Danish 40 MHz beacon heard in Ireland - Sun 9th June 2019

There was a good Sporadic-E opening on Sunday the 9th of June 2019 with both Phil EI9KP and myself managing to hear the OZ7IGY 40 MHz beacon in Denmark.

The distance from the beacon is about 1345 kms for Phil and 1390 kms for me.

The screenshot above is from the DXMaps website which has a special page for 40 MHz reports.

Considering the low level of activity on the 40 MHz band, this page is normally blank so it was unusual today to see two traces on it!

These are some of the spots from the DX-Cluster...

EI7GL-@ 40071.0 OZ7IGY 11:37 09 Jun PI4 -19 dB Q=44 es Denmark
EI7GL-@ 40071.0 OZ7IGY 11:26 09 Jun PI4 -14 dB Q=64 es Denmark
EI9KP 40071.0 OZ7IGY 10:53 09 Jun IO54MB ES JO55WM S9 PI4 +20dB Denmark
EI7GL-@ 40071.0 OZ7IGY 10:31 09 Jun PI4 -8 dB Q=100 (es) Denmark
EI7GL 40071.0 OZ7IGY/B 10:21 09 Jun IO51TU ES JO55WM 8m bcn Denmark
EI9KP-@ 40071.0 OZ7IGY 10:08 09 Jun PI4 20 dB Q=100 1345 km es Denmark

The PI4 in the cluster spot refers to the PI4 software which decodes the OZ7IGY signal which alternates between giving out its ID in morse and in PI4.

The amazing thing about the PI4 software is that it can hear the signal buried in the noise. When I uploaded my last spot, it was -19dB and I couldn't actually hear the signal but the PI4 software was able to dig it out of the noise.

More information about this beacon and the PI4 software can be found on the OZ7IGY website.

First Sporadic-E crossband contacts made from Ireland on 40 MHz...Sat 25th May 2019

Following on from news of the inter-EI activity on 40 MHz last weekend, here is a report of the first crossband contacts made on the 8-metre band via Sporadic-E.

Phil EI9KP has sent on the following (in Blue)...

Saturday 25 May 2019.
I noticed there were strong Es signals from Europe on 10m and 6m.  I activated the 8m ‘beacon’ keyer on 40.250MHz (CW, call and locator, 30s cycle, 5W, Delta Loop, HP) but was unsure how to actually get feedback.   I posted a message on KST Chat but there was no immediate response.  Eventually I just started calling on 50.185 later on 50.250 just saying something like “have CW beacon running on 40.250 looking for reports, feedback XB on this frequency …).  I had about a dozen QSO’s in-band on 6m but those HAMs did not have receive capability for that unusual frequency.

At 1526 UTC in QSO with DG1VL on 50.250MHz, he listened on 40.250 and reported hearing my beacon 599 in JO61WB.  I subsequently changed the FT-857D to USB and we had a full 2-way cross band QSO 40.250 8m / 50.250 6m, with 59 signals.  This was my first 8m/6m cross band experience and I believe it is a first in EI cross band 8m/6m to Europe. 

At 1615 UTC in QSO with OK2KG (JN89JI), a similar experience XB 8m/50.250, first getting a beacon reception report then switching 8m to SSB for a 2-way QSO, with a 53 signal report.

Both stations were using their 6m Yagi for receive so not really optimized for 8m, however, it was just an amazing experience and totally unexpected on “Day 1” of my experiment!

Sunday 26 May 2019.
At 1424 UTC in QSO with DK7ME (locator JN47TN) on 50.250, excellent 59 signals both ways.    He reported hearing my beacon on 40.250MHz and I switched to SSB for a 2-way QSO 8m/6m.  I heard EI4GNB’s beacon earlier on the day and asked Carlos to listen on 40.300MHz; he subsequently reported hearing Tim’s beacon in IO63WE.  That’s interesting in a way as the 40MHz ‘zone’ at the time seems to cover EI East Coast to West Coast, a much wider area than I am used to on 6m propagation, it’s just an initial observation. Great for him catching 2 EI beacons in a day!

S57UHX (locator JN65UN) was following the above QSO unfortunately 6m propagation faded out so we did not have QSO on 6m, however, he reported (by email) receiving the 40.250MHz beacon 51.

What Sp-E skip distances to expect on 40 MHz?? 

Inter-EI activity begins on 40 MHz...

In April of 2018, Irish (EI) radio amateurs gained access to much of the low VHF spectrum including 40 MHz. Some short distance contacts were established in November of 2018.

Over the winter months, several EI stations have been busy getting ready for the new 8-metre band and this has now resulted in more inter-EI 40 MHz activity.

Thanks to Phil EI9KP in Co Sligo who has sent on the info on all the activity.

Both Phil EI9KP and Tim EI4GNB run manned beacons on the band. Over the weekend of Saturday 25th and Sunday 26th of May 2019 , they both managed to hear each others beacons at a distance of about 208 kms.

This is all the more impressive as the Dublin mountains block a lot of the signals from the west of Ireland getting into Bray where EI4GNB is located.

Here is a report from Phil EI9KP....

In EI there are two manned beacons running i.e. On air when supervised in the shack.  Info below by coincidence Tim and I are using the Yaesu FT-857D in ‘beacon mode’ for this purpose. An interesting set-up which allows us to switch to SSB for in band and cross band QSO.

EI9KP in Aclare, Co. Sligo (locator IO54MB): FT-857D, chosen freq.: 40.300MHz, mode CW, power 5W, antenna: Delta Loop horizontally polarised.  Site agl: 200m.

EI4GNB in Bray, Co. Wicklow (locator IO63WE): FT-857D, chosen freq.: 40.250MHz, mode CW, power 5W, antenna: 2 element quad horizontally polarised.

Saturday 25 May 2019:  Listening on 8m band I heard fragments of CW on 40.300MHz, some searching on the web pointed me to EI4GNB and I asked him to turn the antenna north west and  confirmed report 515 via KST Chat.  I activated my beacon on the same frequency and he confirmed report 555 after a few trials due to local QRM.

Propagation type?  Was it purely ground wave (diffracted) or tropo or something else?  We are not sure, the distance is a good 205km.  Tim reports experiencing similar propagation on 6m receiving EI3KD from time to time.  I’ll be watching his beacon signal over the next month or so.

The next day, Phil managed to make a two way SSB contact with Andrew EI3FEB in Co Galway, a distance of about 65 kms.

Again, I'll let Phil outline the contact...

Sunday 26 May 2019:  I had a sked with Andrew EI3FEB in Headford, Co. Galway (locator IO53KL).  On a test previous week on 40.250MHz we could not make contact, not even hearing a blip, it appeared our antennas were not correctly aligned for ground wave.  

Both Andrew and I are using a Delta Loop in Horizontal Polarisation;  the delta loop has a noticeable null on the tips, this time we were aligned broadside.  Success:  a 2-way SSB QSO with 5/1 reports both ways.  Distance is 65km, diffracted signal (one hill in the path).

If you are in the UK, have listen for the beacons if there is tropo about. Likewise, these signals should be easily heard on the continent when there is Sporadic-E.

Both EI9KP and EI4GNB can be contacted through their respective QRZ pages. Also look for them on the ON4KST chat page.
