Some more info on the subject.
I had set my LO to 183.700 so the SIW signal would fall at ~1500khz(-15)
as would be expected for WSPR and OPERA 32, SIW listed as 185.185khz on Monday
Decoded signal recieved at 1483 offset from carrier, LO, just hours after focusing
on recieving SIW, Also listened for OPERA 32 signal but nothing decoded there
I am also starting to operate on LOWFER at 185.970khz on some late evenings MST. I am presently using a horizontal 15m wire antenna at 100mW. I am alternating between QRSS10 and FST4W300 transmissions. To listeners I would appear something like the following using FST4W300.
