My only observations about WSPR is that it is an Appliance Operator mode. Set it up go to work or go to bed and check a data base once a year or more often if one desires.
I personally do not need WSPR because I can get on a band and after a short observation make a decision whether the propagation at the time suits what I want to achieve and commence communications in real time. To find out later as in using WSPR is pointless because the opportunity has passed.
How would DXPEDITIOINS implement WSPR when one needs to know at a specific time when to engage a particular band to work particular countries in reral time.
WSPR is a store and tell  mode and useless except for those that want to fiddle with machines then leave them unattende and hope for the best
How did we professional operators manage communications and propagation this past 100 years without WSPR, and still do.
WSPR is a toy for those that fumble and get muddled  with CW and the only alternative is Mobile Phone, Internet or Wspr.

For those interested in Z codes

Seriously though Mal. You seem to be lucky enough to be able to devote hours of your day to policing the lower bands, and actually operating, which must be great.  Most of us have other things to do and some can contribute more by the use of innovative software and systems that allow automatic reporting of signals at levels comparable to or better than any human operator, without having to stay glued to the receiver.

I fully expect to be able to gather enough data from WSPR transmissions eventually to measure the movement and size of propagation 'zones'  and probably other useful data too. I don?t expect you to understand the technicalities, I have only a limited ability in this area, I find the maths hard, but then I am not a Nobel prize winner. There are those in our community who really do understand what the potential is and are working hard to realise it. 

The use of these modes and the potential benefits may be outside your interests, but have the courtesy to respect that others actively wish to use the band for genuine experimental reasons, rather that just operating. Some may not even want to have QSOs


FWIW, I am also a keen and fairly competent cw operator, perhaps without prejudices instilled by my profession, and I am able to operate and receive weak CW within tens of Hz of other transmissions. If you are half the operator you claim to be, you too will not be severely impacted by the usage of a small segment of the band by WSPR or other machine generated transmissions. 

A good proportion of my operation from 500KHz to 24GHz and even light, is on CW, and it has netted me more DX and first countries from GM that I can remember. However you will find me on JT65 and JT6M regularly on 4m and 6m as it is better for some of the propagation modes I am interested in.

I will be running up a WSPR transmitting station on 500KHz soon with luck, and will endeavour to provide the grabber and WSPR receive system, 24/7


There is room, even in the 500KHz band, for multiple modes and interests to be explored without significant conflict. Be happy that the band is being actively used.


You are not going to have regular QSOs with stations like me who want to experiment, as I am not often in a position to break out the key. When I do have time to operate, it is likely to be on CW, the WSPR system will be off and I hope to see you there!


Happy New Year

Mal - GROW UP.

This is fantastic news for the Appliance Operator. Follow a basic set up guide then let the unattended machines, all 200 of them growling away at each other at 2 minute intervals. Operator check data base once a year for possible hits.
I am surprised it is not more popular.
Over Xmas the bulk of activity was by Radio Operators on LF using CW and QRS plus some limited MF activity again using CW.

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?
