Medium wave reception through a DX Engineering NCC-2

While MW is sadly declining rapidly everywhere, it is still well populated in Spain. Typically, on any MW frequency (they are 9 kHz apart here in Europe, and 10 kKz in the US and other places) there will be several stations from the same network transmitting simultaneously.
Anyway, MW is not easy to hear during the day unless you are more or less in the target area of the transmitter. Things improve substantially after sunset. On 837 kHz we presently have four transmitters of the COPE network, from the cities of Ferrol, Las Palmas, Sevilla and Burgos, none of which is very audible in Madrid, where I am. However, by phasing two active vertical antennas, reception is possible with relative comfort even in daylight hours (it is noon as I am shooting this video). The same applies to other frequencies I am checking. The device I am using (DX Engineering NCC-2) is also an effective noise canceller, using the same phasing principle. When the NCC-2 is off, a passive long wire antenna (about 10 meters long) kicks in automatically, but those faint signals cannot generally be heard unless propagation conditions are exceptionally good for some reason).
My active vertical antennas will effectively cover any frequency from just a few kHz up to around 30 MHz, but they particularly shine on long and medium wave.
MW has already been shut down in many European countries, and in some Spanish cities. I really hope it will stay with us for a while, as it covers very large areas of Spain where FM or DAB are not yet an option.
