[Hamlib-developer] rigctld and multiple programs

[Chris B. <g3...@cr...>]

I have an Elecraft K2 which I can control ok with gpredict. I have built
a Softrock receiver into the rig on the mixer output and using the Quisk
program I can display a useful spectrum. See

http://james.ahlstrom.name/quisk/

Although Quisk has a hardware module to support the K3 (and is reported
to be ok with the K2), I intend to write a hardware module for Quisk so
it integrates better with my setup (eg compensate for the offset caused
by the Softrock, and for the way the K2 adjusts its BFO frequency
between modes and filter bandwidths without telling me). This will take
a while as I have to learn Python first and generally get back into
writing software after a long absence.

It occurs to me that I should probably write a hardware module so that
Quisk will talk to hamlib via rigctld. This will be phase 2 as I will
first adapt the K3 module and use a serial port where I can see what's
happening!

What I would really like to do is find a way of sharing the K2 between
gpredict and Quisk so that I can spot on the panadapter a satellite
contact or CQ somewhere within the passband, click on this, then let
gpredict take over the tracking.  In the man page for rigctld I see
this:

This allows multiple user programs to share one radio (this needs
testing)

Can anyone give me some details of what is/isn't/might be possible?
