Question 1

How to switch from stored frequency B1 to stored frequency B2 on the YAESU VX-150 radio?

Accepted Answer

To switch from stored frequency B1 to another stored frequency B2 on your YAESU VX-150 radio, follow these steps:

1. Turn on the radio

Make sure your YAESU VX-150 is turned on.

2. Select memory mode

Press the MR (Memory Recall) button to access the memory mode where frequencies B1, B2, etc., are stored.

3. Navigate between memories

Use the channel selection button (often a knob or arrow keys) to scroll through the stored channels.
Turn or press until you reach the memory corresponding to frequency B2.

4. Confirmation

The radio will display the frequency of the selected memory. You are now on frequency B2 and ready to transmit or receive.

Tip

If frequency B2 is not yet stored, you will need to program it into a free memory slot before you can access it using this procedure.

Question 2

Why am I receiving on all channels with the YAESU VX-150 radio?

Accepted Answer

If you find that your YAESU VX-150 radio is receiving signals on all channels, it means that the receiver is functioning correctly and picking up available transmissions on different frequencies. Here are some explanations and points to consider:

1. Receiver operation

The receiver of the VX-150 is designed to capture signals within the frequency range for which it is intended. Receiving on multiple channels indicates that the device is capable of detecting transmissions emitted on these frequencies.

2. Nature of channels and frequencies

The channels programmed into the radio correspond to different frequencies. If transmissions are active on these frequencies, you will hear signals. This does not necessarily mean that you can transmit on all these channels, but simply that reception is possible.

3. Checking settings

Reception mode: Ensure that you are in the appropriate mode (e.g., VFO or memory) to listen to the desired channels.
Filtering and squelch: The squelch setting can influence the reception of weak or noisy signals.

4. Transmission restrictions

Note that receiving on a channel does not guarantee that you can transmit on it. Some frequencies may be restricted or require a specific license.

In summary, receiving on all channels is normal if signals are present on these frequencies. This shows that your radio is working well in receive mode.

Question 3

Why does my YAESU VX-150 walkie-talkie only transmit on channels from 144.000 to 146.000 MHz and display an error code on other channels?

Accepted Answer

The YAESU VX-150 is designed to operate primarily in the 144 to 146 MHz band, which corresponds to the VHF amateur radio band. If you attempt to transmit outside of this range, it is normal for the device to display an error code to prevent you from transmitting on unauthorized or unsupported frequencies.

Possible causes and solutions:

Built-in frequency restriction: The VX-150 is programmed to limit transmission to the authorized frequencies in the VHF amateur band. Attempting to transmit outside of this range generates an error code.
Operating mode: Check that the radio is in VFO (variable frequency) mode and not in memory mode. In memory mode, only programmed frequencies are accessible.
Radio settings: If you have modified the settings or loaded custom memories, a configuration error may limit the usable frequencies.
Reset: To eliminate a configuration issue, you can reset the device to factory settings. This will restore the default frequency ranges.
Compliance with regulations: Ensure that you only transmit on frequencies authorized by your amateur radio license and local regulations.

In summary, the behavior you are observing is normal if you are trying to transmit outside the 144-146 MHz band. To use other frequencies, you would need a device compatible with those bands and to comply with the applicable rules.
