OK Phil - No harm done.  I apologize if I reacted too quickly.

Email is a pretty sterile medium where its hard to see if someone is 
making a friendly tongue-in-cheek comment, or something more serious. it 
is easy to misinterpret the meaning of a posting. I received a number of 
concerned emails about this one which generated my comment.

Probably best in the future to make these emails direct off list when 
commenting between friends :-)

Sorry Eric.  It was meant in fun.  Phil and I have known each other for some
time now.  He got the humor.  I apologize if it did not come across as

Re: [Elecraft] Elecraft: Amplifier for K1

[Ken]

Martin, could you tell me a bit more about how you interfaced the K1 to the
TS520?

I have an old Atlas 210 I would like to use as a power amp with my K1 as you
are using the TS520.  I start writing a  "how to" question and realize I
really don't have all the knowledge to even ask the questions.  I guess the
best thing I can say is - can anyone help me with this project of using the
Atlas 210 as an Amp?  What are the steps involved?   I know there is more to
it than just injecting the K1 signal into the Atlas just past the driver
stage.  I am not trying to save the Atlas for anything else.

Thanks Bob, yes the resistors are metal film or something like that but
definitely not wire wound. I spent a fair time on the air last night on
40/80 with the K1 and 100W from the TS520. It works like a charm. The K1
switches the TS520 T/R relays via a little 2 transistor switching circuit
(looking at the K1 6R line) which grounds the TS520 PTT line. I built the
circuit onto a small piece of vero board which plugs into the 3 pin socket
on the filter board (like the official K2 mod) . A screened cable then
connects the open collector to the PTT pin on the TS520 Mic socket.

I've set the T-R delay to about 500ms so the relays don't switch too much.
Do I need to worry about this? If I set it so that it switches say between
each word will that wear out the relays too quickly, not sure how robust
they are. When operating the K1 barefoot I use a T-R delay of 50ms.

Thanks

Hi Martin,

Got that fine.

You have got the best of what is possible using the TS520 with the way you
have done the mod.

Just a point make sure you do not use 2 x100 ohm  wire wound resistors for
the dummy load. They must be carbon otherwise odd  effects can occur due to
inductance. You may be well aware of this effect, but I  am pointing it out
in any case as 2.5W is one of the standard dissapation values  for wire
wound resistors!

Bob, G3VVT

[Elecraft] Elecraft: Amplifier for K1

[Martin . Evans]

Hi folks, I have a TS520S. The low level circuitry is faulty but the PA and
tank circuits are OK. My main rig is the K1 but it would be nice to be able
to run QRO on occasions. So to get QRO on the cheap could I use the PA on
the TS520 as an amp for the K1? My antennas are all resonant so matching to
the TS520 is no probs. I guess I would loose QSK and would need a relay to
bypass the 520 in rx mode. Not sure what sort of signal level would be
required at the grid of the 1st 6146. One thought is to operate the K1 into
a dummy load with a resistor divider tap off to feed the amp. Don't really
want to modify the K1. Also is K1 OK being operated in close proximity to
100W tank circuits. There's plenty of metal around it.

This is all off the top of my head and I have no experience of RF power
amps. Am I flogging a dead horse here or should I just build a linear?
Can't afford a K2 hi.
