Filters for the KBPF3

VE3WDM

I am considering the KBPF3 general coverage receiver option, I have the following filters in the rig 2.7 5 pole crystal stock filter, 8 pole Inrad 500, 400 and 200hz filters. Do I need to consider any other filter options if I do purchase the KBPF3 module?
Thanks
Mike

Don't think so, unless you want to receive signals wider than 2.7 KHz

Mike,

You do not *need* to purchase an additional filter, but you may want to.

If you want to listen to AM (not AMsync), then you would want a wider
filter - with AM, you need to have enough room for both sidebands and
the 2.7 kHz filter will limit the highest audio frequency demodulated to
about 1.4 kHz..

If you want to also transmit AM, I would suggest the 6 kHz filter, but
if you never will transmit AM, then I would suggest the 13 kHz filter
for SWL purposes.

Sync AM can use the 2.7 kHz filter because only one sideband will be
used at a time.
