Lots of WSPR activity on Top Band tonight. I thought I'd take a listen and so far have decoded 10 different stations from Norway to France.
I don't have an antenna for 160m so I'm using my multiband dipole that covers 80m, 40m, 20m, 10m and 6m. However the best SWR the K3 ATU can manage to get with this antenna is 10:1 so I daren't transmit. Most people seem to be running 10W which is a lot more than is normally used for WSPR on other bands.
I think 160m is an impossible band to operate when you only have a very small attic to put your antennas. But it is interesting to see what I can receive. Some of the stations I have received are coming in at good strength. The accursed local QRN is on sounding like car ignition interference spikes but the K3 noise blanker took it right out.
