WSPRing on other bands

Today I ventured onto 60m, 40m and 20m WSPR for a change. A few spots out to 448km on 5MHz and plenty of EU spots on both 40m and 20m.

I returned to 10m to see what was doing.  At this time of day 10m is THE place to find stateside DX in abundance. Conditions like this unfortunately cannot last.

I have now decided to take a look on 136kHz with the earth-electrode antenna and the VERY deaf  FT817ND.  I might JUST be able to copy DK7FC and possibly G8HUH but I do need to make a preamp.

UPDATE 2025z: absolutely nothing copied on 136kHz WSPR. I need a preamp!

Last day on 10m?

It is probable that today will be my last day on 10m for a while as I am no longer gaining data by being active on the band. 500mW, even with my compromise antenna, is enough to be spotted all over the world. I may try MF again, 60m or even 6m for some TEP, although there is sadly very little activity on 6m in this part of the world.

Last night, my last spot with 500mW on 10m was K9AN  at 6505km at 2114z, along with others. I spotted other transatlantic 10m signals until 2134z.

This morning, my 10m 500mW WSPR is reaching LZ1OI and 4X1RF only - conditions seem less good than recent days. I wonder how soon transatlantics will appear today? Sunspot count is 137 and conditions stable - looks quite promising.

I notice that  EX1UN (5423km) was being decoded here as early as 0628z today. PA4PS (436km), in JO33 square, is being regularly copied, I presume by tropo or backscatter. My first USA report today (10m 500mW) was AI4RY at 1228z at  6931km.

10m - overwhelmed by results

Just 500mW on 10m WSPR seems to get spectacular results with the band in its current excellent shape. As conditions go downhill as we slide down from the peak more power will help, for certain.

34 unique reports at 500mW in the last 24hrs alone:

10m 500mW WSPR - 34 unique spots in last 24hrs

Good start on 10m this morning

Already, at around 0700z my 10m 500mW WSPR is being spotted in Reunion Is (Indian Ocean) by FR5ZX and in Israel by 4X1RF. I was spotting Japan at 0842z and there is plenty of good DX around such as TJ3 and EX1. Sunspot count is 125 and we can expect stable conditions according to the solar forecast. 10m should open to the USA and Canada from around 1130z to about 2145z. Yesterday turned out better than I expected. 10m is such an excellent and interesting HF band.

Some of my reports from the USA have been VERY strong indeed, even when running 500mW RF.  In some cases just a few mW would have been enough to get spotted transatlantic.

10m with125mW (Ultimate 3 WSPR beacon)

As you may recall, I am building an Ultimate 3 WSPR beacon for 10m as soon as I feel up to the task. Currently I am too clumsy building because of my stroke. The reports yesterday and today with 500mW on 10m suggest the majority of spots would still be achieved with 6dB less power, QRM permitting.

Just maybe I'll try the beacon initially at its 125mW design level.  I was intending to run about 2W pep finally.

My last 500mW TX burst on 10m (at 1634z)  just now got no less than 11 different spots, with all but one (IT9) being received from the USA.  And conditions today are not as good as yesterday!

UPDATE 2300z: The last spot of my 500mW 10m WSPR signal was at 2136z tonight. My last spot (of others) was at 215oz (KE5XV). Best spot of my 500mW signal was from CX2ABP at 11127km

10m Conditions - not quite as good?

Although a little early to be sure, the impression I'm getting is that 10m conditions are not as good as they were yesterday. It will be interesting to see how long the band opens transatlantic this afternoon/evening.  Running 500mW I will be missing some spots, but this is my impression so far today.

Typically, early afternoon WSPR transmissions here get 3-7 spots (reports)  per transmission despite running just 500mW out. Of these, about 75-85% are transatlantic reports.  Conditions today are actually NOT as good as yesterday either.

Received 10m 500mW WSPR reports today to 1444z

10m Antenna Effectiveness

Comparing my 10m signals with those of others, I suspect my antenna may be up to 10dB down on optimised systems, i.e my 2W is equivalent to 200mW from the better equipped stations. When better (stroke) I may try changing the 10m antenna for something better. A vertical 1/2 wave would be less directional on WSPR TX but might be noisier on RX.

Intriguing inter-G propagation on 10m

This morning I am copying G4SPE at 195km on 10m WSPR. This sort of inter-G distance is not uncommon on the 10m band. I assume this and similar spots are by normal tropo. Years ago the RSGB ran evening 10m contests and decent inter-G QSOs were possible with 10W SSB/CW to dipoles.  Every contest evening I would work down south or up to Yorkshire. I assume most inter-G WSPR spots are tropo but some may be back-scatter. I am sure consistent JT9-1 QSOs (and WSPR spots) would be possible inter-G if there was more activity. Something to try in the quiet years on 10m?

Early morning on 10m WSPR

As I left the 10m WSPR running overnight at 500mW I was able to see how soon the band opened for me this morning. As of 0900z just 3 spots received, all from RV3APM at 2428km in  Russia. No sign (yet) of 4X1 or LZ but it is very early and I am just running 500mW. On RX a station from Cameroon is coming through - TJ3TS .

UPDATE 1045z: EA8/DL9XJ  has spotted my 500mW twice so far.

Stateside on 10m again

My 10m 2W WSPR station is on now and getting plenty of stateside spots. A typical 2 mins TX burst gets 2-4 spots with most of these being from the USA and Canada. The earliest transatlantic spot (of me) was at 1118z, which is very early. These first class conditions cannot last, although I suspect next autumn will be good to the USA still.

UPDATE 1445z: I have now dropped my power to 500mW and am still getting plenty of USA WSPR spots with best DX 8756km to N6RY.  In 90 minutes there were 24 spots in the log when running 500mW out.

UPDATE 1725z: 41 spots of my 500mW 10m WSPR signal and most are transatlantic this afternoon. Plenty of reports still coming through. Suspect the band will be open transatlantic for hours yet.

UPDATE 1848z: 3 spots of my 1846z 10m 500mW transmission with best DX 6384km at a STRONG -8dB S/N.

UPDATE 1910z:  Still wide open to the USA with a report from  KI7CI at 8307km.   It could be a while yet before conditions drop out, or it might suddenly drop off.

UPDATE 1928z:  no less than 7 (yes 7) spots of my 500mW signal in a single transmission and ALL USA reports.

UPDATE 2014z: 3 spots with best DX 7660km. Band STILL wide open, even with 500mW. Even at 2020z still, getting stateside reports.

UPDATE 2040z:  10m still wide open but my last spot was at 2102z.

10m WSPR on RX - still wide open at 2042z
