Hi From Freezin' "Bonnie Scotland"...
I am looking to buy one of the above enclosures (think most are from the
late
60's or 70's) for an up-and-coming project...
Also would be interested in the inside "chassis" part...
If anyone has one of these lying around surplus to their needs please drop

Good Evening,
That was a good time. I am feeling the effects of a woodstove too
warm, a very good dinner, and not enough sleep from the night before. By
the time I was finishing up the roll call I could not get AB9V sent
correctly. Sorry Mike! But as I was writing up the lists and fil

last post.
Saved this time by Ron - thank you.

Hi, Jamie:
First, troubleshooting, voltage tables, etc., are in the Owner's Manual.
Their location is called out in the assembly manual on page 53: Final Test
and Alignment, in case you run into a problem like this.
Be sure you incorporated Errata C-4 into the Owner's Manual. It includes an

Jamie,
If you are dealing with an XV50, you should not have an R39 installed. There
is no quiescent Current Adjustment for the XV50 - see the statement right
under the 'Part V - ...' title.

I believe the Elecraft rule still is: If you need new firmware when ordering
an additional OPTION (not upgrade or mod), then the firmware will be
provided at no extra cost.
Many (probably most) of those ordering KPA100s already have firmware
adequate to support it (Firmware 2.02 or later is

That is a result you would observe if the K2 were locked in transmit. Check
to see if you have a problem with the PTT input or the paddle DOT input
first. If you don't find anything obvious, let us know and we can likely
provide some other checks (but you will have to do some measurements
Ron and all,
Since you have not used the KPA100 mounted externally Ron, you likely did
not know - when the KPA100 is used externally to the K2, the cable to the

microprocessor and those signals are not included in the KIO2 to KPA10
Hey Friends,
I'm wondering if there's a hidden switch somewhere that would allow
the KDSP2 to power-on in bypass (or off) mode? The manual says:
"On power up, the KDSP2 will default to the first filter for each
mode. It will retain the current filter for each mode until power is
again cycled."
The latter, John.

You do *not* need to remove anything from your existing K2 cover. The KIO2,
ATU and the battery (if installed) can stay right there. What Don was saying
is that you get a NEW top cover in which the KPA100 is built and it mounts
in place of the current top cover. So you can change from a K2/100 to a

That's an excellent way to go, I did this for a friend and he loves it.
Only one thing you have to remember, when you use it as a QRO station it
automatically shuts off and bypasses the internal tuner, when you unplug
everything and go portable with it you must remember to turn the tuner back
on in

Don, John & Gregg,
Thanks for taking the time to respond. I think I will put the new stuff in
a EC2 enclosure and leave the QRP K2 alone - particularily since I already
have the KIO2 installed. Seems that might eliminate some of the heating

Tom,
You existing KAT2 (and everything else in the QRP K2 top cover) is removed
and the KPA100 installs in place of it.
There is another option available to you - if you want to retain the QRP K2
for portable use, then mount the KAT100-2 and the KPA100 together in an
external EC2 enclosure. That

2. Does my existing ATU stay in the circuit?

Trevor,
If your R19 and R20 resistors have a reddish/brown body, you can leave them
in place - those are the good ones. The potentially bad ones are the light
blue bodied resistors, and not all of those are inductive, but it is easier
to just call for replacing them than to explain which ones mig
Dave,
That reference to a closed loop ALC with the K60XV applies only to the low
power transverter outputs of the K60XV. It will not modify the ALC action
for the normal HF outputs.
Your lack of power control on 40 meter SSB is quite another matter. It
could possibly be an oscillation occurring

Don,
Zero beating does not involve hearing down to zero cycles. It is matching
two tones, whatever their frequency, until; the beating phenomenon, which is
not a sound comprised of frequencies lower than the audio passband of the
receiver or below the lower limit of human hearing, stops. As you
