Re: LF: A 73kHz allocation again?

Hi Roger, Andy, LF,

Roger, that sounds a great idea, I was sorry to have missed out on 73kHz as I only "found" LF when that band was due to be closed. I can't remember what (if any) reason for the closure was. Of course I did get on 137kHz & I have enjoyed & benefited from the learning curve & operating there.

I hope you will get others supporting the idea. I think in my small back garden I am going to have great difficulty in radiating a signal over any distance more than a few kms.

Sold the old 73kHz loading coil at FR Hamfest last year :-)

 

But yes.   73 was more interesting that 137 turned out to be, whilst not being impossible to do something worthwhile for everyone who managed to get on.

All,

Looking at recent plots and listed VLF/LF stations active there would appear to be room in the 70-74kHz region for some amateur activity in Europe without risk to other services. I wonder, seriously, if we asked OFCOM (and other authorities in Europe) for NoV access to the 73kHz band whether it would be granted. They were helpful and supportive with regard to 8.7-9.1kHz NoVs and seem to accept that genuine research activities warrant support and encouragement. After all, only a handful of people would be interested.

With the progress in weak signal work since the 73kHz band was last available in the UK and with the new experiences of some at 8.97kHz (and 136kHz), there is surely a good case to support this as an experimental allocation via a NoV. I'd be keen to try earth mode and radiated tests (locally) at 73kHz.

What do people think? Should I ask OFCOM like I did for the Dreamer's Band NoV and see what happens or should this be via the RSGB?
