Yaesu VX-2R memory and battery question
 

I had a few hundred frequencies stored in the memory of my Yaesu VX-2R.
The battery pack died and remained that way for probably a month or
two. Now all of my memory data is gone. Apparently this is volatile
memory.

I store this HT in the refrigerator with a battery installed. This is
where I store all of my batteries. Every six months or so I check the
charge level on all of the batteries.

Whatsmore, it seems that this HT pulls a small amount of current from
the 1 Ah Li-ion battery even when shut off. I say this because none of
my other Li-ion batteries in the refrigerator were anywhere near dead.
The VX-2R battery was dead as a doorknob, so I replaced it.

My queston is, what sort of internal battery maintains the VX-2R memory?
And how long will it last without the main battery? Might my internal
battery now be dead? If the internal battery is also Li-ion then it's
probably best to not store it in the refrigerator if there is a small load.

I'd hate to reprogram this thing only to lose all the data once again.

Thanks for your help.

Gee maybe being cold doesn't help the situation............. Don't let the
battery go dead, USE it once and a while. What did you do buy it to keep it
on ice??

It probably doesn't have an internal battery but more likely a 1F capacitor
or similar, so you will need to keep the batteries charged (for this you
must remove it from the fridge) or the memory cap may go flat in a week or
two. Once the battery pack is charged, it may also take a few days for the
memory cap to fully recharge too.

Couldn't you find a bigger room for your shack?

================================================

You're probably right about the capacitor.

This radio has 1300 memories. Rather than go thru its conventional
programming process again I decided to make an interface cable to my PC
and program it with Commander softwa
