Quite good results Joe
Very concentrated capture area this side ? main spots falling to south Uk
and Holland , quite low in the North West , nothing decoded this end ,
but at -17 to Roelof , you could of dropped 10 db may be another 6db
.. 1 or 2 watts and still shown up !
What are the dimensions of the Ae ?
Take another look tonight ,

Hi Graham, Roelof,
Thanks for the encouragement and reports. The dongle sounds very
interesting. Here still using old superhets!
There will be an encore tonight starting 2300.
Still tinkering on VLF and giving some thought to raising the aerials
again.
73 to all

Hello Graham,
Thank you for the accumulated results of last night's 477 VO1NA OP8
reception. Results are promising as propagation was rather mediocre.
I find it amazing how well the cheap RTL-SDR V3 dongle worked.
Is the signal to noise figure referenced to a bandwidth of 2500 Hz?
If so, using a 12 Hz filter for aural copy, yields an improvement of
about 23 dB.
73,
Roelof, pa0rdt
