the question is always WHEN to take those 2-hours. Some operators start an hour or two later
and then end an hour or two earlier. Some operators take an hour break when the propagation gets
dicey, on the hopes that it will again improve, or QSY'ing to the next lower band will make up for it.
~8-hours remaining in the contest event. For this remote operation, the decision was made to use
an MSI gaming-oriented (4-Ghz) laptop, with its relatively stable internet access. The downside to
this approach is that N1MM+ was unable to establish CAT control of the RRC-1258 interface unit, requiring that operating frequencies required manual entry, an encouragement to run frequencies
as much as possible.
end, creating a sort-of "internet jitter" effect. Similar to running remote-Cw a couple of weeks earlier was the need to be able to decode signals in between the dropouts.
(name and state) into the N1MM+ entry screen BEFORE calling in. This at least insured the
correct data made it into the log when the QSO was made.
as in the NA SPRINT contest which usually opens on 20-meters, working down to 40 & 80 later. Around 02:30 it was time to make the transition downward running 40-meters until no new stations could be worked. The rest of the evening was spent "leapfrogging" between 80 & 40 and then back again.
On 80-meters the inverted-vee (@55') offered reasonable coverage between Illinois and Texas
(and all points in between). On the higher bands the 3-el Stepp-IR offers the option to instantly
switch a N-E pointing antenna 180-degrees to pick up a quick KH6 multiplier or run BI-directional. With the Shorty-40, a F/B ratio of 20db means that my 69-watt RTTY was often heard somewhat
off the back end. (The Front/Side ration of yagis are usually quite exceptional.)
of OP-time. Let the 3830Scores score entry document the actual operation. While an 8.7k score
isn't much, it keeps WQ6X callsign recognition very much alive.
was the availability of the necessary filters required to run what I call Stereo-RTTY. The essential idea behind Stereo-RTTY method is to utilize the peaking function of both external audio filters to specifically PEAK the MARK/SPACE tones (effectively deemphasizing the frequencies surrounding the tones).
of 1085-Hz). Running S&P early in the contest enables the opportunity to determine the best L/R filter settings providing the most legible/intelligible RTTY decoding. When running a frequency the aux. notch control in those filters can knock-out single tones from joker's attempting to disrupt legible copy. Also when running a frequency, using the R-I-T control, the desired signal can be centered between the "goal posts". Stations calling slightly off frequency will be shifted away from the goal posts.
with the MARK frequency, their tones often "collide" resulting in garbled copy. By shifting the R-I-T, one of those signals might "jump out of the jumble"
just enough to be copyable over the other callers.
can make for a simple yet effective approach to cleaning up transmit audio. However, remember
to check the audio drive BEFORE and AFTER the filtering - overdriving will of course create new
(and potentially worse) harmonics.
