JawnCon 0x3 · Arcadia University, Glenside, PA · October 16–18, 2026
Simplex 146.580 MHz On Air
SSTV: 145.500 MHz (Robot36) | APRS: 144.390 MHz (RX only)
The ConHam simplex frequency of 146.580 has been in use at DEFCON since at least DC16, though probably much earlier than that. Standardizing on a single frequency made it much easier to find other hams in a backchannel way, without depending on sketchy WiFi and a crazy game of telephone - and it works just as well in Philly.
