Learn to Pass ARRL Radiograms
ATEN has been operating daily since the beginning. There have been times when the net was very busy handling traffic. The net meets each day practicing the passing of formal written Radiogram Traffic messages into and out of our coverage area. We have a great bunch of people that make up the Net. We practice every day for that emergency which we hope never comes. Visit https://www.atenaz.net/ for more information or listen in on 3986 kHz at 5:30 PM MST or 0030Z daily October 15 through April 14 or 7:00 PM MST or 0200Z April 15 Through October 14.
How to be a ham radio operator during public service events and nets
Daily Propagation Activity Net
There is a rather informal Activity Group that meets on-Air daily. This is an awesome resouce for testing out new gear, espcially antennas and microphones.
The idea is to check-in so they get you on a list. Then each station is called to make a CQ call and all the other stations, that hear it, will respond with a signal report. Every ten minutes they do an ID call so it is a chance to jump in if you are late to the party.
The daily schedule is:
- 17 Meters: On or about 18.1575 MHz starting at 17:30 UTC for approx. 1 hour
- 15 Meters: On or about 21.383 MHz starting at 18:30 UTC for about 30 minutes. If You hear Roger (ZL1XR) in New Zealand, sometimes he sticks around for QSOs afterward.
- 12 Meters (if conditions allow): On or about 24.970 MHz for up-to 30 minutes. Then, if conditions are really good,…
- 10 Meters: On or about 28.420 MHz for as long as necessary.

End Fed Half Wave Antennas (EFHW)
Interest in the EFHW antenna has sky-rocketed over the last few years, and like many topics under the heading of antennas, accuracy of information can vary.
The following website(s) may help to clear up any questions or confusion about cores and winding ratios.
