Apologies if I have misunderstood your signature in any way.

No problem but Epsom is part of the black hole- first obstacle is a 12 storey block of flats 100m away and right in the way as the crow flies.

Worth monitoring output on FM just to see if you get a signal. UHF can be strange and wonderful stuff and you might just be lucky.

Monitored since your last post -nothing at all heard.

HF isn't line of site, so tower blocks aren't an issue.

I agree but S7 QRM is

S7 QRM is a choker agreed, great for listening to the 1kw boomers of the world, but S1 of static is preferable for normal listening.

with S7 noise, maybe opt for Digimodes? PSK31 can be quite amazing, even in bad conditions!

Bit of a bummer, although monitoring for twenty minutes or so might not be giving it much of a chance!

Sincere good luck whichever way you decide to go.

:think: Is it the entire Hf spectrum that is covered by s7 of noise? I only ask because sometimes it can depend on time of day/frequency .

I have been dealing with these problems for years as my location is quite frankly poor for radio. A 10 metre telescopic flagpole can quickly become a suitable compromise aerial covering several HF bands with the addition of a 4:1 or 9:1 unun ,some wire as a radiator and also counterpoise radials .
This could also be configured as an inverted L.

If some of the noise is generated from a definate source and you can pinpoint it's origin it might be worth your while calling the regulator and reporting interference to the amateur radio spectrum .

Don't lose heart operating with high rise buildings around you need not be an obstacle . I operate under these circumstances and I hold the DXCC/qrp certificate all acheived on phone SSB/AM and some FM on ten metres. I'm not certain how much garden you have available but I am certain that there must be a solution . It should be possible to operate radio from almost any location in my view.

You could use digital modes as suggested by Craig I hope that helps in some way
