Vintage RCI-1500 Ranger

Salam, Here another Vintage Radio, probably VHF radio's, but no identification about what band would it be operating, VHF highband or lowband. I never seen this set before, and maybe the programming for this radio still using "EPROM". This technology are too old now, and maybe it will be difficult to programming this radio, also the programmer for this EPROM IC. Here the picture of this radio.Anyone who have info can share the information. Thanks to all, best regards , 73's
