[ARC5] Spot switch for the ARC-5 transmitter

[JAMES FALLS]

I spot my BC-375 / BC-348 that way. Installed a switch in the 348 power cable from the 375.  Zero beat to the NCS, then tune the 375 to it. 

My TCS pair do that with a switch position on the transmitter. Not a “hunt and pounce” contest setup, but great for nets and QSOs.
