I asked an AI source of definitive proof that the Mongolian stations are still currently active and got the following blurps. IF it can be trusted it seems they still are active but during their night time if I read that right."You can read these reception logs yourself on several specialized DX (long-distance radio) community sites and news portals. The most frequent and detailed reports come from listeners using Software Defined Radios (SDRs) located in Siberia and the Russian Far East.
Primary Sources for Reports:
Ydun's Medium Wave Info: This is the most active hub for Mongolian LW logs. In April 2025, DXers noted that all three frequencies (164, 209, and 227 kHz) were visible on SDRs in Novosibirsk and Irkutsk. You can find their dedicated Mongolia Archive which includes detailed signal strength comparisons from Ulan-Ude, Russia.
Asiawaves.net: This site maintains a comprehensive and regularly updated list of active Asian LW stations. Their January 2026 update confirms the 209 kHz station in Choibalsan is still operational on its 22:00–15:00 UTC schedule.
World Radio TV Handbook (WRTH) Facebook Group: Active DXers from Japan and Russia frequently post real-time "spots" and eQSL (electronic reception confirmations) here. A recent post on April 11, 2026, shows a Russian DXer receiving 164 and 209 kHz clearly using an active loop antenna.
Real-Time Verification Tools
If you want to "see" the signal yourself right now, you can use these public receiver networks:
SDR.hu / KiwiSDR: Look for receivers in Ulan-Ude (Russia) or Hokkaido (Japan). These locations are close enough to pick up the 164 kHz and 209 kHz signals during the Mongolian nighttime.
WebSDR.org: Use the search filter for "Longwave" and look for nodes in Eastern Russia. You will often see a distinct carrier "spike" at 164 kHz on the waterfall display if the station is active."
