You also want to experiment with the LNA Gain and Mixer Gain. I set the LNA Gain ON and the Mixer Gain OFF. Again that is needed to get a low noise floor.

Hi Steve,
Yes, make this number 4!
4-I find under Windows 7 with the FCDP+ a Recording Device volume setting of "3" gives me a decent noise floor (between -75 and -100) on FoxTelem. Getting the noise floor level down to a reasonable level is important.

Mark,
Didn¹t you also experiment with the Windows audio input setting?
From memory, I think it defaults to 100 under Windows 10 and you found it worked better at a lower value, like 4-5?

Hi Bob,
I am going to copy AMSAT-BB because this will help some others I hope!
Here is what works well for me and the FuncubeDongle Pro + and FoxTelem 1.02b:
1-On main screen, "Check" Track Doppler and Find Signal; I use default values in the boxes (15.0dB, 6.0dB)
2-Under the Spacecraft Menu, go to both Fox-1Cliff and Fox-1D parameter screens and "Uncheck" Track when Find Signal Enabled
3-Under the Spacecraft Menu, go to Fox-1A and "Check" Track when Find Signal Enabled; I use Downlink=145979, Lower Freq. Bound=145973, Upper Freq. Bound=145985
THAT should get your good, fast lock on the Fox-1A signal. Works well here setup like that.
Let me know how you make out!

Hi Mark. Early on with Fox1A "somebody" emailed me about trimming down the FOX1A_fm.dat a bit and limiting the scan range for FoxTelem to find the beacon early on in an orbit.
I just beeefwittedly overwrote some data files when updating the FoxTelem program. Thus I now have numerous "Tabs" of Fox1-1C and H and so forth.
Were you the one who suggested the trim-down ?
Otherwise, any ideas on shaping that Dat file to make it find the
signal
earlier and stay locked on?
Mine "was" working just fine with whatever I'd put in the folder. Or maybe the stock program as it is now written is just fine.
