N6GEO & WQ6X do NAQP RTTY as Multi-2

February 22 brought us the winter 2004 NAQP RTTY Contest. I missed the other NAQP GiGs so with NAQP RTTY I easily made up for that. N6GEO and I teamed up as a Multi-2 from his Brentwood Ca. QTH.

WQ6X


We used the same Flex-1500 + Tokyo HyPower amplifier pairs that we ran on St. Croix last month as WP2/WQ6X in the RTTY Roundup (RU).  Each pair was run into a 500-w amp to run more "coolly" at just 100 watts - the NAQP power limit.  We ran these configurations into a multiplexed TH3-jr about 7mh and a ground mounted 6-BTV vertical with a blown 40-meter trap.

This event challenged us with a number of equipment glitches, beginning with a 15-meter bandpass filter failure.  The battery operated MA-500 amplifier developed battery problems early on requiring that we power it off during charging, running the HL-45b at about 28 watts.  Likewise, the other 500 watt amp kept overheating and shutting down requiring power off until cool.  The HL-50 could be safely coaxed to 35 watts during those times.  Even a pair of external fans didn't help much.  I guess RTTY really DOES tax an amplifier; even one running at < 20% capacity.

MFJ Loop & Controller
Not having 40-meters on the 6-BTV hurt us greatly until I remembered that the N6GEO QTH sports an MFJ Hi-Q tunable loop antenna on the roof.  Because it is so Hi-Q the non-tune bandwidth is about 15kc; however it is high-gain in that bandwidth.  Altho the QTH is in an antenna restricted area, most people think the MFJ loop is for some sort of satellite dish access.  I quickly learned the art of calling a station while simultaneously tuning the antenna to resonance.  In less than an hour I made 28 QSO's in 17 sections, as far off as Ontario, New York & Florida - not bad for a stumpy loop.

While the two stations were networked, STN#2 started off signing as WQ6X (instead of N6GEO); a leftover from our WP2/WQ6X operation on St. Croix.   Because we normally use my callsign, I didn't realize we were running as N6GEO until 28 10-meter QSOs were made.

The solution to this problem was to select out the 28 WQ6X QSOs and submit them as a single-OP log entry.  The rest of the log was submitted as N6GEO, satisfying all contest requirements.  In the end, as N6GEO we made 382 QSOs with 147 multipliers, slightly over a 2:1 ratio - not bad for all our trouble.
According to the 3830Scores website we made it to 8th place in the Multi-2 category.
Integrated N1MM & PowerSDR software screens


George and I learned a lot from this event.  Our quick response to the problems we encountered kept us in the contest down to the last 30-seconds.  Because we were using the PowerSDR waterfall displays, it was amazing to watch a screen full of waterfalls disappear at 06:00z, leaving a handful of PSK and JT-65 signals remaining.





Now that we know how to do this correctly, we will be ready for the August
[2014] NAQP RTTY contest - bet on it.

Did you play in the NAQP RTTY?

Is N6GEO in your log?

WQ6X Joins operations @ W1AW/6

Because I usually join team NX6T for ARRL Dx Cw, 2014 was no different; except, that it was COMPLETELY different.  Operators at NX6T's Fallbrook location took part in operating as W1AW/6 in the Southern California participation of W1AW's
centennial celebration.  http://www.SoCalContestClub.Org/Centennial.php

As you can see, different stations/operators volunteered to put W1AW/6 on the air for six days.  At NX6T, operators took on a variety of mode-shifts on Cw, SSB & RTTY.  For the ARRL Dx Cw event, we were assigned 15-meter Cw for the entire contest period.  Other locations were given other bands.  For that reason W1AW/6's ARRL Dx entry will be classified as a checklog.  All contacts with W1AW/6 during the contest WILL count towards DXCC and centennial celebration logs, only the W1AW/6 log "score" will not qualify for any awards; which is a shame as I put on my best ever 15 meter operation for any contest I've ever done.

In addition to 15-Cw, we were given the 80-meter SSB & RTTY evening time-slots on Friday & Saturday.  I was originally slated as a backup operator.  However some schedule changes found me running most of the 15-meter operation (making 597 QSOs out of the 862) and making appearances on 80-meter RTTY and then SSB after 15-meters closed down for the day.

Amazingly, on Saturday evening, I was able to run 15-Cw until 05:30z.  There were still openings to Oceania & Asia but I had worked all the stations that were on, so I shutdown 15 and moved to 80/75.  Because the solar flux was so high propagation was overall quite good until early Sunday afternoon when the geomagnetic storm noise moved in.

While I was quite busy operating, I also found time to put up a webpage about the W1AW/6 operations from Fallbrook (http://WQ6X.Info/W1AW/6/), complete with pictures & links to several YouTube videos made during the weekend.

Because there are multiple W1AW portable operations going on around the country (I've personally worked W1AW/2, W1AW/4, W1AW/5 & W1AW/6), they have changed the callsign in Newington to W100AW.

W1AW and W100AW are a testament to the fact that amateur radio has an incredibly colorful history.  Consider the technological advances amateur radio has been a part of in the last 100 years.
What advances can we look forward to in the NEXT hundred years?
