I forgot to mention it does have the internal antenna tuner.

I have a Flex Radio 6400 for sale.  I bought it in late 2022 with the intention of operating it as a remote station.  I quickly discovered the complexity of this radio and my feeble mind were not compatible.  I configured the radio and the SmartSDR software and operated it for about 250 hours over a 3 month period before packing it back in its shipping box.  It's been on a shelf since then.  I'm offering to ADXA members the Flex-6400 with microphone, power cable, and FlexControl by K6TD (an optional USB controller) for $2000.  That is over $500 less than what I paid.  It will be available for pickup at the Arkansas River Valley Hamfest this Saturday.  Contact me if interested.
