I am considering replacing the SSB and AM filters in my AOR AR8600MkII with
the optional Collins filters, so I am seeking feedback on whether or not
this is a worthwhile upgrade. To anyone who has done this upgrade: What, if
any, improvements did you notice in HF and/or AM broadcast performance? I
listen to HF amateur comms (including SSB phone, CW and decoding of PSK31)
and SW broadcast fairly regularly...could I expect any major improvements in
those applications with the better filters installed?

Also, the AOR technical bulletin on the optional filters warns that the 6
kHz AM filter may be too narrow for HVF Air Band use ("where the centre
frequencies can be offset by a few kHz"). Has anyone encountered such a
problem?

Thanks,
Doug
