I am now evaluating Direwolf for HF packet reception on 10.1476MHz. It’s running on a Rasperry Pi 2 with the cheapo Cmedia sound card and the performance looks extremely good. I just need to figure out why I’m getting broken pipe errors though.
I haven’t yet decided whether to run it as stand-alone igate or use it as a TNC in conjunction with Xastir as it provides either AGWPE or KISS type interfaces to external programs.
Update 13th May – I reduced the number of parallel modems from 7 to 3 and this seems to have cured the broken pipe errors. I’m now gating received traffic to APRS-IS using the built-in client. Traffic reported can be seen on aprs.link.
