5MHz operation

Some years ago I tried WSPR on this band. 

As I recall I used the coax up to my 2m big-wheel antenna and a mains ground. It worked and I got quite a few reports. The auto-ATU in the rig was used to match the random antenna.

Unfortunately, this part of the spectrum is controlled by the military in the UK. As a result, the UK has a fragmented set of allocations and has never adopted the WARC allocation. Although we are allowed more power and more spectrum, I personally would prefer a contiguous, if narrower, allocation at lower power.

To me, it is all too confusing. I suspect many do not use the band because they are confused by the allocations. There is a band plan on the RSGB site.
