Hi Mark:
I'm no expert on N1MM logger but I have used it with the K2. I just
tried it using v6.10.10, but I know this has worked before with earlier
versions. When you use both VFO A and VFO B, you need to have 2 data
entry windows open, one for A and one for B. There are key shortcuts to
switch
Did that, thanks! It helped a little.

Hi Bill,
The K2 has adequate mic gain providing you use the correct microphone! I
use the Heil mics that were available from Elecraft some time ago. I
work all kinds of DX, establishing contact usually on the first or
second call, even in pile-ups. No change in the resistance in my KSB2
I replied to the original post on this, and I believe I came to the wrong
conclusion. My excuse is that I'm new with N1MM !
When I tested this, I activated VFO B by just switching the VFOs on the K2.
That activated the VFO B bandmap, and I concluded that VFO B was the
active (my term) N1MM VFO.
Its that time of year again. The weather is getting cold and it's time to
build another kit.
I have K2/100, serial number 5439 for sale. I built this rig in late spring
and
summer of this year. It is in new condition. I have been building kits for
30+
years including several from Elecraft.
I think there is another way to look at this. N1MM Logger is the
center point of what you do in the contest. You should make changes
in N1MM Logger, and have it change the radio instead of doing the
same thing on the radio. That way Logger is always under control. The
exception to this is

A mic preamp. You can buy some pretty serviceable mixing boards for

I should also mention that I am getting ALC indication at full power (one

So next question... anyone recommend electret-based mic's (since the

before additonal mods)

Good point, Gregg!
I have the FL1 BFO frequency on my K2 set for optimum transmit audio (using

on many signals (not enough low frequency response) so I have the FL2

Now this method is a bit convoluted, but you could put extra long leads on
an ohm meter that will measure low ohms. Start at the feedpoint with one
lead, and experimentally tap onto the antenna where you think the 55 foot
point is. If you have found the center, you will have the resistance

RC,
The nylon hardware keeps the toroid from moving mechanically and keeps the
frequency stable. It should be a simple matter to just add the hardware to
keep it stable. There should be no major change when adding the hardware.

When I constructed my K2, there were at least a dozen

the PCB board holes. In those cases I felt it was
better to mount the disc C close to the board and keep
the leads short. So in each case, I carefully bent
one of the leads at a right

Thanks for your advice in the past. I used K2 in the CQ WW SSb contest.
