Interesting resources provided here includes, Solar images, a text 3 day solar geophysical forecast, a 3-days Solar X-Ray flux plot updated evety 5 minutes, The Satellite Environment Plot, combines satellite and ground-based data

VHF/UHF Propagation - In the past few years there has been a growing movement from VHF frequencies (50-300 MHz) to UHF (300-900 MHz). Many, however, have found the move fraught with difficulties.

IPS - HF Systems MUF maps and prediction charts - These pages provide general propagation advice for HF communicators. Information available includes inferred global propagation conditions, real time HF fadeout coverage charts, regional ionospheric vertical MUF maps and Hourly Area Prediction charts for Astralia and Asia, Europe and North America

Radio Sport Canada Zone to Zone propagation - ZoneProp produces a 40 zone by 40 zone matrix that is updated hourly at approximately 20 minutes past the hour. The intersection between a row and column gives the band on which a constestant in the zone represented by the row is mostly likely able to contact an contestant in the zone represented by the column.
