MS Error when scanning Yaesu Radios with Banks

Last Updated: 07/25/2013
In a recent report from a customer, they stated when trying to scan a certain bank in their VX-8G, the radio would display "MS Error". Scanning appeared to work fine in Bank 2, but not Bank 1.

After further testing with the radio along with reviewing the file, we discovered that if the channels are set to "Skip", they will remain skipped in Memory Bank Scanning as well as Memory Scan. If they are all set to skip, the error occurs. Once we set them to "Off", the channels would scan just fine.

This is also NOT specific to any certain bank. The results are the same if all the channels are set to skip in Bank 2.

Without the RT Systems programmer, we would not have been able to view the settings of all the memory channels at once to spot the pattern. Attempting to identify the cause of this problem from the face of the radio would have been difficult, if not impossible.

Other Yaesu handhelds handle this issue differently. So it appears the "MS Error" is specific to the VX-8G/R series of radios.

For more information on Bank Scanning, you can refer to page 61 of the owners manual for the VX-8G and page 67 of the owners manual for the VX-8R.
