Signal/One CX7A
S/N 71-219

This Signal/One is one of the California radios.  It has the "B" power supply board.  The keyer/counter board is the nixie tube version.  I got this radio in March 2005.  It was acquired with my Alpha 77Sx.  As with many of these radios it had developed a problem with the BFO board.  The 8.8 MHz oscillator is off frequency.  4/20/05 - problem solved.  Bad xtal on the BFO board.  Replacing this brought the entire radio back to proper operation.
