At the SNBCG operating site we have the opportunity to out up some large antenna, and for some time we had wanted to try 472 KHz using George M1GEO WSPR transmitter. The plan was using the onsite 50m cellphone mast* to pull up some wire, and with some work hopefully, enough wire to have a […]
How good is that choke?
With field days just on the horizon, I decided to make a couple of Balun (common mode choke) for field day use. I often use a vertical for 7 or 3.5 MHz, and a 1:1 choke is needed to stop the feeder becoming part of the antenna system. Sure you can purchase them online, but […]
