Re: UEK-3000



Gunther,

I installed two mini coax to the bottom of the PA module, just behind the
TXRX switch, in the RX side. At the back of the 910H you have a little
"window", where i installed two SMA connectors, in and out.

I installed a surplus SMA coax relay, wher at the NC contacts i bypass
the loop, at the NO i have the converter. Ones the converter is powered
up, the Relay takes the converter. This is a really foolproof sollution.
