Re: How to decode GMSK CW Signal

Have you seen this: http://uz7.ho.ua/packetradio.htm The GOMX decoder is similar, so it should do it.

Building FLARM

Can someone give me a quick rundown on building FLARM on Linux not Rpi : http://download.glidernet.org/

There are 2 parts and i can't seem to get it built. Should be straight forward.

Cheers!

Re: rtl_fm -> left and right sox output?

Quick update: I am now running the 2 frequencies (1 per dongle, i tried using 1 dongle setup to scan 2 frequencies with the squelch command like the RTL-FM scanner setup but kept hitting problems) into 1 instance of PDW and i haven't seen any decoding issues. CPU is down to 15%. I'm very happy and s...

Re: rtl_fm -> left and right sox output?

no probs: - rtl_fm -d 0 -p 57 -g 20 -r 12.5k -f ***.****M | aplay -r 12500 -f S16_LE for each dongle and frequency $ pacmd load-module module-combine-sink sink_name="whatever" slaves="alsa_output.platform-soc_audio.analog-stereo" for each output to PDW. I have noticed that the terminal has to stay o...

Re: Grounding of Active Antennas Like The Mini-Whip

I suppose it may come down to what type of soil you have, i have read in some scenarios several earth points have been used in poor conductive soils. Mine's pretty crude, i just split the RG-58 at the base of the mast (4M galv. pole with a 1M pvc tube at the top). The braid on both ends has a crimpe...

Re: rtl_fm -> left and right sox output?

Been faffing about with the pi for a couple of days and now have 2 dongles (using rtl_fm) feeding 2 instances of PDW via the pulse audio commands mentioned in the link you posted. Working well using between 24 and 30% cpu. The RPI 3 is an awesome little unit!

Re: Grounding of Active Antennas Like The Mini-Whip

I have a mini whip i use for long wave in a rural environment, and grounding does make a difference here. The noise floor is lower with the antenna earthed at the base ( 4 ft star picket driven down so only about 3 inches show).

Re: rtl_fm -> left and right sox output?

Thanks, awesome info as usual. I'm going to hop right into it this week and we'll see what comes of it, will post the outcome. My RPi 3 turned up last friday so i have multimonNG running on that as well, not much chance of wine running on the pi unless i use a paid program to host it. Incidentley, a...
