Analog Repeaters

  • W0CFI: 448.675 -5MHz offset 100Hz tone. Wide area coverage on Squaw Mountain.
  • K0PRA: 449.425 -5MHz offset 100Hz tone. Local coverage in Parker on the “water tower”.

AllStar Link

What’s AllStar Link? In simplest terms, it’s a way to connect analog repeaters and/or radios over the Internet. The mechanics are actually quite similar to the DMR/DSTAR/C4FM digital modes you’re probably already familiar with. The key difference is, the digitizing of your voice doesn’t happen inside your radio, it happens inside an AllStar node – a bit of hardware connected between the repeater and the Internet. Another difference is, unlike the “talkgroups” / “reflectors” / “rooms” we use in digital modes, in AllStar Link, every node itself is connectable. In other words, every AllStar Link node is a talkgroup!

Our AllStar Link system runs a “hub and spoke” model where spokes may be permanent links to nodes deployed on our own analog repeaters or semi-permanent nodes deployed by hams to provide analog coverage to their own neighborhoods. The PRA AllStar hub fully supports inbound and outbound linking world-wide. PRA members can manage the PRA hub links via the PRA AllStar Hub page.

  • K0PRA Elizabeth DMR: 447.300 -5MHz offset. Color Code 1.Time slot 1 linked to BM 310759. Time slot 2 linked to BM 310844.
  • K0PRA Franktown DSTAR: 446.850 -5MHz offset ICOM DStar Stack. Default link is Colorado Mega XRF223-B.
  • K0PRA Parker Wires-X / C4FM Digital: 447.225 -5Mhz offset. Default link to Colorado Mega linked room 40895.

Experimental Machines

  • N0KEG Parker VHF: 147.315 +600KHz offset. Pi-Star based MMDVM repeater running dual mode DStar (primary) and DMR (secondary). Default link is to Colorado Mega DCS376-D. DMR is linked into Brandmeister, no static talk groups assigned.
  • N0KEG Parker UHF: 449.275 -5MHz offset. Time slot 1 linked directly to 310759. Time slot 2 linked directly 310844 . This repeater is NOT on Brandmeister.
  • N0KEG Lone Tree UHF: 447.075 -5Mhz offset. Time slot 1 linked to BM 310759. Time slot 2 linked to BM 310844. This repeater will be moved off of Brandmeister in the near future.

Please see the dashboard links below for more information on these digital machines.

Parker Local Transcoder Network (TG 310844 / 720-C / 376-C)

Access to the Parker Local system is available via DMR or DSTAR.

You can access the Parker Local system via DMR on XLX720-C in DMRGateway mode from your hotspot. This talk group is statically linked to time slot 2 across the K0PRA DMR repeaters.

Brandmeister DMR talk group 310844 is another way to get in, however, there are stability issues with Brandmeister links.

You can access the Parker Local system via DSTAR on DCS720-C or DCS-376-C. Feel free to link the Franktown K0PRA DSTAR machine to DCS720-C for access to the Parker Local system.

The Parker N0KEG DSTAR machine prefers DCS376-C for Parker Local access.

Colorado Mega Reflector (TG 310759 XRF223-B / 720-D / 376-D)

Access the Colorado Mega system via DMR, DSTAR, C4FM or Wires-X.

You can access the Colorado Mega system via DMR on XLX720-D in DMRGateway mode from your hotspot. This talk group is statically linked to time slot 1 across the K0PRA DMR repeaters.

Brandmeister DMR talk group 310759 is another way to get in, however, there are stability issues with Brandmeister links.

DSTAR capable clients should link through XRF223-B. Alternatively you can link to DCS720-D or DCS376-D.

Wires-X repeater, node and PDN users – Link your device to the Colorado Mega 40895 Wires-X room.

Yaesu C4FM radio users via hotspot (Pi-Star, Openspot, etc…) – Use YSF Reflector 23160.

Colorado Mega Reflector Tips and Tricks:

  • Let the system drop – At any point in time there are no fewer than 40 devices linked together. Some on the internet, some via RF. The latencies amongst all of these links can vary from 10s or 100s of milliseconds and in some cases a full second or two. After hearing a transmission, don’t quick key the system like you would on a single analog FM machine. All of the devices involved need to completely drop when crossing modes. If all the links don’t get a chance to drop, you may only re-key half the system or none of it at all. Be patient and let the system drop for a full 1 to 2 seconds before replying to a QSO or during busy times like net check-ins.
  • Let the system come up – The opposite is also true. The system needs ample time to key up 3 different digital modes on dozens of machines. After the key-up command makes it to a particular device, the RF transmitter on these machines need a few hundred milliseconds to settle down and make a clean transmission. So when keying up the system, key the mic and count 1-Mississippi in your head before actually speaking. This will prevent the 1st part of your transmission from being cut off.
  • Use ITU standard phonetics during check in – Please use standard phonetics when checking into nets on a multimode digital system.
  • Brandmeister – The vast majority of the time, traffic between the Colorado Mega system and Brandmeister will go through Master Server 3103. In order to keep points of failure to a minimum, if coming through Brandmeister connect your hotspot to 3103. There are known performance issues with the Brandmeister links, whenever possible link directly into our system.
  • Register a DMR ID – Even if you are using a mode other than DMR, the DMR ID database is used for call sign lookups on the dashboards and call routing. If you do not have a DMR ID, your callsign will not be visible to most of the system. It’s free and easy to register a DMR ID to be linked to your call sign.
