New kit offering

From QRP Labs (Hans Summers - with whom I've had the pleasure to work on the air) - a 5 Watt Transceiver Kit.

Yeah, I know what you're thinking, "5 Watt transceivers have been done to death!".

Well, look at this one!

And here's the 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..5W CW output (depending on supply voltage)
* 12..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)

All for $49 - and available for later this month.  This looks like a great project for the budding, incoming young Ham.  Keep this one in the back of your minds, Elmers!  Lots of opportunities to teach soldering and kit building skills, CW, and operating techniques among other things. The actual Webpage is found at

While I was there, perusing around, I purchased his passband filters for 80, 40, 20 and 15 Meters. Those will be used next Field Day in conjunction with the coaxial stub filters for even more isolation between our stations. Lots of good stuff available at QRP Labs!
