Australia

1170kHz 2CH (callsign) broadcasting as 1170 SEN Sydney (NOT as SENTrack as listed incorrectly in Dan’s active sheet) commenced using 7.5kW of power during the day only in July. The station is now trailing 10kW during the day (5kW night).
Also please note Crocmedia name was recently changed to Sports Entertainment Network.
See: https://www.sen.com.au/news/2020/09/29/crocmedia-re-brands-to-sports-entertainment-network/
The old ‘2CH’ music programming now only exists on DAB+ and as a Internet streaming radio station, owned by SEN.

Although, as you wrote in the news, 109 LPAM stations have a license of this list https://www.radio-tv-nederland.nl/am/am.html , only about 50% are really on-air on a regular base, e.g. 12/7 or 24/7. Many stations are still under construction, some have their license for YEARS and not one second even online. Some stations are only 2 hours on-air on Saturday (11~13 hrs) like Neverland AM from Venlo on 1035 kHz. At least all stations with a green dot in the right column are NOT on-air since they have a license.
We have also SW LPSW stations, here is the list 
https://radio-tv-nederland.nl/am/kg.html . You will hear them because they use 1 kW! Because the licenses are expensive, I think many stations will stop at the end of the year, also some professional parties have a much better DAB+ coverage now.

About my station Album AM at 846 & 1251 kHz. I use only one PWM transmitter and inverted-L antenna, 1251 kHz is ALWAYS off-air because I obtained it as an exclusive for Holland frequency. It is not so good as 846 kHz (lower frequency) so the coverage is less and especially when it is dark it is a bad frequency because of a strong station (25 kW) from Hungary, 846 kHz has interference with Radio North (3 kW) from Ireland. I use it as spare, when somebody occupies my 846 kHz legally (distance 50~60 max. power 50 W pep, 60+ km max. power 100 W pep) and has an exceptional good antenna, I will switch to 1251 kHz when I experience strong interference halfway so I am happy with my exclusive for Holland 1251 kHz!

(CRTC) CKHJ 1260 in Fredericton gets approval for major nighttime power decrease.
Bell got the go ahead today to reduce the night power at CKHJ Fredericton from 10,000 to 32 watts. Day power will remain 10,000 watts. The station currently utilizes a three tower array which will now be reduced to one tower. 1260 is now de-emphasized on the air with a 250 watt rebroadcaster on 103.5 in the nearby community of Oromocto taking on the “unofficial” originating station status.

Norway

I have seen mentioned in several radio groups, that the 1485 kHz NRK Longyearbyen transmitter has been upgraded from 1 kW to 3 kW.
This is NOT correct.
The new transmitter, which was installed in spring, is still running 1 kW, which was stated in an email received today from NRK information office.

My local WMYC AM 1580 Columbus has been running its day pattern and power all night long for the last three weeks. So, this should give DXers a chance to hear this station south of Columbus at night. I don’t see where they applied for an STA. They have a new engineer at the station.

Classic hits format per radio-locator, showing
Daytime 3200 W is almost ND:
https://radio-locator.com/cgi-bin/pat?call=WMYC&service=AM&h=D
Nighttime 290 W is broadly direxional peaking SSW, null northward,
so day pattern at night should be more helpful to north.

FCC Approves All-Digital Option for AM.
The Federal Communications Commission will allow U.S. AM radio station owners to convert their stations to all-digital HD Radio transmissions if they choose to do so.
The commission voted unanimously in favor today at its October open meeting.
Industry observers will be watching to see if any owners large or small take this step. All HD Radio receivers in the market are capable of receiving the MA3 signals; but making this switch would end analog listening on the given frequency.

Turkmenistan

Interesting information on LW 279 kHz Watan Radio:
The transmitter in Turkmenistan is working, but modulation (sound),
judging by the posts on the forums, is very rare (or very quiet).
Personally, in two years I heard modulation only three times, and then
more than a year ago.
Judging by the sound quality, somewhere in the sound channel there is
a device like a noise suppressor, whose settings have drifted away over time, and it began to completely crush not only the noise, but also the useful signal. Why the workers of the radio station for several years have not been able to find a fault and have wasted heating the air is a mystery.
The transmitter most often turns on at about 2 am UTC (5 am Kyiv time), then turns off during the day. The work schedule is irregular, but a 4-day period can be traced. It seems that the duty shifts work in a “day after three” mode, and each has its own work schedule, which is also unstable. One of the shifts often leaves the transmitter on overnight. Today is just such a night, the next – from 16 to 17 October.

I don’t know how true this is, but it may well be. I wonder why they won’t eliminate it? If there really is a squelch, then adjust, replace or remove it altogether.

United States

The Federal Communications Commission will vote this month on whether to allow AM stations in the United States to convert to all-digital HD Radio if they wish to do so.
Commission watchers have expected some action this year. Commissioner Ajit Pai announced the planned vote on his blog, calling AM revitalization “a passion of mine.”
Based on anecdotal evidence, the commission will likely approve it.
The details of the proposed report and order are expected to be public shortly. Among questions to watch for are whether all-digital AM operation would be allowed both day and night; what provision the FCC makes for a station to change its mind later; and whether the commission will waver from its stances on not allowing the use of other platforms like Digital Radio Mondiale and not allowing multicasts of an AM digital signal to be carried on translators.
