[Elecraft] OT - operating QRP at same park

[Detrick Merz]

I was there with K4VD for this. Same thing happened last year at Field Day
too, although the antenna arrangement was different for FD.

Actually, it was a K1 that was hearing the KX3. We stopped using the 817
when we switched to CW at my station. It wasn't a pure tone I was hearing,
more of a "whoosh," and pretty faint. Not enough to interrupt anything I
was trying to copy. Sometimes I could copy the whooshes, sometimes they
were just noise.

Also, as I recollect, I could only hear the KX3 through the K1 when you
were using the KXPD3. When using your external paddles I couldn't hear
anything.

I understand we are speaking about the KX2 here but I'm curious... would
roofing filters have helped in this situation?

In a recent WWFF outing we had a KX3 and an FT-817 set up. We separated the
antennas best we could but really didn't pay a lot of attention to it. I
believe the KX3 was on 40 and the 817 on 20 meters. The KX3 never heard the
817 but the 817 (no roofing filters I think) washed out when the KX3 was
keyed.

The radios were about 30 feet apart and the antennas maybe 40-50 feet apart.

If the KX3's success was due to the roofing filters installed, could some
sort of external filter added to the KX2 contribute to a solution? Is the
KX3 meant to play well with others while the KX2 is intended more for a
solo trip? I understand W4RT has optional roofing filters for the FT-817. I
wonder if he or someone might come out with a good option for the KX2.

Then again... am I way off base here?
