[Freetel-codec2] DRM Mode H

[Kevin Otte]

Just joined the list so I don't have a thread to reply in, but I saw
some discussion of DRM as a source of modem inspiration. Some years ago
there was an adaptation of DRM to ham radio SSB radios. It was dubbed
"Mode H" and its description is at:

You can see working examples of this DRM mode in the SSTV programs for
Linux:

Qsstv
TRXAMADRM

Works quite well on both HF and VHF.

I thought QSSTV was analogue
 it was last time I tried it.

The latest versions of QSSTV, in the Debian testing repo IIRC, have DRM.

Hello Stuart,

I thought QSSTV was analogue… it was last time I tried it.

Qsstv has evolved quite a bit since you last saw it. Give it a look:
