I fully agree - even of FM I prefer the squelch off so that those signals right in the back of the box get a chance to be heard (somedays that is all that I get !). With such high levels of QRM on every band and frequency auto-squelch is a real pain . Back in the day with crowded airwaves it would have been a real boon but nowadays where I live it could lose me the one or two decent- but weak - contacts I get each week ! Good stuff as always Fred.
Jeah Fred, youre so da..n right!! As you can see in uncountable Videos, its all about getting as far as possible with HF and having great Moments with a new contact,even with weak signals. Its frustrating when hard trying guys are not heard because OMs have theire Sqelch at the right end. Your explaination on SSB is full correct. The noise floor on ssb is so low that you can hear stations even under the static. This is so much fun. If people only want strong signals an high quality Audio they should make a phone call. I hope my english is understandable and keeps my teacher rest in peace ;-) Very warm greetings from Germany my friend. Keep on doing Videos, for you and family 55 and 73 Sebastian
Hi Bud. Your English better than mine :-). I agree. I really find it hard when people comment on the 305 videos saying they were trying to get on the side and we missed them. With a squelch they prob stand no chance at all.
Good video Fred. I seldom use squelch at all. the only time I use it is when there is a terrible amount of noise and I use the squelch to quell the noise when I am conversing with another CB radio operator. I don't mind the radio noise really. I am used to it and you do hear distant stations in the squelch sometimes as well. I fully agree with your take on the squelch usage.
Squelch can be useful even on ssb ,, i use it if you have the rig on a particular frequency waiting for a sked or for propagation to open. You might think things are dead then it comes alive .so you can have silence, just waiting for things to happen, so in that sence it can be very useful. But as you say not much good when in mid contact .
Fame... That was my comment about breaking the squelch. I use the squelch because I'm mobile and I don't want to be concentrated on trying to hear that back of the box breaker on FM, I also don't want that constant distracting hiss whilst I'm driving. If I was homebase that would be different.
I always found a lot of stations on UK FM Could be a bit clicky, and deliberately squelch out surrounding breakers... Just my experience back in the day.. As for SSB I always leave the squelch open and use the Hi -cut and NB if needed.. Chers Fred another informative upload, for the newbies. 73s 153AT888
I never use squelch on the radio and never on Am or ssb and some time if you turn the RF gain back you will hear more great video all the best Fred untill next time
I never use squelch using ssb on the hf bands, there is too much noise and your right, you don't hear perfectly readable contacts, if you've "squelched" out the noise. Reducing rf gain helps reduce noise, turn the rf gain down and the audio volume up. Play with the latter two controls to get the best results.
Hi Fred, My name is Dale i:e Boomerang from Shrewsbury, Shropshire. May I ask, I was on the CB back in the 80 and coming back on to the CB by the looks of it there is not a lot going on in my town anymore, but I am still coming back on. I would just like to say I like your Vidos that you do.
Everyone need to use squelch at some point especially on FM if your listening all day I've never bothered with squelch when am on AM or SSB that's where I am mostly.
i agree with you fred when im on side band i never use squelch cause you never know if your missing a possible contact! 73's from 271 western south dakota usa
I never use squelch on AM but for FM, I use my old Pyatt "Superkrunch" box that I've had since the early '80's. It means I can comfortably hear people much further away than if I simply used the normal squelch which would have to be set at a pretty high level to remove the annoying white noise. If I DIDN'T use it, I would have a greater level of white noise from my XYL............
Perhaps someone who has been using modern CB radios recently can comment on this. I have always found squelch to be problematic with distant signals as Fred has mentioned. Most radios i've used once you engage the squelch, there has to be a significant increase in signal to break the squelch. Now i was just testing a 40 year old CB i just purchased and noticed something very interesting about the squelch. It is not a 'hard' squelch. You can put it right at the threshold and most noise will be cut out but you may hear a little coming through at a lower volume occasionally. I think this would mean that faint signals are much more likely to come through and not be blocked like a traditional squelch. This is not the way the squelch works on any recent radio i've used but i think it is a fantastic design for AM CB band. Perhaps this is the way squelch has been designed on CB radios and I just forgot since I hadn't used one in 35 years or so. Can someone comment on this.
The problem with the squelch on a lot of cb radios its based on RSSI signal strength level.Cb radios on FM often do not use Noise Squelch which is a far better system than using carrier signal being less susceptible to opening on noise ,depending on the manufacture design ,but in recent times FM noise squelch has become more popular in some radios. AGC attack\delay can also affect the squelch system especially multi-modes CB where sometimes the design is compromised and there the squelch action can in some cases be a bit iffy on "opening up"quickly on a signal,and often too fast "closing"(hysteresis) with multi-modes Am needs to be fast open,will some delay after signal to allow flutter of signals SSB needs fast opening but long delay before closing to allow voice "pauses" not shutting the squelch closed to quickly (some sets allow you to alter this feature,some you may have to modify hardware wise to get it right ) FM ASQ(not all uses generally noise squelch SS6900 does) the SS6900 in pc mode software can be adjusted in the "options screen" FM SQ Close set 150 mSecs (default) Am SQ Close set 150 mSecs (default) SSB\Cw SQ Close set 300 mSecs (changed) I dont think on the SS6900 menu can be accessed via radio,using the pc software maybe only way Fred,just make sure you READ radio contents,then Save DATA file safe,before modifying hopefully that will fix SSB squelch issues on SS-6900 ( tested this on a older V3.1 hardware SS-6900 using V1 PC software , but its also supported on V6 hardware\software PC software) PC software here V6 SS-6900 cdn.shopify.com/s/files/1/0223/4803/8208/files/SS_6900Setup_6.00.exe?537 ull need a pc programming cable CRE-8900 support this on pc software V3.1.0 SS9900-v4 -NO (have not looked further) Lincoln 2+-NO (hardware ) other sets you may need to refer to schematics to alter the time constants on Am,FM,SSB squelch\agc circuits to alter the timing capacitors to get it as you want. I have successfully done this on the President McKinley Multi-Mode for a much improved SSB squelch action via a simple one capacitor change to add "hang delay" to the squelch switching action . It works very well and no more annoying noise in background,and plenty of delay to allow pauses in speech on SSB ,before mute cuts in. If you have the electronic skills and can read schematic's you can have a fighting chance of altering it on your radio. On old school FM MPT-1320 27\81 some do use FM noise squelch chip part ,so less susceptible to noise spikes opening\closing radio's mute. some can be altered to improve attack or delay times by altering the "timing values"in the squelch switching circuitry to suit needs. Spectrum communications in UK sell a retro fit "noise Squelch"board NS-1000 to retro fit into older cb radios www.spectrumcomms.co.uk/CB_Kits.htm some better brand HF hams sets do allow agc delay\mute adjustments within the radios menu system as well. So there are some solutions to these "squelch"problems Fred Try the software on CRT SS-6900 it may cure your ssb squelch problem Fred. For me on FM CTCSS encode\decode is the way forward for CB radio (just like PMR446 system) nowadays ,something i would like see used more\supported on CB radios ,mainly due to "squelch noise burst"drives me "Nuts" when driving through Cities,Towns and even now Countrysides towns! All the best,nice Vid Rob
Please Fred - can you do a video on , coming back to CB radio , was there in 81 , begin again so info on radio around £160 aerial £50/80 swr meter / power pack , would help me and other
Hi can you please tell me what and how to get rid of the pulsing sound? I have the same sound but it was my smps power supply! I tested it with my oscilloscope and the ripple on dc side? Terrible. A battery power supply is going in next to smooth out the DC power input. Excellent tutorial, subbed and liked 👍 cheers from Australia ❤

I'm the same way, I never use it either. If I used My squelch, it would cut out a few of the Guys I talk with. Good video Fred, 73's from 151 SC.

I don’t see your vids in my subs list mate missed the last few!
yes its happened to a couple of my own sub channels. Dont know why.
you try turnin off your youtube squelch?
Nice to see another vid Fred.....best wishes to all....Bob
Same to you!
Nice one, Fred. Good point made and very well explained and demonstrated!
Fully agree with you Fred
IF I AM TALKING TO A LOCAL STRONG STATION I USE SQUELCH. BUT MOST OF THE TIME I AM TALKING TO MANY STATIONS DRIFTING IN AND OUT SO I DONT USE IT THEN.
Good video Fred. I seldom use squelch at all. the only time I use it is when there is a terrible amount of noise and I use the squelch to quell the noise when I am conversing with another CB radio operator. I don't mind the radio noise really. I am used to it and you do hear distant stations in the squelch sometimes as well. I fully agree with your take on the squelch usage.
Thanks Andy. I think you can miss out on a lot of good radio with the squelch closed.
Excellent video! Thanks 👍 subbed and liked 👍 cheers from Australia 🇦🇺

FM white noise is very hard on the ears. AM/SSB open squelch is fine, but FM - no thanks!
Nice review! Thanks for the interesting info!

On my President McKinley I will engage ASC on AM but the radio automatically disables it on SSB. They probably did it for that reason.
Interesting. Did not though it did that.
Fred in the Shed Me either. I didn’t know why it would do that until this vid. Thank you!!!
ham equipment uses noise squelch so no problem. surprised new cb rigs dont

Pleasure Dale. 10 mins ago i had a fellow RUclipsr contact us from over 600 miles away on our sideband group so you never know whos about.
Everyone need to use squelch at some point especially on FM if your listening all day I've never bothered with squelch when am on AM or SSB that's where I am mostly.
Yep fully agree on squelch but just as annoying is ops not leaving long enough gaps between overs to actually hear if a station is trying to break in.
i agree with you fred when im on side band i never use squelch cause you never know if your missing a possible contact! 73's from 271 western south dakota usa
I agree Fred. Cheers buddy.
Yep I never use it. Plus I'm always Mobil so I need to hear the best I can 👍

SSB needs fast opening but long delay before closing to allow voice "pauses" not shutting the squelch closed to quickly (some sets allow you to alter this feature,some you may have to modify hardware wise to get it right )
FM ASQ(not all uses generally noise squelch SS6900 does)
the SS6900 in pc mode software can be adjusted in the "options screen"

I use thd sqcon FM all time .
ASC Squelches on presidents been opening with great eass .
But jot to use SQ on ssb
I'm not the only one then... 🙂
Nice.........
Please Fred - can you do a video on , coming back to CB radio , was there in 81 , begin again so info on radio around £160 aerial £50/80 swr meter / power pack , would help me and other
Neil If you browse the channel ive made plenty like that already. Cheers
Defeats the object using squelch on SSB! I can understand it on FM but definately not on SSB ... or CW ;)
Certainly with a decent FM VHF or UHF radio, if it is not strong enough to break the squelch, it is too weak to be copied.
Quite right fred youd miss all the dx stations if you use squelch.
👌👍
Hi can you please tell me what and how to get rid of the pulsing sound? I have the same sound but it was my smps power supply! I tested it with my oscilloscope and the ripple on dc side? Terrible. A battery power supply is going in next to smooth out the DC power input. Excellent tutorial, subbed and liked 👍 cheers from Australia ❤
It might be a PLT noise. Very tricky to correct. Get an old AM radio and tune off a station and see if it picks it up.
@@CB-RADIO-UK thanks for the quick reply. I'll give it a go and see what happens.👍👍👍
I would only use squelch on FM because of the hi static noise but that's it......
squelch is perfect on ssb when you have 0% QRM.
I never use the squelch,i didnt use it back in the day either.You are most likely to miss out on alot of contacts.
GREAT VIDEO.../ Can you recommend a antenna for SSB radio..
See here for most popular. ruclips.net/video/vmwvB24EXZI/видео.html
Your not the only one Fred i am the same
Why in ssb there are like only certain channels to speak? 36,37...40?
The midblock 40 channels are all fully legal SSB channels so thats 80 extra. Across 11m there are something like 400 SSB channels.
I put squelch onto full so I don’t have to hear anyone
LOL
I turn my squelch up if I don't hear them I don't talk to them
LOL if i did that around my QTH i would talk to about 3 people max.
