Also included in this outdoor package for the loop installation are the mast mounting V-Bolts and Saddles and the short RG-6 F connector jumper to connect the loop to the preamp, and weather sealer. User supplied RG-6 coaxial cable is used for the long feedline that is run inside to the… 3. DXE-RFPRO1B-PI Power Inserter. This is the indoor unit that puts a well filtered and regulated 20 Vdc power onto the feedline for the preamp. It carries the loop RF to the receiver via the F connector. This unit also disables the power to the preamp when it is keyed by the transceiver amplifier keying line. The Power Inserter is run on 24 Vac from the… 4. DXE-PSW-24A-6AU AC Adapter. This clean power supply is a linear transformer that converts 120 Vac to the 24 Vac at 600 mA required by the Power Inserter. It is has the attached 2.1mm power connector. 5. DXE-RFPRO1B-IAP Indoor Accessory Pack contains the cables and adapter to connect the transceiver RF and keying lines to the Power Inserter. The F connector coaxial cable connects RF from the Inserter to the radio. A supplied F female to PL-259 adapter facilitates that connection, should you radio need it. An RCA phono patch cable is supplied for keying the Power Inserter and a RCA phono y-adapter provides the additional keying line connection for a power amplifier. 6. DXE-RF-30B Complete Component Package is for a system replacement where only an existing RF PRO 1B Loop is available.

Getting Started in EME
Bouncing signals off the moon has always been considered as one of the most difficult of the amateur radio disciplines. Traditionally, Moonbounce (as it's known) was practiced by amateurs who are the most accomplished engineers, as well as operators—but recent developments have now made it more accessible than ever before. "Getting Started in EME" sets out to explain what you need to know and how to get started in this captivating area of amateur radio operation. This 64-page paperback sets out the history of Moonbounce, gives information on the various EME bands, and the reasons for choosing them—and then explains the EME signal path. It covers the unique propagation effects, such as libration fading, Faraday rotation, and spatial offset. Ground gain, Doppler shift, and degradation are also covered. The book is practically based and focuses on EME at 144MHz (2m) and proposes, wherever possible, the use of equipment that is already owned in order to reduce the cost of getting started in EME. This is particularly the case with antennas, but you'll also find coverage of transceivers, pre-amplifiers and power amplifiers. Again, the emphasis is on the minimum possible requirement, utilizing equipment that may already be in the shack. There is coverage of computers/interfaces, software and operation requirements, and even your first EME contact! EME at 70cm is covered, and there are glimpses where the newcomer to EME might move onto when they find themselves bitten by the Moonbounce bug. If you've never tried EME transmissions or are just interested in what it takes to make that first contact via bouncing a signal off the moon, then "Getting Started in EME" is the ideal introduction.

HAMSAT
Since the launch of Sputnik back in 1957, radio amateurs have been listening to artificial satellites orbiting above the Earth. A mere four years after the launch of Sputnik, radio amateurs put their own satellite into orbit, thus beginning a series of amateur satellite launches that continues over 50 years later with the CubeSat operations of today. "HAMSAT: Amateur Radio Satellites Explained" offers details of what you need to know about amateur radio satellite operation. This 128-page paperback begins with the history of the OSCAR (Orbiting Satellite Carrying Amateur Radio) program, detailing the various incarnations from Oscar 1 in 1961 through to the present day. The book explains what's needed in an amateur radio ground station, from the antenna to the receiver. You'll find rotator information for tracking the satellite, designs for pre-amplifiers, and all manner of technical detail. There's a chapter dedicated to the ground station antennas, sharing the performance of many commercially available systems—and information on The Endless Dilemma of Polarization. You can read about Ground-Space-Ground Propagation, the Doppler Effect, Keplerian Elements; plus suitable transceivers, software, recent developments in this exciting field, and much more.
