Hi all

Where does the distance for capaciive and or magnetic coupling end and the main mode of electromagnetic radiation coupling begin? Is it defined?

Sent via my own personal Too-Way (two way) Earth Station to and from the Eutelsat Ka-band satellite  http://www.tooway.co.uk/  at approximately 172 degrees Azimuth in the Clarke belt owing to BTs 19th century cable technology inability to provide a good enough 21st century broadband service. I agree for this message to be passed on to BT Plc at 81 Newgate Street, London EC1A 7AJ  via the snoops at GCHQ Cheltenham, thanks for your cooperation it is appreciated.

 Hello Andy.
  
 Not about the first claimed 73kHz QSO, but just for
 info
 :
  
 the first time I heard Peter G3LDO on 73.4 kHz normal
 CW (
 338 km ) was around november / december 1996. Later, I had
 my first xband QSO
 73.3 / 3.570 kHz with him 28 march 1998. I received his nice
 QSL for this event.
 It was, I think, the only all time QSO normal CW xband from
 UK to outside UK.
 But Peter and probably others UK stations had also some
 “DX” QRSS QSO xband 73 /
 137 : one day ( I do not remember the date ) I see Peter in
 QSO QRSS3 with
 HB9ASB...

 Can anyone remember what the first claimed
 73kHz QSO  was
 .  I seem to remember it was a few tens of metres across a
 car park,
 probably in 1996

 (Strictly, that was a capacitor not radiation,
 but...)
  
 I'm giving a talk on LF/MF in a couple of weeks,
 and want to get the
 timeline right.
