Split my converter output with a homebrew 50 ohm 2 port divider and was hearing LW BCs on 162, 171, 183 and 189 kHz around 0445Z while copying Stefan

on 136.172 with a second IF radio....

BN73 core 9 Turn Input, 6 Turn bifilar output, 25 ohm CT on bifilar to gnd.....

Nice 3dB split at 3.5 ~4.0 MHz with 20 dB port isolation.....


Made the divider enclosure from a surplus video corrector rack panel header....bandsaws are great tools....
