[Collins] Split Mode

[Garey Barrell]

Henry -

This was a common problem back in the 60's.  You were transmitting at 
14.040 MHz.  The problem is that with the S-Line you have to remove the 
cables and replace the 100 ohm dummy load in the transmitter to operate 
split across a bandswitch division.   We used to hear quite a few 
Collins stations calling a DX station on SSB, down at the bottom of the 
CW band!  None of the other brands (Drake, Heath, etc.) had the problem, 
because they had 500 kHz bands.
