TX lock on VHF
It is a known problem when using high
power on VHF with the supplied earpiece
because of RF getting into the earpiece lead.
Winding the lead through a ferrite core stops
this.

GENERAL
What is the Baofeng UV-3R?
The Baofeng UV-3R is a compact
(*)
transceiver for the VHF and UHF amateur bands, as well
as many of the public service bands. It uses a unique pair of microprocessor - one for the radio
itself, and the other as a control computer: this makes it an SDR (Software Defined Radio).
Further, being a low power unit (2 watts, more or less), it is able to use commonly available
lithium ion batteries, such as are found in digital cameras. As a consequence it is very compact,
easily fitting in a shirt or pants pocket.
The transceiver is fully functional with CTCSS and DCS codes, offset, and shift settings for use
to access repeaters. With the programming cable and software, it is possible to set the “splits”
