Jeff,
I also measure 4.89vdc at these pins so that is OK. I haven't looked to see
why yet.
Have you built the RF probe and traced the transmitter signals as outlined
starting on page 12 of Appendix E of the owner's manual? If so what were
your findings?

I have for sale a (QRP) K2, SN 2676 in excellent condition. Includes:
KSB2 SSB Adapter
K160RX 160M and Receive Antenna Adapter
KIO2 RS-232 Interface (home-brew)
Finger Dimple
The K2 is up to date with the latest 2.04 firmware and all modifications to
bring it to NEW specifications. Looks,
IMO, a mag-light is great for inspecting one's work, but if one intends to use
the mag-light while soldering, the need to be 8 inches or less away from the
work will interfere with most soldering irons...That is when a magnifier worn
on the head, or clip-ons, are better...

Hi Everybody.
Perhaps it was too cold for your to FYBO, or after
coming inside and warming up you still have the itch
to operate, or perhaps if you couldn't get enough of
the outdoor experience and want to do it again for the
bonus points.
Here's your chance with the QRP-ARCI Fireside Sprint

In terms of freedom of movement and field of vision, I like the drug
store reading glasses better than the big black visor type magnifiers.
Depending on your age, a diopter rating of +1 to +2 is good for most
soldering, and +3 for small SMD. They're cheap and readily available.

Jeff,
If the VFO moves and you can receive, then the PLL is working - that is not
your problem area.
Jave you assembled that RF Probe yet? That is the key to doing your
analysis. Do the checks as outlined in the Transmit Signal Tracing section
of Appendix E in the manual.

This is my first posting so fingers crossed that I get

Trevor,
You have the correct area to look for the problem - Q11, U3 and the
associated components.
Check the soldering carefully, be certain Q11 is oriented properly, and
check all the components that connect to Q11 and U3A (those components shown
on the schematic).

Hello all,
Considering the purchase of a KX1.
With the sunspot cycle soon to be on the upswing, I'm wondering if Elecraft has
any plans to offer 10 and 15 meter options for the KX1.
This would certainly add to the versatility of the KX1.

Well gang the LP-100 is all done and calibrated. Kit arrived around 2:30pm
on Friday, went straight to work on it. Finished build and initial
check-out around 10pm (include Dinner, Potty, and libation breaks). This
morning I spent an hour doing the calibration and final assembly. It's all
up
I have a weird problem. I'm running my K2 about 10 watts into an amplifier.
When I am in a ragchew QSO on CW, the K2 stops keying after about 60-90
seconds. In other words it doesn't go into TX at all. I get an elecraft
message on the display and my Split operation disappears After I wait for
It sounds like a power supply problem. I would look at the voltage you are
supplying both at the supply itself and in the K2's display and watch it.
I've seen people that use too small wire or have a bad connection to the K2
and as you pull current it heats up the connection and creates a voltage
Has anyone heard these guys on? Any idea where they are operating? I

heard anything. QTH southeastern VA.

Rich,
Anytime you see the Elecraft message in the display it means that somehow
the voltage supplied to the K2 has dropped significantly.
Check your power supply wiring. Use 16 guage wire or larger and be certain
all the connections are tight and the connector that plugs into the K2 is
properly
I agree with Don (as almost always :-) ). The other thing that comes
to mind is to ask if you have remembered to re-tighten the screws
securing the PA transistors to the heat sink. This sounds like it
could be a failure due to overheating PA transistors. Over that
period of time, with a

I have been using a magnifying headband from Micromark.com for building

I have had a busy week. I am also getting my exercise! The backyard
where the trees fell is now almost cleared of sawn and split wood. Much
of the brush has been stacked into separate burn piles and one of them is
now gas and ash. I was working on the last loads of wood
