SR-40/30 Dual Bander and Rocky v1.1
- SR Folks,
Got my SR modified with a switch so I can select either crystal for 40 or
30 meters. Used a sub-mini SPDT toggle switch and soldered the crystals
directly to the switch. The common switch contact connects with a short
lead to the crystal hot side at the board. Actually I'd used a DIP pin for
the connection so I'm plugged into the DIP pin.
The ground ends of the crystals are connected together with a short lead to
DIP pin crystal ground. Along with Rocky v1.1, it's now easy to switch
bands. Works with PowerSDR too of course.
New picture to be posted of the lashup. Haven't grounded the crystals,
BTW, and tapping or touching them doesn't seem to cause any problems.
