Only a few more days! DMR Hotspot Workshop Sunday March 19th 2017 2pm

It’s coming this weekend, the MinnesotaDMR HotSpot Workshop at the Maplewood public library is just days away. Note the change in time. We are now able to get in early for setup so we will begin sharply at 2pm. Please arrive by 1:45 to get comfortable or 1:30 if you would like to help setup.

Please visit this survey to let me know if you are interested in attending. I need a good head count so I can prepare handouts for you. https://www.surveymonkey.com/r/YV776ZG

Location: Ramsey County Library – Maplewood – 3025 Southlawn Dr, Maplewood, MN 55109

The Presentation is available at: https://docs.google.com/presentation/d/1b9JXCMXYOVGXSE0_xZ7jYVDZOTpaNgmxYIRJ29m8CxA/edit?usp=sharing

Here’s a list of things you should be prepared to bring with you.

  1. Pen and notepaper if you wish to take notes…
  2. Raspberry Pi 3 or 2.
  3. SD flash card for your raspberry pi computer. You might want to bring a spare, just in case. 16Gb or larger recommended. 8Gb minimum size. You may also need an adapter to connect the SD card to your laptop to copy software for the first time.
  4. Power supply for your raspberry pi computer.
  5. DVMega radio board. (Note that I have them available for $105, but the library prohibits sales in their meeting spaces so we need to meet before hand.)
  6. You may wish to bring a case with a hole already in place for your antenna or I can sell you a case in advance (no sales allowed at library) for your Pi and the DVMega radio board. A case is optional if you are careful handling your Pi computer. I have them for 10 bucks.
  7. An antenna with an SMA Male connector for the DVMega radio board. I have antennas available too. Shorter ones for $7 and longer for $10. Most MD-380 and MD-390 radios were shipped with two antennas which are compatible. The two antennas I stock are identical to the stock TYT/Tytera UHF radio antennas.
  8. Extension cord 7 to 15 feet in length, preferably with an outlet bar so you can power your neighbors extension cord, a monitor, a laptop, your pi computer and maybe the same for the person next to you who didn’t bring one. The meeting space has very few outlets around the outside of the room. We need you to bring plenty of cords so everyone can power up. Please label your cords if you want them back.
  9. Keyboard if you have one you can bring. I may have a couple to loan, however you might want to use one without waiting.
  10. Laptop computer to connect with your pi for setup, to flash the SD card and to reprogram your DMR radio. If you do not have one, it’s OK, it is not absolutely necessary, but will delay things for everyone else.
  11. Your DMR handheld radio. Please bring a radio so you can test things out.
  12. Your programming cable for your DMR radio (If you don’t have a cable, I’m sure someone in attendance may be able to assist.
  13. Video cable? I will be bringing a dozen computer monitors which have a DVI video input. The Raspberry Pi computer has an HDMI output. I have 5 cables to connect the 12 monitors. We should only need a monitor and keyboard briefly to setup our network and WiFi settings… After these are known/configured, you will use a laptop if you have one for the rest of the configuration.

What you should preferably know and bring with you before you attend:

  1. Your DMR radio ID, they are 7 digits long and in Minnesota start with 3127???
  2. Your WiFi SSID Name (It is case sensitive and you should double check)
  3. Your WiFi Network Password
  4. If possible, find out if or what type of authentication/encryption your WiFi uses: WPA2, WPA or WEP.  Next find if you have AES or TKIP… This information may be needed if you want to preconfigure your hotspot to connect with your wireless network at home, work, school, car, where ever.

Minnetonka back online

Today my repeater located in Minnetonka at Don Rice’s house was replaced with a Motorola XPR8400. Don wasn’t satisfied with the selectivity or purity of the Yeasu Fusion DR-1X repeater I modified for DMR use and he switched it off a couple weeks ago. That changed today as it’s now a Motorola rig and appears to be performing very well. The Fusion systems just are not as good in locations with multiple radios or high levels of RF present. Thank you again to NØBVE for hosting both the Chaska and Minnetonka systems. Of course Don also provides his own DMR equipment at his sites at RiverView (Some refer to this as MSP) and his other system at the MSP airport. Someone buy him lunch as without his support we would be short 4 of the best performing locations in town. Thank you Don!

PS: Thank you to “Scanner” again as well for checking up on the new duplexers I’ve added to my collection of equipment. What you are looking at here is a couple paychecks. 3 quality duplexers and the new repeater.

What’s a CodePlug? Where’s that name come from?

Back in the good old days, radios used crystals to control the frequencies, and sometimes had internal jumpers that were set for the various options. Some time later on, they moved the internal jumpers to a jack on the back of the radio. They configured plugs with wire jumpers in them that plugged into the jack to enable certain options. These became the original code plugs. Later on, more things were controlled by these code plugs, such as tone encode/decode selection.

As radios became microprocessor controlled, the external code plugs moved inside the radio as programming information. The term has, unfortunately, remained with us, although there’s not much that still plugs in. The code plug contains the operating frequencies, tone selections, timeout values, system IDs, etc. In some instances, there’s even some parts of the program itself in the code plug which defines a radio’s personality. These days, the code plug is just a relatively small binary file that’s managed by software a program and transferred to or from the radio via several proprietary means.

Top 50 DMR Radio ID’s in the last 50 days

Anyone ever wonder who’s doing all the yacking on Minnesota Statewide. Brandmeister can provide some beautiful statistics and I thought I’d share the top50 ID’s from the past 2 months. I see all 3 of my radio ID’s made it into the top 20. Yikes.

Updated a few radios tonight

If you are interested in the Travis GoodSpeed “Hacked” or Patched firmware for your TYT or Tytera MD-380 or MD-390 radio, Let me know on the MinnesotaDMR mailing list. This evening at the Bloomington Communications Group monthly meeting, I had the opportunity to update a couple radios and I would be happy to lend a hand updating yours.
