I meant NA4G, not NZ4G. Old Fingers syndrome, I guess.

I've forgotten who wanted to know this, so I am posting this info to the
list.
I had said that a catalog I had listed 2 HP 110 VAC single phase motors
for $30. I was wrong. My memory failed again.
These motors cost $69.95. Original cost is $287. What these are are pool
pump motors. They are rated for 115/230 VAC single phase, 22/11 amps, 3450
RPM, 1.0 service factor, class B insulated, thermally protected, shaft
1/2" diam x 1 1/2"long, 56Z frame, original PN C48N2A1A1, MECI part number

Subject: 811A Hartley Recap
I've had a bunch of questions about the experiment with the 811A in a
Hartley. I haven't had a chance to do any more with it other than the
"quickie" test I did last Sunday just to see if I could see if I could get it
to kick into oscillation reliably when keyed. My experience had been that
most times it wouldn't start up. What got me wondering was one time when I
was reaching over the top of the rig for something when I keyed it and it
started up. I took my hand away and keyed it........nothing. I then keyed it
and while holding the key down and waved my hand over it. It suddenly
started.
So here is the basic recap for those who didn't catch it:
The rig - My basic shunt-fed Hartley for 160M. 3 inch dia. coil of #14
insulated wire wound on PVC pipe. Antenna coil on the same form with 1.5"
coupling. 400pf variable series tuning the ant coil. Grid cap is 250pf and
grid resistor is 12k. Coil is center tapped. 2.5mH choke from B+ to plate.
300pf 2.5kv mica cap coupling plate to coil. Normally run with a 6SN7 at 2.5
watts output.
I spliced a socket for the 811A into the circuit. I then made a cap of about
12pf out of double-sided pc board. It's about .75X.75" square with a lead
soldered to each side. The cap is placed between the grid and plate. I put
420v on the plate and used a 6 amp 6.3v dc supply to light the filament (811A
draws 4 amps). Rig is keyed by pulling the neg side of the filament to B-.
Started up every time I keyed it. Draws about 50ma.
End of test.
I didn't adjust anything in the circuit. The coil tap is fixed so I didn't
want to mess with that and I didn't play with the value of the grid resistor.
The plate to grid cap may not be optimum either. That value just happened to
work. Maybe the thing works differently in a shunt-fed rig than it does in a
series-fed one. I don't happen to have a series fed one to test it in (Bob?)
When I put together the 80 meter rig I'll make all those adjustments and see
what I end up with. Hopefully it will make a usable rig. I won't have time to
fool with it anymore this week so if someone gets a chance to play with idea
please let us know what you find.

Well, I heard 5TVW 599, armchair, and managed a few folks down on 3525.
At 0600 or a little after, I did hear a weak one that probably was a
west of the big muddy type, but too weak to copy. I did run into a fellow
apparently recovering from a stroke (age 65) that was interesting copy.
Kudos to him for hanging in there during recovery.
Alas, Ol' BA Bob folded at 0630, after calling a few rounds more and nil
return.

Well, that is a fair to good indicator. I was not running big power,
maybe 100 watts output from the SRT-14 into a N/S propagating antenna.
I was getting up to 4 amps current into the L network, but dunno how
much was going out the antenna circuit, and how much was looping in the
L network. I was able to work 5TVW on 10 watts, quite well, though, but
not too much above the noise at that power level.

If possible, I prefer 0500Z and 0600Z for any west coast transcons attempts.
I can hang in until 0700Z sometimes, but that is pushing me on weeknites.
On weekends, if there is activity, I will keep a mud pot on and dittle until
0700Z.
I have compared the R-388, the RAL, and the Twinnie Tuber regen against
the kenwoodiewhooie (TS-140S), and aside from the bells and whistles,
everything I can hear on the kenwoodiewhooie, I can hear on any of the
others on 80 and 160M. So, on 80M, almost anything can make a good
usable receiver.
Whomever the weak one was at 0600 or so, 'fess up now, ..... you were
barely heard, but you WERE heard back in NC.

I don't know how you stay awake that lone. I sure couldn't do it.

I heard you last night (Monday) at 0545. You were sending quite slowly and
in QSO with another station who must have been using a TV rock as he was
almost smack in the middle of the TV QRM. It wasn't Sandy. I heard him
earlier at about S7. Your signal sure sounded good. I called you a couple
of times, but was near zero with your frequency so I doubt you would hear
me.

Yup. The HW-16 does quite well, receiver wise, DESPITE the loads of local
QRN. (Gotta make myself one of those DeMaw QRN Squashers).

Also heard someone who said he was in GA.

Eric, we are all pulling for you..... especially me, with a shiny, new-looking
811A just dying to be tried in your 80 meter circuit. I have a Heath HP-23-A
power supply that, I believe, will provide 6.3 VAC for the filament and about
600-700 volts for the plate. I am planning to put it on a lightly stained
piece of Oak that will be polyurethaned after staining. I will probably use
a piece of aluminum for the front plate (unless that runs against the grain
of the Hartley mystic!). Anyhoooo, I am really anxious to put one together.
I've heard that they are "Channel-Masters" and that, in order to maintain
peace among the neighbors and their favorite TV programs, I will have to
operate late, late at night. Let me know if that is your experience with
Hartleys.

Subject: Heath HP-23-A Power Supply
I have a Heath HP-23-A power supply that has an 11 pin tube
socket for an output with the following printing for the pins:
Adj. Bias
AC Common
AC Switch
6V Fil
Gnd
12
NC
+HV
+LV
Fil. common
- -130V
My questions are:
(1) Does anyone know if the 6V filament source will supply the
necessary 4 amperes for a 811A (a potential Hartley rig!)
(2) Does anyone know the voltage and current rating of the +HV?
(3) Does anyone know the voltage and current rating of the +LV?
Thank you for reading this and I would appreciate any info you
may have on the Heath HP-23-A. I do not have a manual on it.

Tom, 29.1 MHz is also a popular AM spot, and all points in between
29.0 and 29.1 MHz.
So, I would recommend doing some listening first or maybe buy 2 or 3
rocks.
