10m WSPR analysis by Bert PA1B

Bert has kindly analysed 10m WSPR spots of my 500mW beacon as received by K9AN on several days in the last few days. Clearly mid-afternoon (1400-1500z) has been his best time with most spots.

A day NOT on 10m

Today, we went on the train to see our younger son and family who live near Canterbury. The train  ride is about 2.25 hours each way and we get about 5 hours in Canterbury, which in my current condition, is just long enough.

As I was out most of the day, I was NOT active on 10m during the day as usual.  Sunspot number was 122 today (going up) but 10m conditions were only "fair".

Since about 2000z I have been on 472kHz WSPR and spots have been exchanged with the usual suspects!

472kHz WSPR

The best DX reception here on 472kHz last night (using the earth-electrode "antenna") was LA4ANA (1042km). The most recent 472kHz spots with 5mW ERP from the earth-electrodes are shown below.

10m USA WSPR spots today

The 10m USA openings in the afternoon are definitely getting shorter.

First USA station to spot me on 10m WSPR was K9AN (6505km) at 1426z. He was also the last station in the USA to spot me at 1632z.

This morning, we were at our neighbours for coffee and this afternoon with other friends in the close for drinks and mince pies.  Both were nice occasions. Not being able to speak easily as a result of my brain bleed is a real handicap. I do hope this recovers during 2015.

Still no USA spots on 10m WSPR

It is now 1345z and, as yet, no-one in the USA has spotted my 500mW 10m WSPR beacon.  A range of Europeans copying me. It may be just too early for the USA at this time of the 10m.

Sunspots and 10m

Sunspot number today is 113 and 10m propagation is expected to be "fair". Having only just turned on the 10m 500mW WSPR beacon, I have still to find out for myself.

472kHz again

In the end I gave up on 6m and returned to MF (472kHz) shortly before tea. G8HUH (250km) and PA0O (440km)  have both spotted my 5mW ERP already.

Unique 472kHz spots of my 5mW ERP from earth-electrodes today.

First and last 10m USA WSPR spots today

The first spot of my 10m 500mW WSPR beacon was W3CSW (5886km) at 1320z.  The last 10m WSPR spot of my 500mW beacon was K9AN (6505km) at 1624z.  The openings are getting shorter.

The evenings are getting slightly lighter now: I was in the garden trimming branches today until nearly 1630z. Official sunset (when the sun actually goes down) is before 1600z, but afternoons are a little longer now. Next week the mornings get better too. Roll on spring!

6m - another 1 hour then QSY?

I'll give 6m WSPR another hour, then I'll probably go back to 630m (472kHz) where there seems to be activity. 6m really is (almost) a total wasteland at this time of year.10m is good.

6m activity

In the summer Es season there is usually no shortage of 6m WSPR activity, but once the main Es season has gone, activity takes a nosedive. This is a pity as it is outside of the Es season when WSPR is so useful. In the main Es months I can work all over Europe, North Africa and occasionally further with a few watts of SSB and a vertical omni on 6m. I regularly spot, and get spotted, on 6m WSPR out to 200km+ in the Es season with QRP WSPR by tropo and by aircraft reflections.   The better equipped stations can probably work real DX by scatter at most times of the year.

Please, can we have a few more on 6m WSPR at the quieter times of the year?
