To improve mean-time-to-QRO and avoid tape on the front of my amplifier and
tuner, I added support for "frequency-dependent devices" to my transceiver
control software. I recorded the setting-vs-frequency info for each device
in a file; the software uses this data to display the proper settings in a
small window, tracking smoothly with tranceiver frequency. See
http://www.ambersoft.com/Amateur_Radio/DXLab_Control.jpg for a screenshot.
