NDBs on the ArcticSDR? There are actually NDBs in Ukraine and Russia that are above 530 khz. I've heard some in the 700-780khz area. Not bleed whatsoever.
Last night was a crazy Asian morning on the receiver! First check was 756 with at least three CNR-1's echoing from China, I'm guessing Harbin is the strongest. 1188 had JOKP Kitami // 594, NHK1. Strong Yanbian in KK on 1205.96. 1332 JOSF Nagoya (commercial Japanese) in well. 1368 had an UNID CC station that wasn't CNR. The strongest is 10KW Jixi RGD, but I couldn't find a stream. 558 had JJ underneath a co-channel, JOCR Kobe (commercial). And over at 1395khz was a PARALLEL JJ! Asiawaves lists a 1KW relay, JOCE Toyooka. Fantastic! 1287 JOHR Sapporo was strong with HBC, Japanese commercial station; and a // on 1404 was JOQL Kushiro. S9+ signal on 1440 JOWF with a USA cochannel. Speaking of USA, 1470 WMBD Peoria was in well with an ID into Coast to Coast.
819 had KCBS in Pyongyang. Sounding like I was in North Korea itself, S9+20 with the usual odd music. One notch over at 820, and it was KCBF Fairbanks AK (ESPN). Final log, 1503 JOUK Akita // 594, NHK1. I heard very little from EU, just Asia wall-to-wall and some USA/Canada.
