Looks like a few stations testing in the back
garden at the moment Ed,
PA1SDB , posted this in the yahoo group, I like
the ref to '' interference from other 8 KHz testers
:-)'' be nice to have that problem
this side of the north sea !
Mini Whip looking to be the Ae of choice for
the moment ?
Stability , should be ok for +/- 250 mHz in
the 4 hour period , scaled from the 32 and
original 64 version

Positive copy here while testing localy.
07:23 8 PA1SDB Op4H -25 dB
02:48 8 PA1SDB Op4H -26
dB
*********** 03/05/2012 ***********
22:19 8 PA1SDB Op4H -12 dB

Now decreasing power to see where it
ends. The RX computer is connected to the PA0RDT Mini Whip, so i'ts getting
lightning QRN, play station noise, vacuümcleaner noise and interference from
other 8 KHz testers :-)
TX is a notebook, some wire and few 100 mWatt audio output at a
open pice of wire.

Hi Graham / second try
This one wasn't returned as
luncheon meat it didn't get there at all.
Second decode was -44dB, about
10dB / Noise in 46mHz. Signal level varied and about 20% data lost in a block,
XYL re arranged the configuration of the dining table antenna, they just don't
understand!

Tnx Ed,
Steady carrier, that should be one of the advantages of
Op on 8Khz , no real problems with sound card
's and frequency stability !
Look's like you may have some signals
from PA soon , not sure what's happened to all
the UK Tx stations , I know there was a
problem with having to inform the
met-office ..
