Re: [Flexradio] Band data from a Flex-5000 to the Elecraft KPA500 amp?

Lyle: can you confirm that the KPA500 will accept band data and the PTT command on either its PC port (DB-9) or the Xcvr port (DB-9)? That will really answer the question. Thanks! If the KPA500 "RADIO" menu is set to "SERIAL", then it will accept frequency information in Kenwood format over

Re: [Flexradio] Band data from a Flex-5000 to the Elecraft KPA500 amp?

The KPA500 measures its RF input and switches within milliseconds to to the correct band, so if the Flex model you wish to use with it doesn't output band data you'll only lose part of the first dit (if sending CW) or the first syllable (if SSB) or the first... and only when you change bands.
