Longmynd info

[Richard-g8jvm]

Hi
just re-subscribed after getting the QO-100 NB Rx downlink working, 1.2mtr offset dish and a POTY, I have fitted a TCXO to one side of the LNB, which I'm a bit disappointed with the Frequency accuracy 37KHz error at 10489MHz, Abracom ATX-11 series.
As it a dual LNB I might as well use that to receive NB DATV from QO-100.
I see the longmynd software is linux based and I exclusively use linux where ever possible, where can I find out more, which issue of CQTV, and what else is needed, been licensed 50 years now, so maybe time to plat with a bit of DATV

I'm very aware that the version of debian used with raspian is a long way behind the release I'm attempting to compile with
any ideas

Sorry Richard, I know absolutely nothing about Linux. I know the seemingly endless 'minor tweaks' that RPI updates implement seem to break what went before. Does the Github repository give any 'OS requirements' or advice I wonder?
Maybe the authors can chip in with suggestions....

OK Gareth
I suspect what I seeing is lack of backward compatibility. I use the same file management system LM is ubuntu lib based, debian uses the same but much older.
