03/26/2020 If you cannot get any Audio, USE FIREFOX BROWSER INSTEAD!, it works best with the WebSDR Server software. Enjoy. KF5JMD

09/01/2020 Fixed Frequency Alignment on 80M/40M and 9/10Mhz Bands. May need adjustment again in a couple months when Weather gets really cold. Should be good for a while. KF5JMD
