"AM overload"

[N8YX]

Yes, one CAN discuss those sorts of things over here, particularly when they're of a technically oriented nature.

'DEY, if you come across this:

Have you had the chance to study your '897's IF scheme? If so: Do the signal paths in AM and SSB differ significantly?

[KC2UGV]

Here's the technical manual for the 897: http://www.arcticpeak.com/files/FT-897%20Technical%20Supplement.pdf

On page 8, it describes the scenario that AM and SSB signals don't diverge until after the second IF circuit, and then are fed into the demodulator circuit.

Does this help?

I see a low-pass filter in the SSB RX signal path that isn't present in the AM RX path... :chin:
