[TenTec] Paragon memories

[Jim Bull]

Both of my Paragons have the rechargeable battery mod and I use a 9 Volt
Nickel Metal Hydride rechargeable battery.  Works good-lasts a long time.
On the radios with the recharging mod, there is a "constant" 13+ volts 
feeding the rechargeable battery. If you use a standard 9 volt 
(non-rechargable), it will drain in just a few days and will actually 
swell/explode if the radio has the recharging circuit.  The one thing 
that I have found is that the 961/962 power supply must remain plugged 
into the AC circuit (need not be turned on) to continue to keep the 
battery up to correct voltage.

Regarding the Giehl Chip, it is still available:

You will just need to tell Jack what TT ROM chip is currently in the 
radio, i.e., 3.8/4.0/etc.

73's
