I am seeking to buy TNC hardware for the new K3GWU station (Foggy Bottom Campus - George Washington University).

I'm limited to a small budget at this moment, and do appreciate those kind hams that have donated racks, radios, antennas, cables, and so forth. But now, I need a packet radio modem/TNC for digital communication needs!

We have an Icom 706 (original) and a FT-857 (original) in working condition now, and a few midland commercial radios reprogrammed for ham radio fixed frequencies.

I've read about Signalink USB and also see the various Kamtronics and Timewave products. Any tips for for AMSAT packet use? for ISS packet use? TNC-X ?
