The following link lists radios that are approved for use as VHF radio facilities.
Two things to note:
1. The prices listed are higher that we can get them for. For instance, we can get the ICOM F-121 for $251.00
2. The Motorola HT portable radio is not approved as a primary facility radio.
At this point we have the software to support the ICOM F-121 radio. It has 128 Channels and can be programmed for Marine and Auxiliary VHF frequencies. If you ever get a Ham license it can be programmed for that as well. It is a very solidly constructed and meets Mil-STD-810 shock and vibrations specifications. You can get the specifications at:
