AND8 – an early end

AND8 began on October 14 and was scheduled to last until October 27. Considering that we have to remove the antennas at the end of the DX-pedition, weather forecasts had us consider one week in advance that we might have to shutdown our operation sooner than the scheduled termination date. As the weather deteriorated we decided to reduce the number of antennas and discontinued the southernmost antenna on Oct.24. On Oct.25 the weather forecast for the next day was still pretty bad with an expected sudden change from cold and windy conditions (with intermittent snowfall) to milder, very wet and very windy conditions. With that in mind it was decided to evacuate the receiver site in an orderly fashion. All antennas and other equipment were in safe storage before darkness and we left the area the next morning, well rested for the long return trip to the south of Norway in difficult driving conditions.

Other than this unfortunate shortening of AND8, listening briefly to what has been recorded using NetSDR and Perseus has convinced us that we will have lots of enjoyable hours of listening to our recordings for the next year(s). We will not be surprised if this becomes the most productive of all ANDs when it comes to the number of stations logged. During the first night we had very good signals from southern Brasil and La Plata, the next night was terrific to Brasil. No wonder when the Northern Lights at times brightly covered the entire sky (yes, the weather was very nice the first 5 days of AND8). We were even considering rephrasing that “All sports all the time” moniker used by many sports stations to “All light all the time”.

Generally speaking, lots of DX from the southern half of South America was heard due to coronal hole related geomagnetic disturbances those 5 first nights. Gradually stations from North America became stronger and got more of our attention. Some days we had strong signals well into the afternoon local time, one of those days had stations from southern California and Arizona coming in with exceptional clarity.

During previous ANDs we have to varying degrees struggled with locating and removing noise sources from our setup. While the noise situation was fairly good during AND7, things had improved even further this time, and for AND8 there was no detectable noise during daytime reception. Using the NetSDR as a reference SpectraVue displays an inband noise floor just below -140 dBm. Actually during the first days we even had that very low level inband during nighttime on the southernmost antenna.

We used 3 antennas during AND8. The longest was 1300m @ 255 degrees, then 900m @ 278 degrees and finally 900m @300 degrees.

Everything considered reception was much better than anticipated. This combined with an exceptionally low noise level will inevitably produce a very large log, although we can make no promise as to when it will be published. After all we still haven’t published any AND7 log (we are barely halfway through the recordings ).
