I won't say there is an issue that necessarily needs addressing. If you
aren't having any problems then you aren't having any problems. But ground
wires and bonding wires should not normally carry any current, and
connecting BOTH ends of a ground or bonding wire in parallel with a current
carrying conductor causes the ground or bonding wire to also become a
current carrying conductor.
Is your radio chassis ground connected to V-? If ground and V- are
connected at the power supply, then they really should be isolated at the
radio.
