Gatekeeper In Amp Building 102 - Keying Circuits

[@frppower1]

Dear gatekeeper, my name is Chris, I’ve been in the cb hobby for only about two years now, and I decided to build a little 2-pill amp , with help from guys like you and bbi I was able to accomplish it, I put videos on my profile on here, I can’t thank you enough for taking the time to put all the teaching videos on here, I spent days studying your videos and taking notes, just wanted to thank you, I wouldn’t have been able to do it without your videos, thank you so much

[@1883GotDown]

Feel free to support check out my description at the bottom only if you wish not asking you to bud.

[@jessiec4128]

I am so glad you added ssb to my little one pill. I really appreciate you helping me. I will never let anyone use my equipment. I wish I could have found how how my friend destroyed my amp. Then you helped get it straight, and added the SSB for me. I really appreciate your help Big Time. I am going to try and build an amp. I will need help on the keying part done, and try to remember how to add the SSB, which I really like talking on SSB.

[@morsecode4666]

Could you please put a detailed list of the components. First value of the polarised capacitor.

I JUST STARTED WORKING ON A IDEA OF MINE AND SEARCHING ON WAYS TO MAKE IT WORK.THANK YOU I AM GLAD I FOUND YOU.

Thanks bud...Just wanted to let you know I am releasing videos again...if you haven't had a chance to check them out make sure to, and come down and leave me some comments, thumbs up, etc...because it helps with KZbin algorithm to help me get scene. Thanks a lot buddy!

Now I understand it a little better.keep doing videos like this gatekeeper.225 Rajun Cajun waving from the swamps.73's

[@RC-Heli835]

Gatekeeper this is absolutely spectacularly awesome! I wish I had an amp to build and install one of these little keying circuits in like maybe a 1x4 base amp that runs on 110 ACV.

[@1883GotDown]

All it takes is money brother. Im guessing you have never owned one before? I love being the first for people. Ill do you right. You can contact me at [e-mail]

[@jonbuckiflyer8800]

Thanks GateKeeper- you've made this easy to understand. This is a good instructional video, and many of us newbies certainly appreciate your time here, and sharing. Thanks again- 👍 P.S. I understand you've been busy lately, so hope you see my email soon. Thanks-& 73's "Keep-em coming- sir!..

Hi. Nice videos. What is the purpose of the diode? I have a 2pill mrf455 amp with a built in pre amp. After a while on tx while talking on SSB the pre amp relay starts to chatter (if turned on). Wondering why and why it takes a short while to start happening. After watching this wondering if it has a cap to help hold the smaller relay closed while on tx.Didn't remember seeing one. I'll take another look.

[@URSOAKINGINITMATE]

G'DAY GATEKEEPER, I WAS WONDERING WHAT VOLTAGE AND WATTAGE ZENER DIODE I SHOULD USE IN THE KEYING CIRCUIT? GREAT VIDEOS...KEEP UP THE GOOD WORK MATE.

[@simonkirby5724]

What coax are you using to make connections to relay?

[@1883GotDown]

RG 316

[@225rc]

Teach more about the inside of amps,I would like to know how they work more than I do which is not much.

[@chrischristie6202]

What value transistor did you use on your transmit led ? I want to try that but it lights with just the radio also when I modulate. Want it to only light when I key the box.

[@1883GotDown]

not sure how you habe yours set up man but it is simple... use a 1k resistor put neg lead on neg of relay...pos led on pos switch on of main switch. You need to have it on a switch. then it will be transmit

[@bobicpfan2]

I reckon the jumper on the relay could also go on the pins below it as well right since each side is connected when the relay is off? i just looked at an amp of mine and i noticed the jumper is not where you have it, but one row below

[@1883GotDown]

It is because the relays are different pin outs

[@robertmeyer4744]

great job on a basic key circuit. many different transistors can be used. like 2n3904 2n4401. old Texas Star use PNP transistor. i copied a Palomar key circuit with 2 transistors. has + out when RF present being a tip 3055 can drive big relay to ground and bias supply . there is many keying circuits.

[@1883GotDown]

robert meyer indeed...the latest one I used with my ldmos build was very cool using an opto coupler...the internal darlington pair drove the relay...completely isolated from the Input RF Source :) I have to say that you are the most active commenter on my KZbin videos and I want to thank you highly for that. Stay tuned in because here very very soon I'm going to be releasing all of the work I've done in the last year

[@micro4329]

Hi yes I have a optocoupler keying circuit a fit kit I ordered from our mutual friend n have it put together but been busy n haven't got it booked to the ldmos amp yet would love to see a video on hooking it up to an ldmos amp thanks for the great videos 43 gone. 73

[@51nw]

what are your thoughts on using this type of keying circuit on big amplifiers like a 32pill versus direct keying the relay with a foot pedal etc?

[@1883GotDown]

Honestly its best to go to a bigger transitor...its ok to use this transistor for up to a 16 or 24. Its the relays coil that dictates this not the input of rf. You can look at the dataset of a 2n2222a to see how much amperage it can handle but just to be safe id use a bigger one

[@jim5570091]

What PF ceramic cap would key at a lower input wattage? Say 1/4 to 1/2 watt?

[@1883GotDown]

Use a 10pf either way

hello buddy I will be very soon buying from you 4 match 2879's could you help me with this on how I can order them from you? I bought an amplifier but pills were not matched and 1 burned...do you also sell all parts for building amps or just the transistors? I may need some other parts since swr to radio is killer...again thanks for your videos they are very educational...
