EchoLink and the MARC Repeater – Advanced Topics – 15 Feb 2024

Jan (KD7ZWV) introduced the MARC repeater and talked about the need to provide some type of wide area connectivity into the repeater for MARC members (and others).  He covers repeater linking, both RF and Internet based, and moves on to the solution that MARC is exploring, EchoLink.  EchoLink is introduced and we discuss how to get an EchoLink account, including getting your license validated. Finally, EchoLink configuration is covered.  Jeff (KL7KVG) continues with a discussion of the EchoLink for Android application and then talks about the EchoLink node that he has built as a proof of concept for the MARC repeater.  Finally, we observe a demo of the EchoLink software connecting to the MARC repeater using the node Jeff built, which was on display in the meeting room.

Additional notes:

  1. This project is NOT complete... Jeff detailed a few things that we still want to do, including
    1. Registering N7MRY-R as an EchoLink node
    2. Installing the node at a location other than Jeff's dining room table
    3. Not hogging up Jeff's portable computer (dedicating some hardware to the node)
    4. Tweaking and adjusting parameters to improve the functionality of the node
    5. Configuring outbound connectivity from the node (i.e. DTMF control)
    6. and whatever else we think it needs to be a solid addition to MARC's repeater setup
  2. We had some previous classes that covered repeater linking, including IRLP and EchoLink
    1. April 8th, 2021, Radio Linking via Internet IRLP and EchoLink
    2. October 14th, 2021, we had a joint meeting with the Taylorsville club on IRLP and EchoLink presented by Doug (AD7LO).  This meeting was carried on the Taylorsville Zoom and we were unable to record it.  I believe the slides are the same as recently presented to the Taylorsville club and can be found here:  Doug's IRLP and EchoLink Slide Deck
  3. As mentioned during the meeting, our prototype is not online all of the time... Jeff will be facilitating experimentation with it by bringing the node up about an hour before our Sunday net and leaving it up for about an hour afterwards.  If you want to experiment with EchoLink and the MARC repeater, this will be an excellent opportunity for you to try it out.  Get the software installed, get your EchoLink account set up and validated, and be ready to try it out this Sunday beginning around 7:00 PM until about 9:30 PM.

The Farnsworth .62 Repeater – General Meeting with UARC – 8 FEB 2024

The four of us from MARC who attended the UARC meeting tonight learned a lot about the "Farnsworth" .62 repeater.  Clint (KA7OEI), the repeater manager for UARC, started with a brief history of the .62 machine, including some unique aspects related to its installation at the Fox 13 transmitter site.  He then delved into ways to extend the coverage of a repeater by linking multiple repeaters together.  Of course, the best example of this in Utah is the Intermountain Intertie, a linked repeater system that covers most of the state, with branches into Idaho, Montana, Nevada, and Arizona.  The drawback to such a system is that each repeater needs to be on a different frequency.  This led to a discussion of the .62's setup, with a master repeater on Farnsworth peak and a secondary repeater on Scott's.  These two repeaters operate on the same frequency, using only one frequency pair for extremely wide coverage.

UARC has posted the recording of the meeting on their Youtube channel, and I'll include it here.  If you're curious how this system works, check it out.  At the end of the presentation, there was also some discussion about direction finding and how to deal with abusive use of the amateur frequencies, which was also quite interesting and may be the subject of a future UARC talk.

Advanced Topics for 2024 – 11 Jan 2024

Last night we met to discuss what we want to do for the Advanced Topics classes in 2024.  As you may (or may not) know, MARC has a so-called "Advanced Topics" class on the second Thursday of each month.  These classes are intended to reflect more advanced and/or esoteric topics.  Historically, I've presented something about amateur radio that I found interesting... a technology or subject that is related to amateur radio and is more involved than just chatting on the repeaters (or even via HF).

For 2024, I want to continue this model, but extend it.  I want to spend several classes on each topic, starting with an introduction and background, but moving to a hands on session where we (the club members) actually DO something with it.  This may include things like configuring equipment, building antennas, etc. and ALSO includes taking that configured equipment, antennas, etc. out and actually USING it.  I want the Advanced Topics classes in 2024 to be more about DOING than just being SHOWN something.

To this end, I suggested three sample topics that I am interested in and that I thought would fit into this model fairly well.  The topics I put forward were Winlink, 10m operations, and AREDN.

I know we've done some classes on Winlink before, and we participated in the multi-club Winlink Workshop last year that was very well attended.  I want to do that one better... starting with an overview and background on Winlink one month, then having a mini-workshop the following month where we actually get our equipment configured and working, and finishing it up with us taking our gear out and actually using it to send messages, process forms, etc.

For 10m, I suggested a similar model, but concentrating on what you need to get on 10m.  That basically includes a radio and an antenna, so one class session could be on actually building (or modifying existing CB) antennas.  This series would culminate with us getting onto 10m and participating in Paul's 10m weekly net.

And for AREDN, the club has a bunch of hardware that was donated by a ham who was moving.  We could spend a session learning about it, another session configuring the hardware, and a final session hauling the gear out into the real world and setting it up to see how we can make it work.  I think we may be able to leverage UVARC's people as they have been using AREDN effectively in Utah County.

After presenting these three topics, I opened it up for discussion from the group about other topics that may be of interest.  We came up with another fifteen (!) possible subjects.  I'm going to do a little research on these, since many of them will require some level of investment in hardware and/or software (antenna parts, while often inexpensive, are not free).  Once I have some idea of what's involved, I'll put together a little survey for people to register their interest.  If you have an idea for another topic that isn't on this list, please let me know and I'll add it.

Without further ado, here is the list of potential topics for MARC Advanced Topics classes for 2024 (and likely beyond):

  1. Winlink
  2. 10m operations
  3. AREDN
  4. Software defined radio (both receive AND transmit, and what to do with the things you receive)
  5. NVIS (Near Vertical Incident Skywave antennas, how they work, building them, using them)
  6. mounting antennas (mobile and fixed base)
  7. SKYWARN/weather monitoring (to include CWOP and building your own weather station, weather telemetry on APRS, etc.)
  8. APRS in depth (using APRS in events, digipeaters, building a digipeater, getting club assets on APRS as objects)
  9. Digital Voice modes (this we broke out into three sub-topics since there is probably enough in each to spend at least a couple of classes on)
    1. D-star
    2. DMR
    3. YSF
  10. radio astronomy
  11. high altitude ballooning (build a balloon and launch it!)
  12. EME (Earth-Moon-Earth, from what do we need to actually do it, to let's actually do it!)
  13. satellite operations (what satellites are working, build a dual-band yagi, make contact with someone via satellite)
  14. digital (data) modes
    1. packet (build our own packet station)
    2. vara HF/vara FM
    3. PSK31
    4. FT8/JS8
  15. time and clocks (how does GPS work, what about atomic clocks, why do we care about accurate time)
  16. amateur radio crossovers with other hobbies (model rocketry, RC aircraft, drones, aviation, etc.)

Again, if there are other topics that interest you, that are not on this list, send them to me and I will add them to the list.  There are so many things we can do with amateur radio... we have only scratched the surface!

Other topics suggested after this list was first posted:

  1. QRP (low power, 5W or less on HF)
  2. Learning Morse Code (I know we're not going to learn the code in a session or two, but we can cover various techniques and tools for learning and maintaining proficiency in code.)

Upcoming Emergency Alert Test on 4 OCT 2023

MASSIVE EMERGENCY ALERT TEST – OCTOBER 4, 2023

*** GENERAL QST MESSAGE ***

 

On Wednesday, October 4 at 14:20 hours ET (12:20 hours Mountain), every TV, radio and cellphone in the United States should receive an electronic warning tone of an emergency alert, accompanied by a notice similar to the following:

“This is a nationwide test of the Emergency Alert System, issued by the Federal Emergency Management Agency, covering the United States from 14:20 to 14:50 hours ET.  This is only a test.  No action is required by the public.”

This test is being run by FEMA to ensure the system is in working order on a national scale.  Local agencies will be participating with FEMA in conducting this test.  This test is being conducted to make sure the national alert system is still an effective means to warn American citizens about emergencies, natural catastrophes, attacks and accidents at the national level.

Salt Lake County ARES will conduct an emergency check-in net immediately following the announcements sent from FEMA.  The check-in net will be conducted on our primary SLCo ARES repeater, 146.700 MHz (100 Hz PL Standard Load ARES1 channel 72).  All stations wishing to participate on this net may do so using normal net-control protocols.  We will also be using our simplex frequency of 147.540 MHz (ARES3 channel 74) to simulate the use-case of the repeater going down during the net.  If you do not hear net control on the repeater this means that we have moved to the simplex frequency.

Any questions about this event, please contact Dan Lundwall via email, n7xdl.dan@gmail.com.
