Discussion?  Is an all Digital non-HF QSO – Still a QSO?  Is it OK to store an Analog HF QSO in Digital form – using 1’s and 0’s only – inside an encrypted Logbook of the World file?

Rocky Mountain Ham & Ski Country ARC

by Rocky Mountain Ham – RMHAM.org and KD0MA, K0JEG & N0ECT

3 New RMHAM Linked Sites – Installed in one day, including the updated Colorado Connection.

A crack team of 15 RMHAM team members pulled off another 3 site day interconnecting the RMHAM (front-range) network to Leadville and Vail. This push gets DMR into these areas that have not been covered with DMR until now. We (RMHAM) now cover I-70 nearly contiguously from Genoa through Avon. We installed two, new (digital) microwave hops from our Fairplay site to our Leadville and then over to Vail (Dowd Junction) with three dedicated teams. By noon on September 30, 2017, the DMR and Analog FM system were in place and ready to carry digitized voice traffic – simultaneously over the new Digital Mountain Top Microwave Network.https://i2.wp.com/www.rmham.org/wordpress/wp-content/uploads/2017/10/2017-09-30-Mosquito-Pass-77.jpg

Colorado Connection – Vail – Dowd Junction Repeater – FM Analog  147.345 (+) PL 88.5

DMR – Vail Dowd Junction Repeater – 445.07500 (-) Color Code 7, Time Slot 1 – connects you to RMHAM Front Range Talk Group 700

DMR – Vail Dowd Junction Repeater – 445.07500 (-) Color Code 7 Time Slot 2 – connects you to RMHAM Front Range Talk Group 720

We also added new digital linking for the Colorado Connection and upgraded both the Leadville and Vail (CC) repeaters to new digital hardware! The Colorado Connection still supports FM/Analog Radios, however the new Mountain Top Microwave Linking System – digitizes that FM Analog Voice traffic into TCP/IP – VoIP packets.  This new Digital Microwave Mountain Top Linking ELIMINATES the old Analog FM Link Radio System problems that has plagued SCARC Repeater Backbone for months!https://i2.wp.com/www.rmham.org/wordpress/wp-content/uploads/2017/10/2017-09-30-Mosquito-Pass-40.jpg

Folks from Ski Country ARC from the Vail area assisted the Vail RMHAM team in completing this task. Fairplay team of K0JSC, N2MED, K0GUR got the microwave in and peaked. Leadville team of W0VG, AC0KQ, AE5IT, N0DEV, K0IBM, K7AIH. Vail team was K2AD, WA1JHK, KI0KN, N7CTM with prework by W0KU. Ski Country folks that helped out KD0MA, K0JEG and N0ECT. They installed microwave, power, routers, and all assorted cabling along with doing lots of antenna rework to handle the new configuration.IMG_2436

Problems at Snowmass 146.67

PM – Thursday, August 3rd 2017

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.

146.880 power increased by 20% today.

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.

PA Damage

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 😉

Digital Radio & What’s New from Dayton

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.
