FT450D, memory tuning and CAT

Interesting event yesterday caught me out. I’d been using the FT450D on 6m FM and had programmed and then selected a memory channel for the local repeater. But when I turned the PC on and ran WSJT-X it gave an error controlling the rig. So I killed WSJT-X and loaded flrig – it too could not control the rig. Then I noticed the rig said M-TUNE (memory tuning). One VFO was still set that way and I presume the program swapped VFOs then lost control and gave the error. I got it out of that and back in to VFO but still no CAT access. Something in the driver (Linux – dunno which driver, probably generic) had got screwed because rebooting the PC cured it all (thinking about it unloading and reloading the driver would probably have worked but by then I’d got into power-cycling mode).

This dual VFO business has caught me out before when I had one set to AM and the other SSB. When WSJT-X loaded it switched VFOs but that remained set to AM. Not the programs fault of course but is something to remember. Not a fault of the rig either, just the operator!
