I am looking for the specifications, ratings and pin diagrams for a
Russian-manufactured tube. The tube is a GU-74, a seven-pin external-anode
metal-ceramic high-power tube suitable for use at HF. I intend to use it
in grounded-grid as a linear amplifier.
The full markings on the tube read as follows, transliterated from Cyrillic
charcters: GU-74B8707 OTK 18
Can anyone help?
Thanks,

Equipment Description:
RIG: FT-990 & 486DX2-66 MHz running CT. ANT: My CC&R's prohibit external
antennas, so I have an indoor 20m, 15m, and 10m fan dipole, stuck to the
attic rafters in my townhouse with push pins (green for 20m, blue for 15m,
yellow for 10m) and a nearly invisible 40m delta loop in the eucalyptus
over the garden wall.
Condo's and Contesting don't mix.
Perhaps I am jumping to conclusions, but there seemed to be a few stations
on 40m late in the contest flagrantly violating the QSY rule. Is there any
means of enforcing this, or is it strictly on the honor system?

One of the better ones I heard during the /125 thing was

the last two please.
speaking of GAS (agn.) I was reading though NCJ last night
July/August 1990 and noticed a "for sale" home and one of the
features was 3-PHASE POWER. Maybe 3-phase power isn't as uncommon
as I thought. (pg.23) Now why would a 2200 sq.ft. home need 3-phase?

It may be hard to appreciate, but multipliers in the Sprint are not purely
serendipidous. It is somewhat like poker. Beginners may think they loose
because they are unlucky at cards. Skilled players make decisions based on
experience and probable outcomes. In the long run, these count, and they
win.
To first order, in the Sprint - knowing who is active, and their QTHs, and
what they sound like, allows you to identify stations that are multipliers.
Then, there can be skill involved in getting them, particularly if they
can't stay on the frequency, or you get beat out while calling them.
Second, there are overall operating strategies that probabilistically
maximize your multipliers. They don't work every time, but over the long
run, they produce results.
These apply to North America, not VK5, where you celebrate every time
someone comes back to you.
It's almost time to go back to California. Oh boy, maybe they'll still have
24 hour a day coverage of the O. J. Simpson trial on TV. I'm tired of all
these kangaroos.

For the record, K7GM/4, low power, CW Sprint, 237 x 41 = 9717
(20=80Q, 40=95Q, 80=62Q). Haven't figured the N6XI excuse multiplier yet.
Condix seemed long on all bands (NJ and FLA mults were touch and go).
South and west was the place to be (on the west coast, SFO and south were
loud, north of that was puny weak).
Comments have been made concerning the use of multipliers in the
Sprint. Although there is some amount of serindipity associated with
your multiplier total, there are also techniques you can use to increase
your odds. Your multiplier total is not entirely random. At the risk of
giving away too many trade secrets consider the following:
1 - Some bands tend to be more multiplier-rich than others at differing
times. When you first consider going to 40, you will obviously pick up
a number of multipliers since your skip zone will be different. Even more
importantly, however, is the point when you stop running them on 20 and
start running them on 40. At some time the Q rates on 20 or 40 will start
to be similar. You have to weigh, however, going to 40 and have a good
chance of picking up some closer-in mults with, maybe, a bit lower Q rate
against staying on 20 and keeping the rate a bit higher. You ask yourself
whether you think 40 will go long before you "get there" versus whether
you will lose Qs on 20 that you will not be able to make up.
2 - There are some techniques you can use to help your multiplier
total: If you hear a needed mult that will be moving, go up (or down, if
you prefer) and call a CQ (or call the station); go back to 20 and 40
"late" to pick up a few stragglers, many of which turn out to be mults;
have a second receiver on the low end of the band looking for Carribean
or Canadian mults.
3 - When you hear a mult you didn't get, remember the call and use
that knowledge when making band-change decisions and when tuning the band.
In the final analysis, the inclusion of multipliers adds another
element to Sprint scores. You need to think of other things besides
just rate. You have to position yourself to increase your multiplier.
It may not always be sucessfull (EVERY time you go to 40 late you will
not pick up a multiplier, but OFTEN you will). I, for one, don't want
to see us get to the point where the only question we ask ourselves in
the contest is where can I get the best rate.

Oh, yes, you can...one of life's true frustrations. "Which way is he

The Better Ed than Dead team was pretty small this time around; K7SS,
N0AX, WA7UVJ, KR7G, and K7HBN. No certificates for us! 40 seemed mighty
good, having a beam helps, even if it is sitting on the chimney! Worked
KB8N/WVa QRP for another QRP 5BWAS counter on 40...I'm a masochist.
Missed Neb and Ks, though, and where was WD0T for South Dakoty? Had fun,
will in the next one, too!

I think the answer is that they aren't very good at directing efficient nets
or passing traffic quickly. I've seen a slow, but steady degradation of net
operating technique in my 28 years on the air. We are now in the era of "This

Agreed. It was a pleasure to work the guys who could spit out "fiftynine dxfr"
instead of "five and nine, ah, do you have all my information?". And it must
be some unwritten law that I'm not privy to that says you get extra points for
keeping your call sign secret for at least 10 minutes.

Charlotte, KQ1F and I are planning to operate the CQ WW CW from
Dominica, J7 (not to be confused with the Dominican Republic).
We are renting a two bedroom cottage on the north side of the
island. The owner is ham-friendly and says that the gardener
will help put up antennas.
I'm looking for another operator or two for a multi-single.
Non-smoking preferred, and some knowledge of the code would
be useful. First-time DXpeditioner is OK, as is ham plus
spouse. There are additional cottages on the property if
a couple hams and spouses want to go.
If you are interested send mail to young at young.enet.dec.com,
or better yet call me at home (508)562-5819 or work (508)486-6597.
