The two photos below are of the new GMSK Modems that will act like a digital repeater controller. They are able to pass D-STAR signals. These two cards will enable the local repeater to connect to other internet based DSTAR Gateways and reflectors. Will W4WWM is in the process of programming the PIC Chip with new Firmware.

When you need to put together a low-cost repeater take a look at Midian Electronics RM-1 Repeater Maker a low cost simplex repeater maker. It offers 2 station ID’s or messages with programmable Morse ID tone frequency and transmit speed. Other features include Morse ID inhibit, hang time, time-out timer, and remote access/disable using DTMF signaling. Add the RM-1 to two radios and you have a repeater.

The PCI Quad Radio Interface is the 4 port PCI radio interface card designed to work with the app_rpt application included in the open source Asterisk PBX. This card has 4 independent channels and can control a combination of 4 repeaters or 4 base stations concurrently and simultaneously. Each channel is has a CTCSS encoder/decoder, level adjustment pots, and an Audio In/Audio Out/COR/PTT interface suitable for interface to your radio system.

RC210 A full-featured controller, capable of independently controlling 3 independent repeaters, 2 full/half duplex links and frequency agile remote base operation (or any combination!) and many more features usually found only in arcom controllers costing hundreds, if not thousands, of dollars more.

RC810  Now you can control up to 8 repeaters, remote bases and link radios with only one controller. The base RC810 is supplied with 4 independently operating Radio Cards, expandable up to 8.

Micro Computer Concepts current line of controllers consist of the following products:

• RC100 is a complete repeater controller with CW ID, timeout timer, COR, tail timer, remote base interface, 15 DTMF-controlled auxiliary outputs, and a complete audio interface with DTMF muting – all programmable with DTMF.
• RC1000 is a complete repeater controller with on board interfacing for the repeater receiver to transmitter, remote base and autopatch. Unlike some controls the RC-1000 contains buffered audio switching and interface allowing for direct connect of the repeater hardware to the control. Pots are provided for adjusting the various audio paths between receiver, transmitter, phone line and remote base. (Note: Pricing for the RC1000 controller is at the bottom of the page.)
• RC-1000V is a complete repeater controller providing all that is needed to connect a receiver and transmitter together to produce a high quality repeater, plus voice identification. With the addition of a phone line, your repeater will have an autopatch.
• Repeaters Micro Computer Concepts has manufactured and marketed repeater controllers for over 12 years. Now it is integrating its controllers with one of the best receiver transmitters to form a ready to plug in repeater on your frequency, tuned and guaranteed. We want to make the repeater installation simple for the repeater owner; a plug and play system. You will need to add duplexer, antenna and 13.8 VDC power supply.

How Does It Work?

TL-NET combines all the features of single-site LTR with our VoIP backbone to provide a multi-site LTR trunking solution. All the benefits of single-site LTR are maintained except now it’s multi-site. All dispatch calls are made using transmission trunking. Setup between sites is extremely fast! In fact, just as fast as handshaking with the local site. Your customers will notice no difference other than their range is extended. View a diagram of the system.

How Do I Use It?

Our system works with standard LTR® capable radios from Icom, Kenwood, Maxon, Motorola, and many others. Use your existing equipment! No special option boards to install, firmware upgrades or special radio programming required. Each site’s Gateway supports a web server that allows you to control and monitor your system from a PC with an internet connection. From a web browser you can validate/invalidate talk groups, adjust TX voice and data levels, enable/disable network access and much more.

What Equipment is Required?

• Each site requires a high-speed internet connection which can be a T1, cable modem, or DSL.
• Each repeater site consists of one TL-NET Gateway and an array of repeaters. The Gateway connects your system to the internet and manages the audio channels to and from the repeaters.
• One TL-NET Server is required to oversee the entire network. The Server can be located anywhere.
• One TL-NET LTR controller is required per repeater. To meet this need we offer two choices: You can go with our CS-540TL-Net Repeater/Controller package, which combines our RF equipment with the TL-NET LTR controller, or you can purchase the TL-NET controller by itself to connect to your own RF equipment.
