Construction Interface SSTV / PSK / RTTY for Tablet (Android) by DD7LP.
Interface is excellent for all who value mobility.

Schematic diagram of the Interface.

The red and blue indicates the elements, which I mentioned to the interface work with the Samsung Galaxy Tab II and GoClever Elipso 71 and radio K-PO DX5000.

  3. Hello OM Wojtek.
    I have built this interface with the original PCB as well,
    but I could not get it to work proberly.

    When pushing Start TX button the radio goes to TX, but when pushing Stop TX the radio stays in TX
    and did not come back to RX.

    I noticed you have made changes to the schematic, don't know if this could be a solution for my problem.

    Do you have any ideas?

  4. I had the same problem, so I swapped the two capacitors (C5 and C6) in the circuit diagram for the smaller ones. With 100uF to 4.7uF. The smaller the capacitor, the faster interface switches to RX.

  5. Thank you Wojtek, you made my day.
    Experimented with 2.2uF also, this makes a huge improvement.
