RTE Ireland : its historic lack of presence on SW has always been puzzling
to me ...
RTE, by my view of the way history should have happened -- would have had
the following transmission systems:
1. 2 x HRS 8 / 4 / 1
-- aimed at the US and 'Southern' Canada and Latin America
-- installed mid 1980s

1. VOA is clearly a state broadcaster, beyond question.

State broadcasters : QSLs part of domenstrating state power ...
There is no reason why a state broadcaster like VOA or BBC World Service
[high end, 12000 kw transmission power] or Radio Australia, RFI or RNZI (100
kw) should not provide QSLs.
Verifing reception is part of a state broadcaster's re

It is my view that Slovakia should upgrade its SW transmitters to the ALLISS
system (a rotatable HRS 4/4/1 antenna system), but using cheaper RIZ
(riz.hr) transmitters.
Telefunken or Thales transmitters are probably too costly (and perhaps
complex) for the nation's needs.

I have always been of the opinion that CBU 690 should be at 50 kW, day or
night.
CBU fills a role similar to KFBK 1530 and KGO 810 (both @ 50 kW), but not
during nighttime hours when it is 5 kW.
I assume that CBU is still running with a tube transmitter, as I don't
