NAQP is an interesting contest: short, intense and high rates. Unlike the major global contests, the rates are not so high that SO2R is gruelling. 2BSIQ is perfectly doable by those of mediocre skill, such as myself.
I had several challenges in this month's contest, some shared and some unique to myself:
- Conditions: The K-index was 6 early in the contest which mostly affected 20 meters and the low bands. That didn't disadvantage me since everyone was subject to the poor conditions, though perhaps less so for those further south. From this region low angle radiation was preferentially absorbed, favouring low horizontal antennas. For example, on 80 meters the inverted vee outperformed the vertical yagi until late in the evening.
- Antennas: The south-pointing TH6 and the south direction of the 40 meter reversible Moxon were not working. The major impact was on 40 where I only had the high 3-element yagi. As said, low horizontal were superior for the prevailing conditions.
- Preparation: I don't practice SO2R and 2BSIQ. My practice is participating in small contests. Practicing these skills bores me -- I can only take about 5 minutes of Morserunner before getting fed up. Better operators are better because they practice, if only in the days leading up to a contest.
The top 30 low power scores reported to 3830 are shown at right. I did better than I expected, though worse than those with superior skills and tactics, or a superior location. Antenna problems certainly didn't help but that's no excuse.
I parked the Skyhawk (tri-band yagi) at about south-southwest to compensate for the unavailable TH6. The upper 5-element yagis of the 10, 15 and 20 meter stacks were most useful for the western half of the continent so that's where I pointed them; I've done the same in previous NAQPs.
I didn't worry about the east and northeast since there are few stations in that direction and they can usually be worked on back scatter. On 160 meters I stuck with the southwest Beverage receive antenna and relied on proximity to work the northeast.
The presetting of antenna directions is important since there it's difficult to switch antennas while doing SO2R and especially 2BSIQ. I switch antennas or bands when the rate drops to hopefully reach new stations. Never marry a run frequency; agility is key. Activity in NAQP starts on the high bands and gradually works lower as the contest progresses. You must follow the crowd to maintain a good rate.
My objectives for the contest were only partially about the score. Antenna and propagation challenges removed the pressure to do well. Further, I was not on a team containing high scorers. I felt free to experiment and practice my skills. This is what I set out to do:
- 2BSIQ: NAQP is an ideal contest to practice the skill since the rate is high but not too high. Usually there are no more than 2 or 3 stations calling at a time. Although the exchange is relatively lengthy it is pre-filled by call history in most cases. That saves typing but only if you confirm that the pre-fill matching what is sent.
- Receive switching: There are two alternatives for default receive audio switching, and I wanted to practice this as well. My choice until now has been stereo full time, in which the receivers are heard in one ear all the time unless I override to mono, to focus on one for better copy. The best 2BSIQ ops choose to hear the receiving radio while the other is transmitting the other. It is easy to lose track of which radio you're listening to. If both are receiving you hear one radio in each ear, just like for the first option. I set up N1MM Logger+ function key files for both options so that I could switch back and forth. DXLog has more options using its scenarios feature.
- Antenna assessment: I was curious how the antennas would play. That is, whether the less than ideal choices would affect my score. I'd rather not have done the experiment but with the TH6 and Moxon unavailable I decided that I might as well.
The Icom 7600 was limited to about 80 watts due to a DC cable problem which I couldn't entirely resolve before the contest. The 1 db power reduction likely only had a minor impact. The problem was resolved after the contest.
The solution surprised me. After extensive testing I decide my time was better spent buying a new cable. That was how I discovered that the same cable is used on the Yaesu FT950. I have one -- it's my spare rig. Swapping cables returned power to 100 watts. It takes very little resistance at 20 amps to cause a measured 2 volt drop to 11.8 VDC inside the rig.
Before talking about how I did relative to my objectives, the log analysis is worth a look. You can do the same with the Cabrillo file for many of the major contests online using the CBS tool. I used the web interface which is most convenient.

Compared to more skilled operators in this region my performance lags in the opening hours: my rate was about 50% lower. I am focussing on QSOs since multiplier hunting for non-assisted operators doing a lot of 2BSIQ will necessarily suffer. You trade multipliers for QSO points.
The reasons for my under-performance are twofold. One, I persisted with 20 meters at the start when I ought to have avoided it until later. Everyone was on 15 and 10 where the activity was much higher. I've been burned in the past trying too hard on 10 meters leading to the opposite mistake in this contest. I also did more S & P on 10 than I should have, hoping to find multipliers before the band closed. But 10 didn't close early.
15 meters stayed strong for a long time, including short skip to the mid-west US and back scatter from the eastern seaboard. It was a very productive band. My rate increased as the activity gradually concentrated on 15 and 20. Many high scoring stations in this region had more contacts on 15 than on 20. It was that good. I was late to the game. My various high band errors cost me 100 to 150 contacts.
My initial showing on 40 meters was poor, as expected with the high yagi. To deal with it I took my one and only off time from 2300Z to just past 0000Z. That wasn't the ideal off time, however I wasn't do well on 40 and the time fit with my personal schedule (supper time). I operated until 0430Z when I hit my 10 hour quota.
That at least appears to have been a good decision. In previous outings I would take another 30 minute off time mid-evening to take better advantage of the low bands around midnight (0500Z(. This time the low bands were poor and there were few stations to work in the final hour. Skipping the last 90 minutes of the 12 hour contest worked for me.
Let's return to 2BSIQ now that I've analyzed my tactics and abilities, good and bad. Although I have no detailed analysis, my estimate is that 85% to 90% of my QSOs were by 2BSIQ. The remainder were done using classic SO2R: one radio running and the other hunting. That is far more 2BSIQ than I've done before. That counts as success.
To be clear, by "success" I refer only to near continuous 2BSIQ operation and not my score. The negatives were fewer multipliers and frequent gaps (2 or 3 minutes without a QSO) that could have been filled by hunting stations. But you just never know since so many multipliers call when you're running, and many of those time gaps were followed by runs of 4 to 5 QSOs per minute.
- When is a gap so long that you need to QSY or switch to S & P?
- Which mults and how many am I missing by not hunting?
- Many others are also running all the time so I can't work them when I'm 2BSIQ. Does the rate from 2BSIQ compensate for the loss of not hunting the perpetual runners?
There are no easy answers. My typical tactic when switching bands was to start with S & P and resume running when I encountered a clear frequency. That took no more than a few minutes. Other times I'd pick a clear spot on the rig's waterfall spectrogram after a band change and jump straight into running.
Assisted operators were scoring 50 to 100 more multipliers than I was. The comparison is interesting but invalid since we were in different categories. It only shows the potential of how many mults were available. The comparison that mattered was to other unassisted operators. On that score I didn't fare too badly.
The truly talented unassisted operators would operate 2BSIQ almost full time and ask stations to move to other bands. That may be to the other band where they are running or they'd both QSY to the target band. Many stations are surprisingly accommodating to those requests. On the other hand, some say yes (to be polite?) and don't show up. But if you don't ask you won't get the mult. This is a skill beyond my ability. 2BSIQ and even classic SO2R is difficult enough for me.
2BSIQ in NAQP is easier than in major contests like CQ WW or contests with long complex exchanges like ARRL Sweepstakes. It isn't difficult to pick out a full call with no more than 2 to 3 callers; there can be far more in CQ WW. Nevertheless there are many times that I missed calls or copied only a letter or two because my brain was occupied elsewhere or the signal received on the other radio was loud.
Copying errors cost time and can be embarrassing when you ask for a repeat more than once. The other op must wonder why I have difficulty copying a loud signal in the clear. All you can do is shrug and continue. If you let it bother you you'll abandon 2BSIQ or SO2R and that will hurt your score. As one friend put it to me, "shameless" 2BSIQ is the way to succeed. That is, don't worry about the mistakes and plow ahead regardless. Annoyed stations will come back or not, but you'll still come out farther ahead. Indeed, everyone benefits regardless since SO2R increases the overall number of QSO points scored by all operators in a contest. It's a matter of perspective.
I remain self-conscious about my mistakes though less than when I first attempt 2BSIQ several years ago. I am also learning and using techniques to improve QSO synchronization so that I make fewer mistakes and drive fewer callers away by unintended dead air. If I lose my run frequency it's easy to find another in NAQP. The loss can be more costly in CQ WW. CW skimmers will quickly spot your new run frequency.
I made ample use of call history in this contest. It is critical that it be used as an aid and never as a crutch. You are busy enough when doing 2BSIQ that the reduction of typing is welcome, but only if you compare the pre-filled name and state with what is copied. There is no excuse for blindly accepting the pre-fill, yet many do. The resulting error rate can destroy your score since call history is often wrong: names change (guest ops, and SK tributes) and people have more than one residence.
The bottom line is that I'm pleased with my NAQP CW result. I learned what I can do and what I can improve. However, I am not ready to tackle 40+ hours of 2BSIQ in CQ WW, with a dozen callers on each running radio during the peak of openings to Europe. I doubt that I'll ever reach that skill level, and I don't know if I want to try. Maybe it'll be easier when sunspots recede and the high bands aren't all open at the same time.
I made improvements to my operating desk layout a year ago to improve situational awareness. I've kept it that way (see pic at the top). Both radios are up front with the monitor on top. There are several visible indications of the operating state:
- Transceiver LED and meters to distinguish receive versus transmit status
- N1MM Logger+ Entry Window TX/RX button lights.
- N1MM Logger+ scrolling text for what is being transmitted, or has just been transmitted
That should be enough. However I find the N1MM indications difficult to follow. The TX/RX indicators are small and must be looked at directly, since they are almost invisible in peripheral vision. The scrolling text is tiny and similarly difficult to see and follow unless looked at directly. Frankly, I don't like it. The rig power meter LEDs are more helpful since they're bright and large.
If you use one keyboard, the logging software places receive focus on the correct radio in this case so that what you type is for the correct radio. Although that would seem to favour use of a single keyboard the situation can quickly deteriorate when both radios are receiving. That is when 2 keyboards can be much better, by removing all doubt as to which radio your typing is for.
The core of the OTRSP commands for the N1MM Logger+ function keys originally come from N2IC and have been widely copied. These ensure that you are only listening to the receiving radio when the other one is transmitting:
F1 Cq,Test {MYCALL}{OTRSPOTHER RX}{END}{STEREOON}
F2 Exch,{SENTRSTCUT} {EXCH}{OTRSPOTHER RX}{END}{STEREOON}
F3 Tu,Tu {MYCALL}{OTRSPOTHER RX}{END}{STEREOON}
I made two function key files before the contest with and without these OTRSP directives. As in the past, it didn't last long. The combination of visible indication deficits and my own skill level defeated my attempts to follow the QSO flow. After 10 minutes of 2BSIQ I reverted to manual stereo control for the remainder of the contest. This involves pressing the ~ key to turn stereo on and off as needed to copy one station without the other radio getting in the way.
It's more work but I was never confused as to which radio I was listening to. Using the keyboard controls is a more sophisticated method of receive audio control than what I began with several years ago. Of course you need an OTRSP device, which in my case is the SO2R Mini.
There is much more to say on SO2R and 2BSIQ but this article is long enough. I may go into more depth in a future article. Not because I'm so good at it, which I am obviously not, but because it might be of interest to those considering SO2R and 2BSIQ. Others might benefit by learning from my successes and failures.
I'll speak briefly about NAQP SSB this past weekend. I made only 100 contacts since the contest doesn't have a great appeal to me other than as a casual operation and to say hello to friends. It can even be quite relaxing on a winter evening. My sole objective was to set the station up for phone SO2R which is more difficult than for CW. TTS (text to speech) has to potential to make 2BSIQ as easy as on CW, but that was not my purpose at this time.
I ran into numerous difficulties getting message playback from the PC to each radio's internal codec and to route the mic to each radio. When you speak the other station's call sign or anything other than play the pre-recorded messages you must ensure the mic is connected to the transmitting radio. You must also use VOX or a foot switch for that radio. I installed two foot switches as many do for improved situational awareness. Switching the mic and transmit focus isn't trivial and I ran into trouble setting this up with the SO2R Mini.
I need to get it working, not so much for myself but for requests I've received from prospective guest ops. This is one more project added to my long list of winter projects. Well, the wind is howling and the snow is piling up so I might as well see what I can do.
