Galaxy DX-2547 suddenly low output, HELP?
Hi all, I have a DX-2547 that I use every so often and have not used it in a couple of weeks and find that output is extremely low. On AM it puts out about 1/2 watt dead key and swings to like 3 watts with modulation. SSB swings to about 3 watts as well. It used to put out like 8-10 watts dead key and swing to 15 or so on AM and SSB swung to like 20 watts. I am fairly handy and not afraid to try anything, can someone tell me what most likely the problem is or how I can check and/or what to replace?
Thanks for any help...Adam

Hi all, so the radio has 2 finals, IR5620's and I replaced those 2 but no change? Can anyone help? Thanks, Adam

Usually if the final goes the driver will show some output but not like your saying. I would check the voltage going to the finals, it seems to me that is the issue. Could be the internal power supply too, easy check there is to hook it up to an external supply. I think CB Tricks has a service manual with the specs.

Hi, I am running it on an External power supply but it's the same. I am hoping someone out there knows what component(s) it may be. Thanks, Adam

Try outputting into a dummy load and see what your output is.

I only always test to a dummy load. Thanks, Adam
