Hi, Dave, LF.

You're a good signal here - about 589, by ear. Antenna is a 20m "Tee" at 5m,
tuned by the ubiquitious plastic bucket variometer, 500 kHz preselector into
an ICOM IC-PCR1000.

Subject: Re: LF: 500 kHz loop antenna ?


The TX is now finished, apart from sorting out a netting method.
First time I connected it to the antenna I found the SWR was
infinite! Yesterday I lashed up a simple impedance meter (effectively
a noise bridge with the 'noise' from my sig genny. That showed me
that it had a beautiful resonance on 160m, where it worked before I
added the extra loading coil. I have just reconfigured the
connections to the loading so about to check it again and hopefully
resonate it on the right frequency. All part of our experimentation!

You used to be able to see my 136kHz loop on Google Earth but they
have just updated their mapping and it is no longer there (which is
right!!)
