Mail Order Through Distributors

By the way, if you are selling through distributors, you should know that 73 is the ONLY ham magazine read at home by most of them. Over 800 distributors get 73 at home and look through it to see what products they handle are being supported by a national advertising campaign.

Amateur Microwave Antenna 2100-2600mhz Down Converter

Amsat 13cm

The most common commercial unit ihat has been used successfully is the Drake 2880. Hundreds, if not thousands of these devices have been plucked from the shelves of surplus distributors here and in Japan. With a relatively simple modification, 2400 MHz can be converted to 144 MHz by simply changing the main oscillator crystal. The 2880 then becomes a great asset for terrestrial and S-band hamsat reception. Other changes to move the IF (Intermediate Frequency) filter center down to the two-meter ham band, and tune the input filter with very slight lengthening of three internal striplines to favor 2400 MHz, provide useful gain and noise figure enhancements.

Editorial By Wayne Green

While I may be patting 73 on the back more than it deserves, I do note that a little over a year ago there were only a couple of FM rigs available and today there are over a dozen and the big problem is back orders. Distributors are raising cain trying to keep units in stock. This is Fine for the amateur equipment industry (and they needed something ikedhis pretty desperately), but the main bcncfactor is amateur radio itself. . . with thousands of stations coming on FM and having a ball.

Cushcraft Ringo Ranger

Cushcraft has announced a series of Ringo antennas which have three half waves in phase by virtue of an eighth wave phasing stub. There are models for the 146, 220 and 450 MHz bands. This new antenna has both added gain over a regular Ringo antenna plus greater concentration of the signal on the horizon, where you normally desire it. Ringo owners may prefer to get a conversion kit to extend their present antennas. These, too, are avail able from Cushcraft distributors. Cushcraft clams to sell more ham antennas than all other antenna manufacturers combined - and this seems like a reasonable claim,

Action In Docket Case

he Commission said that the purpose of the new rules is to require compliance with equipment standards by manufacturers, importers, and distributors of rf devices, as well as by users, and that the rules apply to many persons and companies not now directly subject to regulation.

Why Abuse Semiconductors

American readers, J iie ratings of American semiconductors may or may not be optimistic. Commercial items will certainly be as good or better than the catalogue says, but you cannot trust surplus or bargain items at all. In regard to the latter you will find that a diode rated at, say, 400 PIY, may actually be anything from 0 PIV to 1000 PIV when you measure it. If you depend on it being the theoretical value, you may be in strife when you go to use it. This situation tends to be worse for the better bargains , but 1 hasten to add that there are several reasonably reliable distributors of inexpensive semiconductors, But you never want to make the mistake of taking their word for any ratings.

He Ueneral Radio Experimenter

There has just been added to the General Radio Co. line of apparatus a test oscillator for aligning' and adjusting receivers. While this instrument has general application, it is particularly suited for servicing the Radiola 60, and was designed with the service requirements of this receiver in mind. The Type 320 test oscillator should therefore be of particular interest to distributors and service stations handling this and similar receivers.

These tasks would he relatively simple if all the components in a network came from the same vendor. However, it is indeed rare that all links in a network such as modems, modem cables, multiplexers, pads, LAN connectors, LAN cards. LAN cahle types, hubs, bridges, servers, gateways, and PBXs come from the same vendor. There are also different persona computers, workstations, minicomputers, and mainframes.

POWER During my recent visit to Los Angeles I talked with K6RAD, Tom Litty, through the PARC repeater and then met him later at a PARC club meeting, Tom, the president of C, T. Power, invited me to stop by and see Iiis operation in Hawthorne where they are making the 2m power amplifiers for FM which Henry Radio is selling under the Tempo brand name. Bright and early the next morning (well, fairly early) I headed for Hawthorne and was talked in by Tom through the repeater and then direct on 76, The two meter power amplifiers were impressive enough, with models running up to 100W output The real mind-boggier was a tiny 220 MHz transceiver which they had hi prototype and which they planned on being able to sell through the distributors for under 180. With a rig like that available, it should be no time at all before we start seeing 220 repeaters springing up all around the country. This makes 220 inexpensive and practical.

External Radio Power Amplifier Typeacceptance Requirements

The effectiveness of type acceptance in halting promotion of amplifiers for illegal applications indicates that it should be maintained, the Commission said then. Numerous manufacturers and distributors of amplia f iers designed or promoted for Illegal operation have ceased manufacture or marketing since type acceptance was imposed.

How Good Are Vanguard

Our devotion to amateur radio rather than high profits is the reason. Of course some profit is necessary, and this we accomplish by putting our 12 years of experience towards efficient manufacturing. Printed circuits, semi-automated assembly, and dip soldering are a few examples of cost-cutting techniques. Eliminating a case and switch (which you can easily supply yourself, if needed) helps keep the cost to a minimum, Aiso since we have no dealers or distributors, you save the 30 to 40 markup which would otherwise be necessary.

Is 73 really dropping circulation, as ARRL recently reported in HR Reports The fact is that 73's growth this year has been without precedent . . . and both HR and QST know it. They are hearing this from readers, authors, dealers (who tell them that 73 is outselling their magazines in the radio stores), from newsstand wholesalers (who say the same thing) and, worst ot all, from the advertisers.

Design Considerations

One of he primary considerations in designing the remote swap mechanism for the HP-UX 6.0 system was to maintain as much of the current interface as possible. We wanted the swap device table to continue to specify the swap discs, and the use and availability of swap space to be represented by a swap map. Efficiency was important, so we had to consider methods to minimize the number of requests for swap space made from a client cnode. If the swap maps were maintained only on the server all requests for swap space would be a remote request, whereas if each cnode maintained its own swap map it would only need to make a remote request when its local swap map indicated that it was out of swap space. For these reasons two new-concepts were introduced the global swap space and the local swap space, The global swap space represents the total amount of swap space that is allocated to all clients and exists on the root server. The local swap space is the portion that is allocated to a...

An eveJ i greater improvement can be obtained with a 6AJ5. This tube is not well known and is expensive ( 4 wholesale) when bought new. It was designed primarily for operation with 28 volts on the plate and screen in aircraft radar equipment, but with norm a I voltages it has a higher t ra i i scon duct an ce and draws more current than the 6AK5 and hence has an even lower noise figure. If you run into any surplus equipment using this lit lie bottle, cannibalize it of these little gems. The procedure is the same as with the 6AK5, though undoubtedly better performance would be possible by juggling the parameters slightly.

Jk Flipflop

For x*easons unknown to me, some of the major suppliers do not seem to handle Fair-child semiconductors. However, other distributors do- The quoted small-quantity prices are 3.95 each for the Flip-Flop and 1.65 each for the gates. To order, specify Fairchild JH F1 ip-Flop, type UX8992328X. 1 he gate is the Dual 2-input gate, type UX8991428X. A letter to Fairchikl Semiconductor, 313 Fairchild Drive, Mountain View, California will get you a list of distributors who stock the G's.

Ouinr Enterprises

Devices are listed numerically within specific categories enumerated in the table of contents. All are available from your Fair-child Distributors. The catalog contains a list of all the distributors who have these items on the shelf for immediate sale. It contains a numerical index as well as a break-down of the various devices.

Ng Observatour

Fairchild Semiconductor View 1970s

The Observatour has certainly proved to be a wonderful means of keeping manufacturers and their export distributors better acquainted and more aware of each other's problems. General Radio has always been pleased to have representatives of its export distributors or any of their customers visit Cambridge at any time to obtain first-hand information. And of course such an invitation is not limited to export customers A little advance notice of any forthcoming visit will naturally facilitate arrangements to have any specific problems covered.

Eric Hicks

We at General Radio have always been gratified by the wide acceptance of our products in Canada, and it is our desire to serve our customers with continually improving efficiency. We believe the above arrangement will further this ambition. Communications either to us or to our distributors w ill receive careful and prompt attention. As always, we welcome direct correspondence with our customers.

Ohm Balanced

Band Balun

As mentioned, the baluns were used unchanged. Somewhat better low frequency performance might be obtained by increasing the number of turns in the windings. However, it is believed that General Ceramics Q 2 ferrite material is used in the cores, General Ceramics recommends this material for use in wide band transformers between 10 and mc so it is doubtful that performance at the lower frequencies could be greatly improved. Since these baluns are used in most TV sets today, supply should be no problem. Various makes of sets were checked and part numbers obtained. Checks with the local distributors of the various brand sets disclosed that most stock the balun coils, However, since Standard Coil

Parts Availability

The varactor diodes(D2 and D3) and most of the integrated circuits used in this project are Motorola devices and are available from Motorola distributors. In many parts of the country, Hamilton-Avnet Electronics is a source for these parts. Excluding the LCD unit, a set of ICs for this project should cost between 45 and 70, depending on which microprocessor you select for your version.

Saxton Spongee

Answer Put a little more in the pot, boy. For 3.29 100' you can invest in our answer to your problem. Spongee uses a porous low-loss polyethylene foam instead of the usual solid plastic, This keeps your impedance relatively flat under all sorts of miserable conditions. It's a littfe more than regular twinlead, but it's cheaper than moving. Saxton Spongee is sold by leading distributors. Saxton goes to the trouble and expense of making the finest twinlead there isj ask for it.

Hamfest Hints

You have to start early with manufacturers and distributors for their available dates fill up fast. Weil-established hamfests start a year ahead with their PR and booth solicitations. The charge for a booth is ticklish for if you set ii high it will keep the smaller Firms out and you set it low you may not have enough money for everything. I would suggest a fee on the order of perhaps S35 per one thousand of licensed dmateure honest ly expected to iUtend for each ten foot by eight foot deep booth. Your booths will include tables and chairs, with tablecloths, plus back and side drapes.

Portable Fm Antenna

A new industrial type, continuously loaded VHF portable antenna. Model HM-5, has been added to Antenna Specialists high performance amateur line. Designed to withstand the rough handling that makes teiescopics impractical, the new spring antenna is completely insulated and cannot accidentally be shorted out. It features a connector fitting that attaches directly to portable equipment with SO 239 connectors. Power rating is 25W with nominal input impedance of 50i2. A companion model, HM-4, is identical except for a standard 5 16 - 32 threaded male mounting base. Both antennas are available from amateur distributors at a suggested ham net price oi 5.95. For additional specifications, write to Amateur Department, The Antenna Specialists Company, 12435 Euclid Avenue, Cleveland OH 44106.

Never Say

If any hams or clubs are interested in helping this project, I think we can furnish a first-rate club station for about 1,500, buying the equipment at wholesale. Part of the bargain is an opportunity to make a visit in a year or two and see the hams which your station has deve -

That Code

Clubs would do well lo contact 73 and buy code cassettes wholesale, passing along the savings to the students or to the ciub, it each studen had a cassette and spent a half hour a dav with it. your code problems would be over Never give code speed tests. Students should copy code at the FCC test speed until they are able to copy easify and know that they are 100 o in their copy. Anything less may cause panic under test conditions.


The method I use requires a minimum of organization as well as the wholesale destruction of the magazines in order to separate the individual articles. For those of us who enjoy collecting the complete set of magazines, this thought is like being against apple pie, motherhood, and The American Way. Nevertheless, information you cannot find is useless, so if you want to keep your magazines intact, I suggest you start in on your first thousand file cards, while the rest read on.

Net Price

Today's best buy in 2 meter equipment is available on the surplus market as a government agency variation of the famous Bendix MRT-i) Packset. This VHF transceiver is available from Metro Electronics Corporation, 172 Washington Street, New York 7, N, Y.( at a cost of 24.95, This is a real bargain by any standards since the wholesale cost of the tubes alone exceeds 65.00. The dual considerations of high performance and low t-ost, coupled with an easy conversion, make the sky the limit for amateur application of this equipment.

Ham At The Helm

The Indian electronics industry had enjoyed a shettered market dominated by the favored few who had been given industrial licenses to make electronic products- One fine day, the Prime Minister made a statement in Parliament, indicating imminent relaxation of these restrictions. What followed was a wholesale liberation of the industry from its shackles. The electronics industry has not yet responded to this move with any tangible results reduced prices or better products. The Prime Minister recently warned the industry to take heed that Government wilt go to any extent to see that the benefits of liberalization reach the common man,


Every so often an article appears in an electronic magazine describing an expanded range line voltage monitor of one type or another. Often a special meter or other component is specified which may not be available to the individual. The circuit which follows uses standard noncritical components which are available anywhere in the the country. If even a meager junkbox is available the cost should not be more than a few dollars. A wide latitude in values is permissible allowing wholesale substitution without loss of accuracy. The original, when caJiibrated against a lab standard showed a maximum error of less than 2 . i'he range is adjustable to fit your needs and may even be adapted for reading 220V lines by making minor changes in component values.

Our Profile

The size and expense of amateur radio equipment for the low bands has been such that interest in mobile operation has dropped tremendously over the last twenty years. In the old amplitude modulation days a little mobile converter and low powered transmitter weren't a big deal The converter played through the car radio and worked fine. Then came sideband and a whole new ball game as far as stability and complexity was concerned. And out went wholesale mobile operation as we knew it in the

Make A Bundle

Distribution in the newsstand field is set up with regional wholesalers, each of which services a hundred or so newsstands. These chaps handle so many magazines that most of them don't want to be bothered with a new One , . particularly ore of such esoteric Interest as 73 They prefer to deal exclusively with national distribu tors so they get their magazines in large bunches and have just one set of forms to fill out for a large number of magazines. After trying two different national distributors and finding ourselves fairly well convinced that this was a bad way to do business, we have cancelled our national distribution sales contracts and are working via local wholesalers exclusively. If you would like to be considered as a local wholesaler please drop our Marketing Manager Sherry Smythe a note and tell her what area you want to cover, how many newsstands you would service, and about how many copies you would like to start with. Yon only have to fiay for sold copies, so you can't...
