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?

73,
Kev K4VD

The "whoosh" sound is phase noise, and both RX and TX have it.

Hey D:

Wow! Kinda odd about the paddles. We are going to have to check into that
on the next outing. We have plenty of key options. It would be real
interesting to discover the key had something to do with noise.

By the next outing, we should both have a KX3 on the air! ;)
