    Galaxy dx2547 modulation limiter location

    I put a 2sc945 out of an old washington 8719 parts chassis I had. Fixed the AMC. I tried the ALC pot and it is in fact working. It just doesn't have the adjustment that I am familiar with. It's almost like it does nothing the first 3/4 of the way then its on. Kind of the same with ALC. But they...

    Galaxy dx2547 modulation limiter location

    Looks like q57 should be there and is supposed to be a 2sc945. I'll put one in and see what happens.

    Galaxy dx2547 modulation limiter location

    They are stock. Looking at the trace side everything looks clean. No hacked solder work to point me. Just where the board is marked q57 looks a little like melted Flux but clean and there is no q57 in place.

    R264 and q39 are both in place.

    Galaxy dx2547 modulation limiter location

    Picked up a dx2547 that I believe someone removed the limiter as it is way over modulated in AM and SSB with mic gain up. AMC and ALC pot has no effect. Any pointers where to look for a snipped or removed component? Model with switching supply and mosfets ept069611a. Looks like q57 is missing...

    And be very careful. You are playing with high voltage.

    Tram D201A help please-tubes light up but nothing else comes on

    That brace looks to me that someone pushed on that board and it fixed an issue of bad connections so instead of the correct fix they pushed it to that position and glued that brace to keep it there. Quick fix but I would seriously inspect the entire area as it is a known problem spot.

    Tram D201A help please-tubes light up but nothing else comes on

    If you know 100% for sure the radio was working before being shipped then something banged loose or cracked. If you are only guessing it might have worked before shipping then you are chasing the unknown. That radio has so many resistors that take abuse and the circuit board disintegrates. So...

    That means your synth is putting out. So that's good. Did you check all the connections at the bottom of the ba board and pins?

    I see several mods that were done. A couple of I think 455khz filters on bottom side not factory.

    Pretty weathered. First things to try Is pull the boards and re-seat them. Pull relay and re-seat.

    Tram D201 VFO drift fix.

    You want the best way to solve that problem and sound great on 38lsb. Go to Barkett and buy the 38 crystal. Put it in ch1 slot. You now have a few new SSB frequencies and you can use the vfo for AM on the ch you lost. Set it dead on using the trimmer. Works like a charm. Thats the way I talk...

    Solar panels

    Also, if you are considering solar from a cold call that's a bit foolish. If you want solar I suggest you do a ton of homework and search out a company on your own. Nothing good comes from cold calls except a paycheck for the person on the other end.
