[Heath] SB-110A ? SOLVED

[Allen Jones]

The SB-110(A) had a 2M transverter option, the SB-500.  The 500 could be used with either a 28-30 MHz or a 50-54 MHz IF.  Parts for both were included in the kit and the builder would select the required IF during construction.  I built one back in the 70's for use with my SB-102.
