R2660 - Spectrum analyzer ghosts (internal signals)
Posted: Tue Apr 15, 2025 11:07 am
Hello members, I have an old R2660 (IDEN optiion) that I replaced all the 33uf electrolytics caps on Interface board ( each one had leaked). Luckily no major damage that didn't clean up. This fixed the alarming of the "excessive power to internal load alarm". I'm waiting to receive and replace the CMOS battery as well. It goes through all calibrations successfully. Everything seams to be working ok except I'm seeing all kinds of internal signals in spectrum analyzer mode (no antenna connected). It does receive signals normally when connected to an antenna.
Does anyone know what might be causing this? More bad electrolytics on another board?
It what quite a job replacing all those things too i must say...
Thanks in advance
