Thats a great thought!!! Do you have any opinions on a good low current 12vdc relay?

When you repaired them did you install a new switch? If so, was it as big of a pain as it looks like it would be?

So, there is a challenge with that even if I could get one. The amount boards that need to be unsoldered just to get to the solder points of the board mounted switch is significant. The operator does not want to spend the dollars for that amount of bench time. If there is a way to clean it...

Hi Everyone, Well, I was able to spend some time at the bench today and the issue IS the power switch. The feed side of the switch was 13.74 volts and the power out side of the switch was 2.4 volts as measured at J401. When I jumped out the 2 pins the radio turned on and turned off when the...

Thanks everyone for your initial replies!!! I am out of the office for a few days for work. I will let everyone know my findings as soon as I get home. Thanks again!! I will say that the power switch option does not make logical sense as it takes "time" to actually turn on but it is worth...

Good day everyone, On the bench today is a 94HP and it is very flaky. The operator said that about 2 weeks ago the radio would not turn normally. It will sometimes turn on after a few minutes and sometime not at all. When I tried it nothing happend right away except for about a 20ma current...

Well done!!!!

Hey Gang, My 1980's HP "battleship" spectrum analyzer bit the dust so I am looking for ideas for a replacement. At this point I am not looking to spend $1000+ for one and am leary of some used ones I see. The truth is, all I have been using it for over the past few years has been the 54MHz...

Hey Ron, I hope you are doing well!! I have been out of town for work so soory for they delay. I actually have been able to get a replacement element for the mic so it is back up and running. Regarding the amp, there are enough amps on marketplace and E-Bay so hopefully you can pick one up...

That's a great question SuperLid!!! The radio does receive on all channels but 40. I wonder if the PLL voltage is to blame???

This is great info Nomad!!! Thank you very much. I'll use the scope to see if changing this makes a difference. Now, to get a night at the bench...that's the trick. Thanks again!!

Hi Everyone, So, on the bench is a Tram D62 which is the same radio as the Cobra 132 and is shown in Sams 179. This radio performs well overall but is sparatic in transmitting on 36, 37, 38, 39 and will will almost never transmit on 40. This is true on AM, LSB and USB. When you key the mic in...

I am not a collector so many radios I buy and fix I sell back into the community. I really like the local operators I get to support and its my "ministry" to the community when I am able to do it. I try to keep the cost reasonable so they can afford it and I can continue to buy parts as needed.

Hi There, I am still the area repair guy to a point. I had to take control of my time and what I was willing to take on. What I mean is that I am not currently taking on a radio that is butchered or the ask is some crazy mod. Also, I will not take 5 radios from an operator with the ask of...

You are very kind for the offer!!! I sent you a PM. Thx so much!!

Hi Everyone, I have a Robyn SB520 that I am repairing and the 7.7975 crystal is bad. How do I know you asked? Well, I could not get it to give a stable frequency during alignment so I swapped it with one from a known working radio and it aligned perfectly. I then took the "bad" one and put it...

Like many of you I have a few radios to choose from. I currently use a Cobra 139XLR and a President HR2510 for 10 meter. I have a good selection of mics but I LOVE my Turner +2 on most radios. I run a Texas Star 350 when needed and power it with a Pyramid PS-46XK. I keep my eye on my MFJ...

I am restoring my Hallicrafters 38D receiver (tube set I picked up in 1980) and needed some caps I did not have in stock as I do not work on tube stuff very often. Next up will be my 1977 Technics SA-5570 stereo (more caps I did not have) so it turned into "I guess I should just reload...

The best Christmas ever!!!!!
