Ralph Steinberg K6CKX, 110 Argonne Ave. Long Beacht Calif. 90803 It's fun and exciting to experiment with facsimile. This mode of communication is gradually becoming as popular as slow-scan television and teletype. There are many potentials for which facsimile can be used in amateur radio. Before we discuss these potentials there are some facts and experiences your author had with facsimile which may be interesting. From April to the middle of September, Propect Facsimile Antarctic logged more...

Meter DSB

After oriie ten years of absence from the low f requeue ham hands in deference to the sun spot cycle and the lack of space for an antenna for other than six and two meters T heard rumors that ten meters was once more opening up. In a fit of wild spending i purchased a Lafayette HA-350 and started listening in on the low bands. Everybody seemed to be running gallons, lialf gallons and some poor slobs were only using quarter gallons. To me this was very surprising and just a bit painful to...

Signal Tracer

Winding No, of Turn Wire Size Most of the parts used should be easy to obtain, however, the RCA 40392 transistor, the toroid core and the TIP 14 transistors may be difficult to obtain locally. All are listed in the Newark Electronics Corporation Catalog No. 68. The 40392 costs 91 cents, the ITP 14 costs SL50 and the toroid core costs 1,20. The inch diameter toroid core is manufactured by the Indiana General Corporation and is made of Q-l material I built the transmitter except for the power...

But a similar explanation could be constructed for the two other configurations as indicated in table one. The model discussed is applicable only to ac signals and does not give any information about dc or steady state voltages or currents. he hybrid model is a very handy tool that was conceived to represent the bipolar transistor and provide a way of naming and describing the characteristics that the designer must know to build any particular piece of electronic hardware where transistors are...

Lafayette F 767 Headphones

Up to some space communications work hams are doing now, 1 especially liked the many excellent photos of old radio gear and workers, and on page 87 I noticed the Lakeshore Darts, Draughts, Chowder and Marching Society. Seems some Canadian hams had a problem of commuting to Montreal to make regular meetings. After discussions on 75 Meters they tried a meeting at a local tavern. About 50 hams attented the meeting and shortly decided on a highly informal approach. Wonderful idea, isn't it Somehow...
