|Nate, I wasn't suggesting commercial distribution, just friendly "would you mind passing along your QSTs to me, you know I'd love to join ARRL but money's a little tight now..." kind of redistribution. Watermarks won't help here.
I share your view about not assisting freeloaders. I used to bring my old copies of QST to our radio club meetings, but then I decided that folks who are sufficiently interested in the hobby to join a club ought to be paying members of the League. That's when I started dropping them off at the library.
I also agree that HQ should talk a bit about the decision-making behind the selection of nxtbook technology; maybe a topic for one of Harold Kramer's Inside HQ columns.
|What to do with a dish network dish?a||KC9UNY||on 11/3/13|
|Is there any creative way to use a Dish antenna as the basis for an HF antenna? Developments with CC&Rs must allow satellite tv antennas by federal law, so I am wondering if anyone has tried using the framework of the Dish antenna as the basis for, say, a spiral-wound long wire stealth antenna.

|I'm sure that the reason they don't do PDFs is security; those PDFs would be going out to fellow hams who choose not to join ARRL. For those of you with iPads, there is a QST app, but it suffers even more from the same fuzziness and slowness to load criticized here on the PC version.
I find the online version only really useful for one thing. I prefer not to keep my old QSTs, so I have in the past copied interesting articles and then passed them on. Now I don't have to copy stuff out of the magazine, I can just print the pages of interest. The paper copies go to our local library's magazine exchange table, where perhaps they may inspire someone who always wanted to be a ham to study up and join us.

|I found my own solution, and thought that I would post it here in case anyone else stumbles across this thread. Basically, the report of a trojan in the USB installer that Zadig created is a false positive (see discussion, including results of an Avira staff test of the file, at http://sourceforge.net/mailarchive/forum.php?thread_name=50F3EEFB.2010006%40gmx.de&forum_name=libwdi-devel). Turn Avira off, run Zadig, then turn it back on again.
I picked up an inexpensive DVB-T dongle from Amazon (http://www.amazon.com/gp/product/B008BQV25M/ref=oh_details_o04_s00_i00 but it is now out of stock) which was shipped directly from Shenzen, China. I plugged it in to a Gateway Netbook running XP, ran the script referred to in the article, installed the driver, and then ran SDR#.
I used the tiny TV antenna which shipped with the dongle, but heard nothing at first, even after tuning to powerful local FM stations (using the WFM setting) and to our local NOAA weather radio station (using NFM). Nosing around SDR#, I noticed a Configure button at the top, clicked that, and found an RF gain control turned, by default, all the way down (!?!). As soon as I moved the slider about halfway, I started picking up FM and weather broadcasts. I never had so much fun for such a small investment; my dongle was $20 and I spent another $7 on a PAL-to-BNC adapter for the antenna. Incidentally, my dongle's PID and VID don't exactly match any of the products on the list of dongles known to work, and the description in Zadig was RTL2832U, not "Bulk-in, interface" as described in the rtlsdr.org guide to Windows software. My takeaway is that this is an area where being a little adventurous pays off.
W9RAN, thanks for inspiring me to pursue this.

|Robert Nickels article in the January QST was exciting, and inspired me to try out SDR using a DVB-T dongle acquired from Amazon. As suggested both in the article and its update on QST In Depth, I downloaded a batchfile which downloaded the necessary software. When I ran Zadig to install the WinUSB driver, my Avira antivirus software picked up a trojan called TR/Crypt.ZPACK.Gen7 and would not let me proceed with the install. I'm running XP Home SP3 on a Gateway LT20 netbook with a 1.6GB Intel Atom processor.
Without the ability to install the driver for the dongle, I'm dead in the water. Has anyone else encountered this problem and, more importantly, is there a workaround, another way to get the WinUSB driver onto my system and associated with the DVB-T device?
