Guy Wires Underfoot? Something Ain’t Right

Also: Yawcam freeware keeps an eye on things

As a kid I played a game with my sister in which we stacked a bunch of dominoes and then tried to remove one at a time before the entire stack tumbled over.

Fig. 1 is a takeoff from that game. How many guy wires can you remove from an AM tower without it falling over?

Hey, look, it’s still standing in Fig. 2. But I can hear the owner now: “Ahhh, it’s only AM …”

Aaron Read, general manager of WEOS and WHWS in upstate New York, comments on an article by Leslie Stimson in the Dec. 15, 2010 Radio World that discussed cellular phones with FM reception.

An issue of note is that several higher-end “smartphones” such as the iPhone and Motorola Droid have physical hardware for FM radio reception but lack software support for accessing that hardware.

Some enterprising hackers have figured out ways to “get at” all sorts of hidden features on these phones, including activating the radio. For example, the Motorola/Verizon Droid X has software support built in for its radio while the Droid 2 does not. Yet there’s a hack available on the XDA Developers forum that unlocks it; see

If you’re not sure whether your phone has latent radio capability, try doing a quick Google search combining the names of the carrier (AT&T, Verizon, etc.), the phone manufacturer (HTC, Motorola, Samsung, Apple, etc.), the operating system (Android, iPhone OS, Windows Mobile 6 or 7, etc.) and the phone itself (Droid 2, Omnia, Defy, etc.), along with the word “radio.” This likely will turn up any information.

As one might imagine, there tend to be more hacks for the Android OS thanks to its more open architecture, but there are some for Apple and a few for Windows Mobile, too.

Aaron has encouraged visitors to his station websites to listen using their Droids or iPhones. Great cross-promotion. Visit

Lew Wallach, N9WL, is not only a ham but a CPA. Having read our tips in the Dec. 15 Workbench on emergency preparedness at the transmitter site, Lew offers the following:

Use metal or glass containers to store food. Rodents will eat through a plastic container to get to food stored within. Any clean metal container can be used, since the food is packaged (no chemical reaction).

Put several rolls of toilet paper in a gallon freezer bag to keep them dry. Ditto for your paper towels.

Lightweight aluminum/Mylar “space blankets” reflect body heat. Make sure you have two or three of the pocket-size packages per person, or at least one “stadium” size blanket (larger, thicker and reusable).

Fig. 3: Yawcam is free. The name is short for ‘Yet Another Webcam software.’ During a backpacking trip that tested Murphy’s Law, Lew says his stadium space blanket made the difference between discomfort and hypothermia. He only has experience with the Thermos Space Blanket brand; a number of manufacturers make such products, available at nearly every outdoor store and even Wal-Mart.

He adds that emergency survival equipment is not the place to try saving a few dollars.

Lew also has a tip for soldering. A stainless steel scrub pad cleans his soldering iron tip better than a wet sponge. A budget-busting three-pack for $1 at the local Dollar Store will clean a lot of tips. They also are handy to stuff inside conduit and other insect and rodent access points. They don’t rust and the rodents haven’t eaten through them — yet.

Atlanta engineer Allen Alleo calls your attention to This freeware is webcam software written in Java, simple and easy to use but with the usual features.

Yawcam features include video streaming, image snapshots, a built-in Web server, motion detection, FTP upload, password protection and time-lapse movies. You can protect your transmitter site inexpensively. Although Yawcam is free, consider making a donation if you find the software useful.

Failures From Wire-Wound Resistors

One of the best things you can do to foster teamwork among fellow department heads is to pass on useful information. For programmers, it may be a new feature that your hard drive automation system will perform.

Starting the New Year Off Right

I've been fortunate during the past year to receive and share a number of pictures of problem sites with readers of this column. To be fair, these sites are in the minority. So to give balance, I'd like to focus this column on things that were done right.

Shocking Uses for 'Audio' Wire

Joe Stack with Modulation Sciences is an occasional contributor to Workbench. In discussing poorly engineering sites, Joe says he has run across two scary uses for Belden 8451 audio cable.

Doing It Right!

Longtime friend John Francioni with Capitol Broadcasting in Raleigh, N.C., loves all the "how it's done wrong" pictures that have appeared in this column over the years. But, he says, how about some photos where the engineer has done it right?

Zip Up Annoying Wire Bundles

Rick and his engineering consultant, Ted Schober, had been troubleshooting an intermittent VSWR trip that seemed to be coming from their LPB transmitter. The trip would show up on the remote control, but for no apparent consistent reason. One day it was wet, another dry, one day it was warm; you get the picture.
