Tech Night – The NanoVNA

Presentation: The NanoVNA – more than just an SWR meter

Scheduled Date / Time: Wednesday June 26th 07:00 PM 

Location: BARC Clubhouse

Presenter: Mike Suhar, W8RKO

Presentation Topics to discuss include:

   1.  Software that works with the NanoVNA

   2.  How improper calibration and device-under-test (DUT) hookup can lead you astray

   3.  Using the NanoVNA for measurements other than antenna SWR

   4.  Device protection

   5.  Example of designing a short antenna for 40-meters and the matching network.

This should be an excellent presentation; highly recommend you attend …. Bob AC8ZU

Future Tech Nights:

  • July 31, 2024 – Build Budget Code Practice Oscillator) – Tim Procuniar, N8NQH and Jim Gifford
  • August 21st and 28th – Build-A-Hotspot – Ray Hitt N8VMX
  • September 25th – TBD
  • October 30th – TBD

I hope to keep us planned for at least 2 meetings ahead, so people have enough time to purchase components if needed.

Current Presentation Backlog and growing. It would great if you can present or assist others.

  • “Duplexers and Tuning” – Tim
    • Why duplexers are needed for repeaters, and actual tuning demonstration. Around 60 minutes.
  • “APRS-GPS” – Tim
    • A 101 type presentation on the basics of APRS and sending your GPS coordinates over ham radio.  40 minutes.
  • “Wide-Narrow Band” – Tim
    • Takes the confusion out of the use of “Narrow” and ‘Wide” in this 21st century.  Short, 10 minutes; most of the time this is included with one of the other presentations.
  • “Usage of microcontrollers in Ham projects” Part 1 – Bob
    • Demonstration of Arduino IDE, MicroPython and Microcontroller simulation software. Discussion of practical application of the technology for Ham Radio.
  • Setting up and using a Raspberry Pi 4 or 5 either as a ham shack digital mode computer or for FT-8 on POTA. – Ray
  • KiwiSDR presentation: The presentation will be mostly on the worldwide network the receivers are connected to.  How you can use the network of receivers for ham radio and other interests. Mike Suhar  W8RKO
  • Solar / Battery Powered micro radio builds
  • Raspberry PI for POTA (Technight and POTA related)
