Hello Carl
All very interesting! I still see a huge increase in distances as
nightfall moves in, but all of the extremely distant stations are picked
up at the upper end of the NDB allocation close to 400 kHz. During the
day a good haul is Schenectady, NY to the west. For 25 watts that is

First thing, 160 meter is NOT the Topband and hasn't been for a number
of years. 2200m is the Topband, with 630m in second place, and 160m a

For a given electron density profile, the amount of refraction incurred by

The result of that is the lower the

Hello Topband propagation experts,
I have been messing around with listening to low frequency navigation
beacons and wondering how reception on 200 kHz relates to 160 meters.
Not sure there is a correlation. I have been listening on my 1942

Many of these old transmitting mica capacitors have reliability issues.
Their foil-mica technology is very obsolete and their molded enclosures
often leak moisture and contaminants. On the good side, unlike many
other capacitor designs they're capable of the handling high currents

I live in California (and have for my entire life). Practiced law for nearly 35
years.
The California legislature is filled with decent, and well intentioned public
servants who are also naive, lack perspective and business sense, and don’t
have a clue about the big picture or unintended
Hey I'm in 6 land the fruits & nuts are in the legislature too! Don't cheat

We lost Mendelson's in Dayton Ohio. Great place for all sorts of stuff. I spent

All you need to know is that it's from the California legislature, which is just
like granola. (Take out the fruits and nuts and you're left with the flakes.)
