Electronic Communications Act, 2005 (Act No. 36 of 2005)ICASAFinal Radio Frequency Spectrum Assignment Plan for the Frequency Band 470 to 694 MHzAppendicesAppendix C : Interference Cases per Province |
DTT frequencies selected from 7 Mux plan to minimize interference on existing analogue. See sections on frequency assignments/allotments.
Easter Cape CH 46 - MUX 1
Interference Herschel CH46 SBC3 - Confirm "on air" Consider Herschel as priority area for Analogue Switch-off
Sterkspruit - Large power difference on adjacent channel 47 - ensure same TX power levels - This will resolve the interference
Aliwal North Goedemoed - Co-Channel on CH46 - switch over to satellite reception
Eastern Cape CH 35- MUX2
Despatch Adjacent Channel with Despatch CH34 - slight interference - ensure same transmission power - This will resolve the interference
Barkley East co-channel CH 35 - slight interference - Increase the power on SBC1 Transmitter with 6 dB to overcome interference
Northern Cape CH31 - MUX 2
No interference predicted
Northern Cape CH24 & CH27 MUX 1
No interference predicted
Western Cape CH33 & CH38 MUX1
No Interference
Western Cape CH29 MUX2
Graafwater interfered by Piketberg - Graafwater Self-help viewers to migrate to satellite immediately
Northern Province Mux 1 & 2 Area A
No interference CH21 & CH33
Northern Province Mux 1 Area B CH26
No Interference
Northern Province Mux 2 Area B CH26
No Interference
Mpumalanga Mux1 CH35
Slight Interference Davel etv CH34 on outskirts (complementary coverage available) and Steelpoort
Legobo SBC3 Self-Help
Mpumalanga Mux 2 CH31
Light interference in Davel CH30 Coverage (SABC1)
North West Mux 1 CH34
No interference problems
North West Mux 2 CH46
No interference problems - Mux2 split not required
Gauteng Mux 1 CH 36
No interference predicted
Gauteng Mux 2 CH 44
There is some interference on the Potgietersrus etv transmission on CH44 near Nylstroom. Pretoria etv CH29 offer Complementary Coverage. Prioritize analogue switch-off in Potgietersrus coverage area near Nylstroom
KwaZulu-Natal Mux 1 CH 30
Interference on Maqabaqabeni SBC3 CH30 - Confirm "on air" If "On Air" treat as priority area for Analogue "switch off"
KwaZulu-Natal Mux 2 CH 40
No Interference
Free State Mux 1 CH21
Koffiefontein (CH21) SBC1, Phillipolis (CH21) SBC2, Marquard (CH21) SBC1, Manguzi (CH21) SBC1.
Free State
Grootvlei Eskom (CH25) SBC2, Marquard (CH25) SBC1, Manguzi (CH25) SBC1.
