The Arcom RC210 is a true 3‑port repeater controller that is available as a kit or already assembled. Each port has its own timeout and hang (carrier delay) timers, courtesy tone, ID's and dedicated DTMF decoder. Each port can be intertied to any other port. Each port can be configured as a repeater, a remote base, or a half or full duplex link port. Options include the RAD Audio Delay Board (eliminates squelch crashes and DTMF blips) and the AP1 Intelligent Autopatch Board (which doesn't tie up a radio port).

The Arcom RC-810 is a true 8-port repeater controller that was introduced at Dayton 2006.

More than 3 ports? By Ken Arck AH6LE of Arcom Communications. 18 kB PDF
This factory appliications note shows to connect a wide variety of half-duplex sources to the RC210 without using a port. While the Auxiliary Audio Inputs were originally designed to allow connection of a WWV receiver or weather receiver, this writeup shows how you can use those or other sources along with Alarm Inputs to simulate up to 3 additional ports.

The only limitation on these "new" ports is that the audio source has to provide its own squelch or audio muting (because the aux audio ports are on all the time, they are not switched on and off). The most common use of these additional ports are AllStar, IRLP or EchoLink nodes or a weather receiver, a control receiver or a half-duplex link or remote base radio.

note that some weather receivers require you to push a reset button to mute the audio where others mute themselves on receipt of the End-Of-Message code in the broadcast. Personally, I've seen some broadcasts contain the EOM, and others from the same NOAA weather transmitter do not have it. I'd wire an RC-210 digital output drive the coil of a reed relay, and connect the contacts of that relay across the reset button of the weather receiver "just in case".
(anybody want to do an article on that?

Note that the COS and CTCSS inputs of the three "real" ports of the RC-210 can handle up to 15vDC, but the logic (alarm) inputs that are used on the "new" ports MUST NEVER exceed 5vDC. The same is true of the A/D inputs.

Connecting a Reecom R-1630C Weather Radio to the RC-210 repeater controller By Randy Elliott VE3JPU

Programming the RC-210 controller for a Reecom R-1630C Weather Radio By Randy Elliott VE3JPU

Repeater-builder received an email from Ken:
As we discussed on the phone, here is some info for the RB website:

I now have the capability to give Kenwood TKR repeaters (750/751/850/851) the following:

1) 120 degree phase shift for reverse burst
2) Turning off pre-emphasis on xmtr audio, allowing flat audio through the system for situations that use an external controller. This flat audio IS limited by the TKR's internal limiter/BP filter negating the need for any external limiting and filtering.

#1 is accomplished by the use of custom template data files for each of the above radios. Unfortunately Kenwood won't allow the sharing of those templates HOWEVER they have authorized us to provide complete data files (with all the customer freqs, etc) as we deem fit.
