After about a month using a 75 Watts stand by transmitter, Radio208 on 1440 kHz is now back with 500 Watts, using the old 1 kW CCA transmitter from 1974. A new cooling system has been installed.  Radio208 operates 24 hours a day seven days a week with a rock/alternative music format from a transmitter site in Ishøj, in the South Western outskirts of Copenhagen.

WNRP 1620 kHz, Gulf Breeze, Florida (serving the Pensacola area) seems to be at their higher daytime power of 10kW tonight (0300 UT 15 September) as Hurricane Sally is approaching the Gulf Coast. The station is heard on top of otherwise dominant Radio Rebelde outlet from Cuba on the same frequency here as received in the Atlanta, Georgia area. WNRP typically rebroadcasts WEAR TV audio from Pensacola during that station’s local TV news broadcasts. There was storm related information tonight but it was disappointed WNRP switched back to their normal evening Conservative talk radio format during other times not on top of the hour. Not quite living up to their branding as “News Radio 1620”. As the storm approaches and makes landfall maybe they will switch to more actual local news.

Norway

According to an email received today from NRK Publikumsservice the new transmitter, which is in use on 1485 kHz NRK Longyearbyen Svalbard, installed in spring 2020, is still running 1 kW, and not 3 kW.
They are awaiting approval from The Norwegian Communications Authority (Nkom) to increase power.

Spain

The CEO and owner of EAJ29 Radio Inter, Madrid, 918 kHz, and conductor of the morning magazine of this station, Carlos Peñaloza, said some days ago on air that they would install a 100 kW transmitter to replace the old, german tube 20 kW transmitter (I guess Telefunken) which has been on air in a precarious state from long time ago, with years of damaged performance, with loud heterodyne noise, beating hiss and unstable carrier. 
In the last decade, the company entered in a decadence and the facilities, neglected, had a historic of outages of the signal, up to more than a week off air, and the site had been even vandalized some years ago with the cooper being looted and other damages. 
I must note that the license the owners have for EAJ29 on 918 kHz is for a power up to 50 kW, and no more, as do EAJ2, EAJ7, EAK1 in Madrid, EAJ1, EAJ15 and EAJ39 in Barcelona, EAJ3 and EAK5 in Valencia, etcetera. None private station on medium wave in Spain is or has been, allowed to use more than such power. 
For the moment the station is off the air, only available on tiny FM frequency and streaming. Mr. Peñaloza also informed the audience about the good speed of the restoration works of the facilities.

Ukraine

I got some news about 648 kHz in Ukraine.
Radio “Crimea.Realii” plans to increase the power of the transmitter.
It now operates at 10 kW power. They got financial help from the US to
buy a 25 kW transmitter.

Judging from the signal levels, the tx upgrades for NRK in Longyearbyen [1485 kHz] must have been done. I saw someone mentioning 3 kW somewhere? 1480 and 1490 now blocked here.
Bjarne Mjelde to DXing.info fb group (2020-09-05)

The transmitter was replaced in spring 2020 but continued running just 1 kW. The entire installation should be upgraded during this summer.

Due to a problem with the cooling system in the main transmitter for
1440 kHz (500 Watts), Radio208 is as of August 21st at 16 UTC using the 75 Watts stand by transmitter. It is hoped that the cooling system can be repaired within a week or two, and so Radio208 will hopefully be able to resume operations with full power: 500 Watts.

Australia

The ABC faults and outages web page is unfortunately currently more difficult to rapidly obtain information. Previously, all Australia wide transmitter outages were listed on a single page. This made for a quicker assessment of what key high power transmitters were temporarily off air (e.g. 612 and 792 KHz Brisbane).
Currently there is no other option than to manually type in single post codes (or location) one at a time. Today I typed in 2000 (Sydney), and the following planned outages were listed:
Thursday August 20, 2020. 12:06 AM to 1:00 AM, 2:06 AM to 3:30 AM:
576 KHz 2RN Sydney off air.
Thursday August 20, 2020. 1:06 AM to 3:00 AM: 702 KHz 2BL Sydney off air.
Thursday August 20, 2020. 2:06 AM to 3:30 AM, 3:30 AM to 4:50 AM:
630 KHz 2PB Sydney off air.
Thursday August 27, 2020. 1:06 AM to 2:00 AM: 576 KHz 2RN Sydney off air.
Thursday August 27, 2020. 3:06 AM to 4:00 AM: 630 KHz 2PB Sydney off air.
Thursday August 27, 2020. 2:06 AM to 3:00 AM: 702 KHz 2BL Sydney off air.
Hopefully this will be an opportunity for technical staff to fix the 630 KHz 2PB issue. It will also be an opportunity to check for distant signals that are not normally available on 576, 630, and 702 KHz.

United Kingdom

While listening to the football sports coverage of BBC Radio 5 live in the evening (e.g. 7 August 2020), I wondered why I could only listen to 693 kHz while 909 kHz was dominated by Romania.
According to
https://www.bbc.co.uk/reception/issues-with-analogue-radio/#/undefined work continues at the Brookmans Part station.
“Essential engineering affecting MW Radio 5 live service in London and the South East – 27th July – 4th September.
Brookmans Park Transmitter.
Essential engineering work is taking place on the Brookmans Park transmitter that will have periods of reduced power and shutdowns between 10.00 – 16.00 on week days and some Saturdays between the 27th July and 4th September.
Listeners’ access to Radio 5 live may be affected during this time period.
You can use our Transmitter Checker which will give you an exact view of the current status of the transmitter and any recent changes.We would recommend not re-tuning your Radio’s during this period of essential engineering.”
