[ARC5] Waking up Command Receivers

[William Cromwell]

Hi,

I have used R-23 and BC-453 receivers with 24 volt lead-acid batteries 
on the tube heaters and a stack of dollar store 9 volt batteries for 90 
volts B+. With a modest ~100 foot wire no more than 16 feet above ground 
I received NDB and experimental 600 meter and 630 meter amateur stations 
out to about 1500 miles. I have wondered what might come my way if I had 
space for a *real* antenna.

Similar performance with my RAK-7.Sometimes those old radios can pull 
out signals the pretty commercial gear miss.

73,

Bill KU8H
