For use with Trxavrb & HOBCAT , after DSP code loaded and AGC has been calibrated,
a 1k resistor should be fitted across pins 2 and 3. (Fit to a spare DB9 plug)
07-12-09 minor tidy up only
~ 8v dc
NOTE: the DPDT switch is a horizontal action switch.
refer to W
WW.ALTRONICS.COM.AU
Cat number S1360 for drawing.
These switches also carried by Farnell.
eg C&K type 7101MD9ABE (check !)
Farnell 957-4786 (check it !)
You can wire in to the PCB any suitable switch if you wish.
