How can I change the tone duration in this mike ? At present it is too short to access IRLP nodes.

Thanks, Dick, W1KSZ

The manual says to put JU-3 in position "A" to defeat the tone timing. Tone will last as long as the button is pushed. JU-3 is near the 3.58 mhz crystal.

L.E.

I found it, had to disembowel the mike entirely. They sure don't want you
changing it too often.
