Source: Base Esperanza – Antártida

Many thanks to SWLing Post contributor, Harald Kuhl, who notes that LRA36 (Radio Nacional Arcángel San Gabriel) has published the following new email address to be used for reception reports: tranalra36@radionacional.gov.ar

Thanks for sharing this Harald as I have not had luck with the former email address. I’ll re-submit my last report!

LZ1AQ Evaluates Impact of the Height Above the Ground on Mag Loop Performance

Source: LZ1AQ

Many thanks to SWLing Post contributor, Harald Kuhl (DL1AX), who shares the following article on LZ1AQ’s website:

Published on: 2018/11/20, Rev. 1.0 July 2018, Rev. 1.1 Nov 2018

Author: Chavdar Levkov LZ1AQ

Setup

Two identical small loops were placed one above the other according to Fig.1. One of the loops is very low – almost on the ground. The other one is placed at height which usually is used by the loop users. Two AAA-1C wideband active antenna amplifiers were used. Their gain difference was not more than 0.3 dB. The feeder was FTP cable each 20 m long. No cable baluns were used. The outputs were connected through two way antenna switch to a SD RX (Perseus). I used a measurement technique described in – A Periodic Switching Technique to Compare Receiving Antenna Performance in the Presence of Strong Fading. This is a precise method to compare two receiving antennas with real sky wave signals and the resolution can be less than a decibel. The idea is to switch periodically between two antennas and to estimate their difference on a calibrated graphic strength meter of a SD radio.[…]

I’ve often assumed height had little effect on the performance of an HF loop antenna–this evaluation seems to support that theory. Thanks for sharing this, Harald!

Armed Forces Day Annual Cross-Band Test – May 11, 2019

(Source: USAmyMARS.org via Harald Kuhl)

(11 May 2019)

The Army Military Auxiliary Radio System will host this year’s Armed Forces Day (AFD) Crossband Test on Saturday May 11, 2019. This annual event is open to all licensed amateur radio operators, and will not impact any public or private communications. For more than 50 years, military and amateur stations have taken part in this event, which is only an exercise scenario, designed to include hobbyist and government radio operators alike.

The AFD Cross-band Test is a unique opportunity to test two-way communications between military communicators and radio stations in the Amateur Radio Service (ARS), as authorized in 47 CFR 97.111. These tests provide opportunities and challenges for radio operators to demonstrate individual technical skills in a tightly-controlled exercise scenario that does not impact any public or private communications.

Military stations will transmit on selected military frequencies and will announce the specific ARS frequencies monitored. All times are ZULU (Z), and all frequencies are Upper Side Band (USB) unless otherwise noted. The frequencies used for the test will not impact any public or private communications, and will not stray outside the confines of the exercise.

Additional Information is provided on the 20190424-AFDCT-final.pdf file available for download [by clicking here].

Each year on February 13th UNESCO celebrates World Radio Day (WRD).

The WRD 2019 website will give more information about this years event in around two days from now:

Many thanks, Harald, for spreading the word! World Radio Day is a great reminder of how important radio still is in many parts of the world.
