Okay…
In viewing the way a transmitter works, you must realize that some form of frequency determining circuit must be used to place the RF Signal at your desired spot in the frequency spectrum. The spectrum (or range of possible frequencies) will depend upon the design of your particular fadio set. Some work on a range of frequencies from 0.5 to 1.75 Megahertz (the AM Broadcast Band), some work on a range
of frequencies from 1.6 Megahertz to 30.0 Megahertz (the MF and HF Bands), and others work on:
30.0 – 54.0 Megahertz (Low Band VHF)
54.0 – 108.0 Megahertz (Low Channel Television,
& FM Broadcast Band 88.0 – 108 Mhz)
108 – 135 Megahertz (AM Aircraft Band)
etc., etc., etc.
You need to position your transmitted signal somewhere in
the appropriate range of frequencies where people will expect to tune in and receive what you are sending. The device that does that frequency setting is called an oscillator.
Many types of oscillators exist, fixed frequency oscillators,
variable frequency oscillators, synthesized oscillators, etc.
All of them do one thing…they output an RF Signal on one particular frequency. If you amplified that signal and sent it through a tuner out to an antena it would be a constant carrier signal.
Now The object of transmitting a signal is normally to convey some kind of information to a distant point where it will be received and the information retrieved by a listener who has an appropriate receiver. A constant carrier signal can only signal "the ON Condition." It just sits there and goes Blahhhhhhhhhhhhhhhhhhhh… or Beeeeeeeeeeeeeeee…
Using a keyer, you could interrupt the carrier signal and send a prearranged kind of code like in Morse Code using long and short key down pulses from the transmitter. At the far end someone who knows what particular code you are sending could decypher your transmission and hand the information to the designated recipient. Voila, working code transmitter and receiver set up.
However, not everyone knows the code, and if you want the transmission to be heard and understood by the masses of people out there in radio land, you probably ought to send your transmission using Voice.
To do that, you use some form of microphone, and audio amplifier to influence the current going into the final RF Amplifier in the transmitter. As you speak into the mike, the audio amplifier's power is added and subtracted to the normal current flow of the RF AMplifier and this results in added energy on the carrier frequency which is called side bands. If you speak, the side bands show an energy burst higher and lower than the center frequency (which is the carrier). Depending upon the exact method (circuitry) of adding the audio to the carrier transmitter there may or may not be additional fluctuations in power of the actual carrier signal also as you speak into the mike.
At the distant receiving location, a special Demodulator circuit strips the audio off of the incoming carrier signal and sends it to an amplifier and speaker for people to listen to audibly. There are many types of Demodulators that perform this function.
As it happens, the information content in the Upper Side Band is the same as the information contained in the Lower Side Band. So, in the interests of using as little frequency spectrum as possible, many modern transmitters use special circuitry to suppress one or the other of the two sidebands, and even the carrier. The result is that all of the power that is generated gets dumped onto the remaining side band and a very potent and narrow transmitted signal results. This is called Single Sideband. Many, many more of those signals can be packed into a given chunk of frequency bandwidth than signals with the standard carrier and two side bands.
Hope this helped you understand Side Bands better…

A stanard bike you ride sitting more up right on. A sport bike you are more leaning forward. A sv650 if you can stand flat footed should be a good bike and be happy with it for years. Look at the fz6 also.

I recently spent many hours driving and riding in an Audi A4 S-Line in Europe on the Autobahn and in small villages. Very nice, very comfortable, great handling and perfectly poised up to 100mph. Not saying I’d pick it if price were no object but was definitely impressed with Audi’s execution of a (near?) luxury sedan.

There comes a time in every bicyclist’s life when you come to realize “I really don’t want to pedal up that hill.” For those riding a Sanyo Eneloop, they don’t have to. The series of bikes has been getting more advanced over the years, and the new SPL models are the smartest yet. Whereas previous editions could only regeneratively charge themselves on downhills or when the brakes were applied, this new series can juice up while the rider is pedaling along on the flats. This presumably increases the rolling resistance somewhat but the new “Eco Charge Mode” is said to boost range by 53 percent. More importantly, a new chrome basket shows that this ride means business. It won’t come cheap, though, shipping to Japanese pedalers on April 21 for ¥157,290, or about $1,800. For that kind of money we’ll stick with our fleet of Huffy 10-speeds.

Roof protester bids to go in front door:
Motorized Bicycle GT2 bicycle retailers: anyone know of any more GT2 bicycle retailers? lowest price found so far …
ahha, you probably shouldn't do that. the cheese will melt everywhere and it'll be hard to get it out. i'd use a pan.
Sometimes, when I’m too tired to bike home from work, I jump in a cab. It’s still cheaper than driving every day.
RT Money can't buy happiness… but somehow, its more comfortable to cry in a BMW than on a bicycle

BA haven't confirmed what's happening on the 28th.If they cancel will they put us on another flight with another carrier?
That was so exciting that Sanyo also revealed that it’s the world’s first ‘solar parking lot’. Awesome! And the park is powered by sets of solar panels on the roof of the lot. Placed your bikes there and take it after you are going shopping, working and doing certain activity.

If you've got the money, the desire to continue doing triathlons, and the determination to be as competitive as possible, then there's no reason not to purchase a TT bike at the highest level your wallet can take.
But if your current road bike is up to it, how necessary is it to lay out the money for a TT bike that will perhaps only shave a few minutes from your total event time? Every triathlete has their strongest area…and their weakest area. If you're not a particularly strong runner or swimmer, and you count on the bike segment to get pick up some time, then you want to be on a bike that's up to the task. Of course, a weaker cyclist might count on the best bike to help them on his/her worst segment.
Again, you're probably only talking minutes here. How important those minutes are and how much disposable income you have should be the factors that determine your decision. Otherwise, keep training and invest in a coach.
Sherpak Kanga Hurricane 11 Cartop Storage (Sports)
Anyone have a stationary bike they would part with? I need something new to remind myself how lazy I could be.
Since you want to raise the roof , it fit swell the typical installation method for the corrugated roofing.( perimeter plate & rafters)
Normal framing for the roof structure & special wood "spacers' which are shaped to fit the corrugations of the roofing material get nailed across the rafters hold everything in place & fill gaps.
There are gasketed screws & nails which fix the roofing to the spacers (usually in the "valleys")
Will have to pre drill the plastic at fixing points.
