Mr. Joe Talbot,
Red Deer, Alberta,
CANADA
Dear Mr. Joe Talbot:
I have pleasure in verifying your reception of our test transmissions, on
the frequency of 7300 KHZ, 41 Metres, heard during the hours of 0230 to
0400
UTC, at your location.
The details mentioned correspond with the test transmissions being realized
by ZP20, Radio América.
I sincerely appreciate your comments. The "swooshing sounds" mentioned
come
from fine-adjustments being made in the system, and from demodulation
interference, originating with a nearby, high-power transmitter. The bells
come from the Compact Disc of Classical Music, utilized as test
programming.
The transmitter on 7300 KHZ is solid-state, and is capable of generating
2,4
KW of output power. It is a Class A Linear Amplifier. This transmitter is
located at our Villeta site. Owing to wild electrical supply, our
equipment
at Villeta functions from a group of accumulators, recharged by rectifiers.
The frequency of 7300 KHZ feeds a large Corner Reflector Antenna, having a
theoretical gain of 25 dBi. This antenna is oriented towards 184 degrees
from Magnetic North. Your reception most likely came from a trans-Polar,
South-North Pacific Ocean path.
I should mention that we are not yet at full power, but test at much less
than the 2,4 KW. Your reception was from a power of, approximately, 25
Watts!
The frequency 15185 KHZ is temporarily off-air, for equipment
reconstruction. We received no reports on this frequency, whatsoever.
At present, we are testing on 1610 KHZ (Medium Waves), using low power and
a
5/8-ths Wavelength Antenna. The tower is 125 Metres tall;
on 4830 KHZ, 60 Metres, also using a vertical tower; and on 7300 KHZ, with
the characteristics previously noted.
Your reception reports are always appreciated!
With best regards from Paraguay!
Maiteípa! (Greetings, in the Guaraní language)
