Hi Lyle,
Thanks for the tip.I am using 2.46, and it didn't work until you pointed
me in the right direction.
Since I had the AF Gain set to HI before I installed the KRX3, I now
disabled the KRX3 and changed AF to LO. Then I enabled the KRX3 and changed
AF to HI afterwards, and that
Make sure that the KRX3 is fully mated with the SUBIN board
connectors.

Is the phase noise performance of the K3s on Ducie the same as that from later
K3s? I dimly recall that some early K3s had an issue which was later fixed. I
know you had to supply their K3s quite early on in the production run, so,
perhaps they are now even better.

The foster plug pinout is different. You will have to re-wire the mic
plug to match the Elecraft pinout.
Elecraft mics work FB, and the non-amplified, non-electret microphones
from Kenwood will also work directly because the pimout does not use
either pins 5 or 6 of the mic plug.
I've done all the construction up to the transmitter alignment on the base
K2. I do not have a signal generator that puts out 0.14 volts. Bought the
N-Gen and it doesn't provide a strong enough signal for signal tracing. So,
how do I find my problems cure?

Ron,
Does the receiver work on all bands? You can tell even if there are no
signals available - turn the gain up to the point where you can hear a
bit of noise with no antenna connected. Then connect an antenna - if the
noise level increases, then the receiver is working. It may or may not
The new bandstacking memory selection is really nice. CONFIG: BAND SEL now
permits the 160 m thru 6 m (minus 60 m in my case) to be placed in ascending
order in memories 0 - 9. The five 60 meter channels are assigned to 10 - 14
and scroll in a loop. I also like CONFIG: BND MAP to temporarily
Yes this is much better; makes a big difference. You can arrange your
bands in any order throughout m0-m9 and, more importantly, access them
randomly (in the computer RAM sense of the word). As well as being
able to lock out bands for the Band UP/DOWN switch.
This is really all I need for

Sweet. Thanks Elecraft! You must of been reading my mind. It is
hard to explain exactly how annoying it was recently having to keep
stopping on 60m when I was going back and forth between 40m and 80m

Thanks all. From what I read here it is most likely a combination of K3
settings and logging software problems. Years ago, I worked closely with
Scott, N3FJP to get the FT1000MP working with his software. He was most
diligent and appreciative of my input. I will continue to dig.

Yet Another K3 Yarn
It was dark snowy night last winter, 2007 and I was staying warm in the
shack by the glow of my SB-200 and the propane heater in the corner
rag chewing on the NW 10m net. The snow flakes were just piling up on the
ham shack and the nondeterminsitic pings and clicks from
The only remaining annoyance is what happens when you leave
the ham bands, say if you leave 30m ham band and go into the
31m SWBC band: the 31m band gets set as your 30m ham band.

I sometimes take my K3 for a visit to a neighboring SW band.
When I'm finished SWLing, I just press [A/B] to swap the (still-in-ham-band)

band as well.
Two buttons, no problems.

The difference is that if you have BAND SEL in effect, an MV recalls
the last-used frequency on the target band, not a fixed frequency. Thus
it's just like doing a BAND up/down.
Example: Suppose you're in BAND SEL mode, and you assign switch #4 to
40 m. Go to 40 m, then move the VFO. Then

What's new is that you can now go to the last frequency used in any band
-- just like band up/down -- rather than to a particular memorized
frequency.

Yes, Tom, that works if you stray out of a ham band with the VFO. But
if you jump around to several different SWBC bands using direct memory
M-V access, they will reassign some of your ham bands to SWBC freqs.
You then have to bandswitch to each one and recall one of your

Also I should note that in my laptop waterfall display, the width is
only about 400. I have for FL1 the 8-pole 2.8K and for FL2 the 8-pole

I think that you haven't assigned FL1 the 2.8K filter for data mode in the

It was my impression, based on two sources, that for PSK31, it was
best to use the 400Hz filter (FL2 in my case), not the 2.8kHz (FL1 in
my case) filter. Was I wrong?
You must use either a 2.7 or 2.8khz filter for transmitting all modes except
AM and FM, which require separate filters. The
The noise you see on the waterfall should correspond with the DSP BW

Indeed, I can increase the width by adjusting the DSP BW width, but
only to a small degree.

Haines,
To adjust the audio gain, you set the K3 into TX TEST mode (hold the
MODE^ button), not TUNE. TX TEST allows you to adjust the transmit
controls without actually transmitting RF.
Check to be certain your soundcard is actually producing audio - check
the soundcard controls in your

To amplify on my previous email - I will assume your 400hz filter occupies
slot 5 and the 2.8khz filter occupies slot 3.
In the CONFIG menu, select FLx BW, where x will be a number 1 through 5.
*Select filter slot 3 by pressing the 3 button on the keypad.
*Be sure the BW (bandwidth)

I would try it. We had two K3's in use at the Holland (MI !) field
day site, K8DAA on 20 meters. One on phone the other on CW. Sometime we
were within 50-75 kc's , oops, kHz of each other, with no ill effect.
The antennas were maybe 200 feet apart at the most, and they were not

I downloaded the new 2.58 beta with no problems but the regular group I

We used to do that kind of thing all the time in the old days of
tube-type radios. I used to keep an old Drake B-line around just for
use on Field Day. It wasn't until the advent of solid-state
fully-synthesized radios that it became impossible to do phone and CW on
the same band on FD.
