I'm expecting a brown truck to pull up today and deliver me a brand
new NRD-545. As you know, Mr. Franklin and about 17 of his friends
have departed this locale, never to return. Due to their absence, I
have a great interest in proper equipment grounding.

Here is my situation. I have two SWL antennae-a 200 foot inverted L,
fed through a transformer which is grounded; and an Alpha Delta sloper
which has it's "down leg" grounded at the same point. Both coaxial
feedlines are fed through a switch with an arc-plug protector, which
is also grounded, but to a different ground rod about 40' from the
first one. FWIW all ground conductors are flat-braid.

My current radio is grounded to the house wiring, which has been
checked and is done properly. I plan to run the 545 from batteries,
though, so this should not be an issue.

Should I tie these grounds together? And then ground the 545 to the
same point? This would result in some rather long ground connections,
but I'm thinking that would protect the radio the most.

Of course, I'm interested in the lowest noise possible, but my main
concern is protecting my new baby.
