Using a transistor would be wise even if the rtcm can do it. Its simpler to replace a 22222 then to fix a rtcm if something goes wrong . --- Message initial --- De : "Bryan Fields" <Bryan@bryanfields.net> Envoyé : 7 mars 2014 17:52 A : app_rpt-users@ohnosec.org Objet : [App_rpt-users] RTCM PTT circuit I'm interfacing the RTCM with a hamtronics exciter and will be using a small relay to key it. Can it sink 100 ma to ground for the relay or do I need a driver transistor? -- Bryan Fields 727-409-1194 - Voice 727-214-2508 - Fax http://bryanfields.net _______________________________________________ App_rpt-users mailing list App_rpt-users@ohnosec.org http://ohnosec.org/cgi-bin/mailman/listinfo/app_rpt-users To unsubscribe from this list please visit http://ohnosec.org/cgi-bin/mailman/listinfo/app_rpt-users and scroll down to the bottom of the page.
