If you want to understand the inter-radio interference issues you face, the
potential for damage they may cause, techniques to measure their magnitude,
and measures you can take to minimize them, I suggest you get a copy of
"Managing Interstation Interference" by George Cutsogeorge, W2VJN. It is
a
This has been discussed recently so there may be something in the
reflector archive.
Space loss formula are for far-field situations:
Pn = 32.4 + 20Log(F) + 20Log(d), where Pn is in dBm, F in MHz, d in km
Antennas as close as you have are in the antenna near-field which has

QUESTION 1: The KX3 has been using an inverted V wire antenna. At its
closest point to a vertical antenna for our K3 they are about 30 feet apart.
Is this too close?
Probably. Conductors in the near field of an antenna essentially become

Nr 2Be very careful using 500 watts out on a vertical only 30
feet away to the "v" antenna of your KX3 as you will blow out the front
end on the radio, usually diodes etc. The best thing to do is to
disconnect the antenna of the rig not being used. Voltage can come in

Hello all, we just got back our KX3 after under-warranty repair.
The technician included a message that the parts he replaced were usually
damaged if
1) Connected to an antenna during a thunderstorm (nope, not here)
2) Power over 100 watts on "an adjacent antenna"
