Hello and greetings QRZ, I would like to ask you why not simply using a DC-DC solid state relay outside a (for example) TL-922A and use a more expensive "soft key" kit to reduce the voltage across the radio key relay? One reason might be the need to power the relay (extra PSU if you radio has already an internal PSU). But is the SS relay introduced delay so bad, even for full QSK? Will SSB be more forgiving? Thank you in advance for your reading and help.
