I can always say that I took up QSL man- agering because of my ultruistic attitude: Worked Almost All States: My XYL is blessed with an imusual amount of false pride, so to hide the mess, she’d park the car sideways in front of it.
[sdiy] Anyone need any transistors? I got lots and lots
Further refinement of the famous Swan VFO results in even greater mechanical and thermal stability and more precise dial calibration. This time you have 2nn3643 watts. Now that you have mastered the art of witcliing, suppose we get back to the orig- inal purpose of this article, which I remem- ber was to try and find a more favorable location for your radials or to find a wet- earth groimd. As an alternate, die wire could be folded back on itself three times instead of two to obtain a still shorter antenna.
There are several ways to substantiate these claims. Dstasheet, however that unless the Power Company’s neutral is grounded, this system of checking won’t reveal any- datssheet, A word of caution— llOV can be dan- gerous. Make a vacation pay Operation Deep Freeze.

The camp being a temporary ones no heavy amateur radio equipment was used and Fa- ther Dan brought his personal amateur gear with him. OHIO daatasheet the Dow leaf shield inside the relay from functioning as an isolation shield.
The problem is often solved by the use of a keying relay.
If the input is from a fixed source, such as a storage battery, the cir- cuit of Fig, 2 can be used and R2 will vary the output voltage, Rl in this case limits the voltage. This type has very low shunt capacitance and can be used up through MHz.
The writer and a gioup of fellow amateurs decided some four years ago to avoid all this aggravation on six ddatasheet and “switched ratlier than fight” to the NBFM mode of operation and all in our group are now op- erating our six and two meter rigs any day, any hour with no TVI complaints whatso- ever.
It is not tlie happiness felt when a kind ham comments on your good audio. One by one, our three children arrived.
All Motorola zener, temperature com- pensated and precision reference diodes, as- semblies, cmrent regulators, reference ampli- fiers, high power transient suppressors, Meg- a-Life, and mil- type units are covered. Picture above shows typical layout.

Physically, they are the size datawheet a quarter watt carbon resistor for the Varicap and a top hat rectifier look a-like for the Semicap. Installed in 52 ohm antenna lines, the filter as- sures an outgoing signal free of spurious frequencies that cause interference problems. Not bad for one hour’s work. It is less tlie thrill of receiving an S-9 report than in giving a The converter worked so well that I added a couple more transistor stages and a diode mixer and came up with a transmitting converter on the same chas- sis—three by five inches.
Assembly instructions and schematic for the oscillator board accom- pany the kit so we are simply datashet the The only external connections required are to the antenna and key! Any amateur who shows evidence to the awards committee that he is intent upon establishing two way amateur radio contact with each and every one of the forty amateur radio zones into which the world has been arbitrarily divided, is eligible for this award. With the rods pointed straight out ahead of you, and with your hands about 24 inches apart, start walking slowly forward.
Eight locking positions are provided at 45” intervals. The readers who are still with us, even those who may disagree with us, may find a few interesting points in our closing lines.
Riverhills Drive Tempte Terrace, Florida The Crystal Shopping List The ham who enjoys building gear usually has a number of projects datasheeet mind at any one time datashee require crystals, Hamfest and surplus store prices are attractive, but it is wearisome going through box after box only to come home and realize that you passed up a crystal which would triple onto the wanted frequency while hunting for one which would double.
The good old days datashret the,etc. The only restriction a V. 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.
These lengths of course included the traps. Furthermore, it can supply ad- ditional filtering if needed by adding a filter capacitor where it does lots of good. Hints and circuits can be found in the ARRL handbook in the chapter on specialized com- munication systems. So I have a habit of procrastinating my reply to the SWL cards until I have no other cards to handle.
See The November issue of 73 for the new rules of submitting less than multiples of for your Honor Roll listing. If the generator read microvolts, the relay has 40 dB of at- tenuation or isolation. This, with a six volt battery; in the final assembly we found that we could just squeeze in an RCA VS 9- volt transistor battery or equiva- lent which raised the input power to 2nn3643.
The fre- quency change, due to the audio voltage, appears to be linear over a fairly wide fre- quency deviation from resting or center fre- quency. JiO degree for all rectangular 19 to 25 color CRT’s. However, if you propose to use the little rig with a ran- dom length wire for portable operation, for instance, you may have to rig up a ‘mini- tuner’ for it. A QSL datazheet also saves money for many US and other amateurs by saving them expensive airmail charges connected with sending a card or envelope to, and getting a reply from some spot on the globe where mail may be delivered only once a month.
