Additional to the problem with the malfunction of tx/rx-switching, that we try to clear by E-mail, i have one more question about the ADF-Board:
On the PCB and in the circuit-diagram the LED is connected by a 2K-resistor to PIN 30 of the ADF4350.

In the Datasheet, the PIN 30 ist MUXOUT and i think the LED should be connected to PIN 25 - LD (Lock detect). Right ?

Hi

Work TRV2:



and in the magazine: "Swiat Radio" (Radio Word) there is an article about the TRV2 and the Oscar-100.


May I wish you a very Merry Christmas, with joy and happiness for you and your family!

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

Hi

Thank you for your kind words.
Price for ready to work set: antenna 2.4GHz (Helix or POTY) + LNB + power supply + TRV (min. 2W Out) + shipping = 319.00Euro.
The last version is 1.7

Artur,

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

Hi

The differences between the versions are small and mostly concern the values of the elements.

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.
