Basic Repeater operation ft. Standard RPT21

In this video I kind of go over the basic operation of a repeater. The repeater in this video is a Standard RPT21 @ 10 watts and was pulled from a working environment and is UHF 450MHz wideband. It cannot be used legally on standard commercial frequencies anymore but it can be used on either GMRS or 440MHz Ham frequencies. The 100 watt PA finals were recycled back into service on the new replacement digital narrowband system. I just do not know if it is justifiable or not to order a new set of TCXO's for this radio..
