We have a comment - WSPR

| No Comments

Someone had posted a comment to this post about my building a WSPR antenna.  The antenna is actually for my WSPR beacon transmitter. I am using the desktop unit from ZachTek and been getting solid repeatable spots at 1,000 miles with the occasional spot up to 2,700 miles (Hawaii). The current antenna is just a 4' hank of wire hanging out of my 2nd story window. The antenna I am building is a vertical 20' non-resonant single wire using a 9:1 Balun transformer and ground to get the coupling a bit more efficient.

I am setting up a receiver (KiwiSDR) and will be using a horizontal 60' non-resonant single wire for that receiving antenna. Been playing with some SDRs already - have two cheap Chinese units and been running an SDRPlay for the last four months and just love it. All of the fiddly bits of circuitry are now done entirely in software.

More as I get stuff built and on the air.
