Actually, I wouldn't be too concerned about the condition of the rest of the station. As stated earlier, the channel elements are often removed to prevent operation on the previous user's channel. Not a big deal. The cards are often kept as spares, particularly if the station was disposed of through a repair shop. The missing PA power leads are a bit unusual but, at most, five minutes to replace them. If you want to make a repeater, you don't need an antenna relay but they can be found too, if needed. I wish I had a dollar for every ham repeater that is made from converted mobiles, these are ALL "intermittent duty" transmitters. With reduced power and a cooling fan (mainly for peace of mind) this station will be more reliable than 80% of the so called continuous duty ham gear out there. I'd take that station anyday in preference to a "Kensu" desktop "repeater". The receiver is easily converted with a "recoiled" RF front end available very reasonably. Your biggest challenge is going to be that HIGH split transmitter. Tom
