||A special cassette with a wire
sticking out of it to magnetically couple the audio output from a
device through the head of the cassette player.
||Cheap and readily available.
||Not the best audio
quality. Head to head contact can cause wear or damage to the
drive head. Cassette transport has to run all the time (belts
clutches, etc). Wire and adapter must be inserted and
stored. Cassette door can damage adapter wire. Lengthy wire
must be kept under control. Stereo seperation can be poor.
Tone equalization is usually way off.
||Either built in to a device as a
transmitter or a seperate transmitting device.
||Convenient if power source is
available or built in to device. Reasonable to use in remote
||Often not good audio
quality. Suffers competing interference from nearby stations on
same or near frequencies. Transmitter and radio must be tuned to
same frequency. Every time competing signals occur, both devices
must be retuned to a new frequency. Sometimes more than once in
||Wired FM Modulator
||A dedicated FM modulator that
get wired to the bike and who's signal is injected directly into the
||Most have good quality
sound. Does not suffer from surrounding interference. Has
good channel seperation. Does not need to be removed when
ride is over.
||More expensive than the above
options. Must be installed once. Not quite as good audio
quality as radio modification but close.
Not available in every corner store.
Some of these devices are much worse quality sound than others.
||An internal electrical
modification of the inside of the radio to tap into the system between
the amp and preamp to add an extra line-in jack.
||Best quality sound if ground
loops and incompatabilities between the injecting device and the radio
are resolved. Can be done cheaply if the parts are obtainable.
||Requires opening and modifiying
the radio. Some electronic and soldering skills are
Potential damage to the radio is possible.
Some method of getting a switch and external jack outside the radio is necessary and must be kept waterproof. Radio must be removed from the bike to do the work. Since there is no isolation between the radio circuits and the added device, the radio is more vulnerable to external electrical damage than any of the other methods.
