Looks like a winner.

Nice

I fix them like nomad I have a bunch of them out on the road and have not have one fail. I also use a bit of Flux in that situation.

He does not have a phone number or a way to get a hold of. Only through face book. He is not real. And for a guy in business he has a awful lot of time to play on the radio... = Not Busy.

Probably me if any was done at all. One or two say Doc under the lid.. one says doc under the lid has a chipswitch and week final.

Plus shipping

I do not feel the need to collect radios anymore. I have 7 or 8 Mostly HR2510's and a couple Lincolns. If I remember correctly about 4 have Chipswitches installed. A couple come with factory or Realistic HTX100 microphones with up and down buttons. But they seem to sound best with Astatic...

Nomad I have a question. Are the double diodes used in most of the older sideband radios on the clarifier section? If so when they are missing what would the factory part number be for the double diode? And what would the outcome be if they were replaced with a 1n4148? and are these diodes still...

I am with the positive on this Mic. I may still have a couple kicking around here and always thought they had a deep clear sound.

It must be Sam's 121. It is a MB8719 PLL. I believe my new problem is a bad solder connection. AM floats all over while SSB stays in tune. All modes can not be set to the specs in the Sam's 121. Someone was in this radio years ago. Unlocked the clarifier and did it wrong. They may have moved or...

So I found a schematic the test point is the emitter of TR20. I am still having problems. First of all I am not using the right manual for the radio. I am using Sam's 221. I do not think the frequencies are correct. I can align it by zero beeting it against a known good radio. Of course I have...

FM has a harsh static that I don't want to listen to.

Another cheaply made cobra with a channel encoder the size of a small potentiometer that will last about a year. Add a push to it and maybe they will now last 6 months.

No. Already did that. Only TP 9 and TP 10. Tried all jumpers in that area also

Uniden Grant gray plastic faceplate. Board number PC409AC. TP21 ( L21 secondary) I am lost and it probably is something simple

Yes needs a alignment. I actually just fixed a botched attempt. I have had this radio probably 10 years. Bought it for parts not working. It was way off frequency. Who ever unlocked it removed and cut wrong parts. And did not jump anything. I had a 148 GTL same thing. But that was easy I know...

After reading a bunch of different clarifier mods and putting bits and pieces from a few together ear it is. Clarifier unlock Uniden PC-409 AC Board. Cut or remove R148 Cut or remove R44 Cut or remove D52 Jump R174 Change R175 to a 1K ohm resistor. Orange wire on bottom of clarifier to...

Nomad these are old radios but would you remember how to get more adjustment for AM? The slug is at the bottom of L23 and I need to raise the frequency a bit. It is right at .50 when cold bet goes down to .48 or .49 when hot and the slug is bottomed out. I don't want to but may have to put a...

Yes same board. I found a couple things I am going to look at first. Thanks
