Listener Forum / Re: HF CAR Request ?
« Last post by dave on Today at 08:41:45 AM »Have some more receiver capacity now and made some changes. Still a work in progress. New feeds so far:
HF CAR-A 13297 NH
HF CAR-A 8825 NH
HF NAT-A 13306 NH
New HF model is SDR receivers only (combination of KiwiSDR 1 and 2 models) with a Linux-based client system running kiwiclientd.py (Python code). That system has been in operation for a while but a legacy Linux system feeding from a few analog receivers failed recently. No intention of resurrecting it right away. It changed frequencies on those receivers twice per day, attempting to follow HF propagation. With daily, seasonal and sunspot changes over time it was hard to keep a reasonable frequency change schedule up to date. Doing it all via SDR and over the LAN is a lot easier and more flexible. Also, fewer cables and lower power!
Still have to add some of the lost NAT frequencies back.
Overall review and more suggestions welcome. Too far away from the West Coast to think about Pacific frequencies. Perhaps someone closer to the West Coast will get interested in feeding those.
Talked to a pilot friend a few weeks ago who flies the WATRs routes and less and less traffic is on HF these days. SELCAL checks and backup for emergencies. The rest of the comms are on CPDLC.
