500uW 10m WSPR (Wednesday)


Already, my QRPP  10m WSPR has been spotted multiple times (some very strongly) in the Canary Islands. It is quite possible that 500uW (0.5mW) 10m WSPR may reach the USA this afternoon.

UPDATE 1910z: 
 Amazing.  54 spots of me by EA8BFK (2880km). One spot of my 500uW (0.5mW) was an incredible -9dB S/N. This implies he would still have copied me with very low microwatts.

630m QRP WSPR overnight


10 stations spotted my 630m WSPR QRP overnight. Slightly better than previous periods, but no real DX.

630m QRP WSPR (Tuesday)

Once again I am on 630m WSPR with my 10mW ERP. So far, 3 stations have spotted me.

10m QRPP WSPR

Although the sunspot number is 50, according to my predictions yesterday, I have a chance of DX spots on 10m 500uW WSPR today. Time will tell.

UPDATE 1224z:  No spots.


UPDATE 1932z: 
26 spots of me today all from the Canary Is.. My theory seems correct. Some of these spots are very strong suggesting even lower power might well have worked. It is almost like a pipe between us.

630m QRP WSPR (Monday)

My 10mW ERP WSPR from the earth-electrode "antenna" in the ground was turned on about 1840z. After the first transmission, I was spotted by 3 stations.

VY0ERC 10m WSPR beacon

John's blog has a very good piece about this QRP 10m WSPR beacon high up in the Arctic. As John points out, this is a very high latitude and within the auroral zone, which can badly affect FT8 and WSPR signals.

John's blog is always interesting.

10m 500uW WSPR (April 1st)

My 500uW 10m WSPR is on, but no spots by 1410z. 

UPDATE 1707z:   Unexpected spots by EA8BFK (2880km). Conditions were good, but not exceptional. I was honestly expecting today to pass with no spots of my 500uW (0.5mW) 10m WSPR. I must see if there is a correlation between solar conditions and being spotted by DX stations on 10m WSPR with exceptionally low power.  My guess (unfounded) would be that this is possible only when conditions are exceptionally stable, although today rather puzzles me. Sadly, I am not great at Excel! I can use it basically, but can't do clever things with it.

UPDATE 1852z: EA8BFK (2880km) has spotted me again!

UPDATE  1900z: I have created a spreadsheet to see if I can discern any patterns.

UPDATE 1935z: 
This is the last week with 500uW (0.5mW) 10m WSPR.   Although this is just a few days, it suggests my best chances are when A and K are low.

Back to normal on 10m WSPR?

These last few days have resulted in some exceptional spots of my 500uW (0.5mW) 10m WSPR. Spots from the Canaries have been most days and I have been spotted in the USA by several stations in the last few days. Today, there are no spots at all, which I suspect is the norm. Perhaps I should try 10mW, which I suspect would be enough quite often.

UPDATE 2016z:   3 spots of my 500uW (0.5mW) by EA8BFK (2880km) today. I spoke too soon!

630m QRP WSPR (Sunday)

Rather earlier than usual, I have QSYed to 630m WSPR with my 10mW ERP. So far today (at 1455z) my QRP has been spotted by just one station G4FQI (128km).

UPDATE 2025z:  4 stations have spotted me.

630m QRP WSPR overnight


With just 8 stations spotting me, 630m appears to be going "off the boil". Best was Norway, so it does not look like poor conditions.

630m QRP WSPR (Saturday)

 For about the last 30 minutes, I have been on 630m WSPR with my 10mW ERP from the earth-electrode "antenna" in the ground. So far,  3 stations have spotted me.

10m QRPP WSPR

All week I have been trying out (again) on 500uW 10m WSPR. Yet again, my 500uW 10m WSPR has been spotted in the USA again and I have lost count of the  number of spots by EA8BFK (2880km) in the Canary Is..

500uW 10m WSPR (Friday)

Amazingly, EA8BFK (2880km) has spotted my extreme QRPP 6 times already!! I had to double check it really was 500uW (0.5mW). It definitely was!!


UPDATE 0917z:
  11 spots already of my 500uW (0.5mW) by EA8BFK.  Amazing.


UPDATE 1630z: 
 27 spots of me today including 3 from the USA. Quite incredible for 500uW. Conditions must have been very good these last few days. The map (from WSPR Rocks by Phil VK7JJ) shows the 10m WSPR spots these last few days with 500uW (0.5mW).

UPDATE 2122z:   
31 spots of my 500uW (0.5mW) today. I suspect conditions must have been exceptional.

630m QRP WSPR

My 630m 10mW ERP WSPR was turned on at about 1911z this evening. So far, 4 stations have spotted me.

UPDATE 2035z:  12 stations have spotted me so far.

10m QRPP WSPR (Thursday)

Once again I am on 10m WSPR with just 500uW (0.5mW) and I have already had 6 spots from EA8BFK (2880km) and one from Greece (a new country with ultra QRPP).

These last few days have been good. I must try to correlate this with solar conditions. I would expect to see some sort of relationship. I would not have thought these last few days were exceptional. Good, yes, but not exceptional.

A reminder that my beacon is pre-programmed to report the power is 500mW even though it is just 500uW (0.5mW) during these tests. 

I continue to be amazed.

It will be interesting trying ultra QRPP during the Es season.

UPDATE 1245z:  Already 18 spots today. EA8BFK (2880km) has spotted me as strongly as -16dB S/N  when I was running just 500uW suggesting 16dB weaker still might have been copied. 

UPDATE 1730z:  22 spots of me today at 500uW including a new reporter in the USA, who received me strongly. Amazing!!  


630m QRP WSPR overnight

 


My 10mW ERP WSPR has been on since about 2030z. 12 stations spotted me. No great DX.

10m QRPP again (Wednesday)

My 500uW WSPR has already been spotted in the Canary Is. by EA8BFK (2880km). I shall stick with 500uW (0.5mW) today, but yesterday was exceptional.

UPDATE 1116z:  EA8BFK (2880km) has spotted my 500uW (0.5mW) WSPR twice today already!

UPDATE 1707z: This afternoon, a station in the USA spotted me again when I was using just 500uW (0.5mW).

630m QRP WSPR overnight


A better overnight session with 18 stations spotting my 10mW ERP from the earth-electrode "antenna" in the ground.

630m QRP WSPR (Tuesday)

My 10mW ERP 630m WSPR is on. So far, 8 stations have spotted me. Yet again, the "antenna" is the earth-electrodes in the ground. At the moment the best DX is only EI.

10m 500uW WSPR beaconing

 As I was expecting today to be poor, I started beaconing at 500mW. Then I noticed that EA8FBK (2880km) was spotting me as strong as -2dB S/N, so I turned the beacon PA off at about 0945z and continued at just 500uW (0.5mW). At this tiny power he has spotted me twice by 1425z.

UPDATE 1920z:  EA8BFK has spotted me 21 times today when I was running just 500uW (0.5mW). It would seem EA8BFK is a single F2 hop, so he has the best chance. Please note that even though my WSPR beacon is pre-programmed to report 500mW as the power, it is actually 30dB lower (500uW) during these tests.
