Working POTA: A beginner’s guide and video

 

SARC in the park!

We had an interesting workshop on Saturday, September 16, 2023.  'SARC in the Park' was a presentation by Dmitry VA7DVO for our members interested in POTA activations. You will find more about getting started in POTA at their website, and in our free digital magazine 'The Communicator'.

With an easy to build and inexpensive segmented 5-band wire dipole antenna, we made several of the 17m SSB POTA contacts shown in this video, including Switzerland, Italy and with a mobile station in Northern England.

The antenna plan is at: https://bit.ly/SARC23Sep-Oct on page 45.

Lee will huff and puff…..

 


Greetings from Atlantic Canada, seems we are in for our first major storm this summer from the unfolding hurricane season. We moved to the Maritimes almost 5 years ago and before that time I only had seen reporting on the news regarding hurricanes. Since we have lived here we have had 2 and the first one was only after 2 weeks of living here.......that should have been our sign! But we love it here, the lifestyle, the ocean, the clean air and so on. We are gearing up here for Sunday's arrival of Hurricane Lee, the winds in this area are now forecast around 100 km. That is enough for me to remove the Hustler 4BTV and store it in the shed, put away the patio furniture, take down all hanging plants and anything else that may blow around. We have a generator back up at our home so a power interruption will only be temporary. As you know I am a big CW contesting fan and thank goodness there is no major CW contest this weekend....BUT.......if there was I still have the EndFed ready to go and that would give me my contest fix!
