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.
