Winlink exercises

Bill McFarland - N0AXZ
 

Group,
There were a good number of us using Winlink for the SET, but things keep changing and we need to practice to keep our radios doing the right thing as we can forget over time of non-use.

So I am asking for those who would like to do a Winlink exercise once a week to respond to this email. I will take a week to collect your red hot responses and then make a group of Winlink practitioners to which all subsequent emails will be sent. 

What would you be getting into?

Each week I will send you some instructions via your regular internet email describing what you should try in a Winlink session. You will have a few days to do the homework and send your Winlink message. You can use any mode and any RMS node in general with some exceptions. We will experiment with forms, and pictures and some Peer-to-Peer opportunities, and some Tactical call signs with all that. We will specify some non-local RMS nodes to see how well we can get out of the county (HF) should we need that in some emergency response. (but we don't want to swamp any node with all our messages :)

So I would send out a play on Sunday night and you would have until Thursday 11:59 PM to send your Winlink message to me. That will give me Friday and Saturday to see how we are doing and what comes next (or REPEAT).

The developers of Winlink are continually improving the system so we need to open Winlink Express and take the updates that pop up regularly. For instance the Check--in form has just gotten a significant change. You will need to know your GPS coordinates and now they have added What 3 Words (W3W). If you don't know what that is, your first assignment is to find out what your W3W are.

It will be fun and educational all at once. If you have never used Winlink before but are willing to try sending email by radio, join us and ask questions and get help setting things up. At the beginning if you don't have a radio connected to your computer, you can use the Telnet session which only requires you to have internet to play. 

Please send your requests to join, or questions before you commit to me off-list (billmcfarland10@...).

Happy Holiday,

Re: December CMRA Meeting In Person

Jon Cole
 

Hello all,

I recently became aware that the Boone County building has their rooms available for groups again, so I decided to try there, and the schedule worked.  We can hold our CMRA meetings there in person now and I have the room booked for the next six months.  I plan on being there in person and invite others to join me as well, COVID permitting.  If COVID becomes an issue again, we can revisit the issue and return to Zoom.  Hopefully someone will be able to make some technology work and turn this into a hybrid in-person/Zoom meeting.  Any volunteers?


Boone County Government Center
County Commissioners Chamber
801 E. Walnut
Columbia, MO 65201

The after-hours access is via the west door that opens onto the plaza between the County building and the courthouse, south of the intersection of Ash Street and 8th Street.  There is on-street paid parking (paid until 7 PM) on the north side of the building.  North of the building and across Ash Street are two parking lots for county employees that are open to the public after 5 PM.  It is in the round part of the building.

Also, our December VE testing session will be held at the same place at 6:30 PM on Tuesday, December 21, 2021.  The January, February and March testing sessions will need to be held on the third WEDNESDAYs due to a scheduling conflict for the room.  Hopefully there will be enough VEs available for the Wednesday sessions.

If you have any questions, feel free to ask.  :-)

Hi

I am posting this because proposed new standards use spectrum under 1 GHz. Another new WiFi service extends range to one mile (line of sight).

This series is chocked full of interesting trivia about the RTL-SDR type dongles and some setp up models. It includes comparison of representative units but I found the more interesting information talks about software. There are a bunch of freeware software apps which allow you to control your SDR. You can even decode trunking DMR. And there are a bunch of internet connected DMR radios in many countries.

Awesome video, thanks Fred!  This video spurred an interesting conversation with my step dad who is a retired electrical engineer and a former navy submariner aboard the USS Grouper in the late 50s and early 60s.  https://en.m.wikipedia.org/wiki/USS_Grouper
For comms in his day they would come up to snorkel depth, 56'  and float an antenna  bouy.
