10mW ERP on 8m WSPR without a licence?

Today alone, I have had several reports on 10m WSPR that suggest 10mW ERP at ranges around 3000km would be copied.  

I am convinced following emails from OFCOM that, as long as ISM rules are carefully followed, a licence is NOT needed to run a beacon in the 40.66-40.70 MHz ISM band in the UK. This could well be true in other countries too. In the UK this means 10mW ERP.   It is my firm belief that such beacons, would be received at great range. It is a great pity more people are not trying this.

This is NOT the Amateur Radio Service. It is ISM.

10m FT8 RX on the cheap

This has definitely been on before, but as we approach sunspot maximum (and beyond) a timely reminder is in order. 

This works remarkably well and can be made very inexpensively, yet will bring in stations across the world most days. It may be built "dead bug" or, if you are really keen, as a simple PCB. As I have said before, it would make a great club project on a PCB.  The circuit is simple, so a single sided PCB should be straightforward. It means the "big rig" is free yet 10m FT8 may be monitored.

Bots? - NOT amateur radio

Already I have had more than 3 times the number of visits to this site than yesterday.  My posts are as boring as ever, so I think this must be bots probing.

Where I come from in South Devon - NOT amateur radio

This is where I lived as a young child. 

Funny how we just took it all for granted. 

It is now the most expensive resort in the UK.  Salcombe.

Cambridge Store - NOT amateur radio

Many overseas visitors are fascinated to see what is on sale in UK shops. This was the fruit section of a Cambridge shop last week.

10m 500mW WSPR TX (Wednesday)

Gear turned on about 0845z.  At 0905z, no spots.

UPDATE 2112z:  Today, 23 unique stations have spotted me. QRT shortly.

8m QRP FT8 (Wednesday)

My gear on 40.680 MHz FT8 (TX 1st, DF about 1950Hz) was turned on about 0845z. Unsurprisingly, no spots at 0856z.

UPDATE  1426z:  I am told by HC02 (1808km) that I appeared briefly in Southern Portugal but this did not appear on PSKreporter.  On RX the only spot is of 9A3TN (1481km).

UPDATE 1750z:  HC02 has spotted me again this evening. His report is now on PSKreporter. Also spotted (just!!) by SR4BBX (1217km) in Poland.

Plans for Wednesday

The impression I am getting is that Es is not as good as yesterday. My plans are 10m WSPR TX with the 500mW beacon and 8m FT8.

Sunspots - Wednesday May 31st 2023

Solar flux is 162 and the SSN 144. A=5 and K=1.

Clematis - NOT amateur radio

 

This picture shows clematis in flower in the garden at the moment. It is past its best now.
