MICROWAVE UPDATE
27-30 September 2001
|
FRIDAY
AND SATURDAY, 28/29 SEPTEMBER:
DAYTIME
LECTURES AND EVENING FLEAMARKETS
|
After a fascinating first day at Update, we wondered
what could be better but these next two days lived up to the tradition
set by previous Updates ... excellent technical lectures during the day
and rewarding surplus "fleamarkets" in the evening.... and all this within
the confines of the hotel.
We can't cover all the lectures on these summary
pages but here are a few of the highlights. A wide range of topics was
covered from mobile microwaving in the Rockies to 24GHz moonbounce and
operations on the 76GHz band! In all these topics the obvious enthusiasm
of the speakers came through so well.
 |
Paul
Wade, W1GHZ, gave one of his well-known talks on the mysteries of microwave
antennas. Entitled 'The Secret Life of Antennas', Paul's lecture included
animated computer simulations showing feehorn radiation in the E and H
planes. Until you have seen these you just don't know what your little
old feedhorn is really doing for you! |
Barry,
VE4MA, gave a fascinating acount of the trials and tribulations leading
up to the world's first 24GHz two-way "moonbounce" contact just a few weeks
before this convention. Since his talk he has been heard in the UK, Germany
and Russia, working W5LUA on this band!
24GHz is really 'buzzing'
these days... |

Will,
W0EOM, told us how to convert surplus millimetre modules for use on 47GHz.
He knows a lot about this and has helped many US and other amateurs get
on these very high frequencies. |

Chip
Angle, N6CA, treated us to a most interesting talk on how to check dish
antenna performance using a laser pointer and then described the voyages
of W1LP/MM down the California coastline(see map above). To fill in his
spare time while at sea, Clint, W1LP/MM, is making a habit of breaking
N. American 10GHz DX records ... from ship to shore! All these big distances
are done with 1 watt of 10GHz to a 20dB horn antenna! Those Californian
sea ducts are certainly something! |

Bob
Johnson, KF6KVG, long-time friend and 76GHz partner for Will, W0EOM, described
his world record making equipment for that band. The availability of surplus
modules in the Silicon Valley area makes this a little easier for these
folk than the rest of us in Europe where the most direct route to the 75/76GHz
band would be the purchase of expensive German kits and mixer diodes.
Bob and Will are to be
congratulated on their recording brealing contacts. |
