hi WB6NSN
I didn't understand if you have done "something" using this old STV5730
for my antenna position, I do not remenber, it was for our TVA repeater, but now it is dead !
the house where the repeater was installed is down ...
I see this article .. inscrustation in French means OSD ..
have a look http://f5mna.free.fr/Arduino.htm
good luck
Francois
