Hello OMs!
I have a problem with the interface between my android device and the radio UV-5R. I assembled a circuit of two resistors and one capacitor (pic in 7plus in TECH.WW) and it works: the radio station from the vox switches to transmission and transmits packets, and the received packets are transferred to the APRSdroid program (as WoAD) and everything is fine. But! After transmitting the packet, the radio station remains in transmission mode for a fraction of a second, although nothing is transmitted on the air. Whether this is a feature of the vox UV-5R, or whether there is some kind of voltage at the output of the smartphone that causes such an effect, I cannot understand. Has anyone encountered something similar?
And is there a solution? I would be glad for advice, diagrams, what can be changed or corrected.
73!

1200 baud it's greater, than zero bits per second :)
