Some of you will have noticed that the Sandton Amateur Radio Club 2 meter repeater, operating on 145,700 is giving static noise, especially in the winter in morning. Henry, ZS6MC together with ICASA investigated the RF interference on the 145.100 input frequency on the tower where our Antenna is located and did not find any immediate sources of interference. We suspect that interference is due to tropo-ducting from a distance source.
To increase usability of the repeater we will implement a 88,5Hz subaudible tone on the input channel as of 10 September this year. If you are a frequent user of the Sandton repeater you should program this tone already into your radio now.
