QCX: Alignment procedure video de G0UPL

Hans G0UPL has put together a video demonstrating alignment procedures for his QCX+ kits. The reason for the video was to address common complaints of low power out, particularly with 20m versions of the QCX, QCX+ and QCX-mini.

For those who don't want to build their own QCX+, Hans offers already-built units for sale here.

  1. From Hans (24 Sept):

    On Monday the SMD parts arrived and I have been busy soldering together two QCX-mini prototypes, debugging etc. I now have them both working properly. I built one for 30m and one for 20m. The transmitters produce 5.0W and 4.5W respectively (at 12V supply). Receiver alignment and performance is the same as QCX+.

    This afternoon I connected the 20m version to the antenna and had the first QCX-mini QSO, with Feri HA2EOU who reported 559.

    I have added some photographs of the completed boards here http://qrp-labs.com/qcxmini/qcxminidev2.html

    The enclosure prototype should be here in the next day or two.
