Yaesu ft-857 squelch problem


Your RF gain control needs to be turned all the way up to be able to receive signals and if you are on one of the HF bands like 40 meters or any HF band the squelch control needs to be all the way off! You do not use squelch on HF! When on VHF or UHF then you would rotate the squelch control just to the point that the background noise stops and go no further. Higher squelch settings will only block weak signals and your radio will be deaf! Squelch control rotated just to the point the background noise stops! NO SQUELCH ON HF. Turn the squelch all the way off on HF!

Mt mag one bpr40 uhf 450/470 will receive but will not transmit. green light is on all the time


It probably has "busy channel inhibit" turned on in the menus, and the squelch is open, thus making it think there is a signal on the channel you're trying to use.

How can i stop the squelch ive tryed turning the sqcuelch doesnt help


Plug the AC adapter into the back of the scanner and into a wall electrical outlet. Screw the antenna into the receptacle on the back of the scanner (extend the antenna to full length for best reception).

  • 2 Set the squelch level to allow signals to be heard by turning the squelch knob counterclockwise. Rotate the volume knob clockwise until you hear static. Slowly turn the squelch knob clockwise until the static noise disappears.
  • 3 Start programming frequencies into the scanner by pressing the "Manual" button.
  • 4 Press the up arrow or down arrow key until the channel you wish to program is visible on the display.
  • 5 Use the numbers on the keypad to enter the frequency for the local transmitter you wish to receive.
  • 6 Press the "E" key to complete the process of entering the frequency.
  • 7 Repeat steps 3 through 6 for each additional frequency you wish to monitor.
  • 8 Press the "Scan" key to start the scanning process. The scanner stops on a channel when it detects a signal strong enough to hear over the squelch setting. Two seconds after the signal stops, the scanning process resumes.

    All of a sudden my patio heater will not stay lit.


    Describe the pilot. Is it a strong blue flame or lazy yellow? Is the thermocouple getting red hot by the pilot flame? I'm wondering if the pilot is impinging enough on the thermocouple to keep it lit. It may be dirty, so try blowing out the pilot orifice with a can of compressed air and see if that helps. Also make sure the thermocouple tip is not burn't. If you feel the tip and it feels jagged, then replace it. Hope that helps. Douglas

    I don't have the manual for my Uniden Bearcat BC 855 scanner.


    You can download/print the complete manual for your scanner by following the link below. It's a free download, and it provides detailed programming instructions. If you're programming a channel that is "empty" (showing 000.0000) just enter your frequency. Empty channels automatically show LOCKOUT but it clears with programming. The squelch setting will vary according to the strength of the signals you receive. Once you start scanning, turn the squelch down until scanning stops and you hear a hissing sound, then turn the control up slowly until scanning resumes.

    Hi any one know any cb repairs near norwich thanks


    Dunno about any shops near where you live. There are a few good places online you can send the radio too.

    Does this radio have an RF GAIN? if it does this should be all the way up. Also, bring down the squelch.

    The RF GAIN on a cb radio is how sensitive your receive is. the more up it is, the further you can hear.

    the squelch is used to cut off noise. The higher the squelch is, the strong a signal needs to be to hear it, so you will only hear people close.

    Check the squelch on your radio thats not recieving. If there is a monitor button ( when pushed you will hear static) try pushing it.. then get someone to call you so you can check if you can hear them. On these radios you have 2 types of squelch....1 is called carrier squelch.... it basically opens when there is a strong enough signal. This lets you only hear strong signals and "squelch out" the distant ones and background static. The2nd. is "tone squelch" ... with your radio they are often called privacy tones. If you have 2 radios set with the same privacy tones you will only be able to hear each other... only radios that are transmitting with that privacy tone will be heard on your radio. Its a high frequency tone that can't be hear by the human ear that gets "embeded" with the transmitting signal. The recieving radio hears it and opens the squelch. So... if the radio thats rxing (recieving)your signal has its squelch set for just carrier squelch it will hear any signal thats strong enough to break the squech open.... basicaly any radio within a certain range. But if your radio (one with problem) has its squelch set for privacy tones you will not hear any other radios except the ones set with the same privacy tone.... the squelch will not open until it gets a tx signal with the right tone.... so if the txing (transmitting) radio is not using tone squelch but is using carrier squelch.... and the rxing radio is set for tone squelch... the rxing radio will not hear it. With tone (privacy tones/codes) squelch you need a tone to open the squelch and then the audio can be heard... with carrier squelch the squelch will open if ANY radio is within a certain range. Check the squelch setting on the problem radio... it could have a privacy tone set. Try pushing in the monitor button so you can hear static ( you want to hear everything including static) on both radios... tx on one radio at a time and listen if it can be heard on the other with the monitor button pushed. If you can't hear any audio when the broken one is transmitting then it COULD be the mic.... if you can hear both radios with the monitor button activated than the radios are txing and have tx audio and are working... if thats the case its the privacy tones that are the problem. Take care
