    Hi all!

    As a fresh capespectrum.wordpress.com user i just wanted to say hi to everyone else who uses this board 🙂

    I also like this website. I’ve battled to find frequency lists (for HF, VHF and HF) for South Africa on the net. Radio scanning has been one of my hobbies for years, and have recorded hundreds of frequencies, especially for the Gauteng and Durban areas. Will post up some of them sometime.

    There is some illegal radio communications on the radio amateur band by some yacht owners on 7007 and 7001 USB, Gavin and his friends , swearing a lott. can anyone listen and report who they are.

  6. ZR4LP Says:

    They are on the common wealth Tuna vessel

    • Johan Says:

      They are NOT yacht owners.
      Yacht owners (or crew) dont sit on radios and swear; they sail their yachts.
      These are fishing operators and known for their foul language on the air.

  7. Phil Sorensen Says:

    I have noticed that there is a transmission on 7100kHz in the 40m amateur band from 05:00 to 07:30 GMT with a 59 carrier with periodic bursts of RTTY then ID callsign ZSC. At first I thought that one of my radios had a problem, but my other radios hear the same signal. I use a Kenwood TS530S and a Kenwood TS50S. This has been confirmed by another ham in East London. Is it possible that one of your coastal HF transmitters have gone spurious? I know there is a relay station just up the coast from East London towards Durban, but that is VHF. It would be appreciated if you could explain where these transmissions are coming from.
    Many thanks,

    I have spoken to CT Radio this morning (Sat 19 Feb.) and there was no “technician” available but the operator will inform them on Monday.

    He confirmed that they do not transmit on 7.100 and that the same has happened in the past on other non-marine frequencies.

    The RTTY+ CW sounds like their HF Autolink channels ID (such as at 4.363 kHz and 8.725 kHz both USB).

    Here in Milnerton the carrier is 59 + 30 and the signal is 59 + 60dB (full scale on my IC-746) and I am 1.35 km due West from Cape Town Radio and their antenna farm.

    At that level the signal is definitely from this site. Also I am still receiving the signal every 4.5 minutes at the moment and it is already past 12 noon.

    For your Google Earth info their site centre is 33:52:45 S by 18:30:22 E and my location is 33:52:49 S by 18:29:29 E.

    I’ll let you know should there be any response from them.

    With all my dealings with them (marine) I have never been disappointed by them.


  9. RF Says:

    I thought that the Marconi Beam site was receive only and the TX is from KLIPHEUWEL no?

  10. Johan ZS1VU Says:

    No, the ZSC i.d. signal and for Autolink gets transmitted from Milnerton Marconi Beam site as well as marine VHF.

    There was a power outage (which affected myself) and when power came back on that particular transmitter defaults to 7.100 kHz and there it was merrily sending its signal on our 40m band.

    They have now installed a UPS for that Tx and will also change the default to the intended operating frequency.

    Some fishing boats skippers chatting on 7.749Mhz , blimey good signals from the vessels.

    I am in Nelspruit so comms is super.

    Cape Town Radio Land mobile channels:

    TX frequencies (KHz)

    ZSC 4905 – Mobile 4817.5
    6852 6836
    8047 7610
    14887 13895
    14700 14585
    20390 20050

    If you have an account with telkom and a callsign, you can call on theses channels to get radio telephone patching

    Probably the 6 and 8MHz work best throughout South Africa.

    Listen on 8740 at 10:15 and 18:15 UTC to check reception

  15. Ean ZS1PR Says:

    The 14 MHz will be best during daytime for ranges in excess of about 1200 km from 09 GMT/UTC to late afternoon/early evening. The 6 and 8 MHz frequencies will cover the entire South Africa (and well beyond) at night.
