I too have a similar issue as Mike. Mine is a 1070khz 25Kw station 3 miles away, images of it showing up all over the dial on my brand new 5000A using PwrSDR 1.12 (the version it shipped with). Therefore I too am looking for a RX1/2/loop solution. If there¹s any others with the similar issues, who¹ve found a solution, it would be appreciated if you shared it.
I don¹t get this issue with my FT-9000, IC746 or JST-245 on the same antenna. Only my Flex 5000A w/ATU has thee AM BC signal images up & down the dial... Its my only complaint about the radio¹s RX. Thanks!

I have IMD/spurs/carriers all the way up from 160M to past 20M. The signal strength of the AM 640kc station is -3dbm on the flex meter and I have crud all over hell's half acre up thru the bands...most are just above the QRN, but sometimes not ;-)This AM powerhouse always mixes with another station beating together on frequencies that show up across the bands. I purchased a KIWA BCB reject filter and put it in the RX1/2 in/out loop and use the antenna selection option to put this inline and it definitely knocks down the 640kc AM >70db when the flex is in GEN mode tuned to 640kc. The problem is that when the BCB filter is inline with RX1 loop, I have major intermod all over the bands...on 20M I heard CHU this afternoon at 14.030, +/- propagation and AM carriers all over the spectrum, some are S9+10 in DSB mode on 20M. If I take the KIWA BCB reject filter and put it inline with the antenna in any ANT1/2/3 port life is good...all the crud is gone, but I can't TX with the KIWA BCB filter. Anyone care to figure this one out? I know W9NQN TX/RX filters are an option, but a $60 RX only should have worked IMHO. Enjoy what's left of our holiday weekend!
