In the last three months of last year I received 11 beacons from the Czech Republic. My report to ANS remained unanswered. Arvid Husdal was so kind to provide me with the email address of Miroslav Najman, OK1DUB, who works at ANS as Radiocommunications Systems Adminstrator.

Within a day Mr. Najman sent me an email. 7 of the 11 beacons in my report were military and outside ANS responsibility (see below). But he could confirm my reception of 4 of them:

NDB L, Karlovy Vary,  365 kHz
NDB L, Prague, 372 kHz
NDB B, Brno, 429 kHz,
NDB R, Ostrava, 534 kHz

The beacons are Thales NDB 436, operating on 50 Watts power. In addition to the technical info I received 4 nice pictures of the transmitter containers and antennas.

NDB L-365 Karlovy Vary
NDB L-372 Prague
NDB B-429 Brno
NDB R-534 Ostrava

The following beacons are owned by the military:
CF-345.5 and C-715 for Caslav Airbase
PK-432 and P-888 for Pardubice Airport (shared mil/civil)
K-438 for Praha-Kbely Airbase
LA-514.5 and XU-563 for Namest nad Oslavou Airbase
