Since you have the SDR-IQ, I can address use of it with the K3 (as I

knowledge. You can use the SDR-IQ by itself and tune from 500-Hz to

become a new niche product. If Elecraft chooses to not develop the
concept, there is no reason that it cannot be done by someone else.

Just a note to those with or looking to acquire an Astron PS for a
100w HF station:
I have owned an Astron 35VM for many years (bought new in 1981) and
only had to replace the regulator chip when I reversed bias trying to
use is as batter charger. Otherwise perfect service. Being an
analog
I recently purchased a Micro Keyer II from a fellow ham New in Box never

Lance,
Very good! On digital eme I found that freq stability is the more
critical parameter vs freq accuracy. WSJT (JT65) typically displays
up to 2.5 KHz of spectrum so one can find signals that are off center
frequency (on eme Doppler shift results in this as normal), but
keeping on a
I am also very interested in any applications for the Raspberry - the
Barbie doll for hams and computer geeks. I am just beginning to learn my
way around it, but its possibilities seem endless.

I have a 6500w electric-start Honda which had similar battery
problems. Mine were that I did not run it often enough and cold

12v 500ma charger on the battery which is just enough to maintain
it. My generator is wired into

As you know I run the K3 for eme, as well. I chose the new L-series
DEMI transverter so it was built to my spec as perfect interface with
K3. It seems most of the ham world is unfamiliar with separated Rx
and Tx (though Elecraft did a super job on the KVX3 option...but then

As a current Canadian Avionics E licenced mechanic with over 30 years
experience, including quite a bit of HF, I can tell you that there are
many makes and models of HF gear, including Collins, Bendix/King,
