I Did old school (literally in jr high) back in the late 60s?
1750M band.
USA Part 15, 160-190khz 1W max input and 15M antenna ad feed line max
Ran 1w Am input at the base of the 15M pole with a huge load coil and
capacity hat (guy wires from the top straight to trees).? Frequency was 185khz.
If you stay in the band any mode was allowed.? Experimented with SSB too.
In both cases antenna bandwidth limited audio bandwidth!
Distances then were in to 10-60 miles depending on band noise.? CW
at really slow rates (never got good at it) were heard the furthest by a factor of 3.
Other than CW, QRSS and very narrow digital modes? I cannot understand why?
a full up SSB radio is useful for down there.? ? Even at 630 I'm mystified as the
band is so narrow and the bandwidth of the antennas is narrower.
