That's a brilliant suggestion. I wish you had posted it before I flamed my

BTW Elecraft (The Best Radio Company in the World) sent me the replacement
part for free. Pretty impressive as it was obviously my fault.

I am considering getting the 144 transverter. I am curious if there any
other benefits of installing the X60XV apart from not having to switch

How about adding an extra pre-drive stage with automatic

That's how some of the other amps seem to do it. If you

Mike,
I'm sure Don and Ken are steering you right. Visual inspection of the
thermistor board may not be enough. I had a problem there myself, signed off
on it as good several times and went looking elsewhere for the problem.
Finnally, after quit a bit of disassembly, I reflowed what
A power gain of x40 is very high for a mass produced RF ham amplifier (about
17db). I believe an FCC rule limits it to 15 or 16db for US marketability, due
to CB issues in part.
Many non-US amateur amp developers work around this by using power swamping
resistors in the input circuits, of the

You should never have to increase the AGC Threshold voltage above 3.8 volts.
In some cases you will want to lower it a bit, but not raise it. The proper
adjustment occurs near the pot maximum.
If I understand you correctly, all is well.

Dave,
You will gain low level input to the XV144, be able to utilize separate
transmit and receive paths between the XV144 and the K2, and yes. if you
use the K2 for HF, there is no need to change the HF antenna when using the
transverter.

Yes, the N-Gen does not like to see transmitted power at its output!
Check to see if MiniCircuits has any European sources.
Your least cost alternative may be to send a note to
mailto:[EMAIL PROTECTED] and ask for a replacement.
Dans Small Parts has a suitable substitute (INA-10386)
Maybe the lesson here is: If you're using the ngen, stock a few
spares of the MMIC ??

Mark,
I don't think so! Putting the K2 into CW TEST before attaching the N-Gen is
a wise thing to do.
Since I do use mine more frequently than most (3 or more times a week on a
regular basis), I do keep several spares on hand for whenever I lapse into
forgetfulness.

Hello Elecrafters!
I have just finished building my new KAT100 and the XG2 . They both work
very well indeed.
I am using a K2/100 (serial 5310) with a regular power supply off 220 volts
and, occasionally, in the middle of my CW transmissions, the Lo Batt
message pops up on the display (beep
If the input DC voltage to the K2 is too low, it will say LO BATT (for battery
or external supply). I got the same message when I was using a power supply
that was putting out too little voltage. The manual tells you the acceptable
range, but your power supply should not drop to 10 volts.
Yep, been there, got the tee-shirt! A sniff of RF zaps the MMIC and creates
the Homer effect (DOH!).
Murphy's law states that if it can possibly go wrong, it will do so at the most
inconvenient moment. I seem to prove Murphy's law most days HI!

Thanks to those that sacrificed their NGEN, it's helpful for me to
read that, as I'm building an XG2 at the moment and it will help me
remember to go into TEST mode before connecting it ;)

That says that you have a problem with either the thermistor board (your
previous email indicted thatyou did not), or in the path from the U6 pin 1
output to the varistors. Check the soldering on R19 and those components
that are near it (check the schematic to find the other connected

Guess I better check my setup. I definitely was using an external supply, got
the LO BATT message, and verified that my power supply was way under requried
voltage level. I guess from your note that I may have the switch in the wrong
position.
