I've got a 580 Delta and you'd have to drop an anvil on it to change its
frequency. Unless your cat plays with the tuning knob, it'll stay put, I
think. You could always remove the tuning knob to keep the cat from
diddling with it.

Subject: Re: [TenTec] Outboard VFO for Delta 580
I guess that's why mine doesn't have one... hi. I don't know what
different kind of features could be added to keep the frequency from
changing. I expect a very rudimentary one could be anything that kept
the knob from turning. I've been a ham for 40 years but my experience
with different rigs is limited, so I don't know what different rigs use.
My Jupiter has a dandy frequency lock, but my Delta could move if the
table is bumped or the rig is moved. I need to remove that possibility
because I want to use it on HF packet where it will be on the air
without supervision for hours at a time...don't want it wandering off if
the cat jumps up there. I can add a crystal control to the VFO input
but just wondered if the VFO had some protection against the frequency
changing as then I wouldn't be limited to one frequency.

Hi Mark,
I don't believe I've ever heard of a "frequency lock" on a rig with a
PTO.
What would that be? A screw through the tuning knob to keep it from
moving?
