Over the years I have built many station accessories to enhance my operating. Below are some of the notables.

SPC antenna tuner from a design by W1FB from 1986

Link-coupled transmatch from a design by W1SE from 1985

160 meter controller used on my 160 meter inverted-L antenna. Heath-Kit SA-2550 motor-driven 500pf capacitor, Alpha-Delta Arc-Plug arrestor, Balun Designs Maxi-choke balun and Array-Solutions bleeder inductor. Built in 1994

N5BOC Duplex DMR Hotspot using a 3.5" Nextion screen

Heath-Kit SA-2550 controller. This was an e-bay find without the control box. I built one and sold the unit for a nice profit. Built in 2012
