APX APX 8500 Fail 001 Code

[WQOQ867]

I have a APX 8500, being used in a trunking system that goes into "Fail 001" when on a specific site.

The radio will transmit for a second, two at the most, enough for a word or two and the unit ID to be seen and heard by others but then goes to "fail 001".

This is isolated to being on the one site on the system, change sites and its not an issue.

Any ideas?

Needs a trip to a service monitor. Check with the SysAdmin to get a PM done.

Has the radio been put through a service monitor recently?

Fail 001 is the VCO being out of lock. The radio is not happy with a specific frequency used at that site.

Have the radio properly tuned.

You sure the band plan is correct?

Assuming you're referring to the Montana statewide system, which is primarily VHF with a few 700/800 sites in the mix...which specific site is giving you trouble? Is the radio working fine on VHF sites but having issues with 700/800, or vice versa? Details are important, but at the end of the day RadioReference is primarily a hobbyist website, not the best place to seek help with a legitimate subscriber on a statewide public safety system. You need to get professionals involved here...local/state radio shop, system admins, MSI, etc.

THIS! Make sure the bandplan is correct. I fat fingered a VHF entry one time on a statewide system and as soon as it went to a specific tower that used that bandplan, it would FAIL 001 on voice calls. I caught the error and all was well. I did some quick math and my typo was trying to make the radio go in to the 230 MHz range when it tried to calculate the voice channel based off of the incorrect band plan setting I entered.
