G'day Mcrover,

I'd tend to agree they are more likely to be VHF. The FM900 does have a few different versions (VHF Lo, HI and UHF). If it is the VHF version it is of interest for Ham radio operators as it is easily reprogrammed (flash EPROM) to 2meters (144Mhz) also the LROCV have a VHF freq (150 something Mhz) and FM900's are suitlable for that freq also. All tuned up they sell for about 100 to 150 bucks but as mentioned above you have to find someone with the gear to retune it - I can put you in touch with a ham radio club that has done heaps of these and may be of help.

Cheers
