I've been actioned to prepare a draft. Grateful for detail of the spec that the Loran transmitters are expected to meet, any known precedent where in specific circumstances where this has had to be improved upon, and any view on whether the spurii is likely to effect other LF users (apart from amateurs). My intention, unless others have a better plan is to ask that additional filtering be incorporated and that aerial installations are carefully maintained to avoid the rusty-bolt effect. Can anyone comment on whether any other services within the LF spectrum area are likely to be effected, i.e. are we likely to be able to call on support from operators of other services? 73 John, G3WKL
