What's wrong with using an MOV across the coil, with a .1 uf capacitor in parallel with it? That's what I do. The relay opens almost instantly when the coil is de-energized.
The value of the MOV should be a few volts above the coil voltage. For example, an 18 volt MOV for a 12 volt coil. 73, Mike www.w0btu.com _________________ Topband Reflector Archives - http://www.contesting.com/_topband
