Homebrewing a mic boom headset for the Yaesu FT 897 and 857 transceivers

Boom Microphone Headsets for use on amateur transceivers- assembled and kit form.

This online project guide details the construction of a homebrew boom microphone system. It details the assembly of a microphone shell from a 3/4" PVC pipe section and an end cap, requiring a drilled hole for a snug fit of the electret or condenser mic element. The internal wiring schematic specifies a **2.2 K** resistor and a **47 uF** polar capacitor for signal conditioning, with a circuit diagram provided for integration with IC-706 series transceivers. The guide outlines the use of CAT-5 cable for internal connections, incorporating strain relief at the rear of the mic shell, and an inline 3.5 mm jack to facilitate an external _PTT_ line, designed for a foot-mounted switch. Further construction involves fabricating a microphone shock mount from a 2-inch PVC connector, detailing the creation of four "fingers" and the insertion of screw-eyes for attaching elastic bands, which are twisted 180 degrees for tensioning and vibration isolation. A foam wind screen is also incorporated into the microphone assembly, secured with adhesive. The boom arm itself is repurposed from an articulated architect lamp, with the original lamp assembly converted into a **60 watt** resistive load for testing power sources. Microphone cabling is secured to the boom arm using wire ties, ensuring sufficient slack at hinge points to maintain articulation. The boom base is mounted to a bookshelf, requiring specific positioning to achieve proper microphone placement in front of the operator. Performance evaluation of the microphone system is conducted through on-air audio signal reports from other amateur radio operators.

Radiosport headsets & boom-mic headsets for amateur radio

On this page, you will find one of my designs; An Audio Selection Panel (ASP). The Audio Selection Panel allows you to control 4 Transceivers and hear the audio through the built-in loudspeaker and on an external boomset (combination Microphone/ headset). On or more transceivers can be selected at a time to transmit and/ or receiv

The ham radio population is aging, primarily consisting of Baby Boomers and older generations. The author, a spatial demographer, has studied the population dynamics of ham radio enthusiasts, particularly those involved in amateur radio contests. They have published several works on this topic and have written about it in their Social Circuits column, with more writings expected in the future. This document presents a modest analysis of aging and radiosport participation among amateur radio operators, using survey data from the National Contest Journal (NCJ) and two regional ARRL surveys. The results suggest that age is related to contest participation, with older hams tending to engage in more contests per year. However, the author notes the limitations of the data, which are based on voluntary response samples rather than random samples. The paper also examines the sources of contest information used by hams, finding that older contesters favor traditional sources like the NCJ, while younger hams prefer online sources
