I have had excellent results from this stuff too! DO OBSERVE the
warning
about it removing lettering! 95% of the time there is no problem. I try and
followup with plain water/paper toweling to remove the traces of the
cleaner as it is caustic and I don't like to leave it behind. It has worked
VERY
excellently for me. DO NOT use this on old silk screened paint lettering on
glass or plastic, as the lettering will be damaged or disappear! I use a mild
solution of dishwishing detergent for this!

Folks,
In the "Communications Receiver" column of the Oldtimers Bulletin, just received,
the product "Birchwood Casey Brass Cartridge Case Cleaner" is recommended as a general
purpose cleaner for all sorts of metallic radio parts and other durable parts, such
as Bakelite knobs, etc. The stuff is mixed as directed and may be stored. Caution is
needed as it is capable of actually corroding thin platings, but is still recommended
as an excellent cleaner. The writeup suggests that complex components such as air
variables be dis-assembled before cleaning, and in stubborn cases, 0000 steel wool
used to scrub the parts, being careful, of course, to remove any traces of the wool
after cleanup. Through rinsing with clear water is a *must*. This stuff is available
at any gun type shop.

Subject: Re: QSK with Straight Key
Enjoying reading the mail - thanks folks! Re: the key with two sets of
offset MAKE contacts for QSK - I have an old RAF knee key with separate make
and break contacts - I'm thinking of rigging it for QSK so that the break
lifts the cathode return of the amplifier stages of my RX (obviously this
can only address RX "desense"; I'll still need two antennas and/or TR
switch) - don't suggest that anybody else try this unless they're REAL
careful and dry-handed with the voltages!
I believe use of the break contacts for QSK relay control and lead "lifting"
(or removing a bypass on a shunt resistor, etc.) was a common technique in
the past.
Well, enough jawboning - need to get working on my TX so that I can proudly
'chew on the air!

Subject: 80M/160M Funzies --- da bands are hot they are
I had the sets on 160M last night at the usual QRG 1802R500 +- whatever.
The band is quite good, these days. 80M is magnificent. I will park
Big Bertha Radiomarine on 1802R500 for the next few days with Grandma
Hartley et al on 3579R000 +- whatever. Hope to work a few of you.
I hear lots of stations on both bands, now......

Subject: Hartley ECO Keying
Bob,
Just a quick question.........
Just finished a Hartley ECO using a 6L6, 6550, etc. Runs straight
through....80M osc and plate tuned to 80. Modified for pi-net output. I'm
keying it in the cathode to coil-tap line. Is that the best place? What would
you suggest?
Tnx and 73 Eric KA1YRV

Subject: Grid Leak Advise
I recently obtained a copy of Practical Radio Telegraphy by Nilson and
Hornung, McGraw-Hill, 1928. I was reading it last night and felt I had to
share the following paragraph on troubleshooting, particularly since this
is Hartley month.
"Burned-out Grid Leak.-The usual resistance of grid leaks used in this type
of transmitter is in the vicinity of 5,000 ohms and should the original
burn out it may be replaced by an approximately equal resistance. Where
this is impossible, a rubber hose about 10 in. long, filled with salt water
and plugged at both ends with a cork, with wires extending from each of
these ends into the water, may be used with satisfaction."
I guess that if the corks aren't sealed well, one would really have a grid
LEAK! Is anyone game to try it?

Priceless! Were either of the authors ex-navy types ?

Subject: 3579 QRG Wednesday night...
Heard N4QY in QSO with a WB9. Also heard W5II(?) calling Sandy W5TVW, but
didn't hear Sandy. While N4QY was busy, I heard WA5UEK calling CQ a bit
higher in frequency. Tried calling him and he came back to me! He was
pretty weak, but peaked at 569. He said he was in Plano, Texas and was
running 90 watts to a dipole. My HW-16 was chirping away happily. Don't
think WA5UEK ever sent his name. Although he had real trouble copying me,
he did get my name and QTH. Good for him! All this was at 0330 to 0400.
Maybe I can hear Bob and Sandy someday yet.
Sure wish more GB/BA crowd would try 7050.
I sure like the BA/GB crowd. Good people.
