The meaning of a single point star grounding system is badly
misunderstood. Likewise, the difference between grounding and bonding is
badly misunderstood. A connecti
Eric,
In many cases, the problem being dealt with is the currents flowing
through the "grounds" and complicated by what K9YC refers to as the "pin
1 problem" in that the connectors for audio and RF paths are grounded to
the circuit boards, but not to the enclosure (the enclosure *should*

Excellent advice. And there a
Paul,
It is wise to bond the KXPA100 to the station ground to combat noise and
RFI. In fact bonding everything in the station together with heavy wire
or braid can cure many "strange happenings".
Other than that, you are correct that there is no need from a signalling
connection standpoint
I just bought a KXPA100 and I'm not using any "ground" between it and
the KX3. My station is on the second floor and I use a balanced antenna
in my attic so I don't have either a "station ground" beyond the house
wiring's 3rd prong nor do I have an "RF ground." I have no problems and
no RFI eit
Just wondering how important it is to have connect the GND terminals between
the KX3 and the KXPA100 amp. The KXPA100 manual states the station ground
should be connected to the KXPA100 GND thumbscrew. I was just wondering since
there are many cables connected between the two if the additional G
