This particular track was plainly visible for a distance of about fifty feet. Then you have to go back to the reverse side and get the informa- tion. She thouglit, with a curl of her lip, how thorougiily right and fitting the term was.

Provision is made to bolt dahasheet two units together to form a single adtasheet, for those who find this more conven- ient. On the right of tlie JuUe are two Krohm-Hite oscillators for generating pre- cision ac voltages and wave- forms. The rig The basic aim hi this gambit is to ap- pear to do a slightly better job than the other feUow.

More recently, several manufacturers have announced units with voltage ratings in the to volt region.

The exchange of ideas is especially re- warding in a QSO with a station from an- other country. 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 meter beam, which would be at 73 feet, a pretty fair country antenna for 10 meters datasheett result.

These are popular priced units which afford the ham the full benefits of UTC’s established excellence for quality components coupled with dwtasheet reliability. So I have a habit of procrastinating my reply to the SWL cards until I have no other cards to handle. But the less exotic DX is usually not only willing, but eager to talk, not only about rigs and antennas, but about themselves and their families.

I have been successful in circumventing this waiting, knowing 2nn3643 many DXers are impatient for their cards.

Grid block keying of a pure CW carrier is employed with off set trans- mit frequency. Any ama- teur who submits proof of two way amateur radio communications with ten different countries is ehgible to become a full mem- ber of the DX Decade Club and will re- ceive this handsome award.

No detectable birdies from surplus oscillator products— you put the crystal in and you’re right where vou want to be.

A recent change was the addition of a double- pole toggle switch S, in Fig- 1. He’d dqtasheet up, one even- ing, looking at his watch, exclaiming, ‘Tve got a sked on ten in W2 land!

These cameras were rented out for temporary surveillance jobs on construction sites, county fairs, con- ventions, etc. One form is shown in Fig- 1, which someone developed quite a few years ago. Tune The Band for real versatility, 3 Gang tuning capacitor for performance.

When you have set up the arrangements with youj DX friend, and you are datashdet engaged as QSL manager, you can drop a postal card to the various publications which print DX information, including QST. All with no increase Hn price. You will probably find that the two points are separated by several feet.

Mass purchases, mass production, prod- uct specialization, and 15 years of antenna manufacturing experience. I got to know it well- Its’ whistles, its’ shrieks, its’ howls, and from time to time its’ effect on the neighbors, when ft inter- fered with television.

Element two consists of 20 multiple-choice questions on basic operating practice and procedures for radio- telephone most ships have voice ship-to- shore equipment. There is httle effect below Hertz. We can make the drop across Rl as small as passible by increasing the Q of the network. An exchange of ideas by speech, writing or signals.

The only grass in sight is the ground-up kind sprinkled onto pies in pizza parlors. Private QSL bureaus are op- erating but that expense is too great when at present one can send datashewt 14 cards to a foreign QSL bureau for 6 cents If the envelope is left open and marked “Printed Matter Only”. The correspondents asked questions, the answers to which are of value to any ham forced to use a miniaturized radiating sys- tem. The house was quiet. High level out-of-band signals are reiected ahead of the re- ceiver front end.

Plate dissipatton watts Filament power 6. Until— her sister came by one day and gasped this remark, ‘TTou aren’t sending that stuff to the dump? If youVe got something that needs fix- ing why not bundle it up and send it 2n3463 us for repairs? If you have been tuning external antenna couplers for mini- mum VSWR, you may on occassions have ended up, as I frequently have, with zero reflection but also with no output.

This pemiits the use of a mA field antenna relay which had superior isolation characteristics at MHz. These lengths of course included the traps. It also speeds up delivery of QSL cards to those who impatiently want them for certain awards. If your transmitter is cathode keyedthen here is your cure for that nippy key and the sparking contacts.

An auxiliary antenna tuner for loading the nnfni-mitter into a random length wire. We have in mind mechanical sweep mechanism, or saturated choke inductors such as are used in sweep signal generators or similar instru- ments calling for frequency modulation.

It is also possible to combine a sidetone keying monitor with a transistor to key the cathode circuit of a transmitter. Assorted tools for “on the spot” repairs and installation, What would you like included? 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.

Also connects tape recorder for both fN and OUT. With only milliwatts output, a good an- tenna is a must if you hope to work reason- able distances. A range selector peiTnits full- scale deflections of the meter for outputs of 15,and watts.
