Please don't add that functionality to production units. I don't want to pay the engineering cost or material costs that would be required for something that 1% to 5% of the P3 users would use. Make it an optional circuit board that with a relay that breaks the connection that can be purchased and installed by those who want it. 73, Tom, N5GE K3 #806 with SUB RX, PR6, KRC2 and K144XV K3 #1055 with PR6 and XV432 W1, 2 W2's and other small kits QCWA Life Member 35102 [email protected] http://www.n5ge.com http://www.swotrc.net > >Alan, > >Thanks for the answer to my question.
