The process of finding compatible packet radio hardware and software to transfer digital data files has been fruitful.
The only downside is I was unable to make the KPC-3+ TNCs included in the emergency packet kits work with the QtTermTCP software.
I was in contact with the software author G8BPQ and we narrowed it down to a USB driver incompatibility that came into play when using a USB to serial adapter.
However, the Kantronics units can still be used as temporary vias (think repeater) in the data path that doesn't need a computer, if an emergency required a longer path between ends.?
The good news is I've tested both Raspberry Pi (Linux) and Windows versions of terminal program QtTermTCP (software) with the NinoTNC (hardware) doing file transfer tests over packet radio and they work hand in glove.
There is a pre built NinoTNC surface mount part version going on sale for $70 soon. While I'm sure it will be a winner, I would wait until the 2nd or 3rd batch is offered up.? That way they will have found any bugs and rectified them.
Printed plastic cases are around $10/ea for the originals, I would assume the new cases will be priced similar.
The other upside to the NinoTNC is flexibility. It has 16 different packet speed/modes, switch selected - 4 of which offer higher speed HF modes now legal in the US.
If folks are interested, I'll post some links here as they become available.
