I built the original un it on a b readboard and it still is functioning well with its self contained battery su pply. In operation, I merely u nplug the frequency shift cable running into the transmitter and insere into the transistor AFSK and ad just th e frequency shift control on the T V to give the proper shift as ind icated on the tuning eye and scopt. Transistorized A FSK In the unit I used a 2N49:? tran sistor which is rather expensive, but a 2 N1671 Texas Instrument should work as well . The voltage used was 20 to 3Ovdc. Caution must be taken ill conjunction with the unijunction not to ground the emitter in operation, for this will d amage th e junction. .5V rms was developed on the aud io output which will d rive any audio circuit. T he unit may be used as ~ l C \V oscillator by breaking the battery supply and inserting a key. Joel Es.: hma nn K9MLD 2NIG 71 Or 2N 492 2N526 W6N RM T, U, (0, Al mo.!
