Hello Stefan,

Mal was at least 10 to 15dB weaker than usual (daytime signal). Normally= he
is "head and shoulders" above the other UK stations and even mos= t PA's -
that are much closer - cannot compete, apart from PA0A.
PA0A was at his usual strength, so I assume my RX/antenna was OK.
I have no idea why G3KEV was rather weak today. Less power than usual or other antenna ?
I observed HE3OM and his audience for about 30 minutes and coundn't no= tice
any QSB (what is typical for combined surface wave / skywave propagation),=
so I assume all signals were surface wave.

Hi Rik,

I'm wondering. I've always thought Mal has a strong signal. Seems= to be
rather the usual power levels well below 1 W ERP. Anyway, at least he'= s
well visible on my grabber, sometimes 30 dB above noise in QRSS-3. I
seem to have a very sensitive grabber ;-)
