reason why ARRL DXCC should not allow valid DXCC
This is true ,I contract for quiet a few AMs and FMs that can't
find anyone that want to be on 24/7 call. There is this "thing"
called FCC Yearly NRSC Tests where an engineer with an analyzer checks
the spectrum and the station(s) must meet spectral purity ... ie: no

Back during the "Cold War" ( mid to late 60s- early 70s ) I talked with
a lot of Russian hams on 15 meter AM. We were in agreement that our
concerns were family housing, fixing our old cars, education for our

We had a 1550khz in town and a 1450khz moved 2 blocks away from 1550.
Yep mix products on 1650khz and 1350khz. ( and to some extent
1500khz )
a simple 1550 notch on the top of the 1450 transmitter eliminated the
mix products and didn't bother the 1450 transmitter.

If the AM signal is 3x wider than a normal AM, you can be assured that
it's coming out of the transmitter and being tripled both in carrier
and sidebands.
If it is a "mix" from another transmitter or internal to the receiver,
it will be normal bandwidth not three times as wide as a
