Please could you try your loop away from the tree. Preferably more than 2
metres. I have found severe bio-electric(?) noise from trees from 3.5 to
500MHz.using loops, whips and UHF Yagis. The noise drops to almost zero if
the tree ambient temperature is below about zero Celsius.

2. Most of the time there is a terrible broadband noise present in my
home location, which blocks everything below 14MHz and even degrades
Polskie Radio I on 225kHz and BBC4 198kHz (with the rx loop outside the
house in a tree). That's the reason why I did not report any reception on
500kHz in the last weeks. There simply wasn't anything to receive...
Although in a few kHz bandwidth this broadband noise of course does not
equal the fieldstrengh of a local broadcast station, the broader the
filter, the higher the level, unneccesary loading the mixer.
