Hello Mike,

Good to hear from you and thanks for the report.

You're quite right and QRM is a real killer especially on the lower frequency bands.
This Christmas break I was plagued with QRM even up to 20m from neighbour's festive lighting.

I'll be retiring from work soon so will have to get QRV on LF digi modes as that seems the way to go.

Chris.

You are 599 here of course.

As for activity, I think CW is much harder now because the noise
floor in Europe from DCF and HGA is much greater than ten years ago.
Plus local TVs, wall-warts etc, create much QRM to 'wideband' modes
like CW. I used to work DL quite easily using much less power than I
run now, but have recently failed to be heard by several DLs calling
CQ.

However there is still a lot of activity on narrower modes. One of my
transmissions on Opera32 last night resulted in 10 reports, 5 of
which were greater than 1000km away and a couple more than 2000km
away. A few nights ago I received Op32 reports from 18 stations in 9
countries, including Russia. Just think how long it would have taken
to work them all on QRSS3 or 10.
