It was definitely 10kW, a 100kW transmitter in those days was massive, and I've been in the room the HF was in. But I bow to your better knowledge of the other points.

BTW although one of the two masts that supported the MF T antenna used on 612kHz is gone, and the site is mothballed, three generations of MF transmitters remain in situ.

The original Marconi which takes up most of the main hall, the 1950s Brown-Boveri 100kW and the 1970s 2x 50kW Continental - all still there. I have photos somewhere.

Interested to know how you discerned this!

Here you go, radiation plots of a 48m half-wave dipole at heights:

Black 6m
red 12m (quarter wave)
Blue 24m (half wave)

Between the late 1930's and the 1950's, Radio Eireann were on SW regularly on their own transmitters from Athlone, officially.

The more recent broadcasts, both on 6220/5 and 58xx were official relays.

An old RTE engineer told me as far as he knew there were few, if any SW transmissions from Athlone. The 10kW transmitter was indeed installed, but it didn't last long, apparently. I've been to the site, the transmitter is long gone, but there are clues in the building as to where it was.

Thanks for the kind words - great to see conditions favouring your part of the world in the evening (our time).

FYI tx power is 250W at the moment.

Also glad you like the Beautiful Music!

Wow a numbers station on 5779 USB now, 17:30, announcing "412/33" repeatedly before commencing the usual 5-digit sequences. I've never heard a numbers station on this frequency before.

19:40, Radio Luxembourg recording, then ID "Radio 319" with email address etc.

Good quality, signal approx S6.
