WSPR Under Threat?

The removal of allocation from VHF has come as no surprise. It may well be the case, as some suggest, that it can continue regardless of band allocations. However if the menus for those bands are removed from WSPRnet then it would become problematic. My view is that pressure will be brought to bear to make this happen.

Hello and thanks for reading.

Perhaps this has already been addressed, apologies if I missed it. We have Wspr-2 which I find covers most requirements from 630-10m. There is also Wspr-15, I have tried it too. Also there are other modes for MS etc. All great.

I know there are other data modes developed for VHF and above. But as far as I know - I am quite dim at times - nothing specifically for VHF in the Wspr pallet. The kind of thing I would envisage is a wider band shorter burst version of, say, 30 seconds.

Am I the only person who found the article in June 2013 Radcom by Andy Talbot strange. If I didn't know better it might have come over that some people have an agenda against free experimentation.

The article made certain assumptions about the (implied) misunderstanding (we are wearing the wrong trousers apparently) of operators on bands above HF. What if the operators already knew and understood the issues raised, but wished to experiment regardless?

When I obtained my license it was with the understanding that we would use it for experimental purposes.

Spurred on by VK2UB's page (cheers Gordon!) I finally got round to initializing my own here: http://www.qsl.net/g0mji/Grab%20Page.html
A great idea which could be incorporated into the Wspr program/site as an option?

If it isn't updating I am either off air, or it crashed.

If there is nothing to see, well that's 4m Wspr for you.


I have put together some things I have noticed about using Wspr on 4m here:


Now that 4m is on the map it would be good to spot and be spotted by new stations.

Yesterday was a good day for 4m Wspr: Stations in Essex, Northamptonshire, Merseyside, Greater Manchester and Cumbria were spotted, or spotting, on the band. The four metre Wspr database runneth over!

I will be on air every evening whilst the radio works, usually between 5-9pm for anyone who wants to try. Generally pointing South-East towards the continent (anyone out there?) horizontally polarised. I can switch to vertical given notice.

While I have had some support in the attempt to get Wspr going on 4m I have to say there seems to be some antipathy towards the mode on there. Here's one on The Four Metre forum:

''I'm not surprised at all that there is an absence of spots in the database.
In the first instance very few operators will know that you are 4M-active.
