There are 2 tuners that work with this radio. The FC-20 and the YT847. The YT847 is better in that it allows a PC connection for CAT control AND tuner funtionality. If you install the FC20, you will loose the ability to control the radio via CAT. Wither of these appear on swap.qth.com or ebail, but you have to be patient.
I see that one is currently listed on Swap.
Thanks
