Hello list-readers!
Just another reminder of the nightly BA/Glowbug qso party. Bob, NA4G was on
last night with an excellent signal from his BC-375 (and of course Big
Bertha) and I was on with the trusty TCS. We meet around 0300Z on 1802.5 and
lately have been QSY to 3702.5 at 0400Z for the antenna-impaired. 
Please join us as often as you can. Speed is no issue with us. Heck, we will
even work you on a non-hollowstate  rig ... just use a key/keyer of some
sort and jump right in.

See  you on the ether,
ZUT! de Conard, ws4s

P.S. If you haven't seen the photos of Bob's creations, feel free to check
out my ftp server at triode.cc.tntech.edu. There are some other interesting
files on there too.

I heard NA4G last week on 1802.5  - called him a few times, but my 5w
wasn't making it. He was about 579 here. I'll try and blow you away on
80m tonight. I can start at 5w and if that doesn't work I'll put the
3-1000 amp on...

Lo and behold, whilst sorting through my motly assortment of tubes, 
toward an semblance of organization into the Xmas tree ornament box my 
wife presented to me (and I mean PRESENTED, not gave me a present, hint 
hint say no more), I came across 2 6L6 tubes. Didn't know I had 'em. 
Tested up fine in the tube tester.

So, now that I don't have to wait at all to find some at the flea market 
or surplus emporium, anyone want to throw out their fave 6L6 xmtter 
circuit to me. I've got a few  here, from 73 (6L6 Special), CQ (Ingram), 
and some photocopies of 1938-39 Fred Sutter 'QSL' projects in QST.

There is a wide variety of complexities amongst them - ranging from 
'really, that looks too simple' to very involved (the 2nd place winner in 
an old 73 'home brew' contest).

I am lucky in that I have a couple old Heath power supplies on hand, for 
HW-101 and HW-12/Cheyenne sort of rigs, that can give me the 300 or 450 
volts for the plate, as well as filament voltage of course. So I don't 
have scrounge up transformers, power chokes, rectifiers, and electrolytics 
for a p.s.

Your input is welcome - looks like winter is settled in here for awhile; 
record cold temperatures around here now and into the weekend, so I think 
Feb. is a nice month to brew up a 6L6 transmitter. 

Bands; 80 or 40 for now; or 30 m. for the summer (tubes in summer! hmm, 
perhaps..); no fundemental xtals here for 160m. currently, but there is 
for 40 and 80. None for 30m either come to think of it. Could have some 
fun and use the VF-1 vfo and forget about xtals and just build it for 
whatever band.

Thanks. So hard to choose from the variety of articles on a 6L6 xmttr, so 
I'd like to go the right way, but not cop out and go too easy or spend 
too much time going unnecessarily overboard in complexity.
Most of the big ham mags are in the library here, so if its in QST, 73, 
CQ or HamRadio I can probably look it up. Thanks for any suggestions.

72,

Brien

Brien,

Are you looking to build a single-tube circuit or a MOPA?  When I 
-finally- get some time I'm going to build a "detente special" (JAN 
6AG7 and Sovtek 6L6 (or maybe two?)).  Lots of circuits for this lineup 
in handbooks -- I'm sure I could dig up a couple and send them to you.  
They don't seem to vary much except in the output circuit (tank or pi 
network).  All the ones I've looked at use simple untuned coupling 
between tubes.

Changing the subject a bit, does anybody have a source of 1 and 2.5 mH 
chokes at less than AES prices?

73,
Mike, KK6GM
