Off frequency when I contact someone on side band they tell me i sound high pitch off frequency

FM frequency assignment is not a simple matter. See https://en.wikipedia.org/wiki/FM_broadcasting_in_the_United_States: "In the United States, frequency-modulated broadcasting stations operate in a frequency band extending from 87.8 MHz to 108.0 MHz," But you might want to read the remainder of this Wikipedia article; it explains how this frequency is almost always used by TV stations (which use the FM band for their audio). Or, you may want to Google "87.7 FM" for more insight; that search turned up a station in Boston and one in Chicago supposedly operating on the 87.7 frequency. But your best bet would be to contact that station and ask them how to receive their broadcasts; I'm sure this wouldn't be the first time someone has had this problem.

There is a metal tab on some pads that contacts the rotor to make hideous noises telling the driver they need to replace the brake pads. It's in your owner's manual.

Basically a crossover filters high and low frequency sound into separate bands and then only allows that band of frequency to reach the speaker! Uses are for feeding a sub woofer with low frequency sound and a tweeter with high frequency sound!

• Hi, I can help.

• I have uploaded a pic of the Cobra 200 and labeled each knob/switch with letters to reference.

1. A) Noise blanker - When this switch is pushed the high pitched noises are canceled leaving a more natural sounding receive. Some like it some don't.
2. B) High Power - This button adjusts the power output of your radio. Inside the radio the pots are adjusted for a low power setting and a high power setting.
3. C) Roger Beep - This is a beep heard by the person you are chatting with at the end of your transmission.
4. D) The 10+ KHz - This button when pushed jumps the frequency up 10 Kilohertz to help you better navigate frequencies.
5. E) This is where you adjust how you are going to modulate. CW is for continuous wave or Morse Code. Unless you have a key don't worry about this setting. FM is for Frequency Modulation AKA the HAM bands. AM is for Amplitude Modulation. USB and LSB are for Upper Side Band and Lower Side Band respectively.
6. F) is the band adjustment - Each band (A, B, C, D is a set of frequencies.
7. G) is a dimmer and the SWR calibrate. To use the dimmer push the dim button in a rapid motion. To use the SWR calibrate side press and hold the dim/calibrate button and using the SWR knob on the right side of the radio (L).
8. H) SWR/, S/RF - If this button is in the out position then your meter will swing as usual. Push the button in to measure SWR.
9. I) is the volume and squelch. Volume is what is adjusted to how loud you want your speaker. Squelch you adjust to take out the unnecessary white noise.
10. J) Mic Gain and RF gain - Mic Gain is how much gain you want to your mic. RF gain is how much of the receive you want to pick up.
11. K) Is the fine and course adjustment that you clarify your frequencies with.
12. L) You adjust the echo and the SWR with.
13. M) is the channel selector.

• Hope this helps and thank you for using FixYa.

If what we are talking about here an old model of monitor that has a bulky back, the high pitched frequency is caused by other electronic devices such as your speakers.

- Relocate your speakers away from the monitor
- do a factory reset on all settings on the monitor or if possible, do a degauss.

If the whine changes pitch with engine RPM it could be a serious problem with the alternator. Possibly the voltage regulator, or a shorted diode in the alternator causing high frequency AC to be fed into the harness.

you need to install a radio suppressor, that will eliminate the noises,

you can buy them on ebay, but google "radio suppressor" and find out why it's happening,

if it's an older car you connect 1 to your coil terminals, but i would go for an inline version first (you coonect to radio power wire).

Hope you listen to clear tunes soon :)

This sounds like a difference in the sampling frequency.  Music recorded at 48Khz must be played back at that frequency or there will be a significant difference in speed and pitch during playback at 44.1Khz. I first noticed this when it occurred to me when recording on digital audio tape.  Ipods and minidiscs and mp3 recorders can record at high sampling frequencies like 48K.  Cds are all recorded at the standard 44.1K sampling frequency.   Check the source of your recordings and it should follow a pattern that leads to your current results.       I do not have enough information  on how your music was transferred to tell you more at this time, but I am very confident that differences in sampling frequencies of your source material are causing the pitch differences you are hearing.   Without knowing exactly the sampling frequencies of each piece of equipment you used to record these songs it will be next to impossible to give you a very specific solution, so I hope the info. I have shared helps you to figure it out.  Best regards and good luck!   Michael Mittelsdorf

If they are wearing down, they may squeak, and some brakes have a metallic part that will come in contact with the rotor when the wear gets to a certian point making an awful squeaking sound telling you that mabe you should change 'em soon, eh

Is your speaker making this high pitched sound or is it something else. If it's "something else" then there is no problem to worry about. It's just an audible frequency given off from the touch screen.
