Hi Wayne & co. I have recently been larking about with an MFJ-1707 in the hope of using it to prevent my newish Wellbrook loop from being sent to an early grave by my KX3.
I've modified the MFJ-1707 to achieve a closed loop solution triggered by the KX3's keyline output, with the KX3's ACC2 input, set to "HI=Inh", driven by an open collector stage shoved into the 1707's Aux contactor output to invert its logic. This solution was preferable to leaving the ACC2 input set to "LO=Inh" as it was fail-safe in the event of the ACC2 plug coming adrift from the KX3, or in fact any other relevant cable doing the nasty. Now the biggest risk to the loop is if I mis-configure the ACC2 IO menu option. Would it be feasible for this menu option to be locked? I don't expect that there is much call for changing it very often. More waffle about the MFJ-1707 mod can be found here: http://www.g0hww.net/2015/02/rx-antenna-switching-with-kx3-wellbrook.html Cheers, 73 Darren, G0HWW ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
