[aprssig] Thinking about YAAC

Regarding your data receive issues with the MFJ-1274, you might try using the Kenwood port type in YAAC instead of the Serial_TNC port type. That receives traffic in the TNC2-compatible command mode, but can't transmit (because the Kenwood D700/D710 won't accept computer packets in APRS mode rather than raw packet mode). At least that will tide you over until you can get the new (?) EPROMs for your 1274.
Re: RAM size: look for the chip part number on the RAM ICs, look them up in a databook, and divide the sum of the chip sizes by 8. That will tell you the RAM size of your 1274.Re: the Yahoo group for YAAC: I am planning to move to groups.io this week. Would have done it earlier, but the XYL wanted the house prepared for holiday guests. Now to find out how much RFI comes from LED Christmas lights....Andrew, KA2DDOauthor of YAAC

For mobile use I will be using an RPi 3B+ with a TNC-Pi, so I won't need Direwolf in that application. The TNC-Pi will provide an adequate interface between the radio and computer.For the base, I have a Linux desktop computer running Mint currently connected to an MFJ-1274 (MFJ-1270B with tuning indicator) to the radio. If I were to use Direwolf on the base, I would need to add a soundcard and homebrew some kind of interface for the PTT as well as fabricate new cables. Right now, I have a very simple configuration with a single serial cable going to the TNC and a single cable going from the TNC to the radio and it all works very well. At least with Xastir. With YAAC, however, I get nothing displaying on the map. In the configuration window for the interface where it has the TEST PORT button, I see plenty of data coming in from the TNC. Just nothing displays on the map or in the RAW DATA window.Michael WA7SKGGreg D wrote on 12/8/19 10:06 PM:> I'm running YAAC and Direwolf on a Raspberry Pi 3B in my car.  Works> pretty well, though with the Pi tethered to my Smartphone along with the> RF link there seem to be some combinations of Digipeating, iGating, and> messaging that don't seem to work quite right.  Messages didn't get> delivered in one direction, and I've never figured out what to do about> it.  If you're all RF, it works great.> > As Stephen noted, the sound card TNCs work really well, and the Pi's> GPIO pins make the PTT function easy to implement (no need for VOX).> Just be careful about the voltage levels so you don't damage the Pi.  A> 1-transistor buffer is usually required.> > Good luck,> > Greg  KO6TH> > > wa7skg wrote:>> I'm looking at alternatives to Xastir for an APRS client and ran>> across YAAC.
