Controlling the VFO A (or B) is easy from software. Just refer the Author to the K3 & KX3 Programmers Reference Manual.
http://www.elecraft.com/manual/K3&KX3%20Pgmrs%20Ref,%20E2.pdf (PS: I'd wish Elecraft would stop using & and spaces in file names. & is a nuisance on the Linux command line, because it normally sends programs into the background ... once can escape them, so it's not really a harm, but still a nuisance. The same for spaces. Those %20 simply look ugly in URLs) Okay, back to topic. Here's an excerpt from that document: FA and FB (VFO A/B Frequency; GET/SET) SET/RSP format: FAxxxxxxxxxxx; or FBxxxxxxxxxxx; where xxxxxxxxxxx is the frequency in Hz. Example: FA00014060000; sets VFO A to 14060 kHz. The Hz digit is ignored if the K3 is not in FINE mode (1-Hz tuning; use SWT49). If the specified frequency is in a different amateur band than the present one, the K3 will change to the new band, and will automatically report the new values of parameters that may have changed 7 . Notes: (1) Band changes typically take 0.5 seconds; all command handling is deferred until this process is complete. (2) If the specified frequency is over 30 MHz and is within a valid transverter band (as specified by the operator using the K3's XVTR menu entries), the K3 will switch to that transverter band. If the specified frequency is outside the range of 500 kHz-30 MHz and 48-54 MHz, the K3 will switch to the amateur band closest to the requested one, and the last-used VFO A and VFO B values for that band will be retrieved. If the VFOs are linked (non-SPLIT), FA also sets VFO B to the same frequency as VFO A. So, basically the software sends SWT49; (note the semicolon) to the K3, and whenever it needs a new VFO A frequency, it sends FA00014060000; (again note the semicolon). Simple, eh?
