Question about Northwestern Bell 99141 2-Way Radio

Open Question

I have a pair of old Bell 2 way, #99140 radios. Only one can transmit the signal to the other, but both are on the same channel. Is there a manual for these, or a way to set both up to broadcast the signal out?

What does Mon mean on a walkie talkie?


"Mon" is short for "Monitor" and is usually a feature that allows you to momentarily break the squelch (signal filter) and hear anything being transmitted on that frequency. That includes static if there's no transmissions. It allows you to listen for a weak signal that can't break the squelch threshold you have set. Some radios allow you to lock it open by pressing and holding the MON button for a few seconds. Turn the feature off my doing the same thing.

Need a service manual need to modify a MR f55 radio to transmit on 161.600 mhz can you help?


Hello,
You want to be able to transmit to the Coast Station on this frequency I assume. The Coast Guard monitors channel 16 at all times. This would be the primary channel in the United States. Your radio is VHF Marine Radio and has a built in frequency range of 156.050 MHz to 163.275 MHz. There is no need for a modification. This is a duplex frequency. What that means is you will transmit on one frequency and receive on another, while on channel 20. You will not need to transmit on 161.600. Turn your radio to channel 20. When you transmit, you will transmit on 157.000. And when the Port responds to you your radio will automatically receive their signal on 161.600. So if you are trying to figure out how to communicate with the port authorities then for that frequency turn your radio to channel 20 and you will be able to communicate with them.

Regards, Tony

FR60 intermittent transmission


Hello snorker,

It could be battery / power issue. Two-way radios draw much more power when transmitting then receiving. If the batteries are weak the radio might work perfectly fine on receive and then cut-out when you depress the Push-To-Talk.

Problem transmitting


Hello jayhawkrx,

Check the Continuous Tone Coded Squelch (CTCSS) settings on all the radios. (Note that some manufacturers refer to this feature as a Privacy Code or Quiet Code. The actual name of the feature may vary.) This feature encodes a low-frequency signal on your radio transmission. This signal is below the range of human hearing but can be detected by other radios. When the CTCSS feature is active your radio will ignore any signal that it receives that does not have the proper tone encoded on it.

In order for these radios to communicate, all of the radios need to be on the same channel and have the same CTCSS code programmed or the CTCSS feature must be disabled.

I suspect that CTCSS is activated on one of your radios but not on the other. This would result in the situation you describe.

Also take note that when using different brands / models of radios to communicate with one another that the CTCSS code numbering scheme may not necessarily be the same from radio to radio. For instance, CTCSS code 4 on the Motorola TalkAbout series actually corresponds to code A on the Motorola Sport models.

Best Regards,

Hey!

My name is Tony DeMil. I have some other 2276s that work well if you're interested!

Make me an offer. Or, do you have a manual? I also have other models. I came across a bunch in a lost and found sale.

Instructions on how to change channels on TECHNIKA MODEL TA-13


Basic Instructions for Technika Model TA-13

On this model there are 7 buttons:
Left to Right these are:

PTT, Push to talk on lh side as screen faces you.
Power/Menu
Scan
Call
Down
Up
Torch Light (on rh side)

Assuming you have used the power button to turn on the radio, the default channel after installing the batteries is 1 or else the last channel to be used.

Press the power/menu button once-briefly, (the current channel will flash for about 10 seconds.) Then use the Up and Down arrows to change channel. Wait for the remaining few seconds and the radio will return to normal operation.

Press the menu button twice, the letter H or L will appear and can be altered by the Up and Down keys to change the power level of the radio. I think this is transmit power which may help you avoid infuriating local taxi companies. Switch back to High power when you're about to go out for the night and need a ride.

Press the menu button three times. This will turn off Squelch control and make a terrible din. Not terribly useful unless you want to pick up a really weak signal (or find out where the taxi driver has taken your neighbour.)

An easy way of finding a channel is to press and hold the Scan button and then the device will rotate through the available channels looking for a signal. When someone transmits, the scan will pause and you can capture it by pressing the PTT button for a second or two. I have found this helpful in pairing my radios with other sets, or picking out channels that work with friend's radios.

Finally, Volume control is really simple, just up and down when not in any other mode.

I had the instructions, which I think included a mention of all available channels I'll scan and post them if ever I find them. hope this part helps though.
