Hints and circuits can be found in the ARRL handbook in the chapter on specialized com- munication systems. Hqw to put a man down The R F Patch .
It was intended to do wonders on and 20 meters. How did Gotham drastically cut antenna prices?
I am assuming tliat you have located and marked with stakes aU of the buried pipes that cross your property. He’d then spent the next four hours frantically chasing an elu- sive radio contact, nearly at the antipodes. For many years I have had tiansmitters and receivers with Meter coverage.
This arrange- 2m3643 was not tiled, however. There is a slight insertion loss of about 5 dB for the filter. Mine twisted off in very mod- erate weather, Paul A. Self-powered and solid state, it is easily installed in the mike tine of either fixed or mobile station. It was a good antenna, but witliin a week, die end of the 5 inch pipe above the roof liad become solidly fro- zen to the Ross Ice Shelf, Needless to say, it was not rotated mi til the temperature got warmer and then it went datasheeg and round like a windmill, when the gale winds came up.
Strip that wire— segregate that aluminum, dahasheet and copper.
We charge ham-type prices for fixing ham 2nn3643. However, if you are an ”operator” only and not able to repair and improvise, perhaps you’d better think tvdce before packing your seabag be- cause most of the equipment on U.
They both work in the same manner. After all, the sunspot cycle was definitely on the way up. And she’s been behaving just as well ever since. The rig The basic aim hi this gambit is to ap- pear to do a slightly better job than the other feUow. The harm that he has done is incalculable. Compact 3″ x 5″. Since many of the popular VFO’s for the six meter band operate at fundamental frequencies of 8 to 9 MHz and are using the transmitters multi- plier stages, with a multiplication faction of six to obtain output frequencies of 50 to 54 MHz, the actual frequency deviation at the VFO s fundamental frequencies datashert very small, percentage wise.
At the present time, due to retirement of regular operators, generous vacation plans days a yearand the activation of over a hundred moth-balled ships for the Viet Nam war, there has developed an acute shortage of merchant marine radio officers. This mode of operation is effective, but it turns out to be uncomfortable, if not downright dangerous, due to the high dc voltage which appears across the terminals of the key.
A very high pole was as necessary to the garden as the roses. So, be specific if your DX friend directs you to answer only cards with proper return postage.
All suggestions used will he rewarded with a merchandise certificate- Con- tact us now at: Usable for auto, home and transistor radios.
Not by a long shot; her debut was made her first day on the air by datasgeet up a mile contact in broad daylight with a readable signal re- ported! I would be interested in hear- ing from anyone who is doing work with multiplex.
The history of Operations Deep Freeze III and the International Geophysical Year has been published in many magazines and books but little has been told about the mo- mentous part amateur radio accomplished during this operation and still continues to do today. Commercial equipment reviews will usually be rejected unless you are well known to us and have done writing for us before.
No detectable birdies from surplus oscillator products— you put the crystal in and you’re right where vou want to be. The system goes like this: 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 would result.
Its size and weight permit it to be easily rotated by the AR TV antenna rotator. It was a close race with a hazeleyed blond from Tennessee but Miss Massachusetts won in the runoff. The receiver was being used only as a sensitive rf voltmeter with no caHbra- tion being necessary except for a constant S-meter reading.
How she had tried to interest him in herself, in her own lovely world of knitting, embroidery and flowers. That made a believer out of me, but quick.
When this is ob- tained, cramming is concentrated on the more difficult element six since credit is giv- en for the elements already passed in ob- taining the third-class license.
2N3643 – SI NPN LP HF BJT
Besides J those participating were entitled to free trash pick-up and what dedicated ham would resist anything free. If the signal generator has its attenuator calibrated in dB, then no slide rule work is needed, only the subtrac- tion of one reading from the other, Tests were made on a number of relays over the range of from 28 to MHz.
Amateur radio has friends in high places in the ITU and in many foreign govern- ments. In conclusion J when your DX station fi- nally leaves his DX location and closes down, you will still receive cards for him- I have been receiving for one station as far back as two years.
