[Elecraft] Firmware 4.18 APF adjustment using shift control

Wayne has officially yanked 4.18. If SSB problems with 4.17, reload
4.14. Nothing until Lyle gets back.

4.17 alpha testers were going nuts on the APF and likely did little
checking of the TX function change, which apparently had the SSB bug
found in 4.17.  Any problems, reload 4.14.

73, Guy.
