Sbe Sb2-la Linear Amplifier

Picture Inside Sbe Sb2 Amplifier

I he compact SBE SB2-LA linear amplifier operates at 1000 watts PEP input on 80 through 20 meters and 750 watts PEP on 15 meters. Although the SB2-LA was designed as a companion unit to the SBE 34 transceiver, it will boost the output of any SSB transceiver up to a full kW PEP. The input circuit of the SB2-LA uses a passive grid input circuit which offers a pure resistive load to the exciter. In the output a pi network provides matching to the transmission line with band switching from the...

Ave You Tried Air Mobile

By some strange coincidence, the number of licensed hams roughly equals the number of licensed private and civil pilots. A guess would also suggest that the number of active stations would also approximate number of active civilian aircraft 100, It also holds that there are a number of hamS who are actively interested in flying. What the percentage is, I don't know. At a recent luncheon of fifty hams at the Colt's Neck Inn,, six where active pilots, and at least two make it a regular practice...

Comdel Speech Processor Model

A prototype of the CSP 11 has proved itself an elective communication aid on the amateur bands over several years. Us prominent feature Is the Instantaneous limiting action without the harmonic distortion which often makes the use of conventional speech clippers marginal, particularly with SSB transmitters. Designed for relatively Insensitive high Z microphones a gain control Is provided the unit will enhance the intelligibility of voice signals considerably under difficult conditions, MIL...

Sb-34 Transceiver

Natural Stone Facade System

The SB-34 transceiver is a complete fout-band transceiver for 80, 40, 20 and 15 meters, with built-in power supplies for both 115 volts AC and 12 volts DC, The SB-34 is almost completely transistorized with 23 transistors and 20 diodes the only vacuum tubes used are in the final power amplifier and driver stages. In addition to the built-in power supplies, all the necessary inter-connecting cables are provided with each unit. Since a front panel mounted speaker is included, only a suitable...

Eico Vfo Stabilization

Vfo Oscillator Meteran

Although the modern sideband transceiver is a very complicated piece of equipment, it is not at all difficult to assemble the EICO 753 sideband transceiver kit. This transceiver has both PTT and VOX and the offset tuning allows you to move the receiver up to 10 kHz away from the transmit frequency. The engineering of this transceiver leaves little to be desired, and the step-by-step instructions are clear and easy to follow. At a time when so much amateur equipment is being bought factory...

Transceivers

The new Babcock B-550-SSB is claimed to be the world s most advanced transceiver utilizing techniques that significantly extend the state of the transceiver art. This completely self-contained unit uses the advantages of modular construction and provides high efficiency performance on SSB, CW and AM. With the exception of the 12BY7A driver and 4CX250B final amplifier, all the circuits in the B-500-SSB use transistors or integrated circuits, A total of thirteen integrated circuits are used in...

Transceiver CW Filter and Monitor

An inexpensive and simple transistorized accessory unit for improving the CW performance of any transceiver. Just about every transceiver on the market still lacks adequate bu lt-in provisions for CW work that is, a CW keying monitor and sharper IF or audio selectivity for CW, The author previously built0 a tube-type accessory unit that could be used with almost any transceiver to provide these functions. However, being an outboard unit it was not suited for use in mobile or portable...

SAN JOSE, CALIF, NORTHERN CALIFORNIA'S MOST COMPLETE HAM STORE The Tester can supply lots more power than is required to roast a good diode into complete uselessness, Fortunately, this is harder to do than you might think. The power dissipated in the device is the usual product of voltage times current, and since most transistors and diodes break down at under 20 volts, and can take over 100 milliwatts ,the average danger line lies around 5 mA. But some transistor may...

Ubcarrier Generator for Ham TV

Amateur television, or ATV, is beginning to become quite pupular. The availability of inexpensive vidicon cameras and the many articles appearing in ham magazines about TV have made it possible for the ham who wants something different, but not too difficult or expensive, to try ATV, However, one big problem of ATV'ers has been transmitting audio. One method is to use a completely separate transmitter and receiver system, as for example on two meters. This requires a lot of extra equipment arid...

The Ratnick Twoer Mark IV

A very simple two meter transmitter for loca contacts The Ratnick Twoer Mark IV is a simple two meter transmitter capable of a good signal with modulation percentage closely approaching 100 . As VHF transmitters go it is easy to duplicate. The circuit is straight forward and little trouble should be encountered as long as good VIIF construction techniques are used. All rf carrying leads should be as short as humanly possible. The rule for bypassing is as follows if you can't see the leads from...
