You may consider contacting Get Support at Motorola Solutions or a Ham Radio interest group online. Probably too specific for FixYa.

Here is a link to the user guide: http://www.motorola.com/staticfiles/Business/Products/Two-Way%20Radios%20-%20Unlicensed/_Documents/XTR446/Static%20Files/XTR%20Manual%20EU.pdf?localeId=103

The XTR446 does not have "mute". But what you might be experiencing is a problem with the radios matching one another completely, such as the "interference code" being set differently among the radios. Check your frequency and code to see that they match the other radios exactly. Also, check your radio's mic hole for dust, dirt or debris. This can mute/muffle transmissions.

If this does not solve the problem, you may have a radio in need of repair.

Best regards.

Is the radios PTT button stuck?

Hello,

Try this,

Remove the battery, let the radio sit for about 5 minutes. Replace the battery WITH the mic attatched to the radio and turn the radio on.
Hope this helps, Bill,

Check your antenna connections and coax for loose connections or damage. Also check your hand mic. See if the problem disappears if you turn on the radio without the mic attached. The two most common problems with a mobile radio are antenna and mic problems.

If you feel these are in order, it would be wise to have a tech look at the radio.

your head unit probably does not have a mic you have to get one for the radio not the phone

That is a Maratrac, the squelch is adjustable thru a variable resistor on the audio/squelch board within the chassis. It is labeled R1132 SQUELCH, and is located very close to the locking handle. Some models have a metal bracket that holds the interface board, (thats the only board in the chassis that is mounted vertically), if you remove this bracket you can see R1132 alot easier, but do not need to remove the bracket to adjust R1132. Clockwise tightens the squelch. One catch though, for this adjustment to work, the radio must have been programmed with the unmuting/muting setting in the RSS, set to And/Or. It comes from the factory set for Std/Std. And in my 15+ years in the business, I have seen only one programmer that changes this setting. Me. Good Luck.
