The 'Rock-Mite '
The 'Rock-Mite' design grew out of my desire to offer a 'one-evening' CW transceiver kit which would be both affordable and easy to construct. It first appeared at 'Lobstercon' - a QRP gathering on the Maine coast- in early July, 2002, where it was provided to all attendees courtesy of Small Wonder Labs and the NorCal QRP club.
You'll note in the image above that the Rock-Mite uses two crystals. The first is used in the local oscillator for transmitter and receiver. The second is used as a receiver front-end filter. This crystal significantly reduces the 7100-7150 khz SWBC energy present at the receiver mixer; as a result, unwanted SWBC reception is dramatically reduced.
The Rock-mite uses one surface-mount part with fairly large spacing. There are no toroids to wind, so assembly should be a snap! The Rock-Mite uses subminiature epoxy-encapsulated RF chokes instead of toroids- maximum harmonic content is -34 dBc.
- Double-sided PCB 2.0" x 2.5", plated-thru-holes, solder masked & silkscreened for easy assembly
- 0.5W power output at 12V supply.
- Supply voltage range 8-15V
- Tuning: fix-tuned, ~7029/7030 Khz (14059/14060)
-automatic T/R offset, reversible
-Built-in Iambic keyer, 5-40 WPM
-Built in sidetone, 700 Hz
- Includes assembly instructions and operating tips
- All on-board parts supplied in kit (as pictured above)
40m European Version, incl 2 7030 kHz Xtals
Please Note: There's no enclosure kit available for the Rock-Mite. It's 'Altoids-compatible', however, so a source of enclosures is probably as close as your nearest market or pharmacy!
As an AddOn we offer a Peripheral kit with all parts including a Fishermens or Altoid box.
