Hello Dave,
I hope that your warning about the effect that a magnet can have on cores
will be noted by those who use magnetized screwdrivers to recover hardware.
To recover parts that have gone AWOL I would srongly recommend the use of an
inexpensive "Grabber" tool, which can also be used to in

to get it started. I bought a brand new Stanley set for my K3 assembly,
David and all,
There already is a message for HI REFL which appears in the VFO B area
when the SWR exceeds 2.0.
It is transient and could possibly be overlooked. If a log of errors
could be made available, that might be helpful when troubleshooting.

As a fellow software professional, I agree with you in theory.
Was the ordering info, and all of the pricing posted on the website Thursday?
If so, I can't seem to find it.

Gentlemen, I'd appreciate a link to any manufacturer's or engineering data
you have, since I have never seen a ferrite or powdered iron core that was
permanently affected by a magnet, nor have I ever encountered any
manufacturer's warnings about magnets around modern electronics in the
equipment I'
2m is nice, but I'm with Frank; I'd love to know if a 70cm module will also
be forthcoming. In my area, 70cm gets a lot more use than 2m.

It's a commonly known problem for NiZn ferrites. Whether a mag mount
antenna yields sufficient field to cause the problem is a different
question.
For specific literature cites:

Hi Jan,
The scan function sets its own threshold automatically. I have plans to
improve this further. But meanwhile, you can turn the preamp off or the
attenuator on (or narrow down the bandwidth) to change the threshold.

Good idea, Jim. We could log all error messages and warnings in EEPROM,

Hi Don,
You're right: "HI SWR" is a transitory message. It should probably
switch to a permanent message ("ERR SWR"), requiring a switch tap to
clear, if the conditions persists long enough to force a drop into QRP
mode.

Hi Paul,
All I know is the RX EQ is still enabled in data/cw so my guess is the TX EQ
remains enabled as well.
Shouldn't be the case, because RX EQ has a negative effect on Spot and Text

Disabling RX and TX EQ for both CW and data should be better IMO, since the

TxEQ is applied tyo all modes which use an audio input: SSB, AM, FM, DATA A.
Making TxEQ by mode is "on the list."

Hi gang,
The weekly Elecraft SSB net will meet tomorrow (Sunday, 5/24/09) at 1800Z.
We will start at 14.316 MHz, and QSY if needed. The net control is in
western Oregon, but we will need a good east coast or midwest station to
relay a few west coast signals that may be too close to net control.

You are correct, Dave. There is no Tx EQ in DATA A Synchronous.

Michael,
If you have the new 2SC5739 transistor at Q6 (plastic tab), it will run
hotter than the previous Q6 2SC2166 (metal tab)
To tame it down, change R46 from 270 ohms to 330 ohms which will reduce
the bias voltage during transmit. Q6 should cool down during receive.
OTOH, if you have the 2
