The Ultra Cyber is a highly sensitive, stable rack/table mounted, research
grade, SETI CAPABLE, radio telescope, with many features.
One of the greatest points of the Ultra Cyber is; "No Operator Adjustable
Controls" Everything is done from your computer (486 and Pentiums).
The
operator may adjust Gain, Offset and Integration from the computer console
and, turning On/Off a calibrated noise source (noise source optional).
Included - a power supply ( US or European), 12 BIT A/D converter and
simple software (Basic), and NEW for 2001, Windows downloadable software
developed by Dr. John Bernard), from a special website.

As a leader in the amateur and professional research area, Radio Astronomy Supplies presents our newest system.
This radio telescope along with software will open up a new area for those in the private and professional
Radio Astronomy sector. This "turn-key" system is centered in the middle of the allocated radio astronomy
frequency bands of 406.7.
Both frequencies have been noted in the area of Pulsar detection and continuum radio astronomy!
Included with this System, Antenna Feed, LNA, Converter, Software and Instruction Manual.
(Coaxial cable additional cost.)
* Antenna: Gain : 15 dBi, Low side lobes (better than -14 dB down)
* LNA: 18 dB Gain @ .35 dB
* Frequency Converter: +65 dB conversion gain, @1.5 dB NF
* High input Intercept point and 3 pole filter front end
* IF Out: 70 MHz +/- 1 MHz
* Total System Gain: 100 dB
This "turn-key" system is for solar research. The VLF Receiver will display any solar ehancements reaching the D Layer
of the earths atmosphere. In addition, this is an excellent low cost sytstem for schools and individuals.
Very portable!
With this system, comes with the Antenna, Software and Computer Interface Cable, Power Supply and Instruction Manual.
40 KHz VLF RADIO TELESCOPE
Our new "VLF 40 KHz", Computer Controlled", radio telescope has been added to our product
line. As all of our systems, this is a high quality, low cost, research grade, radio telescope.
PRICE: $180.00
BANDPASS FILTER
1420 MHz 4-POLE HYDROGEN LINE INTERDIGITAL FILTER
This wonderfully engineered filter is being produced for us,
by Mr. Peter Riese, our European (Germany) engineering representative.
This filter will give the observer better selectivity, and will ward off
some types of annoying interference, such as radar. The filter will pass
the
1420 MHz signal and effectively attenuate unwanted signals.
The filter specs are as follows:
Filter Type: Interdigital,4 Pole,Chebycheff
Frequency (3 dB): 1405 - 1437 MHz
Insertion Loss: 1 dB Typical
Impeadance: 50 Ohms
Flatness: 0.5 dB
Connectors: SMA
Dimensions: 10.5 cm, 5.5 cm, 1.5 cm
1420 MHz CONVERTER
* Frequency Converter: +65 dB conversion gain, @1 dB NF
* IF Out: 70 MHz +/- 1 MHz
* Excellent Image Rejection
* N and BNC Connectors
* +12 Vdc Power
Your choice of Thermoelectric Standard Atmosphere, Thermoelectric with Nitrogen atmosphere
capability or Dry Ice (pending).
