Walt, N3PLA, took the diagram to the next level
and added the Dual PTT and a TRRS jack.
Great job, Walt.
Dual PTT Switch Baofeng UV-82 series
A standard single button remote spkr/micr will select
Display B (the bottom display) when keyed.
There are earpiece/microphones available that incorporate two PTT buttons. The
wiring configuration for these is shown below.
Connecting contacts X to A will key the transmit channel in the upper display.
Connecting X to B will key the lower channel.
Recently, a Dual PTT Spkr/Micr was put
on the market for the UV82 series. The top button selects display A,
the side button selects display B. (Amazon

Keep in mind, this microphone was designed for radios having the Dual
PTT option as part of the radio. Adding the extra switch to the
microphone will Not add the function to your radio.
PROGRAMMING CABLES for Anytone, Kenwood, Wouxun, Baofeng

The RXD line from the module goes to the
sleeve of the 3.5MM plug. The TXD line from the module goes to the
ring of the 2.5MM
plug. The GND line from the module goes to the sleeve of the 2.5MM plug.
There are several variations of CP2102 boards available.
The pin location and labels may vary.
Below are two examples.

Note: Some boards have the TXD and RXD pin labels reversed.
If your cable does not work, switch the TXD and RXD wires.

The CP2102 USB-UART is by Silicon Labs and can be found on
eBay ($2).

an old Cloning or Programming Cable/Plug may not work. The wires
in some are hair thin and many can't be soldered.
PROGRAMMING CABLES
for Baofeng UV-3R
ANTENNA CONNECTION Most
Anytone & Baofeng radios
require an antenna with
an SMA Female fitting.
Most Wouxun KG-UVxx
models require an
SMA Male
fitting. Baofeng UV-3R
requires
SMA-Male,
UV-3R+
requires
SMA-Female
Unlike horseshoes, close doesn't count.
Always confirm the connector type before ordering. example of SMA Female
SMA RP (Reverse Polarity) and
SMA Male
are NOT compatible. Note: SMA-RP connectors are
found on most Wi-Fi Routers.
Examples of Various SMA Formats
Reversed SMA-Female Connectors are
commonly found on Wi-Fi Routers
To use an antenna with a BNC Male
requires the following adapter:
SMA Female (above) to mate with the radio
BNC Female to mate with the BNC Male antenna.
Another option is a jumper (pigtail). This relieves the stress of a
heavier cable when using an external mobile
or fixed antenna.
SMA-F Antenna Extended Threads
Some antennas with SMA-F connectors have an extended thread.
Most radios such as the UV-5R and UV-3R+ require a
standard SMA-F.
The illustration shows two different Nagoya NA-771 antennas.
Some antennas with extended threads ship with a spacer to fill the gap.
Note: If the radio requires extended threads, such as a
BF-888S, an antenna with standard threads
will not make connection unless you trim the outer shell or lip of the antenna
so it is flush with the base.
If the antenna has extended threads and there is a gap or airspace, a #8 O-Ring can be used to fill the gap. Some antennas include this in the package.
If there is no gap or airspace, do Not add the O-Ring. This may actually prevent
your antenna from making a good contact and cause damage your radio.
The wrong threads (if too short) will result in poor reception and over
heating of the transmitter as there is no solid antenna connection.
Erratic Charger Behavior
This includes: Battery not charging, Light staying
Red and Erratic Light behavior.
On many chargers, internal contact to the circuit board is made via
tension clips. If there clips do not have the proper tension or the
copper pad is not clean or is oxidized, a good contact will not be made.
This is normally an easy fix.
