First USA 10m WSPR spot today

KK1D (5455km) was the first USA station to spot my 10m WSPR today at 1258z. There will be plenty more today! FR1GZ has spotted me 4 times already.  K9AN (6505km) was the next USA station to spot me on 10m WSPR. Today, 10m is in very good shape.

UPDATE 1605z:  VE3GEN (5593km) has been spotted several times.

No longer tell XYL about DX reports on 10m

As I get so many DX reports with my 500mW WSPR, I no longer tell my XYL. An Australian station was spotting my 10m WSPR again today. I think this is the 6th or 7th time this autumn.  With WSPR and a very modest, low, wire antenna I find DX easy. With SSB or CW you are competing against the "big boys".

10m has been good now for about 4 years. This time next autumn things are likely to be much harder. Sunspots are still high but this time next year they are likely to have fallen a fair bit. Somewhere I read that a solar flux of over 100 equated to "good conditions".  It is more likely solar flux will be in the 70-80 region next autumn.

The greatest danger is low activity on 10m as people leave the band for lower frequencies. Many times I have said this will be when 10m WSPR should be really useful winkling out those elusive DX openings. Please, still use 10m WSPR even when the band seems dead. I am convinced it will be "open" far more often than people realise. WSPR is so much better than SSB or CW. Using WSPRnet, you can instantly see who is copying your WSPR signal. Low power is all that is needed.

UPDATE 1254z:  I see that FR1GZ (9724km) has spotted me on 10m WSPR. This is no longer remarkable! WSPR really is amazing  - just 500mW to a low wire antenna. On SSB it is a battle against those using big beams and high power.  On WSPR just a few milliwatts and you can find out how your signal gets around the world.

UPDATE 1530z: VE3GEN (5593km) was spotted several times today.

Loft trawl - lost amateur gear

It is now 22 months since I was discharged from hospital following my stroke. I have yet to get into the loft to properly explore the things I put there when we moved QTH over 2 years ago. My problem is ladders, although I am getting close to getting up there to have a good rummage around the boxes!

As I recall there were quite a few boxes with odd pieces of amateur gear, although these were mainly wires, SMPSUs and the like - nothing of value. You could well argue that if I have managed without these for over 2 years then they need a new home and certainly I don't need them. Maybe the next junk sale or rally?

Sunspots and 10m - Sun Nov 22nd 2015

Sunspot number has risen a little to 59 (K=1) but solar propagation predictions for 10m have improved to "fair". Solar flux today is 121, which is not at all bad.

UPDATE 1000z:  VK2KRR (16789km) has already spotted my 500mW WSPR beacon 3 times on 10m. Today is going to be a good day on 10m WSPR. I feel it in my bones!

UPDATE 1006z:  All quiet so far on 6m WSPR here with no spots yet given or received.

UPDATE 1010z:  As the above reports indicate, I went QRT on MF at breakfast time and am now active on 10m and 6m WSPR for the day.

QRP on Wikipedia

This link has been posted before but it is worth repeating. This is the Wikipedia link all about QRP.

See https://en.wikipedia.org/wiki/QRP_operation .

I am a firm believer in QRP. Simple gear can span the globe, although rising noise floors are making it tougher for some, especially in cities and towns. In theory, 5W is just a few S-points down on a 100W rig, but these days the limit is more likely to be man-made noise sources at the receiver especially on LF, MF and the lower HF bands. Up to now, I have been blessed with a low RX noise floor here. I am still lucky.

A second chance - NOT amateur radio

USA spots on 10m

K9AN (6505km) was the first USA station, and so far the only one, to spot my 10m 500mW WSPR this afternoon at 1418z.

UPDATE 1540z: Still just K9AN spotting me on 10m in the USA this afternoon.

UPDATE 1715z: In the end I got spots from 4 different USA stations on 10m WSPR. I have now gone QRT on 6m (where G8VDQ at 93km was spotted a few times) and on 10m WSPR and am back on 630m (472kHz) WSPR for the evening and night (5mW ERP TX 20%, 80% RX no preamp). So far, on 630m G7NKS (46km) has been copied at -11dB S/N. Still using the earth-electrode "antenna". G7NKS copied me at -22dB S/N. Also copied on 630m WSPR was DK7FC (669km) at -25dB S/N.

No snow - NOT amateur radio

We seem to have missed the snow. Although there is a biting cold north wind, it is dry and the sun has come out. It would not surprise me if we got a frost tonight. This would be the first time this autumn. Up to now it has been very mild.

This afternoon, a walk is called for, although we will have to dress in warm clothes!

UPDATE 1540z:  We walked around the village.

Sunspots and 10m - Sat Nov 21st 2015

Sunspot number is 52 (K=1) and 10m conditions remain "poor" according to the forecasts. Solar flux is a respectable 111. Often I find I get good 10m WSPR spots when conditions are supposed to be "poor".  Not sure why this is!

UPDATE 1204z:  So far, just spots from Russia and nearby areas on 10m WSPR. No great DX on 10m WSPR as yet. All quiet on 6m WSPR.

In praise of Jay W5OLF's WSPR beacon

I received this email from Jay W5OLF:

"Hi Roger,
I was catching up on your blog and saw the comment about how much you like the 10M beacon. That warms the heart.  We all try and make a contribution to the hobby and guess I at least made one.

Cheers, Jay, W5OLF"

W5OLF WSPR beacon
To which I replied, with great pleasure:

"Hi Jay,

I can honestly say I have had more fun from your 10m WSPR beacon than from ANYTHING in all my time in amateur radio. Thank you!

73s
Roger G3XBM"


I was an SWL in 1961 and had a licence since 1966. The beacon needs no PC and is totally self contained. As a routine I reset to internet time every day but you could use a radio for this and once a day is probably far more frequently than necessary.  As you can see, it is very small. The last time I looked there were 1W beacons for 30m and 20m and a 0.5W one on 10m. If you enjoy this mode, I can recommend these. It never fails to amaze me how something so small to a small, low, wire antenna regularly gets spotted around the planet.
