Canadian Amateurs to Lose 220-222 MHz
Barring an outpouring of "compelling arguments to the contrary," Industry Canada will reallocate the
220-222 MHz portion of 220-225 MHz from the Canadian amateur service to the mobile and fixed
services. Under the provisional reallocation, which will take effect January 25, the amateur service
will be allocated the 219-220 MHz subband on a secondary basis. Additionally, the amateur service
may be permitted use of 220-222 MHz "in exceptional circumstances on a secondary basis to assist
in disaster relief efforts."
SATELLITE ATV REPEATER
From: "Robert Bruninga" <bruninga @ usna.edu>
Reply-To: Discussion of Amateur Television of North America <atna @ mailman.qth.net>
I'd like to form a core design group to design a satellite Amateur TV repeater. Everyone knows this won’t
work unless the satellite has lots of power (far beyond our usual power budgets). But what if there was a
launch opportunity that had 100 watts or more power available? I'm in the middle of a lunch campaign
and don’t have time right now to work up a link budget,but thought some others might enjoy looking at the
problem.
1) Assume ranges of 1500 km
2) Assume 100 watts DC average power
3) Uplink FM on 1.2 GHz band
4) Downlink VSB FSTV on 70 cm band
Someone want to work it up? Goal would be anyone with a cable ready TV to see signals using maybe
the gain of a handhled Arrow antenna for downlink?

I have updated and put on our web site application notes page an Inband 70cm and crossband 70cm/23cm
ATV repeater example block diagram, component sources, prices and info. You have plenty of time to print it
out or bring it up on the computer over the winter to think about putting one up in your area come the spring
thaw.

ATV DX Records
I have started an ATV DX Record web site: http://www.hamtv.com/atvdxrecord.html. I often get asked the
question of how far ATV can go or what the record is. Rather than point them to check past issues of
ATVQ and Bob, KA9UVY's Midwest ATV DX Report and other articles and magazines, I thought it would
be good to have it all on one web page with all the pertinent information. There are just a few to start
right now and I hope the word will get out and I hear from those who have beaten the listings or have ones
to add. The categories for now will be by ham band, overland, over water, rocket and balloon, AM or FM
analog standard scan ATV. There is also a link to a USDS web site that has a good over the earth distance
calculator if you enter the latitudes and longitudes of the two stations. Best DX in the New Year,
