Finally heard Western Australia on MW! First spotted by Tore Johnny Bråtveit on this interesting opening on October 13, it had decent signal levels on top of the hour, mixing with a Thai station. Email response today. Wagin is located inland, near Perth.
The 50 degrees beverage antenna used is nowhere near suitable for hearing this part of Australia. One directed at 80-90 degrees would have been a lot more efficient. So we're planning a temporary beverage at a better direction next autumn. And Tasmania is next!
