Equipment
Following last year, when a generator failure at the start of the contest effectively forced us off air we wanted to be sure of the status of equipment this year. Thanks to Ken G4XCB an alternative generator had been sourced. This device was, perhaps, a little less sophisticated than the ill-fated inverter generator employed in the previous year, however, what it might have lacked in sophistication it made up for in key areas, it offered 2500W with a 2800W peak (plenty to run our station for the weekend) and most importantly when tested under load it carried on providing power!
With power sorted out much of the remainder of the equipment was as it was in previous years, as is common we had to augment the Club equipment with some members equipment:
2m Station
- Club 14 element Yagi
- Club 8m mast
- Club tripod stand
- Club rotator and controller
- Club Yaesu FT-991
- Club Behringer 302USB audio mixer (used to provide separate headphone feeds to operator and logger)
- Club HP “Training” laptop no. 1 for logging with MINOS
4m/6m Station
- Club DB-46M8EL dual band, 4/6 metre Yagi (donated by Ray G3IOI)
- Club swaged pole mast (donated by Dave M7BBN)
- Members drive on tilt-over base (Norman M7BBZ)
- Members rotator and controller (Norman M7BBZ
- Members Yaesu FTDX710 (Norman M7BBZ)
- Club HP “Training” laptop no. 2 for logging with MINOS
We usually employ two separate power supplies, one for each station, but somehow the Club’s secondary PSU, a Manson EP925, didn’t make it to the Field Day site; so we had to rely on the Club’s Nissei DPS-300 Linear Power Supply for both stations. One of the advantages of competing in the low power class is that input current isn’t that high and the Nissei supply was quite capable of driving both rigs at 25W (10W on 70MHz) output.
Logistics for Field Day are more complex than for some of our regular Special Events. Not only do we operate two stations in three sections of the contest but we have to do this with no support in the form of power sources, accommodation, catering etc. The logistics usually fall to a small handful of people within the Club.
This year turned out to be surprisingly windy which made the erection of the 2m beam particularly challenging. This antenna is large and quite weighty, we managed to get the mast rotator and antenna up but a sudden gust of wind before we were fully tied off brought it back down again, fortunately no one was in the path of the antenna (although Norman was pretty close as it fell) and although there was some damage we were able to effect a field repair to get back up and operational.
Other issues were the Club Rotator and controller seemed to want to rotate continuously despite inputs to the contrary, there was no obvious solution to this other than leaving the controller turned off and only activating when we wanted to change the beam heading.
We had new coax to put on both antennas, this needed to be cut and soldered on site which took a whole lot longer than anticipated making us late to get on air, but despite all of these incidents, including Ken’s “screwdriver” injury (which allegedly had something to do with Mark M0SKV) we got both the 2m and 6m station on air.
Late on the Saturday we noticed that the laptop clock wasn’t synchronised so the log was corrected post event. We sync’d the clock after the 6m contest closed to avoid a repetition of this error during the 4m contest on Sunday. Sunday had a momentary hiccup when we discovered that although a UK spec FT710 is capable of transmitting on 4m you have to enable this within the menu by switching to the UK profile, something that isn’t done out of the box. Fortunately we had enough time on the Sunday morning to work out what needed to be done and implement the change.
6m Results
The results presented below have been determined following analysis of the unadjudicated log, and will not be updated once results are known.
Number of QSOs
Table 1, below, presents the disposition of QSOs across the operating period and calculates both the average QSO/Hour and by how much each hour deviates from the average. This table when tracked over a number of years can provide an insight into the best times to operate.

The late start was a direct result of having to prepare the new coax feeder but also because personnel who would have been operating the 6m station were repairing the 2m beam after the wind brought it rather violently to the ground. The QSO rate of 8.5/hour overall is slow, basically one QSO every 7 minutes. There were busier times: 17:00 – 18:00, 19:00 – 20:00 and 20:00 – 21:00 when the QSO rate picked up peaking at 13 per hour or 1 QSO every 4.6 minutes but it couldn’t really be described as a “pileup”!
Points Scored
Table 2, below, presents the disposition of points scored across the operating period and calculates both the average points/QSO and by how much each hour deviates from the average. This table when read in conjunction with the QSO rate above can provide an insight into the best times to operate, as it is not always the most frenetic periods that yield the best distances.

The band clearly changed around 18:00. Prior to then the average QSO distance was around 400km – 600km, however after 18:00 this jumped up to 1100km – 1300km, our best DX was worked at 19:10. As we were only operational for 6 hours patterns are harder to discern; hours 3, 5 and 6 were busy in terms of the number of QSOs but also good points scoring periods. Hour 4 bucks this trend by being only 12% of the QSOs worked but delivering 17% of the points scored.
Distances Worked
Tables 3 and 4, below, present a summary of the distances worked. The best DX on 6m was 5B4AAB at 3337km

These tables are produced using a spreadsheet, this year on 6m we had to add 3 new countries: Bosnia and Herzegovina, Latvia and Serbia. Looking at the UK list, it is very limited with only “E”, “M” and “W” being worked on 6m, although given that over 50% of contacts were into Europe this is perhaps not too surprising. It doesn’t however help with our quest to work all RSLs in a single event.

We normally get round to uploading our Field Day contest logs to eQSL.cc, but otherwise do not exchange QSL cards in this event. If you wish to QSL traditionally please send information via the RSGB Bureau.
The average error rate for this band was reported as being 5.64%. We came first in class on the 50MHz (6m) band.
4m Results
The results presented below have been determined following analysis of the unadjudicated log, and will not be updated once results are known.
Number of QSOs
Table 1, below, presents the disposition of QSOs across the operating period and calculates both the average QSO/Hour and by how much each hour deviates from the average. This table when tracked over a number of years can provide an insight into the best times to operate.

This follows an expected pattern, because we were on air at the start of the contest, having addressed all of our immediate problems the previous day and having had sufficient time before the contest starts to make sure the rig was able to transmit on 4m our start coincided with everyone else and we quickly worked 75% of the stations we were going to work within the first two hours. After that it was slim pickings as we tried to winkle out those illusive unworked stations.
Points Scored
Table 2, below, presents the disposition of points scored across the operating period and calculates both the average points/QSO and by how much each hour deviates from the average. This table when read in conjunction with the QSO rate above can provide an insight into the best times to operate, as it is not always the most frenetic periods that yield the best distances.

Points scored tracked quite closely to stations worked; as there were no special long distance QSOs this is not surprising.
Distances Worked
Tables 3 and 4, below, present a summary of the distances worked. The best DX on 4m was GM4ZUK/P at 617km

Table 4 – Statistical Analysis of Distances Worked (4m)

2 Standard Deviation | 252.38 | 96.97% |
3 Standard Deviation | 378.56 | 96.97% |
The best DX is again a bit of an outlier, at 617km it is more than 3 standard deviations from the mean, which puts every other data point within 2 standard deviations of the mean. The next highest distance is 389km, within 2 standard deviations of the mean.

Similar to previous years the bulk of our contacts were within the UK, this helped a little with our quest to work all RSLs in one event as 4m yielded Guernsey (well technically it was Alderney but it’s still “GU”). Thanks to EI9E/P for our only out of UK contact.

83 QSOs is not as high as some years, and the distribution of contacts is relatively flat. Working on 2m was a bit of a chore most of the time. Most contacts were worked between 16:00 – 17:00 on Saturday and in the last hour of the contest on Sunday. 17:00 – 19:00 on Saturday was also a productive time.
Points Scored
Table 2, below, presents the disposition of points scored across the operating period and calculates both the average points/QSO and by how much each hour deviates from the average. This table when read in conjunction with the QSO rate above can provide an insight into the best times to operate, as it is not always the most frenetic periods that yield the best distances.

Points scored tracked more closely with the QSO count, probably because we missed out on the initial 14:00 – 15:00 flurry of early contacts due to the coax and antenna issues. Once again the valuable stations ere caught early on Sunday morning with 07:00 – 09:00 being responsible for nearly 18% of the total points scored but only accounting for 8.5% of the total QSOs. These two hours were the only time our hourly average points/QSO topped the 300 barrier!

This is the only band this year where the population within 2 standard deviations of the mean is different to the population within 3 standard deviations of the mean. As with both 50MHz and 70MHz the best DX is an outlier being beyond 3 standard deviations of the mean.
