Greetings All !!

I am a retired broadcast engineer in Huntsville, Alabama.

I just recovered a  poor Harris SX-1  AM transmitter from a site that
bought a new transmitter. Rats have chewed the wiring and many circuits need to be reconnected.

One of the "good things" for commercial use , but "bad thing" for ham use is that the transmitter has two narrow tuned circuits .. one series and one parallel tuned to the desired frequency.   This keeps it "clean" for broadcast , but doesn't make for a multi-frequency 160 meter rig.   

So, I'm wondering what crystal I should order to retune the transmitter to 160 meters.

For the "mid-south"  .... I'm in North Alabama .. close to the Tennessee line, what frequency is the most used for my region.      Do other AMers  tune the band looking for contacts on frequencies other than the ones that they transmit on ?

I haven't been on 160 for over 40 years, so I really am a newcomer.

Thanks in advance

There is a lot of activity on 1885, at least around the North-East.

From your location you could choose from either 1880 or 1885. '85 seems to be for the East Coast gang and I call 1880 for the mid-west Ham ops. During the winter there is slight interference for me cuz I am more or less in the middle of the two. But it is tolerable.
Those are the two most popular. 1945 and 1985, as mentioned are used but they get SSB use too and may not always be available.
