This was "measured" with a 10 dollar AliExpress EMF meter on a roof. Over 1900V/m.
The real measured value with a calibrated Narda was less than 2V/m.

On a roof for #5G modernization and we found "unknown antennas".
These are probably the ones of ATV #repeater PI6HVS in Hilversum. On #70cm, #23cm, #13cm and #3cm

Many thanks for your reply and photos. This will give me more inspiration.
Added another passive heatsink.
Now also with a 12v fan underneath for the hot summer days.
I can also try with thinner air filter.

Installed a fan tower and special case for cooling my web888 #websdr but after 60min already 45C in a 18C room.
I have to find an better solution.
Fan is running at 12v at highest speed.

Ik werd vlak voordat ik ging stemmen beïnvloed om dit te doen. Er hing buten een bordje: "stem lokaal".
Pileup of 3Y0K Bouvet is now on 20m and is 34 kHz wide.
The UP police is also very active.

Do you use http or https?
Try http
Great!! Well done 🫡
My 2nd #kiwisdr in now on air. This is a v2 running next to the version 1.
V1:
pe1rdp.no-ip.org:8073
V2:
pe1rdp.proxy.kiwisdr.com
Both running on a wellgood preamp and wellbrook loop.
#hamradio #hamr #AmateurRadio #HF #SDR #radio #antenna
So I took a #vacuum #cleaner #filter to prevent getting dust into the #websdr
But, this blocks the airflow too much and #temperature is now 43 degrees already.
Back to the drawing table.
Maybe this heatsink will help?
#hamradio #hamr #AmateurRadio #CPU #fan #Web888
Turning the fan of the #Web888 was a success. #temperature drops from 42 to 37 degrees in a 18 degrees room.
But now the fan is blowing dust into the #websdr
Will this #filter be a good solution?

Succes Rob.
Ik weet zeker dat je deze moeilijke maar ook zeer boeiende taak als MP aankunt.
The #fan of the web888 #websdr makes too much noise but I found a Sunon maglev 40x40x10 in the junkbox. This fits perfectly in the web888 and the fan grille protects my fingers also.
Now skimming #FT8 to monitor propagation for ARRL #cw #contest

QRV in PACC #contest during spare time.
Also helped building this 80m vertical #antenna at the station PI4KAR.

Arrghhh! One earphone pad of my Arlan Radiosport broke and the silicone drips out.
Spare is available for 50 UK pounds! But this AliExpress works fine: 5 euro for 2 cups.
Also made cable mod to mini XLR.

The Belka is no longer for sale. I bought mine on a second hand website.
Enjoying a full QRM free environment.
Temperature 12 degrees, sunny and sitting in the forest with my #Belka #HF #receiver listening to #CW signals on 10m. Report 519. Lovely.
