Below is a summary of various SW and MW transmitter closures which are are mostly due to take effect from 1 January. This is summarised from reports which will be in January Communication (DX News and Medium Wave Report):
Voice of Croatia is dropping SW, but continuing on MW 1134 kHz
Voice of Russia is dropping MW relays on 630 (Königslutter/Schepau), 1323 (Wachenbrunn), and 1431 (Dresden Wilsdruff). Only remaining German relay freq is 693 kHz (Berlin Zehlendorf)
MR6 Régió Rádió closed on 22 December. A new station Radio Danko is using former MR6 frequencies of 1116, 1251, 1350 kHz with Hungarian and gipsy folk music and rural news (similar to Antena Satelor in Romania).
NRK Rost 675 kHz is closing - a planned closure announced some time ago.
-St Petersburg SW/MW site is closing (including MW 1494 kHz)
-Samara SW site is also reported to be closing.
-Mayak is closing on MW/LW throughout Russia
-Voice of Russia is reducing some of its SW/MW output across its
language services following budget cuts.
Radio St Helena (MW 1548 kHz) closed on Christmas Day. It will be replaced by St Helena Broadcasting Corp on FM only.
CVC 1Africa is dropping SW. (Had been scheduled on 13590 at 0600-2200 but 13590 has not been heard for several days, I suspect it has already been switched off)
The above is fairly grim news for short wave, though on the positive side there have been a couple of stations reactivating on SW recently - Radio Uganda on 4976 kHz and Bangladesh reactivated with a new SW transmitter earlier this year.
