Coming soon: New QRP CW transceiver kit from G0UPL

From Hans G0UPL earlier today:


This kit will be ready and on sale in about 2 weeks, and costs $49 (approx 41 euros, 37 UK pounds). NO more pre-orders, please wait until it is in the shop.

The kit is a single band 5W CW transceiver kit with lots of features. It also contains a WSPR beacon mode. I'm attaching a photo of the prototype with and without the LCD module, because it doesn't show well in the video. List of features:

  • Easy to build, single-board design, 10 x 8cm, all are controls board-mounted
  • Professional quality double-sided, through-hole plated, silk-screen printed PCB
  • Choice of single band, 80, 40, 30, 20 or 17m
  • Approximately 3 to 5W CW output (depending on supply voltage)
  • 12 to 15V supply voltage
  • Class E power amplifier, transistors run cool… even with no heatsinks
  • Good 7-element Low Pass Filter to ensure regulatory compliance
  • CW envelope shaping to remove key clicks
  • High performance receiver with at 50+ dB of unwanted sideband cancellation
  • 200Hz CW filter without ringing
  • Si5351A Synthesized VFO with rotary encoder tuning
  • 16 x 2 blue backlight LCD screen
  • Iambic keyer or straight key option included in the firmware
  • Simple Digital Signal Processing for a CW decoder, displayed real-time on-screen
  • On-screen S-meter
  • Full or semi QSK operation using fast solid-state transmit/receive switching
  • Frequency presets, VFO A/B Split operation, RIT, configurable CW Offset
  • Configurable sidetone frequency and volume
  • Connectors: Power, 3.5mm keyer jack, 3.5mm stereo earphone jack, BNC RF output
  • Onboard microswitch can be used as a simple straight Morse key
  • Built-in test signal generator and alignment tools to complete simple set-up adjustments
  • Built-in test equipment: voltmeter, RF power meter, frequency counter, signal generator
  • Beacon mode, supporting automatic CW or WSPR operation
  • GPS interface for reference frequency calibration and time-keeping (for WSPR beacon)

    1. Hello Bas - Yes, it looks like a very creative design with the built in test functions for alignment.

  2. How about a 3-d printer design (public domain .stl file) for a plastic box/case? This would be available to print in schools, hackspaces etc. 73 de Andy G0SFJ

    1. Brilliant idea and is in keeping with the rig's intended "RSGB Youths On The Air summer camp buildathon" project.
