The Ratnick TwoerMark 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...

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...

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...

Sbe Sb2-la Linear 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...
