This was posted earlier by N2OTO in Florida.  It shows the activity 40.66 - 40.70 MHz in the ISM band. I expect if we looked in Europe we w...

It surprises me that more use of some ISM bands is not utilised for beacons. In many countries around the world this is licence free with a ...

It seems many radio amateurs are becoming "appliance" operators rather than experimenters as was the case many years ago. This is ...

Shortly, I shall be turning on my 10mW ERP  8m WSPR under ISM rules on 40.680MHz USB dial.  This means my QRPP WSPR will be about 1450Hz hi...

It was very pleasing to see my short article about the use of the ISM bands for QRPP beaconing in the latest SPRAT.  In the UK this means 10...

At the moment my inclination is NOT to apply for a special permit to TX on 8m (costs £50 per year!) but to instead try 40.680MHz WSPR using...

Once again, I am trying my luck with low milliwatts WSPR on 13.5539MHz in the HiFer band using ISM restrictions. For the last 2 days I have ...

 Keeping to the ISM rules (very low milliwatts) I am on 13.5539MHz USB dial QRPP WSPR.  Any reports (local or DX) appreciated. UPDATED 1200z...

A reminder that re-reading the OFCOM pages I am convinced that operation in the ISM bands without a licence is legal in the UK (and probabl...

LoRa modules are available from Amazon and I expect quite a few other sources. To my knowledge, two people locally have experimented with 86...

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

A quick look at  https://www.tvcomm.co.uk/g7izu/radio-propagation-maps/europe-sporadic-e/  suggests that European Es could be promising late...

Following correspondence with OFCOM here in the UK, it is my view that anyone at all may use the 8m ISM band 40.66 - 40.70 MHz for beacons  ...

Certainly here in the UK and probably many (or all?) countries people seem to have licence free access to the 40.66-40.70 MHz ISM band as l...

 Some months ago, I had an email from OFCOM. The contents are shown here. It convinced me (although I am no legal expert) that beaconing in ...

Recently, I was asked this question. If it is, many more UK stations could get on 8m. It is my firm view that 10mW ERP is enough to get into...

This morning I am continuing my 10mW ERP 8m WSPR tests simulating ISM rules.  UPDATE 2050z:  G4WSZ (11km) has spotted my 8m WSPR 10mW ERP 8...

Another local ham is to do tests on the 8m ISM bands.  Once the weather gets better, he is doing some 10mW ERP tests (using his signal gener...

 OFCOM has still to come back to me about legal operation in the 8m ISM band and self certification if there is no intention to market a pro...

Although I am pretty sure that in the UK people can use the ISM bands for research without a licence, as long as they personally ensure conf...
