10-metre calling frequency28 MHz is an initial indicator for Sporadic E paths that may hit 50 MHz or beyond. Beacons in the 10 meter band can often identify high MUF clouds building over paths, it can be a good indicator of a high MUF out to further distances than your received beacon. One thing missing from 10 meters is a calling frequency on 28 MHz. Its a recognised fact by many, that a lot of operators sit on 28.490 MHz as a calling freq. But there are still many who disregard this and if they make a contact on it, they'll stay on it and cause chaos for others. So much so that the band is often a disgrace. Only this week, in a bout of 'sniffing around the bands', two Amateurs who obviously live by our "ham code" impressed our reporter. Leigh VK2KRR and James VK4XJB VK4XJB near Toowoomba, was calling CQ on 28.490 MHz. When VK2KRR responded, James was heard asking Leigh to QSY down to let others have a fair go on the calling frequency. Well done James! Its common sense and courtesy that, if you know others are going to be listening and calling and your going to be interfering, that you QSY. Maybe we should make Glenn Dunstan, our Wireless Institute of Australia Director who handles band plans, aware of this, with the thought of designating 28.490 as a band planned calling frequency. Food for thought?
