Antennas

This is a huge topic for Amateur Radio operators. As we find and develop materials we find useful to our members, we will be adding them to this section of the website. We have some antenna expertise in the club that we hope to share through this forum.

WSPR Weak Signal Propagation Reporting

Weak Signal Propagation Reporting (WSPR) is a technique for using very low power beacon transmitters to test antennas and propagation. WSPR implements a protocol designed for probing potential propagation paths with low-power transmissions. Transmissions carry a station's callsign, Maidenhead grid locator, and transmitter power in dBm. The program can decode signals with S/N as low as -28 dB in a 2500 Hz bandwidth. Stations with internet access can automatically upload their reception reports to a central database called WSPRnet, which includes a mapping facility.

Check out the presentation from Tim (KJ4RDF) in 2021, that covers all the basics. This can be found on our Meetings page under Technical Programs.

Track your transmissions on WSPRNet website.  LINK

Echolink

EchoLink® software allows licensed Amateur Radio stations to communicate with one another over the Internet, using streaming-audio technology. Many repeaters, including our club repeater, are equipped to connect to the internet and be used by EchoLink®. Using this capability you can use a portable platform like iPhone or Android to connect to hams all over the world, or just to check in on your local nets on your linked repeater. The software is free at www.echolink.org .

Digital Modes

Digital modes become increasingly popular with ham radio operators. Explore these pages and understand how digital radio works, why it is popular, and how to get involved.

Grounding and Bonding
The net on 11/3/22 had many questions on grounding and bonding. It is a complex topic with many opinions. The suggestion is to view this great presentation by Ward Silver (N0AX). He is the recognized ham radio expert on this topic. Here is the link to it:  LINK

Microcontrollers for Amateur radio projects

Resources for using microcontrollers in your projects.

Satellites and EME


Some club members are interested in satellites and other  communication methods such as moon bounce sometimes called EME, for Earth-Moon-Earth. 

Want to work a satellite? It may be easier than you think.
What about moon bounce? How hard is this to do?

DIY Projects and Kits

HamRadio Workbench
This site has a specific section on DIY projects and work setups for DIY. Click the link below to go to their page.

We are looking at building the power control module starting in February 2018 and when circuit boards are available. Marty Buehring heading the project.

New projects coming on 2018. Follow the podcast for more details.

Build your own transceiver

General Coverage Receiver-Transmitter
Build the µBITX transceiver in an evening. A general coverage, 10 watts HF SSB/CW transceiver kit  with features you NEED for operating ease, convenience and versatility. It works from 3 MHz to 30 MHz, with up to 10 watts on SSB and CW, with a very sensitive receiver. It features digital tuning, dual VFOs, RIT, CW Keyer and more. Very "hackable" design you can customize.
Pre-order cost is published at $109.00 US

Club Designed Project

How would you like to be part of a project team to design, document, and build a project from scratch?

We have engineering skills in the club capable of doing this. It just needs to be organized.

What can you contribute?
