CODE NAME DESCRIPTION
?74
Transceiver
Control Modes
Value is returned in the form: “q.00a.01b.02c.03d”
a = 0 if transceiver in old RF card mode.
= 1 if transceiver in new RF card mode.
b = 0 if PT & CT are channel specific.
= 1 if PT & CT are global.
c = 0 if CT squelch control is static.
= 1 if CT squelch control is dynamic.
d = 0 if scan stops after a PTT press/release.
= 1 if scan continues after a PTT press/release
?75
Timing and Delay
Parameters
Value is returned in the form: “^.00aaa.01bbb”
aaa = DVI Shutdown Time (obsolete)
bbb = PTT Squelch Delay In 10 ms units)
?76

aaa = 30 to 90 MHz squelch level scalar
bbb = Carrier level slope scalar
ccc = Noise level slope scalar
ddd = Squelch level offset
eee = Squelch pot slope scalar
fff = Squelch threshold offset
