Hi Mal and LF,
Well, all I can say is that here the signal to noise ratio on RX is =
better on my PA0RDT than it is on my long wire (inverted 'L'). I have =
always thought this a bit strange, quite often weak signals that cannot =
be seen on the wire are perfectly copied on the PA0RDT. This applies =
from 136kHz to 3.8MHz. I cannot see what else it can be other than local =
noise/QRM level. 80m is another prime example where the noise has =
gradually got worse over the years here.
Vy 73,
Chris, G4AYT, Whitstable, Kent.
