We were on all night and I had to go out this morning to see my mum in the nursing home back on now

we have been on 6305khz without any trouble from ofcom for a few years now you were right thats why we try to stay on 6305khz .We have been told that ofcom are no longer bothered with radio merlin unless we course interference.We use to use 150 watt but had major problems locally hence the low power

With efficient antenna a reduction from 150 watt to 20 watt only leads to a 9db fall in signal strength so if Radio Merlin registers a signal strength of S9+10db with 150 watt, it's strength will still be S9+1db with just 20 watt... but with much less chance of neighbour interference... so propagation conditions are much more of a factor in a strong signal than transmitter power.  The big stations have to make a lot of effort and power to get signal strengths of S9+40db using massive antenna networks and 100kw or more.

The high power Dutch pirates must generally live areas not close to neighbours.... eventually with high RF power it is inevitable to cause QRM in the surrounding area.

I agree with what you say.

Low power works well with an efficient aerial when the propagation conditions are favorable where the broadcast emanates from.
