Funny your last post Glenn. I did the exact same thing as you several evenings ago. I went hunting for a remote kiwi SDR in or nearby Romania to see if I could have a listen to radio Romania. What I found was very interesting.I found a kiwi SDR right in Romania. It was about 9-10 PM eastern time here and well into the wee hours in Romania. This particular SDR had good LF ears and I was able to easily listen to Morocco on 171 kHz and BBC on 198 kHz. But on 153 kHz all I saw was a very light trace of a carrier from what I am presuming to be Algeria. But for all practical purposes 153 kHz had zip on it. It appears Romania on 153 kHz was not transmitting because surely it would have been slamming and ringing the bells off the SDR with a massive signal.
Several days prior to this I sent out several e-mails to their listed addresses in English and in Romanian asking them to confirm their existence on 153 kHz LW but I have not heard anything back. I was able to listen to their programing via the web and they even transmit in English, for an hour, but this was a simulcast of what they were broadcasting on their HF frequencies.
I am going to go back to that remote kiwi SDR and have another listen for 153 kHz as it would be currently in their daylight. Maybe they only transmit during the day? I don't know the full story yet but as I learn more I will report back here. 73 Gedas W8BYA
