Last evening around 2300 LT, 783 KHz Fujian, China noted stronger than recent evenings.
Tuned to 909 KHz, and was surprised to hear Fujian, China back on air.
837 KHz Fujian also received, but nil on 549, and 684 KHz.
909 KHz was presumably temporarily off air, or greatly reduced TX power.

Glad to hear that 909kHz China is back on the air.

In recent months, China has enforced harsh lockdowns to avoid the spread of COVID. I am wondering if this could have affected some of the radio stations? When keeping radio station staff locked down for periods of time, some stations may have had to temporally go off the air.
.Just a thought anyway.

Noratus.
Here is a list of the names and the power of the transmitter types:
https://vk.com/topic-22444240_25525333?offset=last&scroll=1

Here are many photos of these antennas.
http://www.radio-int.am/?p=photos&l=eng

There is also a huge 8 mast ARRT antenna (Quadrat with reflector IIRC). 2 unidirectional ARRT (different type, cage antenna isn’t the same) and a “new” 6 mast antenna (maybe for TWR?).
A small one (I assume MW, maybe 100 kW?) is located there:
40.41396592656742, 45.20675781349275
The shortwave stuff looks like the common types of curtain antennas.

Also have a look at:
http://www.arradio.am/
It shows various pictures of the antennas, including the 8 mast ARRT, and the 6 mast MW antenna with uncommon wires: http://www.arradio.am/images/ar3.jpg

Are these feeder lines or toploads etc.?

For those interested. List of transmitters and antenna systems of Noratus Radio Center, Armenia.
The center was founded in 1965. Carries out terrestrial rebroadcasting by powerful radio facilities. Pay attention to transmitters. Almost everything is Soviet developments.
Shortwave transmitters type: Condor, Bob 2, Thunder
Medium wave: Boreas (by the way, not often found now)
On medium waves, the information is clearly not all. There are many times more antenna systems, as well as transmitters.
In the arsenal of the center there is a directional antenna system of the medium wave range – Bolshaya Zarya (a chain of towers)
The center goes on the air according to the schedule at the following frequencies:
864 kHz, 1350 kHz, 1377 kHz, 1395 kHz
Previously used frequencies:
234 kHz and 1314 kHz
Until April 1, 2014, Voice of Russia was relayed from here http://www.radio-int.am/rus.html

Suddenly, who wants to tell.
The cost of an hourly broadcast on medium waves with a power of 500 kW is $ 250 (23,000 rubles at the exchange rate).

RUS-DX items July 23 via WOR iog (2023-07-23)

That list is incomplete also for shortwave, earlier research indicated that four 100 kW transmitters had been installed there as one batch, the other two ones under the unsurprising numbers RV-573 and RV-574. https://www.swcountry.be/arm.html

(What’s quoted in the column “type number” are designators of specifications rather than model. A 1000 kW transmitter for both LW and MW would likewise be a PDSV-1000 and so on.)

But look at line 7: “nautell” (sic). I assume it runs on 1377 kHz, since this frequency appears to be used by Trans World Radio exclusively, or do I overlook something? Last year they asked for donations related to Iran programming, and it appeared that the idea was to add another new transmitter. Back then they also mentioned increasing the airtime to up to six hours a day, but so far it are still the established 90 minutes, 1700-1830 UTC on 1377 kHz. (No shortwave anymore, already for a good number of years, also for this – in past times the transmitters in Albania were used for that.)

Irish national broadcaster RTE was observed on Saturday 22 July with its Irish-language service Radio Na Gaeltachta with a strong but somewhat under-modulated signal on 1188kHz. The following day modulation seemed normal but the frequency carried Irish commercial broadcaster Today FM. These [presumably] “unofficial” relays were monitored on a web SDR situated in Scullibeen, NW Ireland, and were untraced on other Irish web SDRs.

“BBC Radio 4 Longwave is set to close in 2024 – although programmes like The Shipping Forecast will still be available on other channels. But what does the change to longwave mean for analogue listeners?” Presumably a future Feedback programme is planning to discuss this soon (it’s scheduled Fridays at 16.30 BST, repeated Sundays at 20.00 BST on BBC R4).

Studio equipment from Radio Caroline’s former pirate radio ship Ross Revenge will feature in an episode of a new TV show called Retro Electro Workshop on the Yesterday channel next week.
The ten-part series about the dying art of repairing electronics is fronted by super-fixer Rob Howard.

In the show he and his team find, fix, restore and revive ‘anything old with a plug on it’.
In the episode to be aired on Tuesday 25 July at 9pm, Rob goes to sea to restore a vintage broadcast studio on the Ross Revenge, which is moored on the Blackwater Estuary in Essex. The studio is equipped with a valve mixing desk, record decks and magnetic tape cart machines.

The equipment in this studio was loaned to Working Title film company for the 2008 Richard Curtis film ‘The Boat That Rocked’, which pays homage to the 60s Radio Caroline.
The vintage ship studio still gets used occasionally during monthly offshore broadcasts.

“Presenters sometimes like to access the ship’s well-stocked vinyl library, keeping alive another rare art of placing pick-up arms precisely on vinyl albums while playing jingles and promotions on hand-loaded, continuous reel tape machines,” said Radio Caroline station manager Peter Moore.

The episode featuring Radio Caroline will also be available after broadcast on UK TV Play on demand.

RTE shows contempt for ageing Irish Diaspora by ending long-wave service
(letter to the editor)
https://www.independent.ie/opinion/letters/letters-rte-shows-contempt-for-ageing-irish-diaspora-by-ending-long-wave-service/a611588724.html

Irish Independent
Friday, July 14, 2023, page 23

“RTE discontinued long-wave (LW) radio transmissions last April on the    grounds of the cost incurred in maintaining the LW transmitter.
This cost just over EUR200,000 a year, mainly to cover the cost of electricity.
The main users of the LW service in the UK were the elderly Irish men and women who left Ireland in the mass emigrations of the second half of the 20th century.
Many of this group depended on LW RTE as an important emotional and social link with Ireland. Internet radio was not an appropriate substitute for this cohort.
These were the people who provided a vital economic lifeline for parents and siblings by virtue of their monthly remittances from the UK, and who by emigrating reduced the financial burden on the State   itself.
The decision to end LW, given with a cowardly two-week notice to prevent organised debate on the issue, perfectly illustrates the dismissive contempt that the “ivory tower” RTE management has held for the needs of Ireland’s elderly overseas citizens to maintain contact with the land of their birth.
In comparison with the millions squandered on ‘talent’, failed musicals, entertainment, meals and flipflops, how little it would have cost to maintain the LW service for another 10 or 15 years for the benefit of the aging Irish Diaspora.
Christopher Greenhalgh Bearsden, Glasgow”
