Up for auction is a slightly used Kenwood TKR-850 1 K version (450-480Mhz) Repeater. This repeater will meet the new narrowbanding rules set in place by the FCC. This unit had an easy life and was removed from service due to a digital upgrade. This would make a great replacement/standby or HAM repeater. It has been bench checked to meet factory specs. Included in the auction will be the duplexer and power supply with power cord. It will support battery backup natively. I can program and tune the repeater upon the winning bidders request. There is no implied warranty and I will ship UPS to the lower 48.
