Read the last few articles with interest .
May well be a FAQ - but do many groups use packet for connecting a
network system ? I wondered what problems other than getting out of
sync again it would pose ? At least it should help with RFI on the
network cables !! We had thought of using a radio connection over
perhaps half a mile to separate "Run" and "Mult" stations - although I
guess a set of decent filters at both ends could help solve the problem!
