ARRL Homebrew Challenge
The deadline for the ARRL homebrew challenge has passed and I hear that the
ARRL received 4 entries, all NO computer radios. NONE were in the computer assisted category. Publication is scheduled for Feb 2008 QST A Yahoo group was started to discuss developments. http://groups.yahoo.com/group/ARRLHBC/ Some of the entrants have posting info about their entries there. |

Part of the reason might be that building piece by piece is getting
pretty expensive for what you end up with. For $700 or so, you can buy a radio that works all the HF bands plus 6, 2 and 432 with all kinds of features. Try homebrewing that for $700... :( Seems that most stuff homebrewed these days is station accessory equipment that just makes some task around the shack a little more convenient (I'm guilty of this as well). I do still hombrew all of my own antennas :) Scott N0EDV geek wrote: On Sun, 28 Oct 2007 20:10:27 +0000, John Tartar wrote: The deadline for the ARRL homebrew challenge has passed and I hear that the ARRL received 4 entries, all NO computer radios.

By the grace of Analog Devices in their enlightened policy of providing samples of even their most expensive devices, and the price of SMD ((NOT really so difficult to work with, just different. And you purchase new resistors and capacitors at $0.003 each (Not a typo, 3/10ths of a cent) from DigiKey!)) Mine came in at something under half your $700 figure for a 160-10 meter transceiver with more bells and whistles than the average $2000 radio, and more performance than most radios costing twice that!

W4ZCB Well, Really not a typo, but at $0.31 for ten each, for the mathematically unchallenged, that comes out to THREE cents each. Going to have to go sweep up all those that have flipped out into never never land, hardly ever to be seen again and restock my supplies. Them things is more valuable than I thought. (Although I HAVE purchased SMD parts as inexpensively as $0.003 each at hamfests) Regards W4ZCB |

That's astonishing.

There was a really funny letter that QST published over the summer, saying "there's no way to do anything on HF without a $6000 radio and multiple towers filled with beam arrays anymore". My response: I turned on my old Heath HW-16 (paid $50 for it a few months before) and worked a dozen European/Eurasian countries and Senegal without even trying. It's like some are setting the bar way too high or way too low, when really it's about having fun. Tim. |

After the designs are published and we don't see a huge influx of new hams, I think we'll finally be able to abolish the thought that sub-$50 radios aren't the silver bullet and move on to facing the real challenges instead of stupid lines in the sand.

Well $50 is definitely Do-Able, for a SSB/CW radio.
There's a picture of one on the front page of the yahoo group. http://groups.yahoo.com/group/ARRLHBC/ The fact that the are only 4 entries is a little disappointing, especially since none were Software Defined Radios. However, the task is difficult, and the prize was only a token $100. I know of a few hams who started designs but didn't finish in time. I've looked at the Picastar group, and that's real homebrew, they want you to iron Xerox paper onto blank PCB stock to make your SMT boards. So it's $300 in material, and probably 300 hours of your time. But saving money is not the normal reason for homebrewing these days. For $300 you could buy a decent used 160-10M HF radio on EBay. The first radio I built (in the 60's) was a simple 1 tube crystal controlled transmitter featured in an Electronics magazine that you could build for $7. Adjusting for inflation, $7 is about equal to $50 today. And for $50 you get much mo a VFO, digital readout, TX&RX, CW&SSB. I think the point of the $50 HF radio, is to attract VHF only hams to try HF. What's the statistic? 75% of all hams never operate on HF? The new no-code license should let these Tech class hams get a general pretty easily.

Hi,

I'm not an RF collector by any means, but a HiFi guy and I'm sure I have enough stuff kicking around to make such with a $0 output. I did breadboard a tube SSB exciter for 27MHz... dunno of its spectral purity but it got out *shrug* Cheers, __ Gregg |
