Perhaps not difficult to understand that is does not work easily and does not work as 1990 technology did? I can transmit on either VFO on the 1000D and I would bet that most other radios did also. To be confined to VFO A being the only transmit vfo makes things definitely annoying when trying to operate the radio on two bands. As I said some may not care at all, others do. 73 Merv KH7C
