Inexpensive Chinese radios, such as those produced by Baofeng Technologies are popular as starter radios due to their low cost. They are also used as disposable or spare/back-up radios.

Learn about the internal architecture of the Baofeng UV-5RB in the Teardown Tuesday: Baofeng Amateur Radio Transceiver article on the All About Circuits website.

This article describes the disassembly process and includes a video of the tear down. It also includes circuit board photographs, a schematic diagram, block diagrams of the major components used in the radio, and links to data sheets for those major components.

This antenna is based on the WB0CMT (SK) “7 dB for 7 bucks“ antenna design (published in the April 1993 edition of QST Magazine).

The Forx Amateur Radio Club 146.940 repeater has been replaced with a newer model GE Mastr III. It now has a CTCSS tone of 123.0 hz, and is operating at an output power of about 55 Watts. A preamp has been installed to improve the repeater’s receive sensitivity.

“As of 1400 UTC on January 16, ARRL Logbook of The World (LoTW) no longer will accept contacts that have been digitally signed by versions of TQSL earlier than version 2.0. Users of earlier versions are encouraged to upgrade as soon as possible, as older TQSL versions contain uncorrected defects and display inaccurate error messages.”[ 1 ]
