I tried to make an improvement to my receiving system by removing a silver maple tree that grew up about 5 feet east of one of the short verticals that contributes to the 2x4 broadside/end-fire phased array. This particular vertical has always shown a much higher real resistance component of the feed impedance than the other verticals. Then this month's QST shows how a live tree can affect an antenna. So away with that tree! I think the result is a somewhat better front to back ratio. Jeff, K8ND, loaned me his DX Engineering NCCC-2. This device should be able to use the pair of short verticals that I arranged to null my transmit signal better than the coax and resonant circuit lash-up I have been using. The NCCC-2 nicely nulls my transmit signal at low power. However, at high power the NCCC-2 overloads on my transmit signal which defeats its utility. So, I continue the coax and resonant circuit nulling device. I am still recovering from the flu and I decided that foremost the contest should be more fun and less drudgery. So I opted to experiment with my operating strategy. Since I inadvertently operated the first night of the ARRL 160 contest with the phased array pointed west without much deleterious effect, I thought I might try a different tactic. I would receive on the east and west Beverages, which are the shortest Beverages here. This scheme has 2 advantages: these Beverages have a broad pattern so maybe I can hear most callers without hunting through all the receive antennas; and the Beverages do not impose a 20 millisecond latency on received signals as does the phased array / SDR combination. The disadvantage is that a really weak signal might go unnoticed. The other abnormal tactic was to stop CQing and go tuning more often. Usually on the first night I can operate for 6 hours straight on the same frequency and maintain a decent rate and work some DX. But I often miss some easy Caribbean or South American multiplier. Also, some European DX that could not hear me excused me from my run frequency when he got US callers after I stood by for a few seconds. So both nights I alternated CQing and searching. Also I did less SO2R type operating since I was avoiding drudgery. Another concession to less drudgery was sleeping for more than 3 hours the first night after UK sunrise. The second night I pulled up the recliner in front of the radio and dozed off between QSOs - there are several 10-15 minute gaps in my log. I wonder how many callers I never heard? Both morning I managed to work Japan. A couple JAs called before sunrise the first morning and JH2FXK called about 25 minutes after sunrise. One more JA called the second morning before sunrise. I heard ZC4A several times but he did not seem to be able to hear outside Europe. I never heard Z60A. IQ9UI called me 3 times over the weekend. A surprise multiplier was VO2NS who gave me "NL" as his province. Isn't "NL" the ARRL section abbreviation for Newfoundland and Labrador? I logged "LB". Another surprise multiplier was TF1AL very late the second night after no more multipliers were expected. Never heard Alaska and worked only 1 Hawaii. Apparently I missed 5W1AS. No Africans and Zone 33 islands don't count so I can't claim Worked All Continents. The end result of my difference operating strategy seemed to be more multipliers and fewer contacts. Even though conditions were pretty good Friday, it doesn't feel like participation was markedly increased, so I am going to attribute the result to my tactics. DX worked: 4X, 5B, 6Y, 9A (3), C6 (2), CM, CT, CT3, CU, DL (28), E7, EA (4), EA6, EA8, EI (3), ES, EU (2), F (3), FM, G (14), GD, GM, GU, GW, HA (5), HB (2), HI, I (3), IT9, J6, JA (4), KH6, KP2 (3), LA, LX, LY, LZ (3), OH (2), OH0, OK (11), OM (6), ON (4), OZ, P4, PA (6), PJ2, PZ, S5 (6), SM (3), SP (9), SV, TF, UA (3), UA2 (2), UR (3), V3, VP9, XE (2), YL, YO, YV, and ZF (2) for a total of 62 entities. There were 157 10 point contacts and 17 non-VE 5 point contacts. Equipment: K3/100, P3, K3/10, Alpha 8410, 2x3 BS-EF phased array, 2x4 BS-EF phased array, 65 foot "Tee" over about 75 radials.
