Can you get into the second radio tower on Pokemon Crystal?
if your talking about the one in kanto you cant they wont let you becauseof secutiry.
Check the fuse, then check power at the fuse, if the fuse is blown or there is no power this could be your problem. If the fuse is good and theres power, you will need a wireing diagram, to check for possible short to ground. ABS light could be ABS relay (under hood).

Why can radio waves travel through space but sound waves cant?
Sound waves are longitudinal waves that need a medium to propagate. This can be air,water or solids. Sound waves work like a truck hitting a line of cars. The wave travels through the line from back to front but would not if there were no cars.
Radio waves, like light are electromagnetic waves and don't require a medium to radiate. That is why we see Sunlight but do not hear the constant roar of the Sun's fusion activity.
no as long as you have a scanner to hook up the antenna to analog scanner there about 100 dollars digital ones are 400 the scanners have the speaker on them
Why the automatic frequency control function is usually not necessary in today's FM receivers?
AFC was used to provide an electronic means to stabilize the frequency of a circuit. Older receivers and transmitters used a tank circuit, made of an inductor and capacitor to select frequency. Since both the inductor and capacitor are physical objects, their sizes and properties vary with temperature, humidity, age and other factors. Also to be able to tune the frequency, at least one of them had to be deliberately made to be mechanically alterable to change it's electrical properties. These factors caused the frequency to slowly drift over time. Also, the tuning was usually accomplished in a continuously variable way, so it was difficult to confirm an exact tuning to the station which could lead to loss of sensitivity or distortion of the signal. AFC used electronic feedback to fine tune the tank circuit by a (usually) electrically tuned component.
Modern radio equipment tends to use a quartz crystal oscillator of a fixed frequency as a reference. Quartz crystals can easily be made stable in frequency to 50 parts per million. This is sufficiently accurate to not need to compare it with the frequency of the incoming signal, itself derived from a stable crystal source. The radio is usually tuned by a frequency synthesizer controlled by the crystal.
Both AFC and the frequency synthesizer method use an electrically tuned variable frequency oscillator to tune the radio. The difference is that AFC used characteristics of the received signal to measure and correct the mistuning, while frequency synthesizers compare the tuning with crystal reference. AFC cannot find the frequency you desire to tune, it only fine tunes it once you select it. The frequency synthesizer accurately tunes the radio to whatever frequency you ask it.
Where can one purchase handheld radios?
Once you have your Amateur License, you can buy a ham radio online, you can go to a local hamvention where vendors like icom and kenwood will be selling radios, you could go to a local radio club, I'm sure they'd be happy to sell you one of their old radios at a great price, or point you in the dirrection of a local ham shop.
