I bought a cheap DMM like that a few years ago to help align my K2. It

used it for since. Similar to you, I have a more than 30 year old

higher circuit loading
Due to impending arrival of a K3 I am offering for sale the Ten-Tec
transverter I have used to operate 6m using my K2. (See

This transverter was built from a kit several years ago and has been
set up to work with the basic K2

Bob,
You likely have an unsoldered or poorly soldered connection on the Front
Panel Board.
Separate the front panel from the board and you can probe most
everything on the front panel board.
Do a visual check and you may be able to find it - check pin 1 of the U1
socket, that is a common
The Harbor Freight DMM in the reddish case is very nice and works well.
This goes on sale for around $4 frequently. But the Harbor Freight DMM with
the orange case is pretty lousy. This goes on sale for $3 frequently.
Anyway, this has been my experience. I bought two of the reddish case DMMs
I got a wavetek meterman about 5 years ago, under $100.00

The Yaesu does 6 and 2 meters, plus 220 and 440.

P.S. As a former GM of HP's division responsible for DMMs, I should
suggest you spend $8k for a 3458A. :-)
maybe ... but I can drop a Fluke, pick it back up and keep using it. What
happens when the 3458A gets dropped?
BTW -- who uses 8 1/2 digits of precision? Who calibrates it?

I lucked out several years ago at Sears and found a combination
digital/analog meter. Has all the usual DMM functions, plus an analog
movement. Wonderful for peaking, etc! Unfortunately, I think Sears has
discontinued it(naturally), haven't seen anything similar for quite some
time.

Hello Don,
Those pin 1 places have round solder pads while the other pins are
rectangular pads and it is easy to miss the pin 1 solder connection and
not notice it.
This happened to me as well, when I build K2 #6177 in July.
The resistance check for the control board did not fit and an

Mine has failed *twice* now (requiring a replacement jack both times).
I am kind of fearful to plug anything into it anymore.
For me, at this point, it is almost predictable that it *will* fail (YMMV).

While not an 'easy way', there is a way. Take a look at the CW PTT for
the K2 article on my website http://w3fpr.qrpradio.com.
The circuit interrupts the paddle lines (and the front panel mic PTT if
you add that part) until an external signal (active low) is received.

Glad to hear Elecraft is implementing auto-sensed transmit CW, a necessity
for weak-signal DXing on VHF, where SSB and CW are often used interchangeably
on the same frequency. The way it was described in the FAQ, though, gave me
some concern, because it wasn't made clear that the auto-sensed

INFO 080 means that the AUXBUS signal (which is the one that
communicates between the various processors in the K2 and its options)
is not fully functioning.
The usual cause is a fault in one of those options. So, to
troubleshoot, remove the options one at a time (starting with the

There are three modes available.
1) PTT
2) Semi-QSK
3) QSK
In QSK mode, you just hit the key to transmit.
Vic,
That clarifies part of it - but 'transmit mode' apparently is not
defined as the presence of RF - it simply means that the K3 will not
return to the receiving condition (if I understand what you mean
correctly). Please confirm or provide an alternate explanation of
Transmit Mode.

Does closing PTT when in QSK mode inhibit a return to receive
until the PTT is released? - that is the only thing I can think of.
Yes.

Since no one has explained the difference between 'Transmit mode' and
