When we teach our Technician License class, we normally differentiate between HF and VHF propagation by saying that HF often exhibits skywave propagation but VHF is normally line-of-sight. For the beginner to ham radio, this is a reasonable model for understanding the basics of radio propagation. As George E. P. Box said, “All models are … Read more

I am recovering from a knee injury so Genesee Mountain (W0C/FR-194) turned out to be a nice easy hike for me. Of course, Joyce/K0JJW joined me and also did a SOTA activation. Caleb/W4XEN came along with us … Read more

Rather than spend a few hours in an airport, we decided to spend a day or two in Switzerland. Somehow the discussion turned to Summits On The Air (SOTA) and whether … Read more

The SOTA database (W0C/SP-127) says the name is Mount Emma but all of my maps indicate that it is Emma Burr Mountain. (I contacted the W0C Association Manager and we’re working it out.) Joyce/K0JJW and … Read more
