[Elecraft] SoftRock Lite for K3 IF application

Good Morning All,

A number of hams have ordered a SoftRock Lite kit for the K3 IF application. 
The SoftRock Lite for this use includes a 32.768 MHz crystal to give a 
center frequency of  about 8.191 MHz.  This would require that the soundcard 
used for the application sample at 96 kHz to span the K3 IF in a good way. 
The resulting IF frequency coverage would be from about 8.143 MHz to 8.239 
MHz.  There may be some design issues with the kit I am providing relating 
to the signal and Z level at the IF output of the K3.

This morning I built an example of the SoftRock Lite for the K3 IF use and 
as I type this I have it playing on this PC using the Rocky 3.2 software. 
This SoftRock example needs a better test than I can do with my limited test 
equipment.  Is there someone on the list that already has a pre-production 
K3 and would be interested in evaluating the SoftRock for the K3 use.  If 
so, I would be happy to send them this unit at no cost if they would give it 
a try, help work through any interface issues, and report their findings, 
(good or bad),  to the list.

Please contact me at raparks at ctcisp.com if interested.

Thanks and 73,
Tony KB9YIG
