COS constantly keyed on CM108 fob when plugged into PC

Hi,

I made a CM108 and UV82 connection like many others I have made using UV82 points from HamVoip and CM108 connections from allstarsetup.com.

Something weird is happening this time as when I plug the fob into PC, it keeps flashing between keyed and clear in the simple tune menu.

When I monitor COS while fob is plugged out, it is at 0V and when radio RX’s then it is at 1.6V to 1.9V, however, when plugged into the PC, it is constantly at 1.6V and RX has no effect on the value.

For all my other nodes I use usb instead of usbinvert and it works great. This setting has no effect on the new one. The radio keeps flashing its lights when plugged into the PC.

Any guidance on what could be the issue and how to resolve it would be appreciated.

Regards,

Adam

Update: I swapped CM108 fob for another and although it fixed the constant voltage, there is still no rx audio on node. The voltage on COS is acting fine, i.e. 0V at idle and 3.9V at RX. With usbinvert status shows clear but doesnt update to keyed. With usb it shows keyed and doesnt revert to clear.

Thank you so much for the info!!!

For some reason the problem has been resolvd just to push the squelch to 4. At the same time I use CTCSS so it should not be affected? :grinning_face:

Hi!

I guess you meant to type this on your post My Allstarlink node key up every 20 seconds repeatedly?

As my issue seems to be different :sweat_smile:
