It looks like the Mongolian Longwave stations may still be with us. According to this person from Finland each was heard this April. Here is a quote:Remaining Mongolian LWBC Stations and Frequencies [164, 209 and 227 kHz / Ed] heard here in Finland with interval signal on Friday 17th signing on at 2200 with interval signal on all frequencies, 227 kHz was the strongest. Probably for the last time in spring due to daylight, next possibility will be in September.

Mauno Ritola to Longwaveradiolistening iog (2026-04-19)
I have listened in for days on various WebSDR's and not found a trace of them. At the right time too! I found a hint that their minister was considering what to do with them. Which means they will shut them down. One transmitter is a modern unit. The rest were built by Russians in the 60's. I have searched the internet high and low and found little discussion of their fate. They are keeping it a secret. The Best time to search for them would be at 2200 UTC on a neighboring SDR. There are not many that have a quality LF signal. The person mentioned above seemed to have good signals on their SDR but I saw no Mongolian Stations.
