Packet node on-air in Tucson, AZ

Node: KC9UHI-6
Frequency: 446.475
Data format: QPSK IL2P 3600 baud

I know of two options for handling QPSK IL2P
Hardware: NinoTNC -- https://tarpn.net/t/nino-tnc/nino-tnc.html
Software: QTSoundModem -- https://www.cantab.net/users/john.wisem ... Modem.html

The NinoTNC is using mode switch setting 0101, 3600 AQPSK IL2Pc 1800 sym/sec on 1650Hz carrier
For QTSoundModem, select QPSK AX.25 3600bd centered at 1650Hz, IL2P Mode RX+TX, Send/Check CRC.

BBS, DX Cluster, and wormholes to the world are all available
