Rick, thanks again. I will check those values in the morning and go from there. I dont have another CB to test the TX but I think my programable scanner covers the CB band so I will check TX too. I will let you know. Chris.

The voltages tested are as follows: R12 - 8.51 , 1.66 R15 - 8.51 , 8.33 R18 - 8.51 , 8.44 R26 - 8.51 , 0.55 R32 - 8.51 , 1.58 R42 - 8.51 , 0.69 R43 - 8.51 , 1.47 R127 - 8.51 , 0.08 FET2 = 12v , 1.3v , 0v TR8 = 1.45v , 7v , .74v I got a reading of zero volts on TP1 in both RX and TX. Here is probably...

Rick, thanks for setting me straight. I am used to working on AC powered antique radios. I will re-check those values (the right way this time).

Thanks again Mike. Any suggestions on a good quality noise cancelling mic?

Forgive my ignorance but I cannot get a steady voltage from any point in the radio. For example, when I touch the negative lead of my meter to the frame (ground) and the poistive to a point such as R12 or TP1 the voltage on my meter starts out very low and goes down quickly until it reaches zero vol...

I read somewhere online the favorite mic for truckers that would work with a Cobra 29LTD and cannot find the info again. What mic would be a great match for this radio. This is the older 29 with the side mount mic jack. Thanks.

Rick, thanks. I will check those values and let you know.

I recently found my dads old cobra 29ltd and wanted to use it in my truck. I purchased a new power cord and tried it and the recieve seems to be dead. There is a small hiss that is hard to hear from the speaker when the mic is plugged in. When the mic is keyed the Green led goes to red and the needl...
