2021 Report for the 40-MHz EI1KNH beacon

In this post, we'll look at the EI1KNH beacon in Ireland which transmits on 40.013 MHz and how many times it was spotted on the DX Cluster in 2021.


The map above shows the spots for 2021. A total of 21 stations reported the beacon the cluster which is down a little on the 26 in 2020. 

If we count just a maximum of one spot per station per day then there were 52 spots in 2021 compared to 77 in 2020.

Update - 11th Jan 2021: After posting this, I subsequently found out that the DXSummit cluster is missing a LOT of the dx spots for the 40 MHz band. I'll have to rework and update this post.

These are the top spotters of the EI1KNH 40 MHz beacon (again, based on counting just one spot maximum per person per day)


As the map shows above, most were in the region of 500 to 1700kms from the beacon which is a typical distance for Sporadic-E signals at 40 MHz during the Summer season.

The report for the year 2020 can be seen HERE

The EI1KNH 40 MHz beacon which is just to the south of Dublin first became operational in May of 2020.


DX Cluster... If you do hear the beacon then make sure to report it on dx-clusters like DXSummit or DXMaps as some of the other clusters ignore spots for 40 MHz as they assume they're a mistake.

2021 Report for the 40-MHz OZ7IGY beacon

In this post, we'll look at the OZ7IGY beacon in Denmark which transmits on 40.071 MHz and how many times it was spotted on the DX Cluster in 2021.


Looking through the DX Summit DX-Cluster, I could only find 12 spots for the beacon on 40 MHz in 2021 and that was from just 9 stations. This is in marked contrast to the 146 spots from 16 stations in 2020.

(The 21M085 is I presume a CB station in Sweden who spotted it on the DX cluster. He was supposed to be 116km from the beacon so I made a rough assumption about his location.)

I was wondering initially if there was something wrong with the cluster as there seems to have been a large drop in DX spots in 2021.


There were no spots during the months of June, July or August which suggests to me that the beacon was off air during the Sporadic-E season. Considering I can see plenty of spots for the Irish 40 MHz beacons during the same time period, it would certainly suggest that the Danish 40 MHz was not transmitting.

The beacon itself was certainly off air while a fault in the PA stage was being repaired in September & October so perhaps it was operating with no RF output from late May 2021 until the end of August 2021??

Here are the top spotters for 2021...

# of spots for OZ7IGY/B on the DX Cluster

Curious Fact... As of the end of 2021, there are a total of about 500 spots for the OZ7IGY beacon since it first became operational on 40 MHz in 2007. Out of all of the spots, there isn't one from outside Europe. There are no double hop Sporadic-E reports. There must have been plenty of times when the 40 MHz signal was audible in North America and South Africa.

DX Cluster... If you do hear the beacon then make sure to report it on dx-clusters like DXSummit or DXMaps as some of the other clusters ignore spots for 40 MHz as they assume they're a mistake.

Meteor Shower Calendar - April 2021 to January 2022

 


While the Spring months tend to be the quietest in terms of meteor showers, things start to pick up at towards the end of April every year. The peaks of the various meteor showers are good times to check for bursts and pings of radio signals on the VHF bands.

I have put together a calendar which contains a list of most of the current meteor showers. The list below covers from April 2021 to January 2022.
