I was on after 10pm, and heard the 5landers but could not raise anyone.
Little else was heard. Strange bands probably.

Anyone planning on building an ECO? If so, what are you planning on using for
a tube? I already have Hartleys for 160M and 80M so thought I'd build a
version of the Barracks Bag VFO on a big 'ol breadboard. I've got 6L6's,
KT88's, 6550's, 807's, etc but thought maybe a bigger tube might be fun. Not
looking for a lot of power. Just a big tube barely idling. Any
recommendations?

Subject: Hartleys...
I think I may have found THE power-supply for small Hartleys: it is the
H-P 712B Regulated Power-supply. All tubes except for one small selenium
rectifier. Real BA for sure.
Puts out 0 to +500 VDC at up to 200 ma, -300 vdc regulated bias at up to
50 ma, 0 to -150 VDC variable bias at 5 ma, 6.3 VAC CT at 10 amps.
Both regulated sources hold within 50 millivolts, no-load to full-load,
and less than 100 millivolts for 10 % line voltage variation.
The only fly in the ointment is that it weighs 85 pounds (rack-mount), is
10 1/2 inches high, 19 inches wide, and 13 1/4 inches deep.
Probably bigger than Grandma Hartley.
Well, at least I got it for nothing. Sure wish I could find 3 more...

Heard N4QY talking with NA4G and WA9WFA, but didn't hear EITHER NA4G OR
WA9WFA. N4QY said he was using a Heath SB something. Wonder what he was
using for an antenna? Tried to BK, but no soap.
Shunted my 3579R545 rock with a variable cap tonight. Can pull it nearly 2
kHz before it gets hard to start. Decided that was kind of redundant so
used the HG-10B VFO instead.
Rained hard here today. Then blew hard. Hope that portends a change in

I have planned to use the EL34 (6CA7). The supressor grid is not internally
connected to the cathode in these which I think is an advantage in this
circuit. It's also almost pin compatible with 6L6, 6550, KT88 et al.

Great idea Sandy. How's this for an additional safeguard.
You could let the core float above ground, by insulating it from the
chassis it is mounted to. Just mount it on short standoffs or use the
phenolic shoulder washers in the holes so that the screws don't
contact the chassis.
Jus' an idear!

Well, it's been done; a well-known emergency "fix" for a BC
transmitter with a winding-to-core short in a choke (or whatever) was to
stand the subject iron on a great many old-style short Coke bottles!
But it's not a good long-term fix, as you end up with a big object
usually assumed to be grounded at a high potential instead. In Sandy's
case, the "floated" *could* end up hot, and no way to be sure--an
invitation to trouble.
A safer trick can be found in the old "Radio" Handbook: put the chokes
in the B- side of the supply! It works just as well as having them in the
B+, though you often have to change the grounding around to avoid shorting
the choke. That way, the core sits at a *defined* potential, and the
windings are at most only above that potential by the drop across 'em.
However, it can be awkward to implement in a commercial device. Simply
repairing the choke, using plenty of good insulation where it will do most
good, is perfectly acceptable. Done as Sandy describes, it should last at
least as long as the original design did!

The ideal way to go, really.

The oscillator can be keyed differentially or by slow differential.
Differentially, it requires sequencing the contacts on one or two
relays or providing some other electronic lag system. Slow differential
only requires that the oscillator be turned on at the first keydown and
left on for sufficien time to remain on between words --- in modern parlance
that is called ``semi-breakin'' Yech! Once you have used full breakin it
is a step down to use manual or semi-breakin at anything other than liesure
speeds. QSK becomes fluid and conversational rather than round by round.
Even OT Hartleys will QSK with some fiddlin' with a regen set. All hands
are invited to try it sometime.
There is a cheapskates approach to differential keying, and QSK that
works very well with a little patience, on low power sets. It requires
a 3PDT relay or two SPDT relays. The trick is to sequence the relays
so that the antenna is removed from the receiver and grounded at the
receiver or shunted to the transmitter first, then the next contact
closes for the oscillator and the third contact closes for the amplifier.
It works very well at normal hand keying speeds using ordinary relays.
It requires fast reed relays at QRQ speeds. No fancy differential timing
circuits are required, just a carefully adjusted relay. Using two
relays, the antenna is fired on the first relay, with a smallc capacitor
to store a few milliseconds of charge and the second relay does the
differential keying. Carefully bend or otherwise adjust the contacts
to sequence properly as the relay actuates.
In the olden days, when real antenna relays existed, you could buy a good
one from Leach and other manufacturers that would do this very well.
All such relays had adjustable locking contact screws for finely setting
the timing of the various contacts.
The Navy used such relays in most of their aircraft and many ground sets
in WWII, but dropped QSK by the time Korea came about. Things like
the TBW, TCS, and similar rigs have fairly good QSK relays with sufficient
contacts to do good differential keying, too. The bigger ones are only good
up to about 20 wpm, but the smaller ones will get to 30wpm before falling
apart.
The Army used such relays in things like the BC-375 where effective
QSK could be done. That bloody thing will QSK easily at 35wpm when
properly adjusted. Alas, with some 7 DPDT contacts to adjust, it is
a bear, and requires special tooling and meters to set properly.
The usual unadjusted random BC-375's will QSK to about 25 wpm easily.
Alas, it is a lot art using relays, anymore, mostly, but a few
articles appear in the ham rags occasionally based upon reed designs.
There is nothing fancy to differentially keyed QSK, just a little
forethought and a contact adjusting tool. Electronic forms are better,
perhaps, but more complicated. Relays do fine with some fiddlin', and
are more than satisfactory for glowbuggin' at hand keying speeds.
