First of all, Neil’s simulation is great.
And I love the network logos.
Most of the longwave Part 15 experimenters
use morse code or various digital modes.
I don’t think too many people have tried AM
between 160 to 190,
so we should definitely give it a go. I believe
this to be quite a bit harder than Part 15 on
the AM broadcast band, but who knows what
we may come up with. The 13 MHz project
has shown that we can work together making
things that nobody has ever done before. And
the new carrier current info on the board is
probably going to eventually get a bunch of
us doing that, so the more the merrier!
There is an absolutely wonderful radio source
called “The Low and Medium Frequency Experimenters
Scrapbook. It was written by the late Ken Cornell, W2IMB.
He had 10 editions, starting in 1972, until about 1996,
when he passed away. This book is very fondly remembered
by many people, but almost impossible to find. If any of
you guys out there have it in the attic, or something, it is
a real treasure. I used to have the first edition, and it is
I just got off the phone with an old buddy who had a longwave
morse code beacon (cw) on 184.0 kHz about 20 years ago. It
was heard in five states, but remember the states are very
small up here. I think the furthest reception report came from
New Hampshire, and he was in West Hartford, CT. Power was
1 watt DC input into the transmitter which fed a 50 foot vertical.
He also had a medium wave morse code beacon here on 1625 kHz
Power was 100 mW. The antenna was 3 meters. This beacon was
also heard in New Hampshire.
My friend had one great great advantage. He set the beacons up
at an old AM broadcast band transmitter site. The tower was
down, but the ground system was still there. So he had the
use of a real broadcast station ground system.
There was no power at the site so he put up some solar cells
and charged a battery that ran the beacons. When I think about
it now, it was a really cool project.
