crystal filters with respect to the I.F. center
Gene W3ZZ (who owns a K3) is saying the
two rigs have very comparable RF performance. I might quibble that he
omitted BDR in his table but perhaps that's more of an HF issue than
VHF
(Gene's focus in the VHF column). For both Phase Noise and BDR, the K3
exceeds the 5000 by ~15 dB (not
Ron,
We haven't been able to reproduce this (yet).
Are you using the latest beta release (2.82)? It includes a menu entry
called CONFIG:AFSK TX. If you set it to FIL ON, you'll have a 400-Hz
filter around the RTTY transmit tones. Please try that. It should clean
up noise, if that's the issue.

So how about Elecraft offering a board swap for those of us who do not
wish to do the mods themselves.
Hi Gary,
We'll be happy to swap any module that you don't

James,
The XV432 itself *does* cover the full 70-cm range. If you use it with
a rig that covers 28-32 MHz, you'll have this capability. But the K3
only covers 28-30 MHz.

Thanks for the information. I didn't realize that the XV432 didn't
cover
the whole 70cm band. This is
Gene (W3ZZ), the author of Comparing VHF + IF Strips in the March
2009 QST, just got back to me with a correction to his article. On page
90, table 2 should show -138 dBm for the K3, and -132 dBm for the
SDR-5000 (the two figures were transposed). A correction will also
appear in QST.
Thanks,
It gives us an excuse to meet for lunch once a week :)

Colin,
You might have VFO B in the wrong mode. Try doing AB twice, then go
into split.
If this doesn't work, try loading the latest beta-test firmware (2.82).
I'm sure we tested split on each release, but this rev might have a
relevant improvement.

Bob,
I've had very positive feedback from a dozen or so K3 customers who
have used the new birdie removal feature successfully. This will be
included in the next beta release.
But don't take my word for it :) I'm sure others will weigh in.

Steve,
If you're using the XV144 with a K2 or K3 you can set up a transverter
band, with a per-band offset of +/- 9.99 kHz. The VFO dial will then
read accurately for each transverter.

Is there any way to put in a tuning
I could change the firmware so that when in you're in the SIG RMV menu
entry, it could slew the VFO over the present 100-Hz segment (i.e.,
from .000 to .099) once per second. This way you could hear the full
effect of each SIG RMV step without having to exit the menu and move
VFO A manually.
Hi Russ,
What you see when changing bands is the MHz value that you're tuned to
on each band. You must have the VFO tuned below 14 MHz on 20 m.
