The Delta 1 is a double conversion receiver. The first IF is 11 to 11.5 mHz
and the second IF is 6.3 mHz.
It stands by itself in this scheme. The Tritons, Argonaut I, OMNI A+D, C,
Corsair I and II, are essentially single coversion
receivers using a 9 mHz IF. The Corsair's had an extra conversion from 9
mHz to 6.3 mHz and back
to 9 mHz for passband tuning. The OMNI V and VI also use the same scheme as
the Corsair's.
I do not know the scheme in the Delta II and Argonaut II.
The Paragon I and II , up converted to 72 mHz and then to 9 mHz, also with
the passband tuning
scheme going form 9 to 6.3 to 9.
The Pegasus, Jupiter, and RX-320 up convert to 45 mHz, then 455 kHz, then
12 kHz for DSP.
