NOTE: THIS IS A PRE-ORDER. The first 1,000 are sold out. The next batch are being manufactured, expected shipment date is END January 2021.
The "QCX=mini" (QRP Labs Xcvr - 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). Available for 80, 60, 40, 30, 20 or 17m bands. Experimental use on 15, 12, 10 or 6m (lower power output and reduced sensitivity). For complete details see http://qrp-labs.com/qcxmini
The yellow/green LCD has a backlight which can be switched on/off via the menu system or double-clicking the rotary encoder shaft button. This provides current consumption savings; furthermore, low-current operational amplifier ICs have been used, resulting in a Receive current of only 58mA (12V supply, backlight off). The LCD is daylight and even SUNLIGHT readable without the backlight.
The Optional enclosure is black anodized extruded aluminium, very sturdy and elegant. The enclosure size is 95 x 673 x 25mm without protrusions. The top and side panels are drilled and cut to match the QCX-mini with laser-etched lettering. The enclosure includes four self-adhesive feet.
Optional 25MHz TCXO module is pictured above (diagram only, as yet). In tests, the frequency change over the range 4C to 65C was +/- 0.25 ppm (parts per million). This is a tiny 14.8 x 10.5mm PCB with TCXO, SMD all ready-assembled, which is installed onto the main QCX-mini PCB in place of the 27MHz crystal and 0.1uF capacitor C2.
Hard-copy assembly instructions are not included in the kit. You need to download the assembly and operating instructions manual from http://qrp-labs.com/qcxmini
Note: The QCX-mini transceiver is always shipped with the latest firmware version available at the date of shipment.
Note: the optional GPS receiver module kit is very useful if you wish to operate this kit as a WSPR beacon (it disciplines frequency, time, and Maidenhead Locator grid square). It is also useful for calibrating the transceiver kit, to get the synthesiser reference oscillator precisely calibrated (resulting in accurate transmit/receive frequency).
An optional 50W PA kit is available, which also has an optional enclosure. This 50W PA kit will give your QCX an extra boost for those occasions when you need a bit more power - to work a particular station for a regular sked when conditions are bad; to deal with our bad band conditions these days; to work a particular DX staiton, etc etc. The 50W PA kit includes solid state Tx/Rx switching for full break-in (QSK) operation. The kit includes heatsinks and connectors as well as the PCB and all components. See http://qrp-labs.com/50wpa for more details.
