I do think they have to have the same callsign, just different designators
('A', 'B', 'C', 'D', etc.) like "WS8TAR A", "WS8TAR B", "WS8TAR C", "WS8TAR
D" ... the use of A for 23 cm, B for 70cm, and C for 2m is only a
convention, nothing in the protocol or configuration requires it.
Just like most US band plans reserve Simplex frequencies in the repeater
segments, its only convention, technologically, the 200 kHz. between
146.4-146.6 Mhz. and 147.4 and 147.6 Mhz. could make a nice set of 16 D-STAR
repeater pairs at 12.5 kHz. spacing and 1 MHz. split, if the coordinating
bodies and the general ham population agreed. They would have to shift just
a bit because Icom didn't put 6.25kHz. steps in the IC-2200, but could still
be 15 kHz. away from the adjacent analog FM repeater signal. Even preserving
the 146.52 Analog FM calling frequency you can get 15 pairs. (Maybe making
147.52 the DSTAR calling)
146.4050 147.4050 DSTAR PAIR
146.4175 147.4175 DSTAR PAIR
146.4300 147.4300 DSTAR PAIR
146.4425 147.4425 DSTAR PAIR
146.4550 147.4550 DSTAR PAIR
146.4675 147.4675 DSTAR PAIR
146.4800 147.4800 DSTAR PAIR
146.4925 147.4925 DSTAR PAIR
146.5050 147.5050 DSTAR PAIR
146.5200 147.5200 FM Analog Simplex Calling
146.5350 147.5350 DSTAR PAIR
146.5475 147.5475 DSTAR PAIR
146.5600 147.5600 DSTAR PAIR
146.5725 147.5725 DSTAR PAIR
146.5850 147.5850 DSTAR PAIR
146.5975 147.5975 DSTAR PAIR
I don't see it happening, but its interesting what a little cooperation and
creativity could do.
