VHF activity on the increase


Several amateur radio operators in the Johannesburg and Cape Town areas have started to experiment with SSB on 2 meters.
Recently they decided to also use 144,200 MHz SSB as the country-wide calling frequency. This frequency has been in use for a number of years by division 2 and 5 stations and many contacts have been made on SSB.
If you are only equipped with FM then try 144,400 MHz the FM DX channel. Very long distance contacts have been made on this frequency from the east coast of the RSA to Reunion Island on both FM and SSB and over land from Richards Bay to Port Elizabeth.
Amateurs in Port Elizabeth monitor this FM channel from 19:30 CAT until 20:00 CAT for stations in Mosselbay and East London. At 20:00 CAT they change frequency to 144,200 MHz SSB for longer distances to Durban and beyond.
Likewise there has been a revival of interest in the 6 metre band too. Quite a number of stations became active again in Cape Town, Johannesburg, Durban and Port Elizabeth using the frequency of 50,200 MHz SSB.
To get the best long distance results on VHF you should use around 100 Watt and a high gain horizontally polarized Yagi beam antenna with a LNA.
