Parks on the Air – Presentation

Here is a chance to learn to have some fun outside while operating your ham radio. While also letting your fellow ham operators chase you as you explore our natural resources of our park system.  Curtis Turner, KB3CMT gave this great presentation during our Wednesday night social meeting.

And stay tune for this summer road trip when the Steel City club takes to the Parks operating “Parks on the Air”

Hamcation Webinar Video’s

Hamcation videos have been posted to YouTube now. The only good thing that has come out this COVID people can’t travel so the fine folks down in florida have put their excellent presentations on the Internet so everyone can learn from them.  Included those of us that just can’t get away this time of year now have a chance to see them. Here are just some of the video you will find on there site.

  • SDR ~ Software Defined Radio
  • Build a Mesh Mobile Tower Fleet
  • YOTA 2021 ~ Youth-On-The-Air
  • The World Famous K3LR Station and Antenna Farm
  • Kit Building Techniques For Success
  • ARRL – ARES…a team moving forward!
  • AMSAT CubeSat Simulator
  • West Mountain Radio – DC Power technologies, Batteries and Solar

HamCation – QSO Party & Webinars

The Orlando HamCation Special Edition online event and QSO Party will take place this weekend, February 13 – 14. The online event will include youth, technology, contesting, and vendor webinar tracks via Zoom.

ARRL will also present two webinars on Saturday, February 13. The ARRL Member Forum at 1 PM EST, will be moderated by ARRL Southeastern Division Director Mickey Baker, N4MB. Presenters include ARRL CEO David Minster, NA2AA, and ARRL Director of Emergency Management Paul Gilbert, KE5ZW. Gilbert will also moderate an Amateur Radio Emergency Service (ARES®) presentation at 3 PM EST. The ARES presentation will include ARRL Northern Florida Section Emergency Coordinator Karl Martin, K4HBN, and Southern Florida SEC John Wells, W4CMH.

The HamCation QSO Party — a 12-hour on-air event, will also take place this weekend. Nine HamCation special event stations with 1 × 1 call signs will be on the air with combined suffixes spelling out HamCation (e.g., K4H, W4A, K4M, etc). Each contact will count as one point, and stations may be worked once on each band and mode. Scores will be posted on www.3830Scores.com — no logs are required. Plaques and certificates will be awarded.

WSJT “FT-8” New Release

The WSJT Development Group has announced the general availability release of WSJT-X Version 2.3.0. A summary of new features can be found in the WSJT-X 2.3 User Guide. The Release Notes offer additional information, including a list of important program changes since the WSJT-X 2.2. Upgrading from earlier versions of WSJT-X should be seamless, and it’s not necessary to uninstall a previous version or move any files. Installation packages for Windows, Linux, and Macintosh are available. A release candidate (i.e., beta version) WSJT-X version 2.4.0-rc will be available soon. Its main new feature is a mode called Q65, with unique capabilities for EME and scatter propagation modes.

Raspberry Pi Pico

The rise of the micro controller has one new board out today. The Raspberry PI foundation has release and micro controller called the “Pico”.  What is the difference between a micro controller and a micro computer is that is has no operating system.  The code is loaded into the processor and it run just that one program 24 hours an day.  They are mostly used in controlling device such as car engines, thermostats, dishwashers, and other singular device running a single task.

What difference with the device the the foundation created there own silicon processor the RP2040 which has its spec’s below.  The board has a USB jack built on top of it which if you hold down the button while plugging it in turns it into a USB drive where you can simply drag and drop your software into memory.

  • RP2040 microcontroller chip
  • 264KB on-chip SRAM
  • 2MB on-board QSPI Flash
  • 26 multifunction GPIO pins, including 3 analogue inputs
  • 2 × UART, 2 × SPI controllers, 2 × I2C controllers, 16 × PWM channels
  • 1 × USB 1.1 controller and PHY, with host and device support

The other difference is that like the Arduino it can run the “C” programming language it can also run “Micro Python” which is a subset of the Python language.  Micro Python is getting a very popular in the micro controller boards.  It is a higher level language that is easier to learn and to work with.  Below is an example of a Morse code program written in Micro Python which is only 53 lines long.  And some hardware to interface to your radio and it will transmit Morse code all day long.
