[TenTec] Station power supply??

[Cecil]

One only has to spend 15 minutes in the Motorola R56 standard for lightning and surge protection grounding to understand the shortcomings of the NEC in properly protecting radio systems installations from those risks.  The R56 is the industry standard for such installations and is an excellent model for how to properly protect an amateur radio station installation from those risks.  

The NEC has electrical safety grounding covered and the v- grounding issue appears philosophical and won't be settled here.  

I will say that many DC powered transceivers have the V- tied to chassis ground and if you follow the manufacturers instructions (and accepted practice) and tie the transceiver ground lug to an outside lightning/surge protection grounding system...and that grounding system is bonded to the building electrical safety ground as required by the NEC, the V- is effectively tied to the "green wire" at the electrical panel.  

Just checked two Omni VI's and my Orion II and two Astron switchers...all have V- tied to chassis ground.  

I have no opinion at this point as to whether that is proper or not but I don't see many modifying their gear to change that...

I'm done...
