Locked 1st Annual Minnesota Parks On The Air 6/8/2024 13
You need to mark June 8, 2024 on your calendar because it's the first annual Minnesota Parks On The Air Day! The objective of the day is to activate as many Minnesota Parks On The Air (POTA) entities as possible with a focus on state parks. The second Saturday in June is a free admission day at Minnesota State Parks! I will setup and be operating at Sibley State Park for this event, operating begins at 10am. My hopes are to show up early enough (by 8am) to be able to use the Pavilion, but my backup location will be the parking lot of MT. Tom Everyone is welcome to come out and try their hand at operating HF. Talk in frequency of 146.520mHz simplex and the 444.800- (146.2) repeater.

Locked COMMS trailer work day on 6/1/24 9am 9
On Saturday, June 1st at 9 am to 11:30 am, I'd like to get a few people to help look over the communications trailer. It will be light duty involvement like chasing antenna coax and power supply leads to figure out where they go. There is a couple repairs that need to be made but I'm not sure we'll get to that on this go around. If you feel like lending a hand for a couple hours, it would be greatly appreciated.

Locked The Frugal Ham and solar 5
One of my larger projects has been to convert my QTH ham radio station to run on solar power. My station's layout has the HF is on one end of my house and the VHF/UHF the other. I use two identical 12 volt 4 x 100 Watt solar panel arrays, each having a 100 Amp hour lithium iron phosphate (LiFePO4) storage battery. These type of batteries cost more than lead acid deep cycle, but totally out perform them with usable voltage. Each set up is located near the radio it serves. This minimizes cable loss. You are probably wondering what this cost. Since I built two identical systems, I'll laundry list one. $240 4 - 12v 100W solar panels with weatherproof MC-4 connectors on leads (400W max output). $235 1 - 100 Amp Hour Lithium Iron LiFePO4 storage battery. $60 1 - 12v Solar charge controller with 30A capacity and lithium battery support. $65 1 - 4x6" treated timber and 5 - screw style dog anchors with tie down line and 2 noodles cut to fit panel tops. $100 3 - Wye 2 into 1 MC4 connectors, 10ga x 20' power cable MC4 on one end. Use for solar to controller and controller to battery connections. $40 2 - 4 bolt 5/16" power distribution bars, one red & one black. The radio and accessory power leads connect here, safely and neatly. $20 2 - 10ga - 40A inlineline fuses, 5/16" ring terminals, butt splice, misc shrink tubing. Installation notes. Mounting- The panels are located about 18" away from a south facing wall with their bottoms set in the grooved landscape timber. The timber is anchor nailed to earth. Split swim noodles are used to protect the siding from the solar panel tops. Slit length way and paint with latex to protect from sun damage. The panels have a pair of mounting holes on each side. Two lines are threaded across the top and bottom holes then tied to the anchors on each side. Four panels requires 5 anchors to securely tie them down. Electrical- There are 3 pairs of 2 into 1 weatherproof wye MC-4 connectors allowing the panels be connected in parallel. 10 gauge cable connects the 4 panels to the battery charge controller located indoors near the storage battery. There are many solar chargers to choose from. I use the one in the picture with very good results. It also has stout wire terminals compared to others. The charge controller's output connects via 10 ga cables and a 30A in line fuse in the positive lead to the battery terminals. The battery is also connected to the 12 volt distribution bars with the positive lead fused at 30A. I recommend buying a good crimping tool. A tight, gas free crimped connection seldom gives any trouble. Poor connections will get hot and waste Watts. American made connectors tend to be stouter in my experience.

Locked VARA-FM and Digirig hint - receive audio level won't settle
Something else I have experience happened when I moved the Digirig to another USB port on my laptop computer running Win 11. When I restarted VARA FM the VU meter audio level appeared to be connecting then disconnecting. Right click the Windows icon then select System> Sound> You may notice the Windows Digirig ID has a number behind it indicating a 2nd installation. Scroll down to mic audio. Select OFF under the normal audio enhancements button. This turns OFF the auto gain for the mic input. That is what caused the problem.

Locked Fun and useful stuff to do with Winlink
Ben W0AYE was showing me some interesting information gathering you can do with Winlink's catalog request feature. When you click on the icon below my arrow Winlink opens up it's catalog. Here's what the Winlink Query Catalog looks like. Scroll through the categories to find items of interest. Clicking on the category fills the center window with it's contents. Double clicking on a selection will put it in the selections window as in the example below. It is a small satellite picture of the current view in the description. After you put together the selections you are interested in getting (remember 100k download limit), click on Post Request button. Now there is a out going request email in your outbox. The next time you connect to the gateway (W0AYE-10) it will get sent. Wait a few minutes and connect again to check your email. The requested files will be downloaded to your station. 73 Mike N0QBH

Locked Meshtastic overview 5 #projects
Introduction Meshtastic? is a project that enables you to use inexpensive LoRa radios as a long range off-grid communication platform in areas without existing or reliable communications infrastructure. This project is 100% community driven and open source! Features? Long range (254km record by kboxlabs) No phone required for mesh communication Decentralized communication - no dedicated router required Encrypted communication Excellent battery life Send and receive text messages between members of the mesh Optional GPS based location features And more! How it works? Meshtastic utilizes LoRa, a long-range radio protocol, which is widely accessible in most regions without the need for additional licenses or certifications, unlike HAM radio operations. These radios are designed to rebroadcast messages they receive, forming a mesh network. This setup ensures that every group member, including those at the furthest distance, can receive messages. Depending on the settings employed, the Meshtastic mesh network can support up to 100 devices concurrently. Additionally, Meshtastic radios can be paired with a single phone, allowing friends and family to send messages directly to your specific radio. It's important to note that each device is capable of supporting a connection from only one user at a time." ? When you send a message on your Meshtastic companion app, it is relayed to the radio using Bluetooth, Wi-Fi/Ethernet or serial connection. That message is then broadcasted by the radio. If it hasn't received a confirmation from any other device after a certain timeout, it will retransmit the message up to three times. When a receiving radio captures a packet, it checks to see if it has heard that message before. If it has it ignores the message. If it hasn't heard the message, it will rebroadcast it. For each message a radio rebroadcasts, it marks the "hop limit" down by one. When a radio receives a packet with a hop limit of zero, it will not rebroadcast the message. The radio will store a small amount of packets (around 30) in its memory for when it's not connected to a client app. If it's full, it will replace the oldest packets with newly incoming text messages only. Getting Started Identify Hardware? NOTE This guide assumes that you have already purchased the devices you will be using with Meshtastic. If you haven't, you can check out our list of supported hardware to see your options. Before you begin, it's important to determine which kind of hardware you're using. Meshtastic works with devices that have these types of Micro-Controller Units (MCU): ESP32? The ESP32 chip is older and consumes more power than the nRF52 chip, but is equipped with both WiFi and Bluetooth. Supported ESP32 devices include: LILYGO? TTGO T-Beam (>V1.1 recommended) LILYGO? TTGO Lora (>V2.1 recommended) Nano G1 Station G1 Heltec V3 and Wireless Stick Lite V3 RAK11200 Core module for RAK WisBlock modular boards nRF52? The nRF52 chip is much more power efficient than the ESP32 chip and easier to update, but is only equipped with Bluetooth. Supported nRF52 devices include: RAK4631 Core module for RAK WisBlock modular boards LILYGO? TTGO T-Echo RP2040? The RP2040 is a dual-core ARM chip developed by Raspberry Pi. Supported RP2040 devices include: Raspberry Pi Pico + Waveshare LoRa Module (Note: Bluetooth on the Pico W is not yet supported by Meshtastic) RAK11310 Core module for RAK WisBlock modular boards INFO If your device is not listed above, please review our supported devices to determine which MCU your device has or contact us in Discord with any questions. STOP! PUT THE POWER CABLE DOWN! Never power on the radio without attaching an antenna! It could damage the radio chip. Prior to connecting your Meshtastic device to the computer, you should perform the following basic checks. Verify Data Cable? Some cables only provide charging, verify that your cable is also capable of transferring data before proceeding. To check if your cable can also transfer data, try connecting it to another device (like a phone) and see if you can copy a file to or fr

Locked Home Brew Co linear antenna design for VHF/UHF
When I was in radio school we cut a removed from service co linear antenna in half. I was surprised when I seen how simple the innards were. These type of antennae are usually vertical polarized and depending on the number of sections, can really squeeze the pattern flat to the horizon with resulting gain. This PDF has a simple design using sections of coax soldered together in an alternating fashion. 73 Mike N0QBH

Locked The Frugal Ham 2
Most Hams I've met like a good deal. In fact, it's probably one of the few things non Hams can understand about us. To that end, I decided to try different ways of constructing a quality Winlink station for not a lot of money. One of the requirements is a newer Windows computer. Win 10 versions older than Mar 2018 will not work. Previously I described using new low end laptop notebooks by turning off the Windows 11 "S" feature, allowing programs to be installed. In this blog I'll describe using a new BMAX $100 mini Windows 11 PC, along with a $50 Digirig, $30 in cables and your radio. The Digirig has been discussed before, but to summarize, it acts as a USB audio interface with radio PTT and CAT control. We'll assume you have a HDMI or VGA computer monitor, USB keyboard and mouse already. The BMAX comes with a 12v DC power supply (it could be off grid friendly) and a HDMI cable. It has plenty of I/O with 4 USB connections, VGA and HDMI video outputs. After following the initial setup instructions giving the mini PC a name and password as well as where in the world it lives, I did a power down restart. Then I copied the necessary Winlink zipped files to the mini PC downloads directory from a thumb drive and extracted all there. They included Winlink Express, VARA FM, VARA HF (optional), VARA CHAT (optional) and always, the Silicon Labs universal driver for Digirig's UART. Winlink and VARA installation was trouble free. Since I am a Winlink user, I just copied my Winlink password and personal info to the new install. I'm presently using it as my Winlink HF station computer where it is coupled with a Yaesu FTdx-1200 transceiver. The CAT control is convenient and works smoothly. Sweet! I've never had CAT before, I'm spoiled. It replaced a desktop PC and I cannot tell any performance difference, just a lot more room on my desk. I'll give it a thumbs up. Oh, I almost forgot - there's no bloatware on this computer! 73's Mike N0QBH

Locked The Case for Winlink locally 2
In an earlier mini essay, I made the proposal to convert the WILMAR 400' packet radio station to an APRS digipeater on 144.390 MHz. In this one, I'll discuss the reasons why we might consider keeping it on 145.670 MHz and changing it to a Winlink Gateway. The first point needs to be emphasized - how under utilized this asset is as a packet radio node. It's height and quality installation give it coverage over a wide area surrounding Willmar, yet it has no users. This day in age, packet radio is simply too primitive and too slow to attract new users or to be useful in emergency communications. Since the money spent for the packet station came out of 9/11 Homeland Security funding, it would seem logical they intend this to serve in emergencies. In 2004, packet radio was the logical choice. In the twenty years since, software has evolved, giving us several better options to move information via radio. Winlink has become a popular choice because it has a simple and versatile format, email. As one of the better thought out solutions, in my opinion, Winlink offers each user a number of methods to send and receive their email, depending on what's available. The built in options range from Telenet (Internet), Packet, Pactor, Ardop, VARA (voice radios) and Iridium (satellite). Because the Winlink emails are the same format, they can move through any of these modes on their way to the destination. Flexibility is key and Winlink has it in spades. It's also free to use as is the VARA modem software. What it needs in this area are experienced operators. We gain this experience by doing (operating). In the case of Winlink, an easy way to fulfill your training is to use it for your Ham radio related emails. Normally, the local Winlink gateway is connected to the Internet. The emails you send and receive thru it via radio will use the Internet from there on. You are allowed attachments up to 120 kbytes total message size. However, only VARA FM will transfer data fast enough to do this with your 2m transceiver. Presently, we have a Winlink VARA FM gateway station located in Willmar on a 60' tower. It's accessible to Hams with a line of sight path and an outdoor antenna, mostly within a 15 mile radius. Having a gateway on the 400' tower would at least double the radius, making access reliable for a much larger area. Along with a much larger coverage hopefully comes more users. If it becomes too busy, we can expand another gateway on another frequency and or location. Usually, a FM gateway will respond to either VARA FM or Winlink packet connections on it's frequency. Once the connection is made the process is automatic. The user can abort the connection if something goes wrong or hangs up. When the message transaction(s) are done, Winlink disconnects, making way for the next user. To summerize, we have an outstanding resource in the WILMAR station that is underused. I am presenting options to change that and still remain true to it's purpose. 73 Mike N0QBH

Locked Happenings Dakota Division 每 March 18 - 25
With spring arriving our winter temperatures return. Perfect time to start thinking about Field Day. There are no major changes this year. Reminder the GOTA station now isn*t limit on the amount of QSO*s they can make. In the past sites would hit the maximum limit and shut down the station, reducing the opportunity to expose visitors and beginners to operating a ham radio. Now you can keep the GOTA station on the air and active all weekend earning you points for every contact they make. There is a new bonus this year, 50 points for a Site Responsibilities person. I looked at the check list, and it still needs some work. The intent is to have a person responsible for making sure the site is welcoming to visitors and guests, information about amateur radio and your club is available, you have a way for people to get directions such as a talk-in frequency that is monitored, etc. So, watch for changes to this check list in the weeks to come. While you are at it make sure you get the appropriate local officials invited to visit and have someone ready to give them a tour around the site explaining what is going on. The last key thing is to make sure you get your Field Day operation on the ARRL Field Day Site Locator. This is helpful for people traveling to an area to find a site as well as myself and your section managers to find your site. I suggest getting information listed as soon as you know your group will be doing it.

Locked Digirig cable builders - Beware cheap TRRS 3.5mm plugs at Jungle Store
I recently purchased a 4 pack of Fancasee 3.5mm TRRS solder on plugs from Amazon to convert a couple of cables for use with the Digirig USB soundcard radio interface. After I soldered up the cable to the connector and tried it out, I noticed transmit audio was coming thru the radio's speaker. Switched back to the Digirig factory cable and it went away??? The micrometer and a visit to Digikey to get the specs on a known good part showed a .050" difference in overall length - the cheap plug was too long allowing the TIP to touch R1 inside the jack. This, in turn shorts transmit and receive audio together. Hope this helps someone else. A $4 quality part beats a $2 cheapie most days... 73 Mike N0QBH

Locked A Short Note on VARA and Winlink :)
The local Winlink gateway has been on line for several days as I type this and it has been working well. I have been sending and receiving my Ham radio related emails in this manner and in the process, learning the ropes of operation. Presently, the only connections are VARA FM mode on 145.070 MHz. Ben tells me 1200 baud packet access will be added on the same frequency. Winlink packet is not quite the same as regular packet, but it uses the same hardware and can digipeat thru packet nodes to another Winlink station. Which brings us to "How do I do get and use Winlink?" You need a Windows 10 or newer computer to use Winlink and VARA. https://downloads.winlink.org/ The two programs are Winlink Express set up in the user programs area and you want VARA FM set up in the VARA products subdirectory. Both programs download as zip files. I recommend extracting while still in the downloads directory. The unpacked result is a installer program . The Winlink program will want to install in the root directory. Use it's recommendation. I learned the hard way that programs I installed in the program files directories are in protected memory. Windows won't let anything write in there, meaning saving configs that normally live with the program don't happen. To use Winlink you have to be registered (free). You register from within the Winlink Express program. It involves giving your valid callsign as your user name and you chose a recovery password. Then, assuming you have Internet, it will Telnet your application into headquarters and you are set. You will need a software modem to let Winlink communicate via radio. Around here VARA FM is the best method. VARA FM is downloaded and treated the same as Winlink - unzip and install it where it wants to go. You will need to run the installer as administrator (right click mouse) and select that option. Next, is determining how to connect the radio to the computer. There are several ways, I've tried many of them. Digirig is far in a way my favorite. Small, inexpensive ($50) and a great selection of cables for oodles of different radios, all under $30 ea. https://digirig.net/store/ USB soundcards can be intimidating to set up. Digirig's audio is "plug n play" - no drivers. The serial side is apt to need a driver download. Silicone Labs CP210x Universal Windows driver is what you will need. The install page on the Digirig web site shows how to install the new driver, if needed. It's important as it controls the PTT of the radio. It's a good resource and I recommend reading it first. https://digirig.net/getting-started-with-digirig-mobile/ Once you have your Winlink VARA FM station all talking to and hearing the radio, you will need to make a note of what USB port on the computer you are using. To keep life simple, always use that same port. If it isn't possible, you may need to reload the USB driver to the new port in order for the serial PTT to function. Another thing I've noticed with Windows and USB just seems to take time, sometimes :) Step away and have a cup of coffee and sometimes you'll return to working drivers. The last two steps before attempting a Winlink connection is to calibrate the audio levels in and out of the radio. Pretty easy usually. With the VARA FM program itself running, insure the squelch is open if you don't see any movement of the VU meter on the dashboard display. If your radio uses a RX data connection in the back, you only need to adjust the USB Soundcard mic in levels to get the VARA VU meter needle to the 2 O'clock position. If you had to open the squelch, you will also need to adjust the volume and USB Soundcard mic in to get the VU to the 2 O'clock level. This is because that audio is coming from the speaker. Setting the transmit audio level is done with another VARA FM station using the Auto tune function found in the VARA FM program soundcard button. Your frequency must be the same as the other station, around here we are using 145.07 MHz for VARA FM. When you start auto tune, your station will send a series of 10 tones at gradually louder levels. If the other station hears you, it answers back with a pass or fail and tells you what to adjust. It also sets the slider level in the auto tune display. Note, this adjustment is in series with the USB Soundcard Speakers (Digirig out to the mic) Windows slider. We normally use W0AYE-10 as the other station since it's who we'll usually be connecting to and it's a known good signal. That's all for this segment, next one will focus on operation. One of the best places for Winlink info is it's HELP menu. I will try to be available to talk someone thru installation and am usually listening on the 444.8 machine. Else try n0qbh@... 73 Mike N0QBH

Locked VaraFM Gateway News 7
For those interested, the W0AYE-10 VaraFM gateway is now installed in the amateur radio room at the Kandiyohi County EOC located in Willmar. The gateways' antenna is an omni directional vertical on top of the EOC's 60' tower. The gateway radio is a Yaesu FTM-6000 using a Digirig soundcard running 25w. I have changed the gateway frequency to 145.070 MHz to stay inline with other emcomm Winlink frequencies in Minnesota.
