As I came into the room and picked up the R-911 Receiver and tuned to
WFAN 660kHz... there is Morse Code in the direction of SW or NE from
location FN31nl. An obvious recheck in order with the PL-310 and 1kHz
Bandwidth confirms maximum signal on 668 kHz. The general bandwith of
QRM is wide on the cheap set perhaps +/- 10kHz. On the PL-310 DSP set
standard BW of 3kHz indicaates RX up to 680 kHz. 670kHz is still quiet
as Chicago hasn't kicked in yet.
Time 2345UT (1845 EST) and still on-going with brief pauses. Now drifting up to 669kHz max RX.
