[1000mp] TX inhibit on MP

[Garry Shapiro]

Tonno:

"TX Inhibit" is a misnomer--the function is the opposite.

Pin 8 connects to the collector of the transistor that controls the 
antenna relay. In TX mode, it is LOW. and enables the active state of 
the relay. If you have an amplifier whose TX control is low voltage/low 
current, you can use pin 8 instead of the relay. In this case, you can 
disable the relay and be rid of its clicking. Especially with 
PIN-diode-switched amps, this enables quiet changover. I use this 
arrangement with an Alpha 87A.

> How does it work?. I see BAND DATA jack PIN 8 is TX INHIBIT. Does it mean that I have to connect PIN 8 to Ground to disable TX on the radio? Can this Pin 8 be connected to GND any time during RX or TX and during TX the radio just stops transmitting and goes to RX??
