I often just cannot believe some things in this fine technical hobby of ours. The number of Luddites is amazing. Several groups have a loud, rude contingency who voice their hate of WSPR and all things Digital or involving a Computer. Most likely they sit at an immaculately tidy desk with one commercial radio on it with the power turned down (so they can say that they run QRP) and a Morse key.
Now one group has bowed to the Luddites and for all intents and purposes banned the mention of Computer related posts. I know there are other ways of looking at this, but this is my personal opinion on my blog. Heaven knows you dare not express an opinion within the groups, that is all they are there for it seems, snarling at each other and ridiculing someone who is new and having a go. The fellow I have in mind here has been remarkably polite and tolerant of his ignorant taunter, proving himself far and above a better person. Ha! I feel I may not have managed such politeness.
Can someone please start a group for the Narrow Minded and send them all there.:yawn:
What can you do with WSPR on 500KHz that you can’t do on the key was one subject. “Well get a proper report in 2 minutes having made Antenna changes, how many CQ calls on the key would it take before I got a reply to my signal that as yet has never been reported as being heard?” How meaningful would that report be, I listen to a few Morse QSO’s on 500K and yep the reports both ways are normally 599.
Likewise who is going to sit throughout the night giving me reports on my signal, even if I was prepared to send a CQ or TEST every 10 minutes.
I added the disc Capacity Hat to my 500KHz Antenna to see what it would do in practice. In theory it concentrates the Current higher in the Vertical section and is the aim for most stations on 500K. I am sure it has done as expected, however the current high then is closer to my Mast and VHF antennas which are far taller and well earthed. Absorption therefore could cause attenuation of the signal. My reliable daytime path to M0BMU vanished to be replaced by M0WQR.
Another new reporting station and No.6 for me.
With so few stations on 500K WSPR it is surprising that I have yet another 2 stations who are equidistant, within 1 Km which makes things interesting.
So why the difference in received signal? I suspect that as M0BMU is a TX station on 500KHz, his Antenna will be mainly Vertically polarised. M0WQR however is an RX station, maybe he has more Horizontal response from a more universal Antenna, my inv.L has some horizontal component for sure.
The darkness path to M0BMU was fine on 29-12-2009, I awaited the ‘switch over’ last night. Unfortunately M0WQR literally switched off around 21.00 but as can be seen, the path to him faded around the onset of darkness. M0BMU came up around 22.00 then was solid from 02.00.

Varying conditions of course play a part so I shall leave this Antenna set up for a while.
Variable conditions it seems to have been, how typical after an Antenna change. M0WQR has not been RX’ing again, I don’t know how is one supposed to do tests :DD. M0BMU is back day and night with maybe an improved report.
I had no intention of trying to join the big guns on 500KHz, it seems there is no chance anyway. Any move I were to make to my Antenna would merely serve to bring the Vertical section nearer to yet another absorber. I have the 6m Mast that supports the far end of my 6m high 500KHz Inverted L, not to mention the aluminium greenhouse in front of it. A 6m Vertical Antenna to the right. My 40m Doublet 6m high to the left and the VHF mast with beams behind. Off the ground wall mounted Top Loaded Verticals are out,(no room). It is a case of how much of my tiny power level can I get out of a Faraday Cage.
