The SCS Tracker DSP TNC works very well, but we noticed some additional energy transmitted above and below the primary Robust Packet 500 Hz bandwidth.

Waiting for a spot on the mountain shouldn’t prevent adding tremendously useful HF access to the VAPN system so that’s exactly what we are going to do in the lowlands.

Negotiations for hill top space continue while we consider adding HF to the current 2m prototype.

The SCS Tracker DSP TNC wins its way into the overall design of the VAPN.

Is packet operation on 160m an idea worth testing?

New ideas applied to an old mode help keep Packet Radio relevant in the 21st century.
