A Solid Wall of RF

When I find something that works, I buy a lifetime supply. One of those rare things was a small FM transmitter with digital readout.

You might remember these little transmitters. Before streaming was cool, one could take a laptop with a wireless network card (EVDO in those pre-LTE days), tune in Wisconsin Public Radio and transmit it on an open FM frequency to the car radio as one drove down �the 101� (that�s California-speak, where all highways begin with �the�).

Not a bad trick�listening to a pseudo-radio playing the cheesehead informational hits while cursing the LA traffic.

You really needed to pull over to �tune� it, but I do know that it would not disconnect from San Diego to Santa Barbara � a run of about 200 miles, give or take.

One of the neat things was that there were only a few open �slots� on the FM dial, so when I shut the little transmitter off, I could hear an endless string of cars on the highway dip in and dip out with whatever tape or iPod-type device they were listening to.

Within a few years, the open slots weren�t so open, especially when a Franken FM took that magic 87.7-87.9 slot.

My listening habits were saved, at least temporarily, when one manufacturer produced a high-quality (read: more than Part 15 power level) device that would kind of blow a hole open on the dial. One could hear these a block away, so of course, some broadcaster called foul, and magically, the imports stopped. I thought I had bought a lifetime supply, but alas, poor construction and design limited the device�s lifetime.

In the end, it made more sense to buy cars with USB slots, two outlets � one always on, one not � a mini-plug and Bluetooth. Today, I really don�t want to drive a car that doesn�t have those.

When it comes to rental cars, half the time they don�t have all of that stuff, and the other half of the time they block the Bluetooth; that means I have to consume radio like a �normal� person.

And that is easier said than done.

I�ve taken to making a checklist: Adjust the mirrors, check for damage, make sure there is gas in it �and then set up the radio and familiarize myself with its quirks.

Some of these radios really did have me reading the manual and googling �how-to-dos.� The last time I rented a car, I chose the same model as the car I own, just so I didn�t have to learn how to use the radio � but even that didn�t work! The model year change incorporated a completely different user interface.

I can�t believe I just said �radio� and �user interface� in the same sentence.

Two knobs and a dial do a pretty good job. Nested menus and mixing tactile and touch screen controls give you access to lots of features, but all I want to hear is a traffic report and maybe scan to see if there is something interesting, like a reggae station. Listening to the radio should never be this hard.

I like towers. Eiffel tower, CN Tower, Sutro, Freedom Tower, Devil’s Tower, Tower of London, broadcast towers, or the ham tower that protects the house from lightning
