Wayne, It is a good idea ... particularly if you get closures on any of the inputs that would force transmit when first powering up. In particular,
you would want to look for PTT on mic, PTT/RCA, PTT/ACC, or RTS) and CW inputs on DTR, key, left paddle or right paddle. Yaesu does a similar thing in most of their recent radios. If the PTT or Key is active at power up, the radio will not transmit until the PTT/Key has first opened (reset). The only thing is that they do not display an error message ... 73, ...
