Anyway to adjust this?

Am I missing something or is process to align the radio’s SWR meter not in the alignment procedures? I’m not referring to the simple process of checking your SWR’s. I’m referring to making sure the radio was aligned properly internally so that the external meter will give you the proper results...

I do a little misc work for a cb shop. He lets me use his equipment to do my stuff as long as I’m not competing with him I just do little repairs for local guys and he is all internet sales and service (cbpronto). I don’t bother him with technical questions or I’d ask him…but because he’s really...

Get your money back. Dispute charges.

Check for a short at voltage regulator.

Fairly new Cobra 29 Chrome. The channel display was going on and off. Opened radio. R103 was smoked. Replaced and it fixed issue. R103 (and R104) get extremely hot to the touch when keying up. They are 1 & 2 watt resistors so I expect they get hot but, they shouldn’t burn up. They only get hot...

Where is the FM deviation pot on these boards?

I was enjoying this old thread but it seemed to end abruptly.

I couldn’t get the schematics to load at first. Got it. 10uh 1amp. Got a 2amp coming in w/ replacement caps. Thanks.

This look correct?

Texas Star DX350 (probably the same as just about every Texas Star) None of the parts lists on cbrtricks list values for L1 or L2. I mean, shall I just grab a random rf choke ‍♂️. Needing the value and/or source for part.

Yes. It was strange because the voltage on the the trace on the board that comes from the “switched” leg of that control pot was showing 2.7v. My first thought was a shorted component was drawing down the power. The radio would actually turn on, but dim. Thats wierd.

Meet the two solder pads that should have been soldered together. Held together by a flake at one time.

[edit] Resolved below ⬇️ RX works RX audio does not work The actual volume control pot is working properly adjusting between 0-50kohm approx Tx works Tx audio (modulation and talkback) work PA Audio works when talking in mic What can I provide you with to help fix the issue. I can hear a pop...

Bump

RX works on USB and LSB Absolutely no receive on AM. Needle does not move and no RX audio. What info can I provide? Somebody was in it because the clarifier is open. Side Note: VR13 does not affect SSB audio/power and is over modulated. AM audio is perfect on the scope. Q39 Limiter is in tact.

I don’t want to spend much time dinking w/ this $150 radio but maybe someone has experienced the issue and the fix can be quick and painless. •Final shows 13.8v/13.1 at legs on TX •The transistor circled is super hot to touch all the time, key up or not.Actually, most the caps in the area are...

D85 was toast. Replaced. Works well now. I’m a little baffled at the poor sinad reading though the receive is picking up as well as my Icom though the meter doesn’t like to budge unless there’s a big signal. I calibrated S9 at -67dbm. Two separate things though. Meter could be an issue. Not as...

I will take a closer look tomorrow but I really don’t think there is any carrier whatsoever on the selected frequency showing up on the “sniffing” radio. I will check D85.

No AM TX but plenty of power on FM. Receive works. PA works. I accidentally discovered a small signal at 27.120 regardless of which channel it’s on when I looked up at my bench radio. Signal then checked on spectrum analyzer reading at coax-out and it shows up….low, but it’s there. TP3 is on...
