[Elecraft] 12 volt battery

[Dale Putnam]

HI Clint,   Wouldn't that be in parallel with the station ground? IF the radio puts the battery  negative ground... if not.. then it would provide another path for noise to enter the radio... and.. it would also provide another path.. not desired - for lightning to follow. I'd be real hesitant to do that, unless someone else can justify it.  The station needs a ground.. yes. The rf needs a ground.. yes... battery.. no
In the field or in an RV.. same thing.. the station needs an rf ground.. and a dc ground.. as in one stake.. if you are staying put long enough.. or ground to the vehicle. But not necessarily reground the vehicle battery.. that could be a bad thing... that, under certain failures cause an excessive amount of current through the radio ground... and that would not be a good thing at all. 


Have a great day,
