• The use of the DX Cluster spotting network is allowed during VHF contests
• Entrants may spot their own station on the DX cluster. Self-spots may be made when first soliciting QSOs on a new frequency and thereafter no more frequently than every 10 minutes.
• No attempt should be made during the QSO to obtain any part (including asking for a repeat or conformation of information) of the required exchange information via other communication methods such as the Internet chat channel, DX Cluster, talk-back on another amateur band, telephone etc.. Any such attempt to use other communication methods (internet chat, DX Cluster etc.) invalidates the contest QSO.
• Acceptable Examples when using chat or any other communication methods:-
  • Shall we make a sked on 144.388?.
  • I have QRM, let.s move to 144.218 kHz and start again.
  • Nothing received, please try later.
  • Thank you for a nice QSO. Note: only after the QSO has completed on the radio
• Unacceptable Examples when using chat or any other communication methods:-
  • I need your serial number.
  • Please repeat all information.
  • I received everything OK
  • Please confirm , , etc..
