All the selectivity in the world wouldn't help when the a**hole EU was keying
and swishing his VFO at about 0200Z tonight.
I finally worked them at 0401Z but wasn't sure because of QRM on their freq. So
I kept calling and worked them again for sure at 0414Z. Inverted V, apex at
45', K3S/KPA500. Slot number 14.

I thought I would try VP8SGI this evening on 40M, since I had not tried 40
due to the horrible DQRM almost every night on their TX frequency. They were
pretty loud tonight here in NTx (10-15 dB above noise floor). I use a Delta
Loop at 50 feet. A DQRM was "almost" zero beat on their frequency and 20 to
30 dB louder than them, making it near impossible to copy them. And to top
it off, there were also a few signals very near their Tx frequency also. I
cranked the K3 filter down as far as it would go (50Hz) and tuned the VFO A
just ever so slightly to maximize the SGI copy and throw a few dB more
rejection on the DQRM. After a few seconds, I could copy him clearly to make
the contact.
This was the first time I have had to use that much filtering to make a
contact!
