Results of my recent experiences with various receive antennas for the LF and HF bands. Low noise with good SNR characteristics. Preamps and switching options. Bandpass filters and SO2R. Details of my latest delta loop designs can be found on instagram @vk6lw

2ele over 2ele stacked X beams for 20, 15 and 10m. EZNEC modelling, design, switching, results and conclusions.

BERU Commonwealth Contest 2024, wrap up, band conditions and observations from my operation as VK6T

Steve VE6WZ shares his thoughts on beverage antennas and explains the interesting development, improvement and detailed evaluation of his new BOG/BOL for 160m. For more information check out his YouTube channel @VE6WZ

This first episode for 2024 is mainly about CW and some history of the various Morse keys and paddles I’ve acquired and used over last 50 years

After some tower problems I designed and built a new X Beam with stacked elements 2 over 2 on my second tower. Intended to use this for CQWWCW…however some problems with 80/160 prevented an all band effort this year. So it was just 40m single band for me. See more on instagram @vk6lw

Review and discussion of the recent BERU Commonwealth CW Contest. Conditions on LF and HF, report on various antennas we used and tested both for TX and RX. Merits of SO2R in this contest, activity, HQ stations and travellers.

Wire Beams for receive and transmit. SO2R with RX bandpass filters. Single mast beam for 40m with relay switched elements. Commonwealth contest. WPX CW contest. IC 7610 Screen problem. Tower and new shack project.

CQWW CW contest, SO2R operation, improved HF band conditions. Improvements to LF and HF antennas, new directional 160 and 80 m antenna. RX antenna options

Summary of recent WPX CW, Rx antennas for HF bands, SO2R training and contest setup. 160m season and antenna evaluation. IC7610 and TS590.

Summary of the recent 160m CW contest. Band conditions from VK6.

Preview of CQ 160m CW contest this weekend. A perspective from VK6, this is a great opportunity to work some DX on Topband as activity levels should be very good.

CQWW CW condx and report. Low Band condx and antenna experiments and performance. SO2R setup, upcoming Commonwealth Contest.

LF Antenna Design with results of on air Tests on 160 and 80m. Upcoming CQ WW CW contest, HF Band conditions.

I visit the Ham Radio Show, Friedrichshafen, located in beautiful Lake Constance region. Fantastic 3 Day event for anyone interested in any aspect of Ham Radio. A great opportunity to try out the latest gear and find bargains in the massive flea market. WAE CW contest this weekend and general comment on band conditions from VK6
