Jumpers in RRC Control unit
« on: 2015-10-26, 00:40:09 »
I see on page 207 of the RRC-1258MKII manual there is a diagram of a small jumper board which is in the CONTROL unit.

Quoted text:  "JMP1 should be in place when using Elecraft MH2 Mic and removed when using for example Heil headset."

I am using a HEIL headset and want to remove that jumper.  The diagram of the jumpers is not clear.  JMP1 must be removed but jumpers are color coded but it does not indicate which one is JMP1 .... no labels just color code.

Can any one claify which is jumper JMP1

Frank,

There is a photo on page 22 of the manual. It is also written on the PC board next to the jumper.
