I wonder if I could drop in an MLCC ceramic in place the electrolytic: TDK?FG14X5R1E226MRT00 for example would have negligible ESR and parasitics well past 100MHz. Definitely added to the list to check out ... I also have a new IF buffer circuit to put in (panadapter), and a new backup battery case.
I wonder if there other pin-diode switched circuits (shared xmit/rcv circuits like the filters maybe) that are also ticking "time bombs"?
