Andrew,
During the initial build, it is important to peak the bandpass filters
using receive to be certain they are aligned in the correct bands - this
is especially important on the higher bands.
After doing that, the bandpass filters are peaked using transmit where
the peak is more easily
Hi Gary,
You've already had a lot of great replies...
Thought I'd throw my two cents worth in at this late date:
The second RX is well worth having particularly for the low bands where
you're more likely to be using a separate RX antenna. Too, if you're gonna
be DX, it's VERY useful for

1. Even when NOT on 2 meters (K144XV off) my K3/100 seems to run hotter
than prior to installation, e.g. the fans run more frequently. Is this
general experience? ...and is it simply due to the changes in airflow
due to the presence of the K144XV structure?

Hi Doug,
The K144XV here had an +850 Hz offset when received. There is about
25Hz of temperature drift as well. Combined, the 875 Hz could be
canceled using the offset setting.
12.5 KHz seems excessive, and that's the highest I've heard of.
Note: My K144XV is one of the first ones produced
Keeping a DCM-style record of each K3 would be virtually impossible.
Factory-installed K3 options could be tracked by the original
buyer/owner/builder but not by serial number, since many owners have
multiple radios. More to the point, options are also
bought/sold/traded in and out of K3's. The

It depends on the purpose for connecting the K3 to CI-V bus. If

Knut,
Thank you for your suggestion. As mentioned in my email about the best I
can do with Method 2 is about +/20 hz. I've tried it numerous times. When
adjusting the frequency I hear a dead spot 25-40+ hz wide that has no
womp-womp-womp. I take half of the width and set the frequency there.
12.5 kHz sounds like you have one of your signal source radios one
channel off in tx frequency. That is way more than we normally see here.

Jim,
Since you say you have hearing loss, that can prove difficult - I would
suggest a visual aid.
You might try using Spectrogram (or another FFT audio spectrum analyzer)
when attempting Method 2.
You should see the spike from the sidetone and the spike from the WWV
carrier on the display,
Thanks Alan.
Since whether or not Elecraft develops a K2 / P3 interface would be a matter of
economics...
I won't be holding my breath waiting for an announcement.
But it sure would be cool !

Matt - Interested to know that your K144XV is stable. I am afraid that
mine drifts horrendously (almost 100Hz per 5 minutes). Hence I have
ceased using it until a fix is produce and have reverted to my XV144

While I don't disagree with other people's suggestions that visual aids

Rather than try to listen for zero beat I offset the dial reading by 1kHz and
use a computer sound card program to measure the frequency of the audio
tone. Fldigi is a good program to use for this.
