Nov 30, 2017 · “Unboxing, building and using the QRP Labs QCX single-band, 5-watt QRP radio. This advanced technology radio borrows ideas from software-defined radios. The final amplifier is Class E. It’s relatively easy to build, although probably not a good first kit. I really like this radio and hope it continues to sell well.” I wish to build a separate receiver for 6m WSPR so that I can use my FT-690Rii for QSOs. And besides, the FT-690Rii isn't very frequency-stable. I have read in the QRP-Labs web pages that the QRP-Labs Receiver Module can do this if one makes a modification and feeds it with 2 local oscillators 90 degrees out of phase with each other.

The Heathkit HW9 The DL2AVH receiver is direct conversion and there are separate oscillators to drive the receiver and transmitter. It seems to have been corrected in 2007 and a printed circuit board seems to have been designed also. But I don't have the final documentation, it may however have been published in the German QRP-Report at the time.
This GPS receiver module kit includes an extremely sensitive patch antenna, with factory pre-soldered Mediatek chipset RF module. It has three onboard LEDs for visual status indication, 3.3V regulator and power supply filtering, and 5V logic level conversion. It's easy to build and directly compatible with all QRP Labs kits. “This kit replaces my old station clock, which I managed to zap, with a new one with its own dedicated GPS receiver. The kits, from QRP-Labs.com, are something you can put together in one evening. Note you will need a source of 5v power. The video is devoted to constructing the two kits and showing the finished product.”
The "QCX=mini" (Q RP L abs X cvr - mini): a feature-packed, high performance, single band 5W CW transceiver kit with WSPR beacon and built-in alignment and test equipment. It is designed specifically for portable operations where small size, weight and current consumption are all important (see Special portable-friendly features section, below). The photographs above show how I built this QRP power meter right inside the RF output (antenna) connection of my Ultimate3S QRSS/WSPR transmitter in its officical QRP Labs case. The meter stays wired in during operation and doesn't significantly affect output power.

May 02, 2016 · 238C – 2KW High Power Antenna Tuner Model 238C now features a large cross needle SWR and peak reading power output meter. Model 238C uses our tried and true L match design used in the earlier 238 238A 238B models with a new cosmetic design, larger heavy duty tuning capacitor than the original and backlit cross needle SWR and peak power output metering. This compact "QRP" or low power radio kit from QRP Labs in UK was too good to resist. The radio is based around an IQ phasing receiver for CW (morse) and an Class E efficient transmitter.
Jun 18, 2012 · You can check for chirp by listening to the keyed output of your QRP+ (run it into a dummy load!) on another receiver, or by on-the-air tests with a local ham. It is most instructive if you can actually listen to your signal -- either in a local receiver or over the phone from another ham.
