A friend and I both had our KX2 transceivers and some resonant end fed antennas. He was on 15m and I was on 20m. Our antennas were placed about 30-40 feet apart, as slopers with the radiating ends up 30+ feet in the air using Jack-kite poles. The plane of the antenna's slope were perpendicular to each other.
We were both on 10w SSB.

Every time one of us keyed up, the other person's KX2 would experience a nasty noise from the signal. Pre-amp was off, as was attenuator. My question is this: Would the use of some bandpass filters have helped us? This is a situation we are trying to resolve before operating QRP in a similar park for a QSO party.

If more distance between the antennas would have helped, what is the proper way to determine the needed separation?

I read the other day about someone in a car using 3 or 4 Elecraft radios with antennas on the roof, so I imagine there has to be a way.

Thanks,
