Hi Roger, you will probably be able to pull that crystal some 150 Hz up,
which would get you inside the TA grabber slots.
BTW what azimuth is the orientation of your
loop?

That is an excellent
screen shot - most impressive! I generate the frequency by dividing a 3.560MHz
crystal by 26 and I am unable to measure the frequency very accurately. It
should be 137.6748kHz, but this could be off a
bit.

Next week I shall have a 3.582MHz crystal (30p
from GQRP club) which, when divided by 26, will place me around 137.769kHz which
is closer to the window looked in by the grabbers.
The beacon produces
2.4W (measured into 50 ohms) and the ERP from the fairly thin wire loop is
estimated as around 50uW. My WSPR beacon produces around 3dB
more.
