.
I started with channel 1 at 1.4, and channel 40 at 2.3, so I shortened the antenna.. checked again and now I have channel 1 at 1.6 and channel 40 at 1.8 is that ok?> seems like the shorter I'm cutting the antenna the higher swr on channel 1 but its bringing the swr down on 40...
I agree with the video creator on this one. If I use the entire band I'll set it to be lower in the center however if I use one frequency more often I'll set it to that.
Thank You for the kind reply. I enjoy watching your're vids. Didn't see anything new for a while I hoped all was well with you and your family. Got you're eye on any new additions to the armory? Maybe you could tell us what you may be thinking about. Or let us know what ya been up to if you want to. Any way it was great to hear from ya. Stay safe my friend. PS I'll tell you my latest addition. Remington 1911 R1 Commander. It's the "plane jane" Government style. Black, short trigger, Spur hammer (that's the only Commander I've ever run across with a spur hammer) Three dot sights, but dovetailed so they could be swapped out.It's SWEET.
Jeremy is right. If you have any swing, that fluctuation will change the reading. When you calibrate the swr meter your basically telling the meter what the output power is. (The calibrate function disregards the reflected power) if you have a dead key of 4 watts and a swing to 8 watts with modulation. If you check the swr with background noise it's going to read higher. This is why you recalibrate the meter anytime there is a power change. The exception is If you have a cross needle swr meter. There is no need to calibrate those.
You're showing your swr, yes but speak into the mic if your swr moves up or down thats your swr. S in swr means standing so if it moves during speaking its no good it has to stand! Still. No offense but this is bs.
+pat McCormick Increase your output power if possible. If you keyed power is like 1 or 2 watts it may not be enough. Otherwise, if you cannot calibrate to set, just realize your SWR reading is going to read lower/better than it actually is. It will be somewhat relative.
I did not check the power, I have the same meter you have. I checked it with a small meter but the meter needle was bouncing around and was hard to set but I thought I had it calibrated with the needle going to the set mark. had a good swr on 20 and1. I just wanted to check it with the good meter being the dosi. thanks for getting back with me, Pat.
Dosy is worse than garbage but they make great targets at the gun range. If you’re standing wave ratio changes when you change the length of the coax you have issues with the antenna. I have 10 and 10 is outside my home and I can change the jumpers on my meters or the length of coacts going to those antennas and my standing wave ratio never changes on any of them and I have done it to prove a point to several people who insisted the same stupid comment that you made. Funny that you’re talking about using a piece of crap antenna’s when you have one of the biggest piece of crap wattmeters in-line.
You are both idiots. You need to learn more about antenna physics. I agree on you with the Dosy though. Coaxial length will change SWR readings because of its loss or attenuation. It will lower the SWR 'reading' at the antenna the longer you go. Also, if your antenna is not 50ohms like at the radio, the 50ohm coax behaves as an impedance transformer. Depending on its length based on phase angle, it will literally change the impedance, that is, what the radio sees.

Should we turn our Amos off to set the swr thank you sir I enjoy all your videos
Yes. Less power is safer for equipment if SWR is high.
102” wipe is what I’ve always had good luck with I know the antenna is long but I’ve Always had it flat with that antenna

You explain this in very simple terms for any idiot to understand, and thanks for the video help me refresh what I'm missed in the 80s thanks sir 😁
Great job! Very informative. I'm sportin a Cobra 2000 gtl and a Wilson 5000 just.as you mentioned in the video.
I need to measure swr on a 2meter rig, but all I have is a cb swr meter how far off will it be any idea it measure at 3 swr right now ?
I do not know. The meter should show it mghz range.
Excellent explanation of SWR! Thanks
Explaining the meter calibration, and why, would be good.
Information please - with steel boom and aluminum elements, should I insulate them from each other are connect elements directly to steel boom.You have a good voice for videos.
You need to be more specific with your question. Were you talking about a Yagi?
Are you sure that’s not backwards ? 2.5 on channel 1 and 1.5 on channel 40 , the antenna needs to be lengthened ? Right ?
And if you are running an amp you need to check swrs behind the radio and behind the amp.
are you familiar with the Galaxy DX949 CB Radio, would you be able to do a video on how to tune ?
+Flavio Santana No. I cannot tune. Take to reputable radio man.
Ok thanks

Tahoma LOL. NOT. I totally disagree on both points. Have a nice day

Excellent informative video; 5 stars.

To the best of my knowledge that meter combination of Battery Pack and Signal levels.
I started with channel 1 at 1.4, and channel 40 at 2.3, so I shortened the antenna..
checked again and now I have channel 1 at 1.6 and channel 40 at 1.8
is that ok?>
seems like the shorter I'm cutting the antenna the higher swr on channel 1 but its bringing the swr down on 40...
+WPGinterceptor What's your SWR on Channel 20?
1.7
semi truck.. on the mirrors
2
sure am.. gonna check out my ground
if it doesn't matter if you have on set why did they put on there
Good basic information for the new CB operator. 73's from the Rockies
+808intheminigrass 73's back to you from the Rockies. When did you leave the grass?
Thank you for this video. Very helpful for a newbie like me
What do you do when you hear truck noise going to the radio like when you raise the wind up here the noise or anything like that
Paul H Ford Put an RF choke on your power cord
Or direct wire to ypur battery
Stryker stryker stryker.. Nuff said. Lol
Always set your best SWR to the lowest frequency you use.
I agree with the video creator on this one. If I use the entire band I'll set it to be lower in the center however if I use one frequency more often I'll set it to that.
Good Explanation There Albee4ty5 Thanks !!!
Where ya been?
+joe batters I am still kickin Thnx

+joe batters Nice
Thanks, I'me like'in it.
hi, do I have to turn the power knob and Mic gain all the way to 0 before calibrate the antenna ???
Isaias Balbuena No. set them where you use them.
That's not right. You should turn the mic gain down if it is going pick up any noise.
Jeremy is right. If you have any swing, that fluctuation will change the reading.
When you calibrate the swr meter your basically telling the meter what the output power is. (The calibrate function disregards the reflected power) if you have a dead key of 4 watts and a swing to 8 watts with modulation. If you check the swr with background noise it's going to read higher.

Did this guy die?
You're showing your swr, yes but speak into the mic if your swr moves up or down thats your swr. S in swr means standing so if it moves during speaking its no good it has to stand! Still. No offense but this is bs.
I think you are getting confused about what standing waves really are. But yes, not many vids specify not to modulate when taking an SWR measurement.
@@arconeagain think there's much confusion around this subject, this video does nothing to help that
Wyoming let’s go hunting breaker lol be well
what if you can not calibrate, get the needle over to set.
+pat McCormick Increase your output power if possible. If you keyed power is like 1 or 2 watts it may not be enough. Otherwise, if you cannot calibrate to set, just realize your SWR reading is going to read lower/better than it actually is. It will be somewhat relative.
