What after market filters are being put into the R-75? I want to add a 9mhz and a 455khz and I'm not sure what the best choices are for AM and SSB....Thanks for your input!
I'd put in a 2.4 or a 3.2 kHz filter, depending upon what you mostly prefer listening to. The 3.2 makes for improved synchronous AM listening in crowded band conditions.
