QCX (20m) completed, aligned, tested

We woke up to a rarity this time of year in this part of the state - snow. Just a dusting but it adds a seasonal accent to the area we don't normally get. Add coffee and the last remaining parts of a QRP kit and you have the ingredients for a fine morning.

About an hour's worth of still-in-my slippers soldering and the kit was finished. The alignment went well and all the parts were smoke-free.

The snow on my Yagi (okay, no more mention of our snow) did nothing to hinder its SWR and, while my initial CQ with the new rig didn't yield a QSO, I did receive several reports on the Reverse Beacon Network. This was a bit of a surprise as I was using the built-in microswitch hand key.

The Morse decode function of the QCX had no problem decoding my outbound CQ or in displaying the text of other stations I tuned to although a bit of lag is noticeable when tuned to stations that are sending at 25+ wpm or so.

Power output with a 9V battery was 2.5 watts.

This kit also has the ability to operate as a WSPR transmitter with GPS control of timing, frequency calibration and grid square determination. I have not yet used it on that mode but will soon.

UPDATE:

Just had my first QSO with the QCX and it was an interesting one. My 14.060 MHz CQ was answered by Ron WA7GIL who was set up at a roadside rest area in Congress Arizona for a day of portable hamming with his brother. Ron was using an FT-817 on 20m and his brother (using a KX2 on 40m) has a 30m QCX under construction at home.

Ron is familiar with the QCX and told me that mine had a "nice clean note". Thanks for the FB chat and the photos Ron and 73!

  1. Hi, John!
    My congratulations!
    I am still waiting for my QCX-20m... hope to get one as Cristmas gift :-)
    May be in the future we make transatlantic QSO QCX<->QCX!
    (If propagation gives us that opportunity!) :-)

    73!
