Dave,
Today I got a Micronta Fet VOM that is analog and high impedance. So I go do one final alignment on the receive. Much easier with a needle. So what happens in the middle of the alignment? Truckers start coming thru the radio. And with no antenna and a dummy load, no less ! ;D ;D

The TRC-450 had a much more frequency modifiable chassis (same as the Cobra 142 with the MB8719 PLL). The TRC-451 was not frequency mod friendly with the uPD2824 ROM-coded PLL (Same chassis as the Cobra 146). BUT, the TRC-451 was a great performer. Receive sensitivity was outstanding, and the noise floor was very low. Noise blanker was excellent, and transmit audio was stellar on both AM and SSB. So if you're happy on the regular 40, this is one great choice. I like mine

Dave, Good news. I have ironed out all the problems except the meter is still DOA. All hums and noises are gone. Radio checks are superb. Will work on the meter problem. Can I manually test the meter by connecting a DMM across the pins? I have fixed dozens & dozens of these meters by simply loosening the tiny phillips head screw on top of the meter.It has some clear very thin plastic across the screw.Turn it counter clockwise for about 1/2 of a turn & try it.Some take a bit more of a turn but don't turn it to far or it will fall out.It is a simple fix.It requires removing the case,removing the two screws that hold the face plate on & removing the knobs so you can tilt the faceplate forward so that you have access to the tiny screw.It really is simple & removing the case screws takes more time than the fix for the meter.It works I'd say in 90% of all radios I have had with this issue & is far simpler & cheaper than a meter replacement.
