May be worth the additional key relay,, my Kenwood TL 922 quit and I can barely move it let alone try to repair it,,, Not sure what to do wit it but that is another story I keyed another SB200 with an ICOM rig and built a little 5 volt key relay but it used an external wall wart. I may dig up a 9 volt relay and key it using a 9 v battery may pick up a heath SB220 fer 60 bux from a local shouldnt be able to tell the diff 600 v 1200 watts Bob K3DJC
