The Reasoning Behind EO36 and BP75 A letter from Jeffrey (KG0VL) I’m sure most of you have been wondering why my endeavors originate from these two locales. It’s no accident that these two Northern sites were chosen as a spot of personal research for nearly ten years now. From the aurora standpoint, the interesting values are the site’s relationship to one another in regards to their magnetic location. Put simply, the BP75xw beacon site is situated at 66.4283N, whilst the EO36dr spot is 66.6588N (terms geo-magnetic). Thus, the magnetic latitude deviation between the two spots is less than .230 of a degree. The path is 1,735 miles long, with a heading of 313 or 133 degrees, placing the midpoint roughly between the villages of Rae and Yellowkinfe in the Northwest Territories. (too bad the DP22/b is not qrv!) The main objective of my time in the North has been to record (in detail) the time, direction, signal strength, frequency and relative qsb levels of aurora-propagated signals along like paths. This data is later correlated to local magnetometer readings from sites in, along, or near the path. After nearly ten years of study, there are numerous questions that are difficult to answer either mathematically or even logically. As time goes by, the answers to these questions may come forward. I appreciate your time in reading the above and coming to the site. For those of you interested, the BP75xw/b is transmitting on 50.065 from near the village of Circle, Alaska. The beacon is running nearly 100 watts to a horizontal Par Omni, with a keying speed of about 20wpm. 73, and thank you Jeffrey |
