Digital modes for amateurradio
I started my first digital voice project in 1982 together with Hartmut, DC2BI; about 8 years before digital mobile phones came up.
May be this was the first ham digital voice project worldwide.
Unfortunately processors were too slow at these times, and there was a part - success only.
We stopped the project 2 years later.
That is the reason, that I am interested in digital voice all the time.
My experience with the ard9800 (AOR)
Some about windrm and drmdv (not up to date)
A lesson on this subject
I use Easypal and have written the german helppages (see helppages left)).
