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).
