SEC: UNCLASSIFIED - RE: Radio Antenna Tower Demolition Today (fwd)



Bob, 

This brings tears to my eyes.

I'm sorry to hear this.

Canberra's Belconnen Transmitting Station (Royal Australian Navy) has its
44kHz Tx towers still intact, but the antennas have gone. Each ~600ft. The
towers will also come down some time in the next few years.

The Tx was 250kW at its best. In latter years it was only being asked for
~30-50kW. Urban encroachment caused the lower power quite some years ago.
People in a 5km radius were complaining that their washing lines were giving
them zapps, and traffic lights in a similar radius were behaving strangely
during high power transmissions...

Best wishes,


Peter Ellis VK1KEP
LCDR, RAN
Canberra 
that happens to be the biggest urban area 
in the Australian Capital Territory (VK1)

Today (fwd)

		Not SIG/BBS related, but... its going to be a sad sight...

		The final demolition of the Radio Antenna Towers [in
Annapolis Md] is
		planned for approximately 1530 EST today, Thursday, 9 Dec
99....
		... a superb view of the simultaneous drop of one 1200'
tower
		and six 600' towers.  The 300' tower at the end of the golf
course
		driving range will drop moments before the seven taller
towers. 
		Please be prepared for a very loud boom.

		They will initiate over 150 simultaneous charges...!  CNN
should cover it.

		These were the VLF arrays for comms with Nuclear
		Subs.  Resonant frequency was 38 KHz... and other VLF...
