[OZAPRS] TNC320

[Tony Hunt]

Good work Larry .. I just have it beaconing every 30 mins at the moment not connected to anything useful on the serial port. I see you heard a frame from it in the wee hours this morning at 1601 UTC . 30m seems typical at present.

One odd thing is that it didnt hear 3MY till well after 10am. All night it was being heard by the more distant gateways and picking up their beacons VK2 VK4 VK7 ZL etc

    Just having a fiddle around with a PacComm TNC320 here on HF. I dont know if there are many of these around . They seem to use the XR2206 and XR211 chips for the Tone mod/Demod . I could not find any info on what tone pair it uses so I got a frequency counter out last night and found it was 1600/1800 Hz tones on HF. Ive got it working on 30m presently.

    So an update for this page adding the TNC320 to Group C modems/devices  may be in order.
