Last night, NCRC wrapped up a three meeting long Club Build Project of a 40-meter QRP Transceiver “Pixie” kit.
We packaged the inexpensive Chinese QRP kit with sockets for the crystal and final transistor, plus two additional crystals (7.030 and 7.040) to go along with the stock Extra Class-only 7.023 crystal. About two dozen of them were purchased by members.
Over the past three meetings, we set up multiple assembly and test/rework stations. All but four kits worked immediately after assembly. Two had cold solder joints. One had a solder bridge. The only “mystery” turned out to be a LM386 that was on the high-side of its maximum current spec, which caused its power source to collapse. Everyone managed to get the right components into the right locations and there were no missing parts. All of the kits produced from 300 to 400 milliwatts of output power.
Willy, W1LY, and Bob, WB4SON, have been messing around with improvements for the Pixie kit for several months. Most of them have been documented on Bob’s website; you can see them here.
The Club wishes to thank our gracious host, KVH, for assisting us with assembly stations and space for the project, along with all the club mentors that were involved.
What might our next Club Build project be? Something Arduino-ish, perhaps?
In addition to a short business meeting 7 PM Monday April 10 at KVH Manufacturing (75 Enterprise Drive Middletown RI), we will have our final Pixie build/test night. Four assembly stations will be available with mentors to help you complete your Pixie kit. Then we will have at least two test stations that can verify transmit and receive function or help debug your assembled kit.
We hope everyone has enjoyed this project and appreciate KVH for giving us so much support the past three months. Many folks have embarked on more ambitious QRP projects as well.
See you tomorrow!
NCRC is embarking on a “Build Night” project that will span our Feb-Apr meetings. We will be assembling a QRP 40 Meter CW Transceiver. Interested parties who can attend the next few meetings are encouraged to visit our Pixie Page, by clicking on Pixie on our menu tabs. You will find details of the project and can even order one or more Pixie boards (which will be delivered to you at one of our upcoming meetings.
Happy New Year everyone!
The first meeting of NCRC will be held Monday January 9 at 7 PM at KVH.
Beyond a short business meeting, Paul, K1YBE, will be describing an upcoming “Build Night” project to be held after the February and March meetings. The project is a simply QRP 40 meter transceiver that can be used by any licensed ham.
