If you don't find a control box you can make one easily. It is just powered by a small wall wart (or other supply.) It is the equivalent of a single pole 5 throw switch. It is a rotary wafer switch with 5 positions and is probably break before make contacts. I haven't opened mine up so it is always possible it is a two pole switch with one pole switching the indicator LED's internally and the other pole sending power out one of the 5 output wires (with the 6th wire as common.) If you could maintain discipline and not mess up you could use 5 single pole single throw switches to switch the relays in the remote box. You'd just have to remember to switch off the current energized circuit before switching on the next one. One on at a time only please. The indicator lights are just LED's with a series current limiting resistor so they don't burn out or shine too brightly. I'm kind of jammed up time wise right how but if you want me to draw a schematic contact me via PM and I will try to get it done ASAP. I'm good in QRZ.

I spent the day with my trencher digging out for a concrete pour of a tower base on Fri if at all possible as I have a flying trip to the left coast and will be out there in SOCAL for a week before team driving back and then entertaining a house guest and then and then... Need to get the base poured to start the count down clock ticking... Standard concrete mix cures to 90% of its final strength in 28 days.I have a second house guest due in May. He is a mechanical engineer (masters degree from UCLA) with 30 + years hands on experience and is my consultant and sanity checker for my designs. Got a good start on the hole and got all the rebar cut and the stirrups made.

Looking for a control box as a replacement for my Ameritron RCS-8V. Remote
unit OK.

Got one laying around not being used?

(Using this on my LM354 tower so related to Tower Talk!!)
