WTB: KRX3A Sub Receiver
Looking for a KRX3A sub receiver for my K3S. With or without filters is OK. Would also consider a radio that has the sub receiver installed. If a K3, it would need to have the upgraded KSYN3A synthesizer.
I know Elecraft is considering making more of these, but not sure when or if that will happen. If they do, it will still be several months.
