Seems to work well with AndFlmsg, Tx/Rx, connecting an Android phone with a BTECH UV5X3. A lower VOX setting, level “4” seemed ok. Level “9” had signal interruption issues.
Amadeus Mozaricus da Silva Penteado –
The cable is fantastic, but the price is ludicrous for Africans, South Americans, and Central Americans to be able to buy it. Please, consider making the price at least 6 USD cheaper. That would be a good price, a fair price for a cable, taking into consideration the different monetary realities worldwide.
JC –
Great Cable.
