It lives! Testing it out on the dining room table. Here are my instructions to get it up and going, in American English:
Quickly scan the 4-page "manual" the day before connecting.
Tear open box and remove the Xmitter.
Do not plug in the power cable until you have connected the antenna, ever.
Screw the antenna onto the back of the unit. Important to do this first, before connecting anything else.
Grab the heaviest package and open it, wondering what it is.
Realize that it is an antenna stand.
Unscrew the antenna from the back of the Xmitter and screw it onto the stand.
Screw the antenna cable from the stand into the back of the Xmitter.
Plug the provided 3.5mm to 3.5mm cable to your source, or use RCA to 3.5mm cable (not provided - that's okay, you've got about forty somewhere) if necessary. I was testing with my Zune, so the provided cable made it unnecessary for me to spend an hour finding one among the twenty or so I have, carefully rat-nested with many other various cables. The 3.5mm end remaining plugs into the front of the Xmitter on the left side, Audio-In. The other, on the right, is clearly Mic-In so not even I got that wrong.
Plug the power cable into the back of the Xmitter before plugging the other end to 110 - get the order right here or you might see sparks warns the seller (in-line power supply doesn't block other outlets on your already-overloaded power strip - yay!).
Plug the power supply into 110v outlet.
Press Power button.
After a few seconds, when the alarm starts it's piercing beep, beep, beep, push all the buttons at random, watching the display.
When anxiety reaches its peak, with your wife shouting at you to turn off the alarm, shut down the power and find the manual and your lighted magnifying glass.
As you read, realize that pushing the antenna across the table was likely a bad idea, and re-locate it further away from Xmitter, at the end of its fifteen-foot tether, realizing now why they included the stand with 15' cable.
Press power button to turn back on (standby/transmit are press and hold).
With no alarm now disconcerting you, scroll through the short, simple menu with quick-presses of the Power button.
When FWD (followed by bars) begins flashing, stop quick-pressing the Power button, unless you pass it up, then keep pressing until it comes around again (very quickly) quicker than you thought it would so keep quick-pressing until you inadvertently stop with FWD flashing and all bars lit up.
Press down-arrow button until no bars are lit up, which is the 1.9 watt setting - the unit's lowest.
Refer to manual again for which icon lets you adjust Xmission frequency and set that with menu and up/down arrows to your predetermined broadcast frequency. In my case 97.7, determined using Radio Locator.

Check chart in manual for the precise antenna extension in inches for your frequency, then eye-ball it like I did 'cause you don't want to look for your measuring tape right now.
Start some music. Turn on a tuner or grab a radio, or both, as I did
Turn your source up. Adjust the volume of the Xmitter's Audio-In to about half way.
When you hear your new radio station, smile, because it sounds better than you thought it would, unless your expectations were unreasonably high for this type of device at this price.
Look at any clock. It's only 2:00 AM. Hand your wife your Sangean DT-160, or order one now if you don't have one 'cause it's a winner. Ask her to walk around outside to check range.
"What is this?"
"It's our new radio station."
"I thought that was the thing on my table. What is this you're handing me?"
"Cheese 'n' crackers, baby! It's a radio and headphones! People often use them to test their new radio stations."
"Oh. Well doesn't it have to connect to the station?"
"I see the source of your confusion now. You've become accustomed to that long-ass wire that connects from your car radio to whatever station you're listening to, but this works differently. It's wireless."
"Smart-ass," she's laughing in spite of herself. "Yeah, I'll go check it out."
She was gone about 20 minutes and returned to inform me that it gets fuzzy and unlistenable about four houses in every direction, but sounds nice and clear within three.
"Is this that thing you said we could go to jail over?"
"Yeah, we'll be doing hard time in a Federal prison soon, but maybe not tonight."
Some may be tempted to omit some of these steps, but I don't recommend that because I know this method works.
