Many people unknowingly make the mistake about MP3 FM Modulators and mix them up with FM Transmitters. Even though they are very similar they can be very different and give you very different results. We will attempt to help clarify the difference between the FM Modulators and FM Transmitters in this article.
FYI, for the sake of simplicity we will assume that you are going to use this in your car and when we talk about FM Transmitters we are referring to a personal FM Transmitter you can buy off the shelf not a big commercial one or a homemade one.
Mistake #1 Installation Complexity
Most people do not realize that if you go with a FM Modulator instead of a FM Transmitter that you will be required to install it next to the FM Radio. This means you will have to pull out your car's FM Radio and hard wire it into your car's electrical system plus mess with your car's audio system.
This is not only time consuming but you can easily ruin your car's electrical and audio setup as well as potentially get yourself hurt. That is why most hire a professional to install a FM Modulator but that will cost money which could end up being more than the cost of the MP3 Player, Modulator and FM Radio combined.
Mistake #2 Transmitting
The second mistake people make about FM Modulators is they do not realize that the reason it needs to be close to the FM Radio is because it is transmitter the signal from your audio source, which in this case is your MP3 Player, to the car's FM Radio.
And since a FM Modulator typically only goes a few inches or a foot or two are best it needs to be very close to the FM Radio which requires the installation process mentioned above.
Mistake #3 Frequency Options
Third mistake most people do not realize when going with a FM Modulator is the number of frequencies you can select from. Since manufacturers know that you will not be able to change the frequency once it is installed they usually only give you one frequency to pick from or a few at best.
What that means for you is you have to either pick a frequency that is not on the public FM Band of 88.0 to 108.0 such as 87.7 or 87.9 FM for example or you will have to hijack a frequency that is on the public band and hope you do not run into a commercial station trying to broadcast on that frequency as well.
So how do you avoid making those 3 big mistakes?
Very simple if you want to broadcast the audio from your MP3 Player to your car's FM Radio (or any radio for that matter) you will want to buy a GOOD FM Transmitter. I say good because there are so many out there that just flat out stink. Either they don't go very far or the audio quality is just not acceptable. FYI, you can click on the links below to see a good FM Transmitter to consider.
So let's just assume for a moment that you picked a quality FM Transmitter. With it, you can use it not only in your car but also in your home, office, etc. if you wanted to. Plus you can easily power it without having to hard wire it to your car's electrical system. And you can plug in your MP3 Player without dealing with the car's audio systems setup. Finally, if you pick the right kind of good FM Transmitter you can also broadcast your other audio sources like your satellite radio, home stereo, computer and even your TV.
This way you can avoid having to deal with the cost and time of installation and hard wiring as well as possibly screwing up your car's electrical and audio systems. Plus you can transmit further than a modulator and on more frequencies so you won't have to compete with commercial radio stations.

A transmitter is the most vital and one of the most costly pieces of equipment that is required to set up a radio station. Thus a knowledge of the features of a transmitter is a must for any one planning to set up a radio station. The power of a transmitter is measured in watts and it is the most important feature to be looked into when buying a transmitter.
The first thing that you will need to decide is the distance over which you want to be broadcasting. Higher the distance over which you intend to broadcast, more powerful would be the required transmitter.
To give you an indication, a 1 Watt transmitter can broadcast in an approximate radius of 1 to 3 miles coverage. A 5 watt transmitter can broadcast from 4 to 5 miles radius. A 15 watt transmitter can approximately transmit up to 7 miles, A 30 Watt transmitter upto 9 miles radius and a 100 Watt transmitter up to 16 miles radius.
Broadcasting beyond 16 to 17 miles in FM mode is generally not feasible. With this data in hand, you can now easily estimate which transmitter would best suit your plans.
The second question involves deciding whether you should buy it from the local market or export it. My advice here is that if your country has some established transmitter manufacturer, it is mostly practical to be buying it indigenously. This saves considerable expenses in setting up the radio station and it also translates into a better after sales service ion most of the cases.
Besides, you must also try to buy the entire solutions from one vendor rather than buying individual equipments. This way you protect yourself from the burden of handling mutually incompatible equipments of different manufacturers.

Summary
AnyLink is a small device that plugs into the trainer port of a transmitter. It works with a large range of different transmitters, including many of those made by Futaba, JR, Spektrum, and Hitec. Many FM and 2.4GHz transmitters are supported. Adapter cables that work with many of these transmitters are included. Adapter cables for other transmitters need to be purchased separately.
Once plugged in, your transmitter can be used to control any Tactic receiver. Hobbico has also just released about a dozen different small model airplanes that come with these receivers pre-installed. They are called Tx-R ("transmitter ready") airplanes.
Tactic transmitters do not require an AnyLink device to communicate with the Tactic receivers. Also, SLT refers to "secure link technology". It's the specific 2.4GHz signal encoding used by the Tactic systems.
Tactic Brand
From the looks of it, Tactic is to Futaba what Spektrum is to JR. In other words, it's a sister budget brand. Tactic radio transmitters are definitely lower-end than most Spektrum radio systems. Tactic transmitters don't have digital displays and are only available in 4 and 6 channel aircraft versions. All current Spektrum transmitters, except for the DX5e, include digital displays.
The Good
The AnyLink device itself only costs . That's a good deal. A 6 channel Tactic receiver goes for , which is reasonable. The receiver only weighs 8 grams. There's a reasonable variety of airplanes already available with the Tx-R feature. In other words, they come with a Tactic receiver pre-installed.
The Tactic 6 channel transmitter with a 6 channel receiver retails for 0. The 4 channel transmitter/receiver combo is . The Spektrum DX5e, the least expensive radio system in that lineup, retails for 0. The Tactic systems definitely have the advantage as far as price.
The Bad
The Tactic receivers are currently only available in 3 and 6 channel versions. If you need more channels than that, you are out of luck.
The range of the AnyLink is just 1,000 feet. That's good enough for most situations, though I would be real careful with a thermal duration glider or any other model that could get far from you.
The Ugly
The top of the line Hitec Aurora 9 radio system is not supported at all. Neither is the new Spektrum DX18 radio system, though the Hobbico website could just be out of date.
Almost the entire current Spektrum line up of radio systems requires a 0 adapter cable. Ouch! The only exception is the DX6i, which works with an adapter cable included with the AnyLink.
Conclusion
I'm no marketing genius, but I'm having trouble seeing the compelling use case. Buying a receiver separately from an ARF airplane and plugging in the servos into it is pretty easy. Installing the servos correctly is much harder. I guess the hardest part of a receiver installation is plugging in the servos into the right channels. It would seem that a Tx-R airplane's primary appeal is to those relatively new to the hobby.
Somebody just starting out will just buy a Tactic transmitter and a matching Tx-R airplane. Given the convenience, I would probably buy another Tx-R airplane as my second airplane. There is some value there for the end user, at the cost of limiting your airplane choices.
For a current Spektrum transmitter owner to pay +0 = 5 just so that they can use a Tx-R airplane would be nuts. I don't see it happening.
I suppose there might be a market for those owners of older FM transmitters wanting to move up to 2.4GHz that do not want to spend much. Whether is a reasonable price for these cheapskates (I mean, frugal folks) is debatable.
I have a hunch that the AnyLink system was overcome by events before it was released. Not supporting most of the current Spektrum lineup out of the box is going to seriously limit its acceptance.
On a positive note, it does offer reasonable value to those starting out that have purchased a Tactic radio system.

You need a Garmin GPS models comparison if you want to buy the right system for your needs and budget. Although all Garmin products are known for their quality, the prices range from less than 0 to over 0 for a vehicle GPS system. That's a big difference. Not everyone needs the higher end products, either. For many people, the lower priced models will suffice just fine. In this Garmin GPS Models Comparison, we'll take a look at three Gamin nuvi models from the lower, middle, and higher ranges.
Garmin GPS Models Comparison: Budget Models
Garmin has several budget models around 0. Let's take the nuvi 205W, for instance. Not only does the nuvi 205W have the wider screen, but it's got a host of improvements over Garmin's nuvi 200 series as well. For instance, Garmin now has a predictive technology, which results in the device recognizing where it is faster and locking into the satellites faster. What this basically means is the device will start working faster once you turn it on.
Garmin GPS Models Comparison: Mid-Range Models
Garmin's nuvi 755T currently sells for just under 0. It has a ton of great features, like a wide screen, text-to-speech (actually says the names of the streets you're to turn on), and has FM transmission capability. One thing that I really like are the "where am I", "where is my car" features. With one tap on the screen you can activate this feature, which lets you see where you are in relationship to the world around you. Also, when it's removed from the mount on the car, it marks that position. This lets it remember where the car was so that it can show you later on. If you've ever lost your car in a large parking garage, I'm sure you can see the benefits of this.
Garmin GPS Models Comparison: High-End Models
No Garmin GPS Models Comparison would be complete without mentioning the Garmin nuvi 1690 4.3-inch Bluetooth navigator with nuLink. Of course, it's got all the bells and whistles. And it should, considering right now it's going to set you back about 0. But in addition, it's got nuLink, which gives you real time information about wherever you are with a subscription.
So, we've covered three representative models in this Garmin GPS models comparison.
