That means , it needed a sound card based interface to handle the tx/rx audio , via mic socket - ok
PTT ... is there VOX ..or has to be hard wired ?
Some confusion round the cat options , CAT is only for housekeeping and not , operational as in frequency/mode/ptt etc ?
CAT - PTT is NOT ? supported via the cat function ?
Ideal interface is then , one with sound-card audio in/out
and ptt that can be activated from vara directly ?
