Re: Okuma Okinawa/Poro/Erching/Coro-VEN/ARS/YUG beasts:
JAPAN/PHILIPPINES [Ryukyu Isls] BTW - is it known what ever happened to
the megawatt unit on Okinawa that used to operate on 1180/1178 kHz ?
(Noel Green-UK, BC-DX Dec 24, 2002y)
Scrapped I guess? At least I understand that it was a beast of the same
design than the 173 kHz rig at Erching, finally used by DLF on 209 before
the new Aholming site took over.

I assume, the remaining parts were used as spare parts at the Poro-PHL
site 1140/1143 kHz - [Ban Pachi-THA 1580/1575 came on air later in
1966/1967 and may of different design], these units was of a similar type
as Erching and Okinawa beasts. Poro came on air already in the Fifties,
maybe you can check the 1954 to 1957 WRTH's?? (wb, Dec 2002y)
My earliest book is the 1953 edition, and there is no listing for any of
the 1000 kW txs in that one. In the PHL there was a 50 kW tx (Manila-A)
operating on 920 KHz (326 metres) located at "The Voice of America Relay
Base, Manila" plus SW of 7.5/50 kW. It operated in Amoy, Cantonese,
English, Mandarin & Swatow. In the VOA listings there is also an outlet on
447 [metres I guess] for Mandarin at 1500-1530 & 2200-2230, but I can't
find where that came from.
But in the 1954 edition three 1000 kW are listed - the one in Germany
listed as Munich-C 173 kc/s 1734 m 1000 kW and on air at 1615-2330. (1196
was Munich-A by the way - and also listed at Munich 10 kW SW was R
Liberation in various Russian dialects).
The others were listed as RYUKYU ISLANDS Voice of America Relay Base and
MW Okinawa 1180 kc/s 254 m 1000 kW operating 0930-1530 plus SW 35 kW
operating same times - and in the PHL, the VoA Relay Base, San Fernando -
Northern Luzon, appears. This has Philippines-B 1140 kc/s 263 m 1000 kW
operating 1000-1530 plus SW 35 kW on air 0900-1530.
So they were obviously put on air some time in 1953. I would also guess -
like Wolfie - that when Okinawa closed, the dismantled units were used as
spares. There is a photograph in one of the WRTH's that I seem to remember
showed these 1000 kW txs as only one unit - ie not 2 X 500 - in a rather
large cabinet ! [Yes, also German PTT engineers told the "Funkschau"
magazine in 1979, that the 500 kW tx circuits couldn't separate in total,
wb] Whether capable of operating differently I don't know. I heard both of
the PHL ones (before they moved to 9 kHz spacing) and Okinawa. But don't
remember anything of the 447 outlet.

re: Continental 1000 kW beasts.
The informations regarding the Continental "beasts" is very interesting.
VoA 1000 / 500 kW beasts again. I've got a copy of ROI Vienna's
INTERMEDIA/DX TELEGRAM progrs of 2001&2002, put all as farewell present on
a CD by presenter Wolf Harranth [also of the 1941 ageclass], who resigned
from ORF DX Progrs duty recently in Oct 2002.
And subsequently I had a look to the DX Progr lists on the WRTH's of 1969-
1971.
1971 p 132, the Continental 1000 kW beast advert is print-out,
and declared the first beast ever built for Munich-C Erching site on LW
173 in summer 1953. Used for VoA and even Deutschlandfunk progrs by Ge PTT
til 1979.
