The grid driven amp was abandoned in amateur service due to drive power,
stability, complexity and cost reasons, in spite of what manufacturers and
salesmen of tetrodes would have us believe!
Amplifiers using grid driven tetrodes cost more to build, are harder to
build, and are more critical to tune and operate than a GG triode PA. The
ONLY thing you save is tube cost. In my mind, saving a few hundred bucks on
the tube isn't worth the risk of not getting a replacement if anything goes
wrong with the sole manufacturing plant in Russia. If it was a pin for pin US
equivalent, that'd be one thing. But a unique tube with a unique socket and
all those complicated voltages to re-design? No way. Not for me.

Actually the grounded grid amp has the same advantage. Tetrode's like the
Svetlana are a good stable design, but large glass tubes like the 4-1000 are
terrible! The leads are just too long.

I have used the same system with tubes like the 4CX5000 and 10,000, but only
when many kilowatts are needed with low drive. If the power gain requirements
are moderate (perhaps under 50 times), grounded grid tubes are a much better
choice.
Why add complicated screen and bias systems with protection circuits, and
make the amp more sensitive to tuning, just to save a few bucks in tube
cost? If I had a five watt exciter I'd used grid driven, but not with a 100
watts or more. If I was hell-bent on a low gain tetrode I'd at least use the
Collins 30S1 circuit, it offers far better performance than a resistor
swamped grid.

I get shipped to me at least $40,000 worth of computer gear each week. My
only gripe is when the guy is more than 5 minutes late! I never get
dammaged goods and the stuff is there when they say it's going to be here.
And you can use credit card and check and cash. And you can track the
packages via your own PC. And if you call the customer service # you will
get someone on the phone right away.
Bottom line you get what you pay for.

Subject: RFI info?
Gentlemen,
I've been recieving some kind of rather wideband interference on
several bands, most noticeable on 40, but I also hear it on 80, and just
barely on 20, and usually below .025 or so. Sometimes going above 025 is
like throwing a switch, it's completely gone. The peak, and width, and
therefore the band segment it covers, moves up and down at different times.
I can't say I see a pattern to that. I have been looking for causes here,
but the other night a particularly strong blast caused another local to
comment on the cluster, so now I suspect it's not something at my station,
unless that occurence was something entirely different. I've found a 720kc
AM BC stn near here whose 3rd harmonic is 40 over, and 5th is 20 over (with
the rig on AM). Am I getting mixing products, or is anybody else hearing
this garbage? If nobody else is hearing it, how do I go about tracking it
down? I don't pick it up on a portable SW rx with the built in extendable
antenna. It's not coming from my house, I tried turning off all the breakers
except the shack. When it's there, it's there with or without the computer
on. Did I mention that it comes and goes? Sometimes I don't have it at all.
Suggestions?
Thanks,
Steve

>Dave K4JRB
Dave, one minor point on the old W0SYK designs (there were two:
The Bib Bomb 73 Magazine May 1965 and The Mini-Bomb
73 Magazine May 1969) which were popular in the St. Louis
area in the 60s and 70s. Both designs DID use bifilar chokes in
the cathodes, which is required for the isolation of RF from the
filament transformer. What was eliminated was the matching
network normally required to match the desired 50 ohm input
to the cathode, which is in the neighborhood of 105 ohms for
a single 4-1000. By paralleling two tubes this was reduced to
approximately 52 ohms which made a nice match for the
exciter. But there is a penalty for eliminating this matching
network. The RF ground for the tubes is now returned through
the exciter, making cable length and tuning of the exciter an issue.
The results are an increase in IMD and, sometimes, in unstable
tuning. It is a much better design to include a return path for
the cathode within the amplifier. Doesn't take much of
a network, either L or pi will do and the Q can be as low as
2, so there should not be an issue of tuning the input. Lower
IMD will result, making for happier neighbors on the crowded
bands during contests and it will be somewhat easier to drive
the amplifier.
----additional notes on grounded grid operation----
The 4-1000 is a good tube in grounded grid but just doesn't
have the gain of a tube designed for gg service. But stability
can be an issue on the higher HF bands due to the normal
resonant frequency of the screen grid and its phase shift
that results in a tendency for positive feedback near the
bottom end of the FM broadcast band. This can be reduced
by adding a little inductance in the ground lead of the screen,
thereby reducing its frequency a bit and producing a phase
shift that tends to reduce the tendency for oscillation.
Just grounding both the grid and screen in the 4-400, 4-1000
series tubes resulted in the grid hogging the current and limiting
the tubes capabilities. A technique to provide better division
of current between the grid and screen in grounded grid is to
tap the grid connection down on the filament choke. This results
in some RF being applied to the grid as well as the cathode and
the tube will have a better balance between grid and screen
currents. The penalty is that the tube takes about 30% more
drive for the same output. Grounded grid operation of the 4-400
and 4-1000 was so popular that Eimac designed the 3-400 (later
the 3-500) and the 3-1000 (and now the 3CX1200) specifically
for use in grounded grid. These tubes are better suited for gg
operation, but it is hard to beat cheap, surplus 4-1000s for
performance and cost, even if a much higher plate voltage
is required to got reasonable gain from the 4-1000. Anything
less than 4-4.5 KV will provide poor gain and run the risk of
damage to the tube from excessive grid and screen currents.

This is a complex problem, though. If we change our existing contests to
more intricate exchanges, we have to throw the existing records out the
window. That's bad. I think Bruce's proposal has merit since it allows an
existing meaningless exchange to be replaced with something meaningful.

The difference here is that currently, copying 59(9) has no intrinsic
value. Since everyone sends 59, you can't tell if you are loud or weak, or
what conditions are like at the other end.
However, sending a check value -- even one that could be computed from
other exchange information -- has intrinsic value. Say you weren't sure you
got his call right, but you KNOW you copied the check correctly. Your
computer tells you that the check is correct. Voila, you don't have to call
for a lengthy repeat of a callsign, because you guessed right.
In another case, you thought you got everything right, but your computer
tells you you have a bad check, so you ask for the exchange again, and end
up correcting your mistake. (Hmm, so that wasn't N4BO after all, it was
NV6O)

If you do this, be prepared to throw all the records out the window. You'll
have a completely different type of contest. Rates will plummet, errors
will go up, scores will go down.
This is why I like Bruce's suggestion. It doesn't really involve sending
much more information (two digits), and it convey's something meaningful to
each operator.
My only suggestion is that we change the values to something more easily
computable. Don't use ASCII Hex, just a simple formula people can calculate
without computers (not everyone has computers, you know).

THESE SCORES ARE NOT OFFICIAL!!! I CANNOT ACCEPT ANY LOGS!!!!!
PLEASE SEND ALL YOUR LOGS TO THE ADDRESS IN CQ MAGAZINE!!
The address for the 3830 reflector is 3830 at akorn.net!! Maybe someone can
post on here how to subscibe to it. I am not sure and do not want to put
out any bad information.
Also as I stated in my post before the contest, I cannot do attached
files. You need to send it in the form of email. Also please state your
full class on it, not just Single OP. If you do you go into the unlimited
class.
Before everyone starts flaming me about where there scores are, I would
like to explain. I received a list off 3830 from WZ1R. It only gave me
classes for people as SO. I know some should be unlimited. If you would
just drop me a note I will be glad to move them.

Message-ID: <199604051651.IAA26368 at julie.teleport.com>
Thanks to all who offered opinions and advice! I wanted to e-publish
a quick update to those who are curious about the outcome...
I had no luck getting permission to walk the property and find
the problem with the fence. The neighbor, although willing to
listen to my woes, was not willing to have me on his property. Why
this is so is up to anyone's hunch. I have a few of them I won't
go into...
So, I ended up writing a letter to the county Emergency Services
department with a cc: to the power company, ARRL, and the neighbor.
Basically I informed Emergency Services 'about the progress in
solving the interference' and that the 'neighbor had genuine
concern about the noise'...and that I would soon be back in full
service to the county in an emergency capacity.
I sent the letter(s) off Monday. Bingo! As of Tuesday afternoon, no
more interference from the electric fence. Apparently the neighbor
was getting a little more publicity than he wanted. :)
I have my fingers crossed that the interference won't return. It
could be the neighbor just turned it off, which is fine by me.
Thanks again,
John

Hi John,
I work for the local power company. One of my many "hats" gets me involved
in training line crews and technicians how to locate and resolve power line
interference. You are not alone with this type of problem as you likely
found out by return email. I watched some of the replies, some humorous,
some not so. I was too busy to give you advice at the time.
I too had an electric fence problem with a neighbor that was really a
problem on 80 and 160. Fortunately he is far enough away that I have never
caused any tvi or other problems. We don't share a property line...this
always complicates things.
While scoping out the source from the road with my sniffing equipment (Radar
Engineers, good stuff!) I found his fence was broken and the ends were
laying on the ground. I approached him about the noise problem and told him
that his prize horses were likely to get out and mix with traffic if it
didn't get repaired. I also pointed out how this break was causing rfi for
me and likely others. He mentioned that he was seeing pulsing interference
on his tv. What luck! I offered to repair the fence for him, but he said he
would look into it. That evening, the noise went away. Just in time for WPX.
I also had to get a line crew to go to an adjacent residence and replace an
insulator on the cross arm which was also being a real pain. Where I live,
the ambient noise level is quite low...usually. I try to keep on top of
noise sources here and have been successful to date.
Others are not quite as well equipped as I am. For them I suggest they
contact their local power company and seek out the department (rfi swat
team) that does this type of troubleshooting and repair. Hey, you pay for
that service in your bill every month, might as well get your money's worth!
I think your letter writing was a very good approach given the state of
relations with your good neighbor. My guess is there is something on his
property that he would rather the authorities not see......were it late
summer I would suspect something growing there. There are all kinds of
possibilities. HI
Good for you at any rate!
