Appears we have had a hardware failure on the link radio, or the controller up at the 146.67Mhz Aspen/Snowmass Repeater site.
I did some troubleshooting today and determined that it was not in any of the controller configuration that I could identify, so the most likely problem is hardware.
Previously the link was transmitting into the UHF hub, but not receiving. Rather than have a one way link operating that can create all sorts of havoc, I’ve turned off the link at Snowmass until we can make a site visit and attempt to make a repair.
Stay tuned. Will probably be a couple of weeks before I’m able to make the site visit.

So I planned on making a recon trip to see how far the road was open up Sunlight on the way home this afternoon. Surprised that it was in really good shape and was able to drive to within 30 feet of the gate (still 1/4 mile from the SCARC radio site). Since it was 70°, Sunny, and I had my hiking boots with me, I did the hike in, but wasn’t able to carry much test gear with me – just a watt meter.
Was able to determine that 88 was only putting 10 watts out of the duplexer to the antenna. No reflected power on the antenna. Checked at the radio, and it was putting out 20 watts. No amplification from the Power Amplifier.
Just looking through the vents revealed some serious heat, a small copper tab that looks like it’s designed to dissipate heat was out of place. Probably indicating that we heated up the board enough to flow the solder. Good news is that there was no obvious damage to the board.
You can see that the upper one is horizontal, the circled one is at an angle.
I was able to carry the PA down with me, and have it here in Glenwood Springs. I’ll be calling the manufacturer Monday and making arrangements to get it repaired. Hopefully we will be able to get a quick turn around.
Meanwhile removing the PA and a jumper brought the power out of the Duplexer to the Antenna up to 12 Watts. Enjoy that extra power 😉
Seems like the word didn’t get around much, but the Annual Tailgate in Delta is Tomorrow. Starts at 8 AM at Confluence Park in Delta (to the west of City Market) Map is accessible from the link – http://www.arrl.org/hamfests/montrose-arc-tailgate-party-1
They usually have coffee and donuts available, usually runs until noon, though the crowd will probably be pretty thin by then. Free admission, tables for sale items are $5.
See you there. Chuck n0nhj
Some arial pictures from the club picnic at Pat’s place. Glad people enjoyed my demo and got a chance to try their hand at piloting the aircraft. Next time maybe I’ll have a few more batteries…
The Days of the Digital Radio “Tower of Babel” are coming to an end.
The different Digital Modes promoted by different Radio Vendors are starting to “Converge” via new Digital HUBS and Digital Servers.
Result? DSTAR folks can talk to C4FM/Yaesu using their native vendor specific Radio, DMR Radios interoperate here too. The ever popular Digital HT – the MD380 was selling for $75.00ea at Dayton. Digital Mobile interoperability is improving too because of the availability of WiFi while Mobile due to today’s SmartPhones.
Below is a great summary – of what’s going on in the Digital Radio World – from Dayton last week.
Glad everyone enjoyed my presentation. Here are the pictures that Gerry, Brian, Pete and I took while flying. Word around the club is that Debbie N0LDB is going to get one for her birthday this year!
