Pryvit ('hello') to fellow QRP'rs from the Ukraine, whose national club's website linked to this blog. My Ukrainian colleague gave me these phrases, promising me that they are friendly!
I've built the QFH antenna recently published in QST. The result is very omni-directional, as advertized; but I found the construction rather difficult. Here are some notes on the process.
Lots of progress with 'satpack', my Arduino-based full-doppler-tuning satellite tracking application. On the right, you see a cardboard mockup of the pcb. On the software side, I've checked a fully working version of the code into the SVN repository.
The AA2TX parasitic lindenblad, which was published in Feb 2010 QST (and has been available online for some time), is proving to be an enjoyable project. I have modified some components because I could not find them here in Atlantic Canada. The #8 aluminum wire for the passive elements is not in our big box stores (different wiring regulations?), and the PVC ferrules require a special order, at least at this point in the year, when no sane person would be installing eavestroughing. So I made do with what I had, and the results are encouraging.
