[TenTec] ROCKER POWER SWITCH FOR PARAGON II AND 961 PS

[Bob McGraw - K4TAX]

As a general practice and I believe most would agree,  the power supply 
should come up first and then the radio second.  I have experienced on more 
than one occasion some issues occurred when a "master switch" was employed 
to power up and down the entire station.

Some radios have a simple reset for the microprocessor and I have found 
these do not like a ramp up condition of power at the same time trying to 
load operating parameters. Same for storing data on power down.  Yet more 
secure systems employee a PDI  {power down imminent} circuit that does allow 
for power to go away and yet they still retain the ability to store the last 
used configuration thus no corruption data occurs

I still believe the frequent failure of switches alluded to something out of 
the norm that is taking place.
