Q: How to buy the antenna separately?

Q: How to turn the transmission power down?
A: Turn the unit on with the antenna fully extended. After the unit is on and transmitting, push the power button one more time quick and let go. The symbol of an antenna in the top left corner should be blinking. If the antenna symbol is not blinking hit the power button till it does. Now hit the down button, this will bring the unit down to 5 watts. Never lower the antenna from its full length an this will damage the transmitter. The difference between 5 and 15 watts will be about half the range.
Q: Why the transmitter seems to constantly buzz?
A: If so, please do as the following instructions:
Make sure your audio input is plugged into the "audio" port and not the "mike" port.
Make sure your antenna is the correct length
Check that your antenna is not touching anything
If your accessory cord and your power cord to your communication media (iPod, computer, etc) are entangled or touching that will cause interference, if your media is to close to your antenna same.
Choose a broadcast frequency that is clear, and that means all the time, sometimes the weather can bring a station in that is not normally a problem, that will cause hiss as well.
Sometimes solar activity causes interference and problems, there is nothing much you can do for that except wait it out with this equipment, it is usually a matter of a day or so
Q: Can I change the transmitting channel with the software on a PC?
A: This unit has an adjustable FM selector just like your radio.. you can broadcast on any frequency on the FM dial from 87. to 107. PC not needed.
