The Cricket is a low cost entry level minimalist CW transceiver for the 80 meter band. Chosen as the build session kit for OzarkCon 2017, it bears a family resemblance to the well known but much lower performing Pixie, but is higher powered, and has a much better receiver. It features low parts count, a MOSFET PA/mixer, and a modern NJM2113D audio amp. Originally developed for the Four State QRP Group, the kit has been retired by them, and now brought back into production by the designer.
A TX/RX offset is also included so that you can work other stations that have zero beat, or you are using a crystal on the same frequency. Full QSK and a sidetone complete the essential operating features. The PA filter inductors are implemented as etched spiral coils are included on the pc board, so there are NO TOROIDS to wind. Additionally a straight key is included on the pc board, just snap it off, mount it on the board, and the whole rig is then self contained. Also included is an electronic keyer adapter - you can use your favorite keyer with the Cricket! These are many unusual features for such a low parts count and inexpensive transceiver.
ALL THROUGH HOLE parts make this kit very easy to solder together and assemble. It will make a fine, fully functional, and educational first rig for a new builder, the new ham, or seasoned veterans wishing to just have fun with a new rig at minimal expense and effort. Note that Novices and Technicians have 80M CW privileges from 3.525 to 3.600, same as everyone else - so they also can build and use the Cricket.
This kit was very favorably reviewed in the December 2017 issue of QST.

The Cricket was designed as a simple, low-cost CW transceiver that could serve as an excellent kit for beginners, but has performance good enough to get on the air as a usable radio.
The Cricket kit is a self-contained CW transceiver, with built in battery holder, spiral PCB trace inductors, on-board morse key, and included crystal. You can literally be on the air making contacts within an hour of opening the kit envelope!
