This followed a request at the September Forum meeting and was backed up with a short paper issued to them at the end November. =20 Apart from requesting a further year's continuation of the NoV I have asked if it will be possible to increase the ERP to +10dBW in order to bring it in line with licence conditions in some other countries. =20 Ofcom will obviously need to consult with the Maritime and Coastguard Agency (MCA) and were asking questions about the coverage at this higher ERP level. They were also asking whether we would accept a tighter definition on transmit bandwidth. This is to be more assured of not causing problems to services within the Maritime Mobile band 505 - 510kHz and I guess for the NoVs to be more compliant with the Radio Regulations footnotes 5.82A and 5.82B for 495 - 505kHz. =20 Getting a higher ERP limit will not necessarily be to everyone's liking, however, it may help investigation of the deep fades and also help those in high noise level environments. The ERP level and transmit bandwidth will probably be negotiable, but my aim is to achieve maximum flexibility in use of telegraphy and the narrower digimodes. Would 200Hz be sufficient or would we need a little more? Assuming that MCA approve of continuing the arrangements Ofcom indicated that their preference for extending the NoV would be as last year. This is to issue new NoVs to existing holders, anyone who no longer needs their NoV can return the documents. =20 Comments appreciated, either direct of on the reflector.
