Bit Cable Triggers - Multiple Bands Per Pin

It would be nice to be able to trigger on multiple bands per pin.  For example trigger pin 1 for 80 and 30 meters.  This would better accommodate multi band antenna switching using USB relay boards.  Although you could a use frequency range (3.5 - 10) for the above example it would also include 40 and 60 meters which is not desired.

You can use 2 relays on the USB board to do what your asking..  Just parallel the 2 output contacts on each relay, each going to the external outside relay which controls your 80/30 meter antenna.
I have a 80 meter vertical here which also use on 30 meters.

Hi Jim.  Yes, I understand that however I have a 2x6 antenna switch with four antennas.  So I use all 8 relays (4 for each side of antenna switch) to control 160-10 meters.  I have the 20-10 meter triband antenna using one relay on each side and have bit cable pins set for frequency range of 14-29 Mhz.  If the bit cable would allow multi bands per pin then I could make this work with one relay board and be able to work in 30 and 17 meters.  See what I mean ?  Thanks -Joe
