1. [Amps] keying issue resolved (score: 1): Author: <ka9egw@ka9egw.com>; Date: Wed, 28 Dec 2016 08:17:31 -0600; My sincere thanks to all who responded. After serious consideration I got inspired to keep it simple-a 240VAC 30A solid state relay with the low side of the 3-32VDC input pulled to ground by any of s; /archives//html/Amps/2016-12/msg00463.html (7,231 bytes)

Most AC solid state relays use thyristors for switching and depend on the zero crossing of the AC load to switch off. In other words, if you try to use one of those relays t; /archives//html/Amps/2016-12/msg00464.html (8,430 bytes)

Re: [Amps] keying issue resolved (score: 1): Author: Jim Garland <4cx250b@miamioh.edu>; Date: Wed, 28 Dec 2016 08:14:10 -0700; Yes, an optically coupled MOSFET relay will work fine, and is what I use in my StationPro keying circuit. Two other considerations are the on-state resistance and the switching time. The PLA140 relay; /archives//html/Amps/2016-12/msg00471.html (9,960 bytes)
