Hi,

after Robert's PA2RDK inniciative we have designed APRS with DRA818 module. APRS is based upon Arduino, it has a single two-colours OLED and possibility for FM communication on one selected channel - that is a feature that "usual" APRS modules that are on the market do not have. But after testing it for over a year now I can confirm it's nice to have one FM channel available for chat!

Description of APS module can be found on this link (Razzies magazine).

KITs for PI4RAZ club members are in preparation and will be shipped.

Robert has in the mean time also developed version with full colour TFT LCD which offers functionality of APRS and full featured VHF transceiver. See article here. For this version you have to add to APRS board just another Arduino board, TFT LCD and few components. And you've got APRS and full featured VHF transceiver.
