I know the AEA PK-232 used 200 Hz, as well as the Heathkit HK-232, but the Kantronics KAM series all used 170 Hz shift. That was the reason I switched from the AEA to the KAM products.
What Kantronics models used 200 Hz shift? 73 de Bob - KØRC in MN ----- Original Message ----- From: Jose A.

I have a Communications Quarterly issue from the mid 90's somewhere here in which the author modifies its filters for 170 Hz and describes a great improvement for AMTOR...but also becomes almost useless for 300 baud packet. AM7910 modems have 200 Hz shift.
