[Elecraft] KX3 Operating Tip: VFO Lock

[Wayne Burdick]

This is the first in a series of operating tips I'll be posting for  
the KX3 that will eventually be incorporated into an FAQ page on our  
website.

If you have tips of your own to share with the list, feel free.

VFO LOCK

Locking the VFO can be useful when operating mobile or portable, or if  
you just want to stay parked on one frequency for a long time and  
don't want to accidentally change it.

The KX3 doesn't have a dedicated VFO lock control. To lock it, hold  
the KHZ switch in for about 3 seconds. You'll hear a beep if switch  
tones are enabled (MENU:SW TONE), and a lock icon will appear above  
the "A" on the LCD.

This locks only VFO A, not VFO B. To lock VFO B, first swap it to VFO  
A (using the A/B switch), then lock, then swap it back. The VFO B lock  
icon will now appear below the "B". You can lock both VFOs if required.

To unlock VFO A, tap RATE or do normal hold of KHZ (about 1/2 second).

If you only want to slow the VFO down a bit rather than lock it, you  
can increase the friction. See page 24 of the current KX3 owner's  
manual. You can also decrease the number of VFO counts per knob  
revolution (see MENU:VFO CTS).
