A recent post on the so-called "freebanders" on 30m mentioned the =
idea of "other"kinds of interference in the CW portion of other bands. =
It would seem that most of us are primarily CW ops ( an assumption on my =
part ), so I wanted to get your opinion on some "other" interferene I've =
been running into on an increasing basis in the CW portion of the 20 and =
40 m band. =20
Late at night I go into the DX portion of 20m, but you will =
usually find me between 14.035 and 14.050, and between 7.025 and 7.040 =
on 40m, definitely out of the digital portion of either band. I'll have =
a nice QSO going, and out of the blue appears the burbling sound of =
digital HF. It is unmistakable.=20
The "Gentleman's Agreement" notwithstanding, it is a reality that =
the bands are crowded, and at times we operate wherever we can find a =
reasonably open frequeny. On 40m the frequency doesn't have to be open =
at all for someone to start sending CQ out of the blue. Have any of you =
noticed the increased activity of digital signals below the digital =
sub-bands? What bothers me more than their presence is the fact that =
they are so resistant to QRM, so much so that they often just start =
transmitting, seemingly without any awareness of any other signal on the =
frequency or even nearby. I was working a station with an honest 599 =
recently who was totally buried by a digital station, and we were =
certainly out of the digital portion of the band. I don't care that =
they are there, I just wish they had a way to ask "is the frequency in =
use" and would do so before they start their digital burbling. Anyone =
else notice this?
