Ron,
I have one of these that someone had already modified.. Basically it is a
TL-922, minus a TR relay and a few other parts.. The power setting in the
lower right hand corner is really a band selector switch . Compare it to
the TL922, you will see the similarities. That's about all I can tell
you about it.. Somewhere I understand there is a full set of documents to
convert it..
