in Belgium we have access to 500kHz since about 1 year.
Conditions (limitations) are:
- max. 5 W EIRP
- only telegraphy
- max. 100Hz bandwidth
- only full license holders
ITU Recommendation R V.662-3 defines telegraphy as "A form of telecommunication in which the transmitted information is intended to be recorded on arrival as a graphic document; the transmitted information may sometimes be presented in an alternative form or may be stored for subsequent use.". So digital modes could be considered telegraphy and thus allowed on 500kHz.
As we (UBA) reached the 500kHz access only after long negotiations with BIPT (our Ofcom / FCC) we are very careful in what we do. Therefor we asked BIPT if they would agree with our point of view.
After internal (read BIPT legal department) consultation BIPT agreed with us.
So from now on we can use digital modes on 500kHz. The 100Hz bandwidth limitation is still in force, but there is plenty of digital modes that stay within this limit.
