Don AB1PH and Charles VA7CPC,
You are "spot on"...the CTCSS tone is, indeed, injected into the TX path in 1200 mode, but not 9600 mode.? Now I can participate in the aforementioned repeater nets, but have to find another solution for VARA FM WIDE, which wants 9600.
I'll back off my "design flaw" designation and call it a "design oversight" (or what Microsoft would call an "unadvertised feature").
Thanks to all who participated in my quest.
73 and closing down,
Tony KF3AK
