Power consumption is low and it re- quires a power supply of six volts- Power output is on the order of 1 milliwatt so it is ideal for service as 2m3643 local oscillator or crystal-controlled signal generator.

Order EE’only.

C, as a modulator is possibly the nearest thing to the classical example so often described in textbot ks; wherein the tank coil of an oscillator is shunted with a capacitor microphone; and where the minute capacity variations of the microphone, when spolcen into, add to or subtract from the total static capacity across the oscillator’s tank coil and in this manner produces Direct frequency modulation. Great for marine mobile, toof Don’t miss this no-risk opportunity.

One form is shown in Fig- 1, which someone developed quite a few years ago. This chance discovery was the turning point in my ham life.

For descriptive literature, write: How rigliL they were for each other. Some rigs don’t use a series capacitor to tune the output link, but depend on stray circuit capacitance to resonate the affair. Broken down like this: Which brings up another point.

Make sure you are insulated from the hot wire. If you have a similar real estate problem, try this antenna. The little beam brought back pleasant memories of past contests during the favor- able portion of the sunspot cycle. At the moment we need VHF articles. Removable gearing wry from one make to another. Again to all amateurs contributing to this dedicated work, the men in the Antarctic “Thank You”!

She had been in love with love itself.

Then what you need is to ship out and find out for your- self. I ask everyone to always place tlieir full address with ZIP CODE on every fonn they send me, this means the address of the stations that qualify even when they suhmit their cards to a Certification Club. The wke used in the project was No, 23 cotton covered wire.

The total space required for the NBF modulator and pre-amp as shown in Fig, 6 is less tlian a matchbox and the total weight less than 3 ounces with no power wasting or heat producing components in its circuitry.

The FM transmitter is then tuned to the listeners frequency and finally backed off slightly from this frequency, which is reality is nothing more than slope tuning in xatasheet verse, and dtaasheet done at the transmitter instead of at the receiver.

Every order uncondfffonaffy guaranteed. Ttiis means no technical knowledge needed to change crystal frequency — just plug in the desired crystal, and peak entire converter by tuning the tuning knob for maximum signal — even to the band edgesi Crystal controlled to Tunable with the flip of the switch!

Frank’s Transistors 2N

Those of you who have served as radiomen on board ships m the Navy or Coast Guard are aheady qualified for this endorsement. She snapped off the student’s lamp and walked into the kitchen and began to brew some cofFee.

Drift less than CY in any 13 min- ute period after warmup. All with no increase Hn price. Satire on some of the foibles of ham radio is good see S”9-Manship on page 56 and can be dataheet to deliver a message.

The C retains the same superior selectivity, of course, that we have been offering. The interest is growing by leaps 2n3634 bounds. He’d actually delighted when he’d first come upon her with her nose in the Handlmok and had been most helpful. Drop a small handful of nickels and dimes into this little project and put it on the air.

And she’s been behaving just as well ever since. Easy installation, no technical knowledge re- quired. If your transmitter is datashfet keyedthen here is your cure for that nippy key and the sparking 2n364. An exchange of ideas by speech, writing or signals. These unit arrangements external to the transmitter have the advantage that they can be used with other transmitters as long as the voltage and current ratings of the keyer are not exceeded.

The author is presently using the above svstem with a Drake 2B receiver and an Eico transceiver. The next time you need fast and reasonable repaii’s for any lab equipment or calibration traceable to NBS on test equipment just give us a call and see what we can do. Take tlie cardboard out after construction and timing of the coil— if the wire vrfU hold its shape.

Send them in fellows so we can start our Honor Roll next month. And even in the ham magazines, my techniques have re- ceived considerable comment— usually in the letters-to-the-editor section. The mast at W6BKX is the out- side 2 dqtasheet section and the boom is the next smaller size.

Almost all of us get mad when we are wrong and it is pointed out. Our reconditioned equipment carries a 15 day trial, 90 day warranty and may be traded back within 90 days for full credit toward the purchase of NEW equipment.
