AF4K's QRP - THE ART OF LOW POWER RADIO

The challenge of QRP is to operate and/or build CW (Morse Code) or voice (AM & SSB) radio transmitters (& simple receivers) for the amateur bands using a bare minimum of components, money and construction skill; equipment that is useful for radio amateurs looking for some diversion beyond their regular pursuits. Note that you need a license to transmit with this equipment!

Anyone with a suitable amateur radio operator's license and a lots of cash can buy a 3,000 watt computer-controlled rig and contact Antarctica and Swaziland via SSB or send digitized images of their pets across the globe! For the rest of us, QRP and homebrewing is more practical and often more interesting to see just how far 'flea-power' can go (QRP is a Code signal meaning 'decrease power' and has been adopted by amateurs working with an output power of 5 WATTS or less). Homebrewing: building your own simple equipment, makes it that much more interesting and satisfying.

One of the biggest thrills for me came at the peak of the sunspot cycle in about 1982 when I owned a converted CB radio. My first QSO on 10 metres with this rig was with a UL7 in Asia!! That was into a three element yagi at 35 feet, BUT I also used to run it mobile in my car, and sometimes contacted hams in JAPAN with it! All with just 10 watts! Not bad eh?

I have mostly lost interest in QRP while living in an apartment for a few years and after being treated extremely rudely by some of the QRP operators on the QRP-L E-mail list! I strongly discourage you from getting involved with that group or their leader!

This showed up on QRP-L internet, and I just copied it off the NJ QRP webpage. This is an announcement of a milliwatt xmtr kit you can put on several bands. The cost is only $10. so could be considered a "stocking stuffer". Hope some of you will give milliwatting a try, and take a look at this affordable kit from NJ QRP club. 72/3'z de Jim KJ5TF AR QRP #2

The NJ-QRP Club is pleased to announce availability of a small, cool and fun "stocking stuffer" QRPp transmitter for all to enjoy: the Jersey Fireball 40.

One of our club elmers, Clark Fishman, WA2UNN came up with a couple of twists on the popular theme of using a TTL crystal oscillator "can" as the heart of a milliwatt-level transmitter. The basic transmitter was previously published a number of years ago in "73 Amateur Radio Today", Radio Fun" and in our own QRP Quarterly, and he decided to brush the dust off the design and extend the functionality just a bit for the holiday season.

Clark chose an oscillator can frequency of 28.322 MHz as a starting point, added some simple circuits to divide down the fundamental frequency so as to hit 80m, 40m, 20m as well as 10m. Being the technical purist he is (or as much as he can be in this category of projects), Clark also decided to put a low pass filter on the design ... AND we've provided pads on the printed circuit board for a TiCK keyer chip! All you have to do is drop in a chip and couple of components from the Embedded Research guys and you'll be paddling to your heart's content. This is one feature-packed little bundle!

This little transmitter was christened the "Jersey Fireball 40" ... the design puts out about 40 milliwatts, and we're providing the filter components for 40 meter operation. Jumper-selectable band operation will allow you to operate on the fundamental of 28.322 MHz, or on 14.161 MHz, or 7.080 MHz, or 3.540 MHz ... it's your choice!! And if you want to turn your project into the Fireball 80, Fireball 20 or Fireball 10, just substitute some L's and C's from your junk box per the filter charts provided.

Okay guys, now here's the real kicker ... the NJ-QRP gang is kitting up the "Jersey Fire-ball 40" and making it available to the QRP community for only $10, postpaid anywhere. Ten dollars! Oscillator can, voltage regulator, divider IC, filter components, pcb with pads for a TiCK keyer, and a *real* nifty instruction sheet and web page construction guide. Ten dollars! We got a fabulous deal on the parts and we're passing it along to everybody here as a holiday deal. Did I mention that this kit is only $10? :-)

The Jersey Fireball 40 isn't going to get you any trophies in the DX contests, any pelts in the Fox hunts, or any ooh's & aah's in the "bells & whistles" category of equipment in your shack ... BUT this this little gem will go together in about 15 minutes and provide all sorts of amazing contacts for you. See how many miles-per-watt you can get with just a 9V battery and antenna!

You can order the Jersey Fireball 40 with a $10 check or M.O. drawn on a U.S. bank, made out to "G. Heron". Send it to: The NJ-QRP Club, 45 Fieldstone Trail, Sparta, NJ 07871.
