Trent I found that the Arduino 8X1 relay board is a magnificent solution
to the problems I was having here. The problem I was having using the
Ameritron RCS-12 Antenna Switch, which is driven by my Icom IC-7410 BCD
output or switched in the shack manually,
In my situation the Ameritron RCS 12 problem was not solved by the
factory, A simple design change in the circuit cutting off the pass
transistors would have worked. The pass transistors controlling the
voltage to the DXE 8X1 box at the antenna were not sufficiently biased
off thus allowing some voltage to get to the wrong relay. This cause the
relay to misfire at times and the SWR protection circuit to shut down
the amp. Here comes the Arduino board which solved everything. The
Arduino 8X1 has 8 relays and is driven by a high of 5 volts obtained
from the Aux socket on the RCS-12 for each band selection. The Arduino
8X1 even has status LEDS for each relay activated and was only $12.95 on
eBay. It has now screw down headers and on all the relay switched
terminals.
Eventually more of this development will find its way into amateur radio
including graphic display for remote operation. But this Arduinos stuff
is paving the way, BTW I also use them to control a Six Pac and filters
for SO2R contest work here

Having noticed a new change of tack by manufacturers to IP based antenna
selection and a plethora of IP/ Relay driven devices reasonably priced on
Ebay -
Has anyone had any success using these items (EBAY) to control the likes
of Six Packs or switched bandpass filters - and integrating with N1MM or
the like ?

Please note I no longer use the WIA email address where possible owing to
it blocking emails from sites such as VK Logger and ARRL.
