SPRAT article

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 10mW ERP on the HiFer and 8m ISM bands under IR2030 interface regulations.  No callsign is mandated and this is licence free. It is a good idea to use a callsign that WSPRnet can cope with if using WSPR. Likewise if using FT8, choose a callsign that PSKreporter can handle.

Certainly on the 8m ISM band 10mW ERP WSPR is enough to reach into much of Europe on Es. The same is probably true of the HiFer band too.
