Note that it says ideas. This gives your output tube datassheet less than ideal load, and the extra current required for oflF resonance operation does a nice job of heat- ing your output stage.

Unfortunately, there weren’t any- more spare beams in the garage, but a inch whip complete with mobile mount was found, and it was reasoned if it were installed above the 15 datassheet beam, which would be at 73 feet, a pretty fair country antenna for 10 meters would result. All items are brand new except vrdicons which we guarantee will work with the parts kit supplied when assembled according to the sche- matic and adjusted according to normal pro- cedure.

In this manner you can trace the pipe or water stream all the way across your property. Physically, they are the size of a quarter watt carbon resistor for the Varicap and a top hat rectifier look a-like for the Semicap.

Ob- viously while the watts is not to be taken lightly, it is obvious that when you get into the high gain antennas, squeezing out one more dB is a very much worth while thing. This, with a six volt battery; in the final assembly we found that we could just squeeze in datsaheet RCA VS 9- volt transistor battery or equiva- lent which raised the input power to 2m3643. Commercial equipment reviews will usually be rejected unless you are well known to us and have done writing for us before.

However, at this point it was decided that some pro- vision should be made for 10 meters. Well take a look at it and give you an estimate of the repairs needed.

At higher frequencies rf tends to tiavel on the surface of a conductor, the famihar skin effect. More and more big companies are using oin: The contact must have been con- tinuous and unbroken.

The receiver was being used only as a sensitive rf voltmeter with no caHbra- tion being necessary except for a datasheeet S-meter reading.

Nev- ertheless, when your man gets on the air, anybody interested will hear him announce your call as his manager.

Get your FCC commercial oper- ator’s license, and then work, at good pay, in your “hobby” field — radio and electronics. The basis for this article is the fact that some people liave the ability to locate un- dergrouiKl objects, pipes and water streams by so called witching methods.

Accordingly, it costs quite a bit of money to send envelopes to the many countries which have their own bureaus. With only milliwatts output, a good an- tenna is a must if you hope to work reason- able distances. Rated, net 30 days.

Now, for those of us who feel the above is a litde too much to tackle in one bite. I am assuming tliat you have located and marked with stakes aU of the buried pipes that cross your property.

I merely use this to illustrate a problem we have in ham radio. When light Is blocked relay closes. Or was it the night she’d met that hand- some man at one of her friend’s dinner par- ties? The soldering iron no longer beckoned. Consequently, all that is required in con- verting a TA Jr to a 15 meter monoband- er is first the removal of the traps and substitution of aluminum tubing of the ap- propriate lengths.

However, with the majority a leading question like ‘What is your oc- cupation? Datsheet snapped off the student’s lamp and walked into the kitchen dstasheet began to brew some cofFee. We are lucky to hear them working the midnight shift now-a-days.

dattasheet The interest is growing by leaps and bounds. But, assuming youVe datashset game, let’s push on with the task of shipping out.

It is the newcomers who cause the trouble. There is no set formula for getting a QSO going on an exchange of ideas, but we should try to toss out some tidbit to begin a stimulating exchange- Granted, there are some who are not interested in communicating and nothing you wiU say gain more than “By the dtasheet, what’s the rig on that end”.

But first and fore- most, the person making use of tliis abil- ity has to believe in it himself. While not suggesting a hitch in the Navy to obtain this endorsement, some other ways to get it is to sail on a passenger ship as an assistant radio ofiicer these fobs are assigned througli the unions or to enter the Radio Officers Union apprenticeship program.

Be certain to state the date on which your tenure commences, the date after which you will accept cards. You smile, perhaps a little 2n643, at the audac- ity of these statements.
