Statewide Quarterly Comex

HARVEST MOON Quarterly Statewide COMEX Results

Not too bad folks we are getting better.  We will continue training handling traffic, equipment use and setup, and logging requirements.  One thing we could do is maybe pick an evening and do some training and discussions on Zoom in regards to this.  Thank you so much for being there, your support is appreciated.

Even with bad HF conditions, we were able to pull off the exercise.  HF opened a bit after noon.  We used VHF 2 Meters, 220 MHZ, UHF/70 CM, HF VARA, voice and FM to pass the traffic, using mainly the ICS 213s.  The Comm Center was manned by Don/KL7JFT & Carol/KL2FA.  I had outlying stations in Matsu off Knik Taft/KL4BH(Fire Station 6-2), Kathy/KL7KO in Anchorage, Jim/AL4W in Palmer(Palmer EOC), Brian/KL4A (CAP PIO liaison) at Trail Lakes,  Bridgit/KL4B on Lazy Mountain, Rich/KL7RCS liaison to the Win system in Meadow Lakes, Jameson/KL4TK, roaming in Wasilla.  We has some good training and added to our emergency group.

We connected with Juneau, Kodiak, Tok, North Pole, Palmer, Wasilla, Homer, Soldotna, Kenai, Eagle River, Chugiak and Anchorage.  We had a few check ins on 3920 and 2 check ins on DMR TG 3102.  Dave/KL7EB, the Section Manager checked in on 147.30 for an exercise update.  We had a total of 9 check ins on 2 Meter, 5 check ins on HF, and 2 on DMR.

Traffic handled by KL7JFU Comm Center

194 Winlink messages, incoming, originated, outgoing, relays and acknowledgments. We ran 3 Winlink Stations, 1 2 meter, 1 220, and one HF.  The Comm center was ran off Battery and Generator power for the entire exercise.  We monitored 3 local repeaters and 3920 on HF and TG 3102 on DMR Repeater.  We also had the KL7JFT-10 RMS up, the KL7JFT-5 APRS IGATE up, and the Eagle Packet network from Matsu to Homer up.  Received an additional 7 msgs after close of exercise for a total of 201.

Message templates received and work quite well were the ICS 213, County Status Report, Winlink Check in report and Weather report.  In Matsu we like to have our stations submit the last 3 so we know their status and condition and who and what we have at the remote locations.  Stations without Winlink do this with a paper forms they carry in their go boxes as well has message blanks.


Items noted during the exercise.  Stations need to know their lat long in order to plot their positions more accurately.  Stations need to know how to get the weather from their nearest airport or NOAA and thru Winlink.  If all else fails, this is where the weather spotter training comes in on our SKYWARN Program.  Also folks need to keep a Comm Log and the ICS 214, which is their time sheet for the operation.  Our upcoming training will including logging and msg ops.





Exercise Scenario:  Hunting season is upon us with hunters all around the central part of the state are the field and isolated.  Weather has changed and severe blizzards are occurring, weather has closed in and planes are grounded.  Winds up to  50 MPH.  There is a lost musher in Anaktuvuk Pass area.  Hypothermia is a major concern and planned pickup of hunters requiring air extraction can not be accomplished.  Fairbanks Memorial Hospital is the nearest facility and Covid procedures are in affect.  The SEOC is coordinating rescue efforts with the Air National Guard.  Report any information that will be helpful in rescue of the hunters.



Summer Solstice Qtry State Wide Comex (Completed)

20 June, we completed our Quarterly Alaska Comex, from 0900-1400.  We received, sent and originated msg traffic by Winlink and VHF/FM voice.  Bushmaster Operations cleared all traffic. Had 17 hams check into the Phone net 5 on HF & 17 on the local repeaters & 2 on DMR.  The exercise was support of the borough and forestry fire suppression teams. All traffic was handled on Winlink RMS and P2P, using VARA, Pactor, Packet, & using the Eagle Packet Network (145.01) down to Homer and places in between.  The RMS stations were KL7EDK, KL7GRM, WL7CVG-10 & KL7JFT-10 on various frequencies. We generated Health & Welfare, County Status & Windshield reports & Sitreps.  We had request for equipment, rescue, both animal and human. We used ICS213s, text msgs. Our long haul was P2P to AG6SV/Ken the Saturn Communications Coordinator. The DMR network used the AK TG 3102 thru our local repeaters. We had hams from Tok, Big Delta, Northpole, Fairbanks, Anchorage, Sterling, Eagle River and throughout the Matsu Valley. A big thank you to all the hams who participated.  Start studying and practicing for next Quarter.



DMR Radios

OK what is DMR Radio.

Digital mobile radio (DMR) is a limited open digital mobile radio standard defined in the European Telecommunications Standards Institute (ETSI) Standard TS 102 361 parts 1–4[1] and used in commercial products around the world. DMR, along with P25 phase II and NXDN are the main competitor technologies in achieving 6.25 kHz equivalent bandwidth using the proprietary AMBE+2 vocoder. DMR and P25 II both use two-slot TDMA in a 12.5 kHz channel, while NXDN uses discrete 6.25 kHz channels using frequency division and TETRA uses a four-slot TDMA in a 25 kHz channel.

DMR was designed with three tiers. DMR tiers I and II (conventional) were first published in 2005, and DMR III (Trunked version) was published in 2012, with manufacturers producing products within a few years of each publication.

The primary goal of the standard is to specify a digital system with low complexity, low cost and interoperability across brands, so radio communications purchasers are not locked into a proprietary solution. In practice, given the current limited scope of the DMR standard, many vendors have introduced proprietary features that make their product offerings non-interoperable with other brands.

The ham versions of the Anytone, TYT,Retevis, BTECH, Ailunce, Yaesu and Alinco and a few other brands are Tier I and II.  And both Analog and Digital. The ALMR radios that the state is using and some municipalities are Tier III.

Some of the radio are Type 90 approved and work for ham also.  Prices vary 100-300 dollars.  There are some mobile version out there as well that go for 300-600 dollars.

My brand is the Anytone from Bridgecom.  This training and support they provide is top notch and no question goes unanswered.  They have several videos out on U-Tube and they have training courses at Bridgecom to take you thru the radios, programing and use.

Building your first code plug is a little daunting but their videos and support sites get you thru it, plus you can get with a buddy and share.

We currently have 4 Repeaters operational in Alaska, South Anchorage, Homer, Fairbanks and Wasilla. We organize or various groups of contacts into groups called Talkgroups and have one for Alaska, but there are several that include the lower 48 and the world.

These radios can be used on RF or thru internet/WiFi and cell phone hotspot connections.  We are experimenting in the Valley using them simplex and repeater coverage areas to see how they compare to standard Analog simplex and repeaters.

This is just the beginning.  Folks who are interested and/or are working this mode, lets put out heads together and see if we can getting going.



We have mentioned the basics requirements at our meetings and news letters for folks interested in Emergency Communications.

It was brought to my attention that it makes sense to complete them in the following order, not numerical order…..

“The recommendation is that folks begin with ISC 700 then 800 then 100 then 200 and finally 144.”






Please let me know if any of you want a classroom setting so I can schedule that with our trainer

Please send a copy of our completion certificate to Don Bush/KL7JFT MATSU DEC, to put in your training file.
