did you also increase the transponder bandwidth a little bit?
-
hi DB8TF ,
what brand/type of OCXO are you using?
-
I have a question:
what is the best value for LDPC?
and more over: if the LDPC value is bad who is the culprit? the transmitted signal that might be "distorted" or the receiving system?

Display MoreWould the Tiny Spectrum Analyser work with the Minitiouner-Express?
A side question, is there a way to change the OSCAR 100 presets in the V0.9 version for whenever the beacon is changed?
Thanks very much for your software.
Adrian
hi Adrian G8UGD
if you mean to change the preset center frequency of the beacon memorized in the "Q-beacon" button you must edit the "minitiouneConfig.ini" file.
look for the button definition:
;.......................................
Freq1Value=10492500
; Standard Satellite LNB offset
Freq2Offset=-09749929
Freq2Doppler=no
Freq2Text=Q-beacon
Freq2Fplug=A
Freq2LNBvoltage=18
Freq2_22kHz=Off
;.......................................
and change the "Freq1Value=" accordingly.
the Symbol Rate must than be changed manually unsless you modify also the value on the 1st SR button:
;=====================================================================
; programmation des boutons de preset Symbol Rate
[SRPresetButtons]
;=====================================================================
; valeur en kSymbols / value in kSymbols
SR1Value=2000
; inscription sur le bouton
SR1Text=SR2000

is LEILA a Pluto?
yes! Leila is a dog...watch...

so George SV1BDS my mistake!
I was using the datasheet for the SKY65135_31...
-
yes, but driver and pre-driver get 3,3V instead of 5V.
all measurements on the datasheet are taken with VCC1, 2 and 3 at 5V.

sorry George SV1BDS but I cannot recover the mail I sent you!!!
if you still have it you can publish it here.

George SV1BDS :
problem solved!
the supplier answered my question:
>>>
Hello, sorry for not responding in time because of our Spring Festival holiday.
EN is the switch of the amplifier, the enabled state: 1.2-5v, the non-enabled state: 0-0.4v
Best regards,
skyline
>>>
it seems that he is competent!
maybe later I will ask infos on that "5 legged" IC...
-
I tried to follow the PCB strip from the EN pad but, as far as I can see, it goes to an unknown device marked DH=U0G (it's a 5 pin IC...).
there is also a voltage stabilizer IC AMS1117 which delivers 3,3V to pin 16 and 15 of the 65135...

Hi, anyone try this 1W amplifier ?
hi George SV1BDS !
I just received the amplifier and would like to try it...but I feel like a monkey (or a donkey...as you prefer) because I don't know what to do with the two pins marked "EN" and "OUT"!!!
(the OUT pin could be the DC output of the internal detector...)

nice job ra3apw !
what is the active device you use in the 20 watt amplifier?
-
hi Manfred DK5FA !
what kind of connector (the double female) is that?
and, more over: where did you find it???
I need some for my Siemens W30861-Q4160-X-5 PA!
thanks!

thanks G0MJW !
I hoped it was easier!!!

I found the phase noise was poor on my Octagon quad with a 24 MHz reference (normally 25MHz) so I investigated good frequencies. Setting a 9.5 GHz LO with a 24.35897436 MHz reference worked well. The maths is easier too. Now I can use an Octagon SF8008 to receive DATV as the IF is above 950 MHz.
Mike
hi Mike,
can you tell me how you measured the phase noise of the LNB?
not to "pollute" this thread you might open a new one or write to me directly.
thanks!!!
