FM Radio Frequencies

[3aBuD]

Hi all.. I am new here .. and hope that you might help me out..

is it possible for a 2002 Tahoe (imported from the US).. to receive
even FM frequencies?

The local governmental radio stations are odd
Examples: (Super Station 99.7), (Classic Jazz 92.5), so there is no problem..

the problem is that lately new private stations came up with even frequencies..
Example: (Marina FM 88.8), (Mix FM 98.4)..

when tuning the channel - for Marina FM - I get either 88.7 or 88.9, since the interval is attenuated at 200khz, is there a way to switch\change the interval to 100khz??

Thanks in advance for your help
and have a pleasant weekend.

welcome to the forum.

You shouldnt be listening to anything but government stations. What do you think this is, a free country?


Seriously though, I dont think its possible to modify this feature of the stock radio. Do you have the option of installing a new head unit, or not really?

That's unusual, because all the major stations in the Richmond area are odd as well. 92.1, 94.5, 101.1, 102.1, 103.7, 98.1 and 106.5.

I googled it, and if you lived in Europe, you'd have a radio that would work, but in the U.S. you're out of luck. Not sure why a private station would broadcast on an even channel if no one can listen to it.

In short, the answer is "no".

For the long answer: In United States, there are 201 channels, numbered from 200 (87.9 MHz) to 300 (107.9 MHz) in increments of 200 kHz. In the United States, the twenty channels with center frequencies of 88.1–91.9 MHz (channels 201–220) constitute the reserved band, exclusively for non-commercial and educational (NCE) stations. All the other channels, with center frequencies 92.1–107.9 MHz (and 87.9 MHz, where used) may be used by both commercial and non-commercial stations. Normally, each channel is 200 kHz (0.2 MHz) wide, and can pass audio and subcarrier frequencies up to 100 kHz. Frequency deviation is typically limited to 150 kHz total (±75 kHz) in order to prevent interference to adjacent channels on the band. The your radio is set to jump at frequency intervals of .1, .3, .5, .7, and .9 based on the US band plan for where it was design to be operated. I have no doubt that it's capable of tuning at other frequency intervals, but it's something that couldn't be done by the user.
