Pictures of the insides of the ID1, RP2V and RP2D at http://www.bosshardradio.com/dstar/23cm_innards or on the dstar_digital photos section.
The RP2D is very similar to the ID-1 except the ID-1 has an additional LSI chip and clock crystal - same radio casting. The RP2V has a fan on the transmitter and none on the receiver. Will take some photos of the antenna and combiner when they arrive. Steve NU5D
