RPI, Direwolf, RTL-SDR dual frequency receive

Jose Ng #1747 I installed Direwolf on a Raspberry Pi with RTL-SDR and can decode APRS packets OK with the command: rtl_fm -f 144.39M - \| direwolf -c sdr.conf -t 0 -r 24000 -D 1 - Is it possible to have a dual frequency receive with the RTL-SDR? I tried this command for dual frequency received but the program quits with message End of file on stdin.? Exiting. rtl_fm -f 144.39M -f 145.01M - \| direwolf -c sdr.conf -t 0 -r 24000 -D 1 - Jose / HP2AT
David Ranch #1748 开云体育 Hello Jose, The rtl_fm tool only allows demodulating one frequency at a time but I recently came to learn of .? This software can support 8 "slices" per SDR dongle and was designed with the Rpi in mind.? --David KI6ZHD On 01/23/2017 08:15 PM, Jose Ng hp2cwb@...

Jose Ng Lee #1750 ? Hi David, ? Thanks for the RTLSDR-Airband info.? I will play with it.? Maybe there is an easy way to interface it with Direwolf.? I have play before with other RTL-SDR software like aisdeco to decode ship beacon on two frequencies and acarsdeco to decode airplane messages on 3 frequencies.? So, thought it should be possible to decode 2 or 3 frequencies within 2.4 mhz. ? Jose / HP2AT ? toggle quoted message Show quoted text ----- Original Message ----- From: David Ranch dranch@...
