OTR was not received in Japan, but very well in Georgia, USA on 15.008 MHz. Signal was also good in many parts of Europe.
OTR built experimental longwire-antenna for 19 mb which was 239,5 meters long wire on ice hanged on sticks about 3 m high!! Se the photos below!
This longwire was matched 1/12 wavelegth to 19 mb to 230 degrees direction. It is not the best possible direction towards Japan, but should give back-beam to that direction!
There were similar to North America-direction (310 degrees direction) which reached USA.
