How to turn an EWE or BOG into a dual feed arrangement

Need to remotely turn/off the termination R then look here

What's below 150kHz ?

Worlwide map of all MW transmitters with ERP above:
 - 2000 Watt   (8600 entries, in 2017)
 -   100 Watt
  (15000 entries in 2017)

compare that against earlier times:
 - 2000 Watt
  (9100 entries, in 2012)

The circle size represent the ERP (not the coverage range).
Hold the cursor above a circle to see its data. (based on MWLIST
Program-Names are not included.
The map shows nicley where the populated areas are in Asia / Africa / Amercias

Warning: These huge amount of entries create a heavy burden on the browser and will slow it down. Better first try the 2 kW variant.

This UK Absolute-Radio Tx map shows where the low power repeaters are. Many sit within the intersection of several main stations and most likely have reception problems on 1215 kHz despite the use of a synchronized network.
