Hello, all.

What I'm going to share here may not be big news to some, but for those like 
me who never had this problem, it is a bit disconcerting.

Tonight, I decided to fire up and get re-acquainted with my TS590, since I 
probably hadn't even turned it on for a month and a half.  I had taken some 
SWR and output power readings using the rig's  internal meter, and 
everything looked great, until I tried getting on the air.

Even if I was on a resonant or near-resonant frequency for one of my 
antennas, the rig's auto-tuner would not tune.

I played around for quite a while, trying to figure out what was wrong, and 
then, I decided to swallow my pride, and ask the sighted XYL for help.

It turns out that I inadvertently had activated the DRV function.  This 
happens when you press the meter function button down too long.  The meter 
switch is one of the few buttons that doesn't talk on the rig, so it's very 
easy to make this mistake.  Once the meter switch  button was re-set to 
normal, everything was fine again.

Does anyone know what the DRV function is, and has anyone ever used it?

Just curious.
