I had a Paragon several years ago, and found the memory back up to be
nearly useless. I called Ten Tec and they said you need to leave the power
supply on!
Naturally, I told them that was no good.

What I did, was go by a battery holder for 8 AA nicads and used them
instead of the 9volt nicad. Next I got an LM317 and set it up has a
constant current source. If I remember correctly at 50ma. The input
connected to +13.8 and the output connected thru a diode to the batteries.
I believe the diode was already in the circuit from Ten Tec, but don't
remember for sure. 
This would allow the radio to keep its memories for a few weeks. At least
it was good enough for my operation.

Hope this helps.
