Guitar_199 , according to what you shared ... Pin 1 and Pin 4 need to be reversed . I'm warming up the soldering gun now . I'll let you know how it goes . Thanks

Hey everyone , I have an RCA Co-Pilot 14T302 that I'm trying to wire an Astatic D104 M6B microphone to ... and I wired it like my Road Devil is , which is : Pin 1. White Pin 2. Shield & Blue Pin 3. Black Pin 4. Red the mic has transmit , but the radio isn't receiving with this wiring code ...

My "Radio Doctor" thinks it might be the microphone ... I'm at such a loss right now ... I have no idea where to start anymore .

The electrolytic capacitors were my first thought . That's why in my first post I asked "Is it Electrolytic Capacitor related , or does it have something different going on ?" . With these older radios , the electrolytic capacitors are almost always the culprit when something goes wrong ... lol

Thanks everyone ... and WOW Andy , you put in some time for researching it ... lol . To answer the 1st question ... I am using a 2m/440 duplexer , hooked up correctly ... and it's hooked up to a 2 meter antenna . I put my FT-897D on the same frequency that the TW-4000a is on . They're both on...

Actually this radio still has it's original stock mic with it

I was testing it out on Simplex to begin with . I'd key the Kenwood up and say my call sign , and I can see the keyup on the Kenwood's display . The audio bar moves with my voice ... but I'm not hearing any audio coming from any of the receiving radios I used (I tested it with a few different...

So I recently purchased a Kenwood TW 4000a , and I realize it's a 30 year old radio ... that's one of the reasons I wanted it . It receives good ... and it has keyup , but no transmit . When I key the mic , I can see the signal bar moving with my audio , but I don't hear any audio transmitting...

The vacuum tube to the right of the circled one is the tube that was changed.

Hi everyone , I know I'm going to feel stupid for asking this question . But I have an old Heathkit SB-102 and it was working fine and then all of a sudden it stopped working properly .When I turn it on , the power only goes as far as the tube circled in the picture , and no...

Thanks Nomad , I let him know and he said he's going to check it out . I'll let you know how he made out once he gets it done .

I have a friend with an RCI 2990 that has an issue which he can't figure out . So I thought I'd ask here , and see if anyone else might have any ideas as to what's going on with it . He says that his 2990 works good on all the modes (AM,FM,USB & CW) like it should . But on Lower Sideband it...

I've been trying to find out what the very first solid state radio was , and I'm having a hard time finding any information about it . Does anyone know who , or what the very first solid state radio was ?

I checked D18 through D21 and they're all in good shape . So any ideas as to what I should check next ? Doesn't this radio have a potentiometer that can adjust the receive for the AM side ?

Thanks Nomad , I'll check those out real quick .

Hi Everyone , I have a really nice Ranger AR-3500 , the 30 watt version . And it works , and preforms as it should , except the receive on AM is EXTREMELY loud . Even with the RF gain turned almost all the way down , stations that were already loud to me , sound really garbled , and other...

Also , I don't find a lot of information about them online . I basically just find Browning Golden Eagles that are for sale , or videos of people talking on them , but very little information . I thought there would be more information about them online with as popular as they are .

Thanks for the heads up on the Mark 4 ... I'm actually leaning more towards a Mark II , to be honest . So any info on those would be greatly appreciated. I'm very familiar with buying older radios . I have quite a few old timers around here , both tube and solid state . I love the older...

Thank you Eldorado

how do I find that video on Youtube Kahuna ? I have a Randy and I'd like to check it out .
