Default D-STAR Repeater progress


Here's an update on where I am on getting a club repeater up that will be linked to the internet:

  • I've spoken to the local coordination body and received some instructions on how to proceed. It is very difficult to find available frequency pairs in Southern California on 2m or 440.
  • Received permission from the coordinator of the LA Independent Radio Club to add a repeater to their DSTAR system. the LA IRC is a local DSTAR club with several linked repeaters. They also have an internet gateway up, so this allows us to piggy back on their gateway. Because they already have a 440mhz pair coordinated in SoCal for DSTAR, we can use their 440 pair to fill in the valley where I live which does not have good DSTAR coverage.
  • I've been searching for, and made progress on acquiring some inexpensive radios to use as a repeater. I purchased a Motorola based repeater that uses GM300 45 watt radios that is housed in a cabinet with power supply and a Motorola RICK (repeater interface). We don't need the Motorla RICK as that will be replaced with the DSTAR interface. Unfortunately, the seller accidentally shipped me VHF radios instead of UHF radios, so I'm waiting for the correct radios to arrive to exchange.
  • I purchased an inexpensive UHF antenna from ebay: eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices


I will need to get the radios programmed with the correct frequency pair or purchase a cable and locate the software to do it myself. I also still need to purchase the DSTAR board and install the software. I need to figure out what to do for coax, as well.


I'll keep everyone posted as I make progress.

I've received the correct radios and actually successfully programmed them, which was no small feat. I had to get a serial RIB cable, locate the software, and then find a PC with DOS and a real serial port! Last night I also replaced the fan in the repeater case as the existing one's bearings were shot and noisy. The MoenComm Star*Board is on it's way with the firmware already applied.

Here is the remaining to-do list:
  • Finalize the frequency pair
  • Order duplexer / cavity filter
  • Install the software on Windows XP notebook
  • Make interface cables between radios and Star*Board
  • Verify D-Star gateway operating properly
  • Fabricate some type of mast stand-off for the antenna
  • Install Antenna
  • Purchase remote shut-off power strip
I might already have enough coax; I'll have to look in my coax bin to be sure.

Oh yeah, I forgot to say "Thanks" to AcidRod for finding an old laptop with a serial port!

Do you have an estimated cost for all of the materials when finished?

Any word on the antenna? I'm hoping to be D-Staring by this time next week. Do you have an adapter to at least get your HT on the antenna?
