Thanks everyone for the replies. I don't think it's a case of reversed cable plugs. The radio owner informs me the unit was working properly when removed from his vehicle, but it was when he later tried using it on his base station that the odd symptoms first surfaced. Any others thoughts on...

Hello everyone. A 929 came across the bench with a strange issue - No TX whatsoever, and RX only comes up when the Dimmer Control is turned all the way down. I was wondering if anyone had seen this before and maybe knew of the fix. Could it be a power issue? Maybe it is starved for enough...

Hello everyone. One of these radios came across the bench the other day with this odd issue: AM receive is about 7 KCs down from transmit. I checked the synthesizer alignment (with Clarifier centered at 12 O'clock), and every adjustment was spot on. AM transmit frequency is correct. SSB...

I'm doing a little restoration work on a couple of old tube CB radios and need to perform an alignment. Does anyone know of a way to dissolve the factory substance that was used to lock the tuning slugs into position? Hoping there is something available that will remove it without damaging...

I have two Washington and 1 Lafayette SSB-100 CB base stations exhibiting the same problem....receive audio sounds restricted, almost like the speaker is old and dried up. Transmit audio is unaffected. Symptom persists even when using known quality external speakers. Re-alignment had no...

Thanks, Inquietude. After I posted the question I dug out the Sam's for the 25GTL and saw that the board hadn't changed much over the years. I did exactly what you suggested in your reply, sans the toggle switch. In my experience I've never found the ANL to be much help, so I jumpered a...

Hello. It seems the new Cobra 25 LX has a full-time ANL with a switchable NB. I prefer the cleaner receive audio when a radio's ANL is disengaged. Is there a mod I can perform that will disable the full-time ANL while leaving the NB switchable? Many thanks for your service.

I recently expanded the channels on my 2547 (the PLL jump) and it's working well except the receive sensitivity drops as I approach the band edges. I can't seem to compensate for this using the alignment pots. Does anyone know if there is an additional modification available for improving the...

Hello all. I've pulled a major screw up on my 2995. I was going over the alignment procedure - specifically, I was checking the Driver and Final mA settings and when I went to remove the test lead (aligator clip) from TP7, I accidently shorted TP7 to ground. A small puff of smoke from, or near...
