[Milsurplus] PDR-27R

[Patrick Jankowiak]

Just bought one, bought 6 D cells too.

Found all the 'special' meters. One was in the R-392.

Typical emission (beta window shut) at the glass surface was 
about 0.01 to 0.02 mR/Hr, just barely above background as shown 
on meter.

Background was average of about 1 tick per second, over a period 
of about 15 seconds. The reading from the R-392's meter was about 
17 ticks in 10 seconds.

Caveat, unit is not calibrated.. need to send it to KI4U for cal.

Cool.
