With no antenna I have a weak bird at 14.221.5 +/- ...Don't hear it on
my other
transceiver. I changed from switching ps to Old School ps and no change.
Is this
normal? BtW with my vertical antenna and present band conditions, it is
totally inaudible with the antenna connected.

Sadly, this is often untrue.
Get Dan's (AC6LA) program at: http://ac6la.com/tldetails1.html and run some
examples.

Why don't you just buy a10-tube superhet in a large walnut cabinet with a cloth
speaker grille and an amber back-lighted circular dial driven by dial cord and
ganged capacitors? Maybe throw in a magic eye tube. :-)

What is interesting is that while the station runs 50KW on 1550 KHz, it is
daytime only.

I don't know about the we part but at my QTH there is often a nice propagation
peak to the west at, and after, my sunrise. At my sunset I see no such thing.

ot;Hey my wire isn't a vertical, it's
mostly horizontal", I say, if your radio is sitting on a boulder or the ground,
it's a vertical and your wire-on-the-ground counterpoise proves it.

So you make some contacts. Good for you, maybe you're having fun. However, I
submit that you (and I) would have more fun with better antennas.

a
Zepp feed why not use center feed?
If maximizing far field strength is of no concern then I recommend a 50 Ohm load
on the output of the radio :-) You could crank the power down to save the
battery and it would have no effect whatsoever on the signal strength at the
receiving end. A win-win!
e wire which it really is, because
it's going to radiate, but never mind that. In this case, the antenna is a
"sloper" whether it is called that or not. If one end is higher than the TX
then there is a vertical component to the geometry and the radio chassis is the
"counterpoise.
etty impressive, but
nothing like NAA in Cutler, Maine.
