[ARC5] GRC-109 or RR-2B

[Leslie Smith]

  G'day list readers.
  Can any-one on this list  comment on the general capability of the
  GRC-109, 3 band receiver, covering 3-6, 6-12 and 12-24 MHz.
  This set is also known as RR-2B - a 6 "tube" superhet.  I have a copy
  of the TM.

  It uses the miniature "toobs", including the hard-to-get 1L6.
  The selectivity appears to be broad (9 kHz at 6 dB "down").
  (Seems broad for a set with 2 I.F.'s at 455 kHz)
 Sensitivity is quoted at 5uV.  

  I have not been able to find a spec relating to stability.

  Any info received with appreciation!
