I wrote about FCD(FUNcube Dongle Pro) and the point of how to decode
Delfi-n3Xt signal by this method.


 
 1. FCD Concept (C)PA3GUO
 http://www.ne.jp/asahi/hamradio/je9pel/fundongl.htm 
 
 I link to some articles of Japanese references in that page.

 
 2. FCD Obtaining
 http://www.ne.jp/asahi/hamradio/je9pel/fundong2.htm 
 
 I described how to get FCD and install it.

 
 3. FCD How to Install

 Because there are individual differences in FCD, and adjust
 to put the appropriate values for each satellite Frequency_
 Offsets in Settings. The adjusted value was approximately
 +15kHz in V_band and +45kHz in U_band.

 
 4. HDSDR, DUDe Obtaining

 Install DUDe by setting the UserName, etc., and Satellite
 signal flows as follows. "Antenna -> FCD -> PC -> HDSDR -> DUDe"

 The sound can be demodulate perfectly and decode in MixW
 such as FM setting. Set up to Mixer in Control Panel of PC.
 And set up Input: FCD, Output: Soundcard in SDR
 and set up Input: Soundcard in DUDe software.

 
 6. How to decode Delfi-n3Xt SDR by JA0CAW

 It is a point that is fit to 2300Hz the center of the
 received signal, and spread to 4500Hz the reception band.

 
 7. Tips of LO, Tune frequency setting in HDSDR by JE1CVL
 http://blog.goo.ne.jp/je1cvl/d/20140112 
 
 Set the frequency of a few +kHz shifted slightly in LO Frequency
 because the spurious will apearein it. Set to Tune Frequency
 the reception frequency of the object. Increase or decrease as
 the left and right click for the adjustment or drag the blue band.

 LO frequency was set to a higher about 145.890MHz.
 And while dragging the blue band width as fit to an orange width
 of the satellite signal, I could decode finally in DUDe software.

 
 9. FCD + SDR# No.1
 http://wakky.asablo.jp/blog/2014/01/19/7197254
 
 As can be seen by looking at the yellow band of the received
 signal of APRS, my FCD will find that there are individual
 error of about 15kHz in V_band in this state. Therefore,
 correct by satcontral_fcd software for the satellite.

 
 10. FCD + SDR# No.2
 http://wakky.asablo.jp/blog/2014/01/19/7197305
 
 The signal was weak with two passes in today(19Jan2014) morning,
 so it was not able to decode. However, I got the feeling that
 could be decoded by SDR #. "Delfi-n3Xt + FCD + PC + SDR# + DUDe"

 
 11. FCD + SDR# No.3
 http://wakky.asablo.jp/blog/2014/01/24/7202928
 
 I was successfully decoded Delfi-n3Xt by "SDR# + DUDe".
 Run SDR# -> Set frequency in SDR#
  -> Run satcontrol_fcd -> "connect FUNcube dongle"
      -> Expert -> Frequency Offsets -> SDR# "Play"
