Here is the thing we need to determine the "Fiq" We know we have the direct conversion receiver required. Quoting the WSPR I/Q set up instructions"
"Depending on how you have wired your SoftRock, you may or may not need to check Reverse Rx I,Q or Reverse Tx I,Q. Mine does not need these boxes checked. The parameter Fiq (Hz) determines the frequency offset between Dial frequency specified on the WSPR main screen and the frequency (times 1/4) of the SoftRock’s Si570 programmable oscillator. The default value for Fiq is 12000 Hz; this puts the 200 Hz WSPR band 12 kHz above mid-band. For example, when operating on the 30 m band you might set Dial frequency = 10.1387 MHz and Fiq = 12000 Hz. These settings result in a commanded Si570 frequency of (10.138700–0.012000) × 4 = 40.506800 MHz." We need to know this for the Flex-1500 and the other Flex-XXXX radios. Sorry I am maths challenged and getting worse.
