Would you consider building a simple L-C filter consisting of a couple of
resonators?
This would help to reduce the potential high amplitude spurious responses
present on the high frequency side in the 8215 kHz to 15 kHz mixing process.

I have filters from 2.7 kHz narrower in my K3. It just
doesn't sound good on AM receive. Isn't there some way to
widen it out on AM without buying AM filters I'll hardly
use?? I have some AM transmitters so I'm not worried about
TX.
I only operate AM a few hours a year.
Tom,
Unless you add the 6 kHz or the FM filter, you will have to use SSB or
Sync AM to receive those AM signals.
Any other method will restrict your AM passband to less than 1600 kHz
for the highest demodulated frequency.
If you want to transmit AM as well, you must have the 6 kHz filter.
73,
, finish your transmission, then clear the error code after
you unkey. I am sure there are unspeakable things happening transmitting AM
through that filter purity wise, but I figure if they put those boatanchors on
the band, comparatively - it works OK. YMMV Don...
