Hi Roger
Your new set up is working well! At least 8 to 10dB better then
before. You are now romping in at -20dB and loads of decodes
Top work. You'll be working A1AA next!!!
With best regards
Jim

I built a version of the
PA0RDT mini-whip just using an MPF102 and 2N3904 and it did a quite credible
job on 136 and 500kHz even using it in the shack. It would be even better out
in the clear away from the house noise sources.

Hi Horst, Jim, LF,
Same here, I have used a PA0RDT Mini-Whip active antenna for a good
while now & it's performance is very good right down to 10kHz, may even go
lower if I knew what to look for !!!
My online grabbers use the Mini-Whip antenna.

Hi Horst
I've just installed one of Roelof Bakker's (PA0RDT) active mini whips and it
is excellent at my QTH. Just my view, others may have different
experiences
With best regards

Subject: LF: Best receiving antenna wanted
Hello,
now that I am happy with my selectiv level meter Praecitronic MV-62 I am
looking for the best receicing antenna.
Especially I am interested in 400khz, 136kHz, 72kHz and below 22 kHz. With
my 40m longwire reception is not good enough and with a frame antenna of
900m copper wire it was disappointing, too..
I think, an active antenna for 0 to 500 MHz would be the best for me - but I
am looking forward to any other idea.
