Hi Peter (and all LF)

My point on WSPR is a serious one and I think you've either not followed my logic or understood how bandwidth efficient WSPR is.

Let me spell it out again...

Within just 200Hz of the band >100 stations can happily coexist and still leave ALL of the remaining band for good use by stations wanting QSOs (rather than beacon type experiments) using whatever narrowband mode they choose. This is excellent use of precious spectrum and beats anything else for "experimentation and self training per Hz" by my book. 

I have every wish to enjoy the rest of 500Hz as well, but find the small slot for WSPR a valuable use of the band in a way very much in keeping with the aims of our ham licences. Also, with WSPR high power is not necessary, so interference and coexistence issues should be perfectly manageable.

Hi Roger and LF

 

1/ 10Mhz is a totally different situation to the 500kc/s allocation and can not be compared. Its like comparing Apples and Bananas. It's a wide band compared to 500 and has very short ground wave. Mostly propagating via sky wave so the issues we see on 500 just don't apply.

 

2/ The Sideband beacon transmission from one of the EU "Vanity" stations HF of the British experimental and research allocation does not have any real impact on the British allocation as far as I can see so it is a non issue IMHO although its purpose is slightly beyond my Neanderthal brain.  

3/ We should all be nice to each other?.... The Third Man was on TV over the week end and .........  

 

Harry Lime said .....  "In Italy, for 30 years under the Borgias, they had warfare, murder and bloodshed, but they produced Michelangelo, Leonardo da Vinci, and the Renaissance. In Switzerland they have brotherly love. They had 500 years of democracy and peace, and what did that produce? - The cuckoo clock!"  

 

Think on!

Mal,

Some suggestions:

1. More people should use WSPR - lots of stations (more than 100 at a time based on 10MHz usage) are able to operate together within just a 200Hz slice of the band allowing very useful data on propagation and station performance/changes to be determined.  This would leave plenty of room elsewhere in the band for CW and other narrowband conversational modes.
2. Occasional testing with SSB, for those allowed to use it (not UK), is of interest to me as a listener, but I agree that it's not a good idea to use this mode when the band is open for really long-distance DX if interference to weak signals is likely.
3. You should try a New Year resolution: "I will be more tolerant and moan less".
   

73s and a happy New Year to all on this reflector

I am afraid we have a SSB beacon on 508 kcs spreading over 3 kcs wide and S9 plus with me. Beacon SM6BHZ is causing QRM to those of us trying to listen and work the East Coast USA stations. I cannot understand why a station is licensed to work SSB in such a narrow band allocation.

The 500 kcs band is a Shambles swamped by beacons.

Does anyone else have an opinion?
