[App_rpt-users] Re : RTCM PTT circuit

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 .

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?
