>Dear OM,

>who operate crystal controlled on 1885 kHz. We vacated 1815 in the early
>1980s due to an increased interest in top band by both CW and SSB
>enthusiasts - no doubt spurred on by the proliferation of quality sets from
>Japan.
> During that period, the "AM Press Exchange" magazine coordinated a

>main criterion was that the frequency be clear of any regularly scheduled
>SSB networks and far enough removed from existing one's that mutual cross
>modulation could be avoided. Frequency 1885 kHz emerged as the most viable
>choice.
> Soon the Editor of AMPE, Don Chester K4KYV, erected a tall tower
optimized for 1885 and began testing. Having just erected a hundred foot
monopole for 160, I began making infrequent contacts with Don. Under normal
fall/winter conditions, both west and eastcoast AM stations could operate
simultaneously with minimal QRM. Thus, 1885 became the national 160 AM
window. These days, just before the day/night transition, K4KYV is often
heard 40 dB over between 4 and 5 PM PST. It is true that national SSB
contacts are more common on this band due to their signal to noise
advantage. In fact, last evening I read your mobile friend AI0WA an "S-7"
after he increased power to 300 Watts near frequency 1885 kHz. I ceased
operating.

read saying, "Shift to SSB and zero beat the carrier." Those of us with
respectable antennas tried to advise the interlopers but to no avail. Was
it malice or could it be they didn't hear us? I lean toward the latter.

David,
I am currently having the same problem on 160. Since the first of the year
a new group of slopbuckets has started showing up on 1888 or 1890 in the
early evening, despite the fact that there has been regular AM activity on
1885 ever since 160 was returned as a full-fledged amateur band, and lately
W8VYZ and others have opened a second front on 1890. The slopbuckets try
come in right between the two AM QSO's and then complain about the AM QRM
even when the band is almost completely devoid of signals +/- 30 kc from the
"AM window". Even though I was less active, I regularly listened from time
to time before New Year's, but never heard these stations before. Since
late December I have become more active now that I have the Beverage antenna
in operation, and can copy most 160M AM signals much better through the
noise. I now seem to encounter this SSB problem every night. It appears
that the SSB group has deliberately chosen a frequency in a deliberate
effort to disrupt existing AM operation on this band.
I am well aware that no-one has a claim over any specific frequency. No-one
advocates this concept more than I do. I have long opposed the concept of
"channelisation" of the amateur phone bands. If SSB stations come on first
and firmly establish a QSO while no-one else is using the frequency, I
respect their right to the frequency on a first-come-first-served basis, and
look for another frequency that is in the clear. On the other hand, I
usually hear the AM regulars in ongoing QSO, with the slopbuckets attempting
to quack away in between. Last night I broke into a QSO on 1885 with WA0ZHH
and a couple of other Texas stations. When I signed out of, someone broke
in with a strong but ricebox quality AM signal and made some remark like,
"Why don't you go stick your head in the toilet and flush it.
We have a coast-to-coast network of AM stations who regularly operate in the
vicinity of 1885-1890 kc, and there is little likelihood that this is going
to change any time in the near future. I do not intend to refrain from
joining these stations when I hear them, just because some two-bit
slopbucket group has decided to try to start a frequency turf war. I do not
consider it deliberate interference to call into an ongoing AM QSO even
though I may be aware that the SSB group is nearby and there is a strong
possibility that I may cause them some interference.
