Above and beyond the sound card it has an onboard GPS and PTT/CSQ lines that use the RPi GPIOs. It is not a complete solution. To make it work with Xastir still requires additional software that: a) Can use a sound card to decode/encode ax25 packets. b) Can use the RPi GPIO lines for PTT. c) Software to access the GPS (gpsd) if you're taking your RPi mobile. One of the software modems that can do this is Direwolf. For the GPS I presume you can use gpsd. Very likely none (or few) of us on the Xastir list have DRAWS boards but we can infer what it will do from the above information about DRAWS and our experience using other soundcards with Xastir. Direwolf is one of the best software modems available and when coupled with DRAWS should out perform most if not all other solutions. -- Ken - N7IPB Email: n7...@wetnet.net JID: n7...@jabber.wetnet.net SvxLink Repeaters: http://pnw220.wetnet.net PGP Sig: F42B EF90 3CD3 31C7 3056 122E 993A 7B2E 5138 C42A “Contrariwise,' continued Tweedledee, 'if it was so, it might be; and if it were so, it would be; but as it isn't, it ain't.

Well I've never heard of this hardware, so probably the chance of anyone already using it with Xastir is very low. Then if no one replied at all, would you complain that no one answers?

I suspect the reason you have not seen the specific type of reply you are looking for is simply due to a lack of Xastir users (on this list) that own a DRAWS Hat.

Re: [Xastir] Xastir with DRAWS
You asked for comparisons and I gave you information for you to make your own conclusions as there is no perfect answer. DRAWS alone will NOT do what a TNC-Pi will do as you also need to run software (say Direwolf) to act as a complete TNC. If you can afford the DRAWS board and have time to configure all the software, then buy that as it will work. If you don't have the time or prefer a lower budget, buy the TNC-Pi. Now in this email, you are mentioning other modes that you might want to do which is entirely different. The TNC-Pi will NOT support any of those other modes. The DRAWS board can run those HF modes but with entirely DIFFERENT software (say Fldigi). I cannot speak about if the DRAWS boards can support both DIrewolf+Xastir and Fldigi running at the same time but I believe it's technically possible as it's has a dual port soundcard on it. The biggest problem will be the limited CPU power and RAM on the Raspberry PI running everything in parallel. --David KI6ZHD On 12/08/2018 07:48 PM, Michael wrote: I fail to understand why it is so blasted hard to get an answer on anything on ham radio related forums.

I am trying to make a decision on buying a DRAWS Hat for the RaspberryPi. I want to run various digital modes/applications including MT63/PSK31/etc. with fldigi and APRS with Xastir. My question seeks user experiences with these apps and DRAWS. Please attempt to limit responses to that question. Thanks, Michael WA7SKG David Ranch wrote on 12/8/18 11:53: NW Digital's DRAWS HAT boards is just a dual-channel soundcard with some PTT circuitry and a GPS. There isn't anything really magical there beyond very nice integration on one PCB for people who don't want to cobble something together themselves. It also offers a good set of documentation and potentially offers more than just community support to get you going. Your question probably should be more like: Is anyone using a souncard TNC like Direwolf, Tom Sailer's Soundmodem, etc. with Xastir vs TNC-Pi I'm using Direwolf on an Rpi with a Syba USB sound device and it works very well. It's TNC is generally able to dig out packet decodes that most PIC-based TNCs (like the TNC-X, TNC-Pi, etc) cannot. The new TNC-Pi9k6 could be a different animal as it has a lot more CPU power but I haven't heard of any real decode comparisons yet. The older Direwolf documentation used to have a comprehensive comparison table against other TNCs in the "10.1 WA8LMF TNC Test CD" section but newer versions dropped it. Here is an example of it from the Direwolf 1.3 docs. Overall, Direwolf's decode performance has only gotten BETTER since then: https://github.com/wb2osz/direwolf/blob/a7391b49998d0b759a89d3329a5b88f4cdf92936/doc/User-Guide.pdf --David KI6ZHD On 12/08/2018 10:55 AM, Michael wrote: Is anybody using Xastir with DRAWS on a RasberryPi?
