> EASY SATS, made possible for many operators to establish regular two

> antennas.... But those days are now over, and the present generation

> amateur satellite would be the way to go, but many experts say that
> although it could cover only one third of Planet

> Earth from its Clarke Belt orbital slot, so many amateurs will try to

> high cost to build a the geostationary satellites, and also the need
> to find a suitable launching vehicle that will also cost a fortune.

> So, what we are seeing now are small , low Earth orbit satellites that
> have created interest among a few radio amateurs, like Cuba's top

> Hector CO6CBF has built his own special antennas as well as azimuth and

> *Yes amigos, this is Radio Havana Cuba, and here are some recent
> schedule changes that took place on july 25th .... Starting on Friday
> July 25th UTC day, we are no longer using 9550 kiloHertz from 11 to 13
> hours UTC, and also NOT using 15340 kiloHertz from 13 to 15 hours
> UTC.... Then, here is now another important schedule change.... since
> Friday July 25th, our 11760 kiloHertz frequency continues to be on the
> air after 15 hours UTC and until 19 hours UTC broadcasting programs
> that we were previously only streaming to the Internet. The first
> three hours from 15 to 18 UTC are in Spanish, broadcasing our new CUBA
> ONLINE magazine show that received many nice reports from listeners
> picking it up via the streaming audio from www.radiohc.cu, and who
> suggested that we made it available also via short wave , something we
> have done using a 100 kiloWatts transmitter on 11760 kiloHertz with
> the 6 dB gain omnidirectional antenna that provides coverage to parts
> of North America, all of Central America and the Caribbean, as well as
> the northern areas of South America.  Reports received so far confirm
> what our engineering department had calculated to be the 80 percent of
> the time service pattern. So, give it a try, and tune in to 11760
> kiloHertz from Radio Havana Cuba from 15 to 18 hours UTC and then from
> 18 to 19 hours UTC in other Arabic and Portuguese....*

> Now here is item three of the middle of the week program of Dxers
> Unlimited...
>
> Over the weekend, several Perseid meteor shower advance fireballs were
> detected by observers, and this can best be described as signals of
> the beginning of the annual August Perseids meteors display. Normally
> the best time to watch would be during the shower's peak: August 11th
> through 13th. This year, however, the supermoon will cast an
> interfering glare across the nights of maximum activity, reducing
> visibility from 120 meteors per hour (the typical Perseid peak rate)
> to less than 30. Instead, late July-early August might be the best
> time to watch as Earth plunges deeper into the debris stream of comet
> Swift Tuttle, before the Moon becomes full. For radio amateur
> operators the yearly Perseids are among the best showers for meteor
> scatter propagation Dxing attempts.
>
> Now let me explain in detail ---- PERSEID METEOR SHOWER BEGINS as the
> Earth is entering a broad stream of debris from Comet Swift-Tuttle,
> source of the annual Perseid meteor shower. Although the peak of the
> shower is not expected until August, meteors are already flitting
> acrosss the night sky.
>
> By the way, TV Dxers in the days of analog television broadcasts were
> able to log many low band TV stations within the frequency range of 54
> to 88 megaHertz in the Americas using the ionized trails of meteors
> entering the upper atmosphere. You had to be pretty lucky so that the
> burn of the meteor will coincide with the time of a station ID... but
> dedicated TV Dxers proved that this happened more often than expected, as
> they kept cameras in front of the TV set's screens and also later kept
> videocassette machines running all the time during the meteor showers ...
> I began TV Dxing in the middle of the nineteen fifties, and was able to
> log the audio channel of the then on the air BBC One TV from London, when
> the super active solar cycle 19 sent the monthly sunspot counts to the
> above 200 mark, something never before again seen eversince....
>
> Digital Terrestrial Television broadcasts using any of the several
> available standards are not DX friendly at all, something that has
> taken its toll, reducing the number of TV Dxers dramatically in every
> country where the analog blackout takes place....

> Nevertheless there are still many nations around the world where the
> analog TV signals are still on the air and the analog blackout is not
> expected to take place until a few years from now.
>
> At the end of the show a short form solar activity and HF propagation
> update. Sunspot number hovering around 140, the solar flux was near
> 130, and the effective sunspot number was around 85 Tuesday at 15
> Hours UTC, add to this that  all the active sunspot regions show no
> signs of powerful magnetic activity. Best HF propagation conditions on
> the Northern Hemisphere to happen after local sunset and until one
> hour past sunrise.... So , here is Arnie Coro's advice for short wave
> listeners and radio amateurs alike if you want to pick up DX stations
> , stay awake after midnight and go to sleep one hour after your local
> sunrise !!!
