Hi all:

Just for kicks, ( and pleasant surprises ), I set the IF bandwidth on my TS450S to 12 KHz; curious to
see if it really would receive that wide, AND, could I see 6 lowFER stations in a 7.2 Khz Bandwidth.
The SpecLab Filter Control Window showed visible audio response to 10.5 KHz.
I was pleasantly rewarded with results. The target beacons were; JH, WM, SIW, TAG, KE, and EAR.
*** If there are other eastern lowFER's on the air, I'm not aware of them. ***
The Viewer Softwares required higher Audio Sampling rates to see the Higher Audio Frequencies.
Monday night ( 23rd ) the static was 5 dB over S-9 but I still saw bits and pieces of JH, WM, and EAR.
Tuesday night ( 24th ) the static was very low, and propagation was OK, but not great. Results were much better.
*** KE is Off Air for TX rebuild, and Propagation just wasn't good enough to pull out TAG. ***
The radio dial is at 181.610 KHz - USB
JH - 181.818 KHz is at 200 Hz using Argo
WM and SIW - 185.300 KHz is at 3690 Hz using SpecLab
SIW - 185.185 KHz is at 3575 Hz using WSPR-X ( WSPR15 ) BFO at 3455 Hz
TAG - 185800 KHz is at 4190 Hz using WOLF10
KE - 187.304 KHz is at 5690 Hz using Spectran
EAR - 188.830 KHz is at 7220 Hz using Spectran
