Tincap, Armenia would be great DX even at 1MW! Last night in my area of No. Illinois there was too much static to make listening for 'split channels' worthwhile.
About what time UTC are you hearing the Euros coming in? I have noticed that the hets start about an hour or so after my local sunset (approximately 0045 UTC) but before local midnight (0600 UTC) the heterodynes are gone. The only confirmed audio has been Croatia on 1134, and that only lasted about 15-30 minutes a few nights (around 0130-0200 UTC), and sometimes audio would reappear later in the evening, but not for as long. 693 gave me audio very briefly for less than 5 minutes about 3-4 nights ago, but I couldn't definitely confirm what it was, though I suspected the BBC/UK. So despite the theoretical window of reception over TA distances being a complete path of darkness, in reality there are only narrow intervals of time within a all-darkness path that the signal strength is sufficient for audio to be intelligible. With a ferrite loop or an approximately 100' long wire antenna, it's not going to happen often, being in the Midwest US. I really need to consider at least a box loop or an amplified vertical... Beverage antenna... well, I need to ask a farmer if I could use his field since I live in a suburb...
