to the existing Direwolf SDR+APRS guide, which covers off
setting up an igate pretty well: <a

In this guide, there's a link to a script that will tune to a NOAA
frequency and re-calibrate an SDR TV stick (

What would be a good high-stability signal source here in VK for the
calibration? I used to use the kal program to calibrate against GSM
transmitters, but that's not possible any more. I'd think the
trunking control channel for an emergency services' channel would be
stable, strong and always on? Or DAB+ transmitter, or..?<br>
