"Around Poland" VHF dxpedition - WET squares event

After a week of "Around Poland VHF dxpedition" activity on the mainland squares, a special event is planned :-) 
Luckily convinced Mek, he should go sailing, and voila! 

Donors list updated - THANK YOU for your generous support !

First EVER 70MHz activity from 

WET squares 

JO85xa and JO95aa 

will take place soon. 

planned JO85XA90

planned JO95AA00
Map sources : TK5EP map locator https://www.egloff.eu/googlemap_v3/carto.php

This event is scheduled for weekend July 25th - or 26th as we are limited by weather, more info TBA later.
Each square will be activated for 5 full hours, so full day sail is scheduled, adding 2+2 hours for sailng forth and back.
 
Fishermen's boat "HARPUN", already checked by Mek, with 230V power for SSPA on board :-) antennas will be attached at the back, both 3 ele YU7EF for 6m , and 2x2el (wide angle) for 70MHz.

Temporary shack for 6 and 4m equipment, and operating place.

Some of You already worked DL guys on 6m (DL3BQA / LY2AAM and Co.) on their way back home from one of their Baltic VHF expeditions, but certainly none of You worked theses squares on 70MHz.

To make this happen, we are seeking for your help. 


 Previously we never asked for it. 

 But renting a boat for whole day sail, is unfortunately quite expensive. 

Overall costs of renting this boat for full single day event on the Sea will exceed 500 Euros.

If You want to help with this special event please consider ANY donation.

Donors : OZ1JXY, PA2M, G4BWP, OZ2OE, PA3BIY, S57TW, DL6BF, DK8NE, DK2GOX, PA3ECU, S51DI, Dk2EA, OZ8ZS,  and? You?


All donors will get their QSL card free of charge, also special "coffee" mug is planned as a gift for those who make highest count of active squares during the Around Poland VHF x-pedition.
Donors callsigns will be updated here on the page.

"Around POLAND" VHF dxpedition

I am honoured to present another project of Mek SP7VC and Kasia SQ7OYL for this VHF Summer.

Because of COVID-19 restrictions and problems with traveling around EU, and other safety reason his previously planned for the Summer Iceland 2020 Tour has to be postponed.

But as unsettled soul, instead of Iceland, Mek planned some other domestic activity - with hope that many of You will work missing gridsquares in Poland on 50MHz and 70MHz.
In addition activity on 3 & 6cm band via RS is possible.

Multiband equipment with 50/70MHz YU7EF Yagis, 9el Yagi for 2m and 60cm dish for 3&6cm, and reliable equipment IC7300 / IC-9700 / FT-847 / FT-290+trsvt and SSPA's will be used with SSB, CW, FT8, MSK144, possibly dualband same time where possible.   

Look at the map below, and note in Your calendar dates interested for You.



Trip is scheduled as follows :

July 19 from JO92, JO82, JO72, JO73, JO74, 

July 25 (or 26) JO85 - JO95 WET squares event - READ MORE IN NEXT POST
 
July 27 - JO94, KO04, KO03, KO14, KO13, KO12, KO11, KO20, KN19, KN09, KO00, JN89, JO80, JO70, JO71 

For any question concerning dates and certain squares needed  - please contact Mek directly by e-mail SP7VC@WP.PL to give him a look where to stay longer. . .

Stay tuned for more info!

Noisy QTH? Tell me more.

As You probably QSO'ed me on 4 or 6m You know my QTH was almost noiseless few Years a go.
But time flies, and 2-3 Years a go situation started to get worse. 
Apart of small noise sources we can observe on 50MHz everywhere where we can find humans :-), it's time to add another which is bigger than anything before.

If Your neighbour decide to put PV on his roof, that can be shot in your heart.

Actually, your heart will suffer attack later, after You see what You get as surplus of his new shiny braight PV panels...

There are some screenshots from my IC-7300 waterfall, showing some noise conditions, with antenna pointed side to neighbours house, approximately same height as PV panels at distance ~50m.

2019 , September :




 Can be worse? Yes...

 2020, May 1st, sunny, no clouds.




2020, May 3rd, little clouds - lines got thinner - if sky gets cloudy noise matrix decreases a little, after dark almost dissapearing, but leaving something like screen noise on the background.






Rising count of Photo-Voltaic devices causing more and more QRM for us. Actually I am resigned, and looking for any place away from home to put remote RX station. There's no way to copy anything amongst this shitty QRM. Only directions left is East, There are points where antennas back null in pattern can lower the noise some 10-15dB. Not much better on 70MHz. Almost the same as on 6m.
Pointing antenna somewhere 230 - 360 causing waterfall getting white and no signals can be heard.

Spoken with friends noticed new PV in neighbouhood, almost same QRM on waterfall.

Will see what we can do about it, letter to the regulator is on the way.

So if You think your QTH is noisy, pray nobody will install something like this.

Germany new 50MHz regulation

Great news for German hams came today :

Effective of today German Regulatory Office "BNetz" released new regulation for 50MHz use in Germany. Following agreements set at WRC-19 conference from today on, German hams can use frequencies within 50.000MHz - 52.000MHz on secondary basis.
 
But what is most important, also allowed power limits are increased from 25Watts PEP to 750W PEP in 6m subband 50.000-50.400MHz for class "A" licence holders. 
Owners of class "E" licence are allowed to use 100W PEP within this segment of magic band.
Part of the band above 50.400MHz is still covered by limited power of 25W PEP.
 
Compiled from Internet news signed by DK2ZC, DARC Frequency Manager
  
Congrats guys!
