Best WebSDR Servers:
Thanks to Skywave Linux for listing this WebSDR as one of the best WebSDR Servers. https://skywavelinux.com/best-sdrservers.html

Current WebSDR Schedule:
9AM-7PM US Central Time - High Bands - LW/MW + 90M-75M + 40M through 25M
7PM-9AM US Central Time - Low Bands - LW/MW + 90M through 31M


ANTENNA CHANGE:
As of 04/06/2018 the HF Bands 90M-up are now on a 50ft Horizontal Endfed @ 45ft. The Feedpoint is NNW, the Far-End is pointing SSE. This should improve reception, especially at Night for the Lower Bands.

THIS STATION (KF5JMD) Transmits on HF Bands in Digital Modes (FT8 mostly). Expect Desensing and Interference to this WebSDR Server while this Amateur Radio Station (KF5JMD) is Transmitting!
