Hi Artur,
i just wan´t to give you a positive feedback:
My transverter is running fine and i had already my first QSO over QO-100.
Now, i have some questions:
1) Some Ham-Radio frieds of me are also interested in this TRV, but aren´t able to solder SMD and like this. Can we order ready installed Modules by you ?
2) Do you have further developed the transverter and which is the actual PCB-Revision ?
Because: when 1) is not possible, i think about to order some PCB and Cases and so on by you an give them to a company to soldering it.
Kind regards,
Michael

Artur,
I still have a set v1.2. You recommend to use it or are there too many modifications?

Hi Artur,
I'm thinking of building your transverter to add to my Eagle.
I have looked at the schematic and some questions :
- Your PTT is controlled by the incomming signal, which is passed thru an attenuator.
But in the first time - before the relais switched - the input signal from the transceiver is
feeded to the LC and the 50 R at the mixer. The relais is specified with 3ms switching time...
Have you measured the switching time of your circuit?
- You have added a DC bias to the POTY output. I think it is to activate your 20W amplifier.
Most users will not need it.
- There are no remarks on the used caps in the BOM. Most of the caps in the signal path have to be ATC types.
- Do you reach the drive level of the mixer? It is a level13 mixer.

Do you think about a next version of the Transverter ? Maybe with a little bit more output (for example 3-4W) ?
With the Helix and the 2-2,5W the signal ist one of the weekest signals at the QO100-Transponder...

I want to tune 2m from 144.5 to 145.0.
2255.5 MHz
595 MHz
Did anybody apply appropriate changes to the 2m section in the code?
...before I dig into the data sheet ....
I answer myself :-)
There is a SW for the Eval-Board... the register values are computed from output frequency.
Here are the values:
//PLL configuration
#define FREQ1 2255500 // kHz - F1 (used by default)
#define FREQ2 595000 // kHz - F2 (configure S1 = ON and S2 = OFF)
#define FREQ3 1960500 // kHz - F3 (configure S1 = OFF and S2 = ON)
#define FREQ4 300000 // kHz - F4 (configure S1 = ON and 22S2 = ON)
#define ADF4351_INT_F1 90
#define ADF4351_FRAC_F1 11
#define ADF4351_MODULUS_F1 50
#define ADF4351_INT_F2 95
#define ADF4351_FRAC_F2 1
#define ADF4351_MODULUS_F2 5
Tnx, Frank
