Intermittent duty base station that has been robbed of parts. No channel elements in the receiver, probably none in the transmitter. No station control card. No high current leads to the final. As noted by earlier posts this is not a unit that will handle long periods of transmission. Also no antenna relay (not that you need one for what you want to do).
Given the number of missing parts I would be very suspicious of the overall condition of the unit.
