Galaxy 2527 SSB receive sounds mushy

[Staybolt]

For some reason my 2527 sounds crispy, crackly, and distorted on SSB. Almost like the AGC has been cranked all the way open. Anyone have any hints for me?

Sounds like its time for a frontemnd over haul schottky diode swap ETC

Okay what parts do i need to replace?

Thats for the 959/949 this radio uses the RCI 2950 board..

D1, D2, D34, D35 replace with 1n6263 diodes. this is for the old 2950 radios.you said yours has this board in it. before I did much to it I would make sure it is aligned properly. since you say it is only on SSB

LOL! its okay!
I found a kit on Ebay that uses shottkey diodes.. I already have the parts.

Did that 'mushy' condition come on suddenly, or has it always been that way?

If it happened suddenly, then a part may be failing.

If it has always sounded that way, it would be best to ship it off to a real tech and give the radio a complete alignment.
Any radio will always operate better in TX and RX when properly aligned.

That diode changeout - while beneficial - will not cure the problem.

Robb ,since it only does this on ssb I am leaning more to check the alignment 1st also. the diodes would act up om am also.
