New member welcome / Hi all

I am new on this forum. My name is Steve, my ham call is KC7BYP, my home QTH is Kennewick, WA.  I am a General class operator. In my 2008 Pontiac Torrent I have a Ranger RCI-2950 and a Yeasu FT-8900R. I have in my shack a Icom ic-730 HF rig, a Kenwood  R-600 short wave receiver and a  Baofeng uv5ra 2m/70cm  VHF/UHF ht. Right now I can only operate HF via an internet controlled remote base. The free Windows based prog is at www.remotehams.com . I use the remote base because I live in an apt and I can't put up any outside antennas. The remote base setup isn't the ideal setup but it comes in a close 2nd. Without it, all I would have for HF is 10 meters in the mobile. 73s

CB Radio Repair Forum / re: a audio feed back loop in a Radio Shack cb radio
« on: April 26, 2019, 06:16:28 AM »
This is in a Realistic TRC-474 CB transceiver.  The receiver is making an audio tone in it when it is turned on. The dash panel lights turn on and the TX is showing 5 watts out on my swr/power meter. But the same tone is in the TX modulation when I have a CB HT turned on, on the same ch. I keep the CB HT as a test radio.  The RF gain and the squelch have no effect. The tone goes away in PA mode. The PA mode works fine.  I don't know where to find a service manual for this radio.

Now I have an AA degree in general  electronics. But I primarily fixed electric/electronic typewriters, fax machines and 1st gen to 3rd gen copy machines. I am also a Ham Radio Operator. I probably could fix this CB radio if I had the test equipment. All I have in the way of test equipment is an Ideal 61-340 VOM and an old Echo portable tube checker. I dabble in restoring old tube radios with my room mates help. Now I can't go sticking a probe in the radio with my shaky hands, I have micro  tremors in my hands and I would probably short out something, that's why I had to retire. But my room mate knows enough electronics to be my hands, I tell him where to stick the probe. But without more test equipment and the service manual. I would only be guessing. I could use some help please.

Steve
