Unter manchen anderen Aktivitäten hat Jamie doch auch mal
'was in Somalia gemacht'.

Und das bewundernswert, an einigen Ecken dieser Radio-Welt, für kleines
Geld.

der auch Voice of Freedom 10 kW Anlagen in Korea aufbaute.

Im Febr 2010:
VANUATU   As of Wednesday, Febr 24th, here is what we accomplished. 5055
kHz is on at about 3500 watts, and 3945 kHz is on at 7000 watts. But, due
to the unstable A.C. power infrastructure, I had to design the protection
circuits to be very sensitive. The systems will "fold-back" the
transmitters to 2000 watts if it senses any kind of spike or surge in the
A.C. power feeds.

Senderbauer Jamie Labadia wollte am 18. April 2010 nach Georgetown
fliegen, um den neuen Kurzwellensender des National Communications Network
nachzuarbeiten. Bekanntlich hatte man bei ihm einen 10 kW-Sender fuer
5290[?] kHz bestellt und dabei eine Mischung der eigentlich vorgesehen
Frequenzen 3290 kHz nachts und 5950 kHz tagsueber produziert. Labadia
wollte beide Frequenzen bis spaetestens Ende des Monats in Betrieb sehen.

BOLIVIA   I am building a 5 kilowatt transmitter and antenna system for
Radio Juan XXIII. It will be on 6055 kHz. It is the first prototype with
the new MOSFETS from Philips (BLF-278). It will consist of ten, 500 watt
"drawers", with a ferrite based hybrid combiner. I am going to build them
a LAZY H style antenna array. It will be four 5/8th wave elements, two
over two, beaming broadside North / South. It should give about 8dB gain,
making the effective radiated power approximately 30 to 40 kW with a major
lobe going into North America. I believe we should be testing near the
middle of February.

Techniker der Stimme Guyanas haben den Tropenbandsender auf 3290 kHz gestern
reaktiviert, vorerst wird mit 400 Watt gesendet.

Hi Glenn, I have the Voice of Guyana on the air at, don't laugh, 400 watts.
3.290 MHz is the freq. I am going to repair a few more amplifiers and get
them up to about a kilowatt for now. Have to reconfigure the combiner
though. The antenna is in rough shape, but surprisingly being heard well
down into interior Guyana, which is the main purpose. (On a portable no
less!!) I'll keep you posted on how it's going. It's 80 degrees and very
"tropical" here now. Best Regards (Jamie Labadia, 0147 UT Feb 2, DX

Checking around 0300 UT Feb 2, I do have a JBA carrier on 3290 - could be
it. Will it be on all-night? (Glenn Hauser, OK, DX LISTENING DIGEST)
