10th Anniversary Giveaway!

On April 30th, it will be ten years since the "W2LJ - QRP - Do More With Less" blog was born.

In appreciation for all who read this blog, I am going to give something away to one lucky reader. I have a new, mint condition, unused, complete sheet of fifty United States Amateur Radio stamps, issued in 1964 on the 50th Anniversary of the ARRL - Scott #1260. I am going to have the sheet matted and framed - ready for display on some deserving shack wall. All I ask is that you send an e-mail to w2lj@arrl.net - entitled "Blog Anniversary Giveaway". Include your name, call sign and mailing address.

Any Amateur Radio op worldwide can enter. I will package and ship the framed stamps to any destination that the United States Post Office will accept.

The names and call signs will be loaded into a software program such as RandomPicker on April 30th and a winner will be determined. The winner will be announced here, and then the framed stamps will be posted.

Good luck, and thank you for reading!

PigRig Transceiver

Diz, W8DIZ of Kits and Parts dot Com, has come out with a new transceiver kit - The Flying Pigs "PigRig".

It is a single frequency transceiver.  Sound strange?  Maybe it is, but listen to Diz's own words:

"This transceiver was designed for Radio Clubs and/or Special Events. You turn the radio on...you listen...you do not tune...you do not switch anything...you do not search. If you hear someone on "your special frequency", there is a good chance it could be a member of your group.

Here is what it is and is not.

It is a club radio.
It is not another me-too qrp contender
It is a single conversion design
It does not receive 2 sidebands...only one
It does have a full 5 watts output at about 13.6 volts
It does not have any tuning controls
It does have a piggie custom keyer chip
It is like a ham version of Channel 19 using CW only

The size of the PCB is only 2.5" (63,5 mm) by 3.8" (96,5 mm), and Yes...it does produce a full 4.99 watts RF out and it is as sensitive as just about anything else that you may have in your radio shack. Custom club/group frequencies are available for 40 meters. The name of this radio shall henceforth be labeled as the "Flying Pig Rig".

Thanks Larry.
Looks like a fun rig from Diz. Not a "me too", but nothing we have not seen before. Examples: the QSK circuit from the Ugly Weekender, NE612 mixer into an LM386 AF chip (might be the millionth rendition we have seen), MOSFET/JFET switching ala 1980s to present. BD139 - the new popular NPN power transistor.
A good effort by Diz for a 1 channel transceiver.
