Hi (agn)
See my earlier msg re Hateley CFA.
- Read in msg 146kHz = 136 kHz (somebody switched the keyboard caps here)
Should have done it earlier but a look on the internet with
"CFA" and "HATELY" as search element, I came across several documents.
Still a lot of 'really it works!' and a 'benefit of the doubt'
statements of those who can't accept that the system seems to be able
to generate such a fieldstrength by such a small radiating element.
In spite of the magnetic loop antenna and is widebanded also.
It appears that 279kHz in the UK will be occupied soon by a tx using the
CFA principle.
Further for those who want to experiment try :
http://www.antennex.com/preview/folder02/cfa_5.htm.
90 degs shift is there obtained by par en serie L/C network,
giving the opportunity to 'tweak' the system at it's best performance.
Figures given there are for 80mtrs.
Fact is, that when G8RW is using a CFA, he is doing a good job getting the sigs
from UK to me into 'deaf' untuned TS440.
(Btw when keyed "G8RW" on the internet a lot of hits were returned re his
VLF activity)
