[TowerTalk] Coax Switch

[Patrick Greenlee]

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!!)
