Re: mt1000 lock up
I think there is a problem with the Synthetizer, you will need quilyfied service.
This could be caused when you change frequency, the Synth, can not be able to "produce" the desired freq. caused for a problem in this area, this causes to the radios get PLL UNLOCKED and this could be the way that the radio give an alert to the user.

You have to be in "VFO" mode. Your best bet on that extremely difficult to use radio, is to get "chirp" and the proper cable and program it via a computer. If you search on-line for "baofeng programming" you may find an alternate set of instructions. Your absolute best bet: throw that PoS away and get a Yaesu FT-60.
With the radio turned OFF, hold in the PTT and the MON, while turning the radio on. Continue to hold the PTT and MON until the radio stops making noise. You are then in programming mode and can use the menu button to walk through the stages of programming. Use the PTT to change the settings, and the MENU to lock it in.
The instructions for getting into programming mode are on page 18. A synopsis is this:
1) Hold in the PTT button and the MON button while turning on the radio. Continue to hold them in until the radio is no longer making noise.
2) Press the Menu button one time. This is your Freq. Use the plus or minus button to change the freq. Press the menu button to lock in your selection.
3) The next number is your Code. Use the same method to select your code and lock it in.
4) Continue through the menu, making your selections according to the user guide. When you are at the end of the programming cycle the radio will emit a different chirp. When this occurs, shut of the radio and turn it back on normally. You are done programming.
To program the radio:
1) Hold in the MON button and the PTT while turning the radio on, continue to hold the buttons in until the radio quits making noise.
2) Press the MENU button one time, this will take you to your FREQ. After selecting your FREQ
3) Press the MENU button again, select your CODE, press the menu button again
4) You will begin to walk through the other settings possible for the radio at each press of the menu button. Here are what you will see in no particular order:
4a) Hi Lo: this is a reference to narrow or wide band channel spacing. If you are in the US you should choose Lo as narrowband channel spacing is the newer FCC rules.
4b) A circle with a slash through it: This is your scramble feature. If you choose zero you have no scrambling.
4c) CH: This is where you tell your radio how many channels to have.
4d) Lock: Choose Y or N. This might be what you are referencing in your question. To unlock choose N for No.
4e) A face with wavy lines in front: This is mic gain. The normal setting is 2. However, if you have a soft or gruff voice you might want to choose 1 or 3 to compensate for the distortion heard on the other end.
4f) CA: This is call alert, which will cause a ring before you speak to alert the other radios users they have a call.
On each of these stops through the menu make your selection by using the + or - buttons, followed by pressing the menu button to lock in your new setting. ALL of your radios much match on all settings to work together correctly.
When you get to the end of the menu selections you will hear a different chirp. This will signal you are done. You can then shut off the radio and turn it back on normally to use it.
Each channel should accomodate upto 25 workers so if you program your radio for 4 channels, you will have enough radio workspace for 100 people. Typically most users do not need this much space, so it is advisable to keep your number of channels to a minimum, using only the ones necessary. It never hurts to have a second frequency just incase you run into traffic on your first one.
On a Motorola AXU Series (including the 4100): 1. To unlock, press the “D” button for about a second or until the circle is gone. The circle with the line thru is the keyboard lock indicator; 2. To change channel, you need to press either the arrow left or right in Normal Mode; 3. To change PL (assigned to a channel), don’t think this can be done by the user 4. To change Ch. 1 from 464.500 MHz (PL-67.0) to 463.525 (PL-136.5), don’t think this can also be done by the user.
Even the built-in Programming Mode Parameters do not have this option to change assigned frequencies and PLs. An external programming software using a PC may or may not allow this.
These radios came pre-loaded with its channels assigned with specific frequencies/PLs. As used in a Motorola AXU411, they are:
Not sure what you want.....VHF band ius approximatly 130mhz to 175 mhz..... in that VHF band there is a commercial VHF band aprox. 155 mhz to 175...... the amateur radio vhf band is aprox. 135 to 150mhz.
With amateur radio, any freq in that range can be used...... with commercial radio the FCC cangive a company any freq. in that range also.
If you are looking for FRS/GMRS frequencies they are UHF freqs not VHF.
So I'm not sure exactly what you want......sounds like you might want to program in FRS freqs into an Icom amateur radio. If thats the case you will need an Icom that will do UHF freqs.
