Spekesoftly... I'm still interested in the tones, especially having experience of speechless QGHs in another life. That procedure is usually used by pilots with microphone problems and all one hears is a carrier wave. Do military radios now have the capability to transmit tones when the mic is u/s.
Thanks to those who made kind comments about my retirement.. Last two night duties this weekend and then on part time work for a few months (ie no more nights!) before hanging up my hat.
