If you remember I did ask you if you had that switch on? Good that is that it was.

Ok, best I can remember the filament voltage is mostly isolated from the rest of the radio simply meaning there is either a break in the voltage supply or the heater switch is faulty or there is an issue in the AC line plug that connects pin 9 to pin 11 which in turn delivers the 12.6 vac to the...

I assume the heater switch on the front is on? Just making sure.

Does it Receive? The reason I ask this is because there should be an accessory plug in the back next to the SO239 antenna plug if it's missing it will not allow the tubes to get filament voltage if the seller is a tech he may have done a cold neutralization adjustment and forgot to put the plug...

Does it Receive?

I have worked on hundreds of these over the last 50 years but when you say shipping damage what are the problems physical/electrical or both? I'm in Iowa just for the record.

Well, I read through its entirety and really didn't find any factual errors it's pretty straightforward forward I have been repairing since about 1969 and have with maybe a few short years in the commercial field but it seems pretty accurate. Of course, one could argue that there is much more...

Citizen Band (CB) radios have played a significant role in communication over the years. These radios, operating in the CB radio spectrum, have been used by people around the world for various purposes. In this essay, we will explore the history, uses, and impact of Citizen Band radios. Citizen...

I just got on CBTricks seems to be working fine

Well, you can't even begin until you reinstate control panel voltages and get the displays working and when you do you may find the radio coming back to life. You may find a bad connection or switch or something but first fix the lights.

So is the noise the fan or is the noise there when the fan is turned off and then when you turn the fan on high the noise increases? If you have any ground looping in the antenna system or the DC power distribution those will all add to the issue. Now if the alternator is the issue and any of...

How do you know the alternator is making the noise? Next, it is very hard to control noise being generator by using a long wire with a suppressor that far from the Alternator if there were any chance of doing that it would most likely need to be done at the alternator. I assume the noise you...

Ok I usually only make 1 mistake a year that was 2 mistakes unless I'm counting wrong then it could be 3 mistakes, but in my defense, I don't really care where he is I just remember watching one of his videos after being made aware of his channel and I never went back for more.

There are factors that can cause what you are talking about some of them are simply that the buffer stages in some radios are just dirty IE harmonically and although all IF and mixer stages in low-end radios IE "CBs" can be dirty you will most likely see a lot more of this kind of issue with the...

So it most likely isn't adjusting freq. on any channel?
