PE1ITR-6 RADIO PROPAGATION ALERT @ JO21QK


This system gives a radio propagation warning on VHF and higher when conditions are good from maidenhead locator JO21. Several different sources are monitored such as the DXCluster, FMLIST, Beacons, iono data, magnetometers. At present, the following warnings are supported: E-skip on 50, 70, 100 and 144MHz. Multi-hop Es or F2 on 50MHz. Tropo on 144 and 432MHz. Aurora on 50, 70 and 144MHz.
The core of the system is a MYSQL database. This database is mainly powered by the excellent live muf v7 software by G7RAU. On top of this a lot of home written software for analyses and the alert system.
Alerts are send by Email, SMS, Twitter, APRS, DMR and POCSAG 439.9875MHz.
The system has been continuously running since 2006. This system is not primarily intended to be a 24/7 service for others, but it's more for me and friends to gain more understanding of radio propagation and fun working DX on VHF. If you want to be on the list for an alert message by email, aprs, dmr or pocsag pager this is of course possible. Please send me an email. Note: The best way to work DX is ALWAYS to be qrv.....
