Why not have an interface between the station and VHFLOG to automatically change bands?
Done! Many stations have multiple radios and many use transverters with or without transverter switchboxes. Stations may have separate radios for FM or single band stand-alone radios that don`t get switched. I decided to provide computer control in the direction that would get the widest usage, from the computer to the station. A BCD band decoder is connected to the LPT port of the computer, that `switches in` the transverter of choice. When you change bands in VHFLOG, the decoder`s output will also change. This type of switching is used by HF contesters to automatically switch antennas when changing bands. VHFLOG will control all bands with the appropriate decoder/switchbox. Note: Damage can occur if you hot-switch your equipment without proper sequencing. Read this about hot-switching (#4). I tested the band-switching function with the Top Ten Devices band decoder [for a Yaesu rig]. For another more flexible BCD decoder/interface that you can build, see N3FTI`s LPT interface. Q: Why
