A couple of useful applications for your Meshtastic network 3 #Meshtastic #projects
Besides texting there are a number of other things you can do with those little Meshtastic devices. There are two named modules (think configuration) that can come in quite handy. The first is the Detection Module. It has a small menu that lets you pick a unused I/O pin on the mesh radio to monitor. It also has weak pull up available to make a 1 wire to ground circuit. This can be sensed as open or closed with a series switch. In my application I have a magnetic reed switch door sensor in series that will trigger an alert text that will be sent over the network all or to a specific radio. https://meshtastic.org/docs/configuration/module/detection-sensor/ The second application came from some scrounging in my junk drawer. I had some unused 3.3 volt Bosch BME280 temperature/barometer/humidity sensors from a weather station project. They are very popular and available for under $5. Four wires including power/ground connected to the user pins on the radio is the hardware. Enabling it in the Telemetry Config menu turns it on. Now you or anyone in your network can view the current conditions at the radio's location. https://meshtastic.org/docs/configuration/module/telemetry/ In previous postings I've shown how you can run these Meshtastic radios remotely using solar power year around. Put this all together and you can have a remote, self powered node that can observe it's environment. 73 Mike N0QBH

A tale of two Baofeng UV5R radios 3 #radios #VaraFM
Awhile ago I ordered a cable assembly from Digirig for the Baofeng UV5R model handheld radios. The cable is prewired for the Digirig and comes with a second programming cable that uses the Digirig's serial capabilities allowing a program like Chirp to read and write the radio's program memory. My reason was to see if the inexpensive $35 Baofeng radio will work with VARA FM and Winlink for nearby stations accessing the W0AYE-10 gateway. The results? Yes and no. I have two of these radios, one a few years old and the other purchased in the past year. Both UV5R model. The old one works VARA FM like a dream and seems to be a rival to the Yaesu FT-60 I've been using. The new UV5R with identical settings, on the other hand, is unable to complete a connection with the gateway. It's transmit to receive turnaround time is way too slow for VARA causing the incoming data to be missed. Searching the Internet showed this to be a very common issue with the Baofengs and VARA FM. What remains unclear is if the problem is model change related or variations within same models. If you have one and want to find out, I can probably test it before you spend $35 on a cable set. For folks planning to use handheld radios, invest in a gain antenna around 2' long. Night and day difference in signals. 73 Mike N0QBH

Sunday Night Net while Tony's away #netcontrol #repeater
Tony WD0HXV is heading to 7 land to hang out with his dad W0BAM for the month of February, so myself and others will be trying to fill in as Net Control. One of the things we want to try is a before the net rag chew on 146.91 starting around 15 minutes before the net at 6:45. That way Hams who want to chat with other members are likely to run into them on the air. The test net itself will remain the same at 7:00 pm, going through all three machines starting with the 146.910 then 147.03 and 444.800 last. This way we are done in plenty time for those who participate in the Litchfield net @ 7:30. Hope to hear everyone Sunday eve. 73 Mike N0QBH

APRS using HF VARA 5 #APRS #HF #VARA
Here's a new rabbit hole to go down that could be rather interesting. I used to do HF APRS with a MFSK16 tracker I designed and built. It worked surprisingly well, but HF mobile operators are scarce. Fast forward 15 years and they are doing it much better with VARA. Stephan Smith WA8LMF is the stateside "guru" tho I will warn you, he's abrasive and doesn't suffer fools. He's an engineer in the mold of Sheldon at times. http://wa8lmf.net/VARA/APRSoverVARA/ I'm think about trying the Pinpoint version with my VARA HF station. 73 Mike N0QBH

How I improved my VARA FM speed 3x 4 #VaraFM
Awhile back I exchanged computers in my VHF VARA FM shack from a laptop to a solar powered Bmax B4 mini PC. Right away I noticed the 4 signal "dots" in the diagram display went from being tight centered dots to somewhat splattered "dots" when I was connecting to the gateway. I wasn't able to adjust it out and just assumed it was the new normal for this PC. Also, it didn't seem to affect performance as it was before the Willmar gateway was connected to the Internet. After we got on line and it was easy to order up large attachments to download from the catalog, I noticed the throughput from the gateway to my station wasn't as fast as I remembered it. Since around 40k/minute is pretty fast anyway, I didn't worry about it. Fast forward to this past week. As a solar operator I call it "h_ll week" because the days are the shortest and it's often cloudy. This tests the system and I found 3 days was where I ran outta gas if the station(s) were operating 24/7. Good to know. Today being the 4th day had me switching my hardware over to the grid so I could continue to operate... Ok, play. :) The first thing I noticed when I useded the mini PC on a wall wart was the dot's in the signal diagram were round and very tightly grouped again when connecting with VARA FM. Hmmm. I ordered up a 50k weather file and was blown away at how fast it downloaded from the gateway - 120k/min!! I did a few more to prove it wasn't a fluke. Nope, no fluke. The other thing I noticed was how the diagram had 32 squares instead of 16. VARA figured out my system had better hearing and used it. I swapped power sources back and forth til I narrowed it down to a undersized, unshielded, too long cable powering the mini PC. Moral of my story - learn to trust your visual indicators. In this case power supply noise was going out the mini PC USB to the Digirig, raising it's noise floor dramatically. This was like tatters in it's ears. 73 Mike N0QBH

Solar Mesh node power experiment 9 #Meshtastic
One of the issues operators have with remote solar powered anything and lithium batteries is cold weather. They don't like to be charged at below freezing temperatures. Thanks to another user I discovered a possible method of preventing battery damage using a Thermal reed switch. It appears to be a normal magnetic operated reed switch with a substance called Thermorite orientated as a magnet. According to the spec sheet, Thermorite is a ferromagnetic substance who's magnetism decreases with rising temperature. Depending on the recipe, it can be made to operate at specified temperatures. I've ordered one to switch open at freezing (0C). It will be in contact with the lithium battery and the switch in series with the 5W solar panel. Specs say it can handle 10W. Anytime the battery is too cold, no charging will occur. If it works out, the next thing will be to see how much storage I need to get thru the sunless days. Here's a link to the data sheet. Digikey carries them. Not cheap at $30 ea. https://search.kemet.com/download/datasheet/TRS1-0MSR01EV 73 Mike N0QBH

SSTV local net 5 #repeater #SSTV
I'm gauging interest in having an impromptu SSTV net after the W0SW net on Sunday evening to exchange a few pictures. I'd like to host the net on the 147.03 repeater to let more folks tune in and copy the signals S-9. We used to do it 30 years ago without issue. Slow scan FM is no different than voice communications from the repeater's standpoint. However, I thought it would be a good idea to get some club member input first. Leon KF0OUA and myself have done some SSTV simplex on 146.550 and it works well between us because we have fairly tall antennae. Doing over the repeater just lets more folks get good copy. Opinions? Questions? Answers? :) 73 Mike N0QBH

Winlink county specific weather report 6
I copy and pasted this info from the EAST-COAST Winlink net but I thought this is too good to not pass along. This week, we are going to help you get a weather report that is only for your specific County or Weather zone. We are also going to help you create a Template in Winlink, so in the future, the weather report for your specific county or area will only be a few mouse clicks away. Don't worry, it is not a complicated project! I am going to talk you through it, step-by-step in this message. The first thing you will need to do is visit this website: https://www.weather.gov/pimar/pubzone Once you are on this website, find your State or area in the list, and click on either the PDF or JPG highlighted link. (My preference is for a PDF file). Once you click on that file, a map of your state or area will show up. Each County or area will have a 3-digit number. Either print out the map, or write down the 3-digit number for your County or area. Now you want to go back to your Winlink program and click on MESSAGE to expand the list, and scroll down and select TEMPLATE MANAGER. For most of us, 3 choices will appear, which are Standard Templates, Global Templates and a choice with your Call Sign Templates. You want to click one time on your call sign templates so that it is highlighted. After your Call sign Templates is highlighted, go to the top of that window and click the word ADD. A new window opens, and you are asked to Name your template. I suggest that you name it with the name of your County and state and the words Weather Report behind it. (Example: Renville County MN Weather Report) You should leave the little radio button for Call Sign Specific highlighted and click the CREATE button. A new window will open, and you will need to enter the information below in that window: (The information below creates a Renville County MN Template. For your personal template for your County or area, you will change the Subject name, the cd state abbreviation, and where it says get mnz065.txt, you would enter your 2-letter state with the letter z followed by the 3-digit code followed by .txt ) Type: Winlink To: nws.ftpmail.ops@... Subject: Renville County MN Weather Report msg. open cd data cd forecasts cd zone cd mn get mnz065.txt quit After you have entered the above information (edited for your County or area) you want to click SAVE and close out the window. To use your new Weather Template, Click MESSAGE like you were starting a new message, then click SELECT TEMPLATE, then click the + sign next to your call sign and look for your County Weather report that you have created. Double click on it so that it opens. When your message template opens, just click POST MESSAGE, and then open or run a Winlink session to exchange your message. Wait a few minutes and open another Winlink session to check for mail, and your new Weather Report message should be there.
