Galaxy dx55F High SWR and warning light.

Using dummy load or antenna (both of which are at about 1.1 swr) this 55F shows between 2.5-3 swr and the warning light lights up during modulation. It’s only in this radio. Coax is not an issue. I’ve even hooked up directly to the dummy load and the ship Antenna. The higher the carrier, the higher the SWR. Out of the box the carrier is about 12w AM.

I’ve reflowed traces around coils, antenna hookup etc.

There is not much info on these boards EPT DX2912Z.

Pronto, sounds like you've got a streak of bad new Ranger built radios on your hands. How's the power, and all other functions? How does the swr board look? I'd pull it and check for bad joints etc if it is were me. There's the vr on the swr board you can get to through the access hole on the inner side if it's out of adjustment.
 
Yes sir. I believe this is the 3rd new radio in the last month. It happens.

I’ve never had to dink with the board. Does the VR calibrate the warning light or the meter itself? I suspect if it calibrates the meter, the light will take care of itself.
 
Just got back in the shop. Will get to it shortly. Thanks!

***REPAIRED*** C257 crushed

(Oops-I don’t think I got the pic of c257 location in that graphic but it’s behind the swr board)

This was strange. Adjusting the SWR board did nothing. The board and pot were fine. After removing the board, I could visually inspect the main board. C257 was crushed. I don’t see how this radio passes inspection.

Works perfectly, now. I imagine it happened when Galaxy connected the board to the chassis. There’s no way to access it once that SWR board is installed.

Qc just isn't there anymore... One of the biggest complaints I have when I talk to John at galaxy. I think the person that puts the inspected stickers on just walks down the row and slaps em on there for looks. Glad you found it! Just out of curiosity, was the swr vr adjustable after replacing the disc cap?
