Thanks for the info Kyle, I'm really looking to mute the MDC1200. I like the MDC control especially since I can program contacts per command into my radio but I have several users that don't like the mdc noise which is understandable. On an unrelated topic; I see that if I place 100 and 123 in the rx section the node will decode either but transmits on the default which makes sense. What's the txctcssfreqs line for? txctcssdefault=100.0 rxctcssfreqs=100.0,123.0 txctcssfreqs=100.0,123.0 thanks for humoring my stupid questions 73 de K0JSC ________________________________ From: K&R Yoksh [mailto:yokshs@gmail.com] Sent: Wednesday, September 19, 2012 10:29 AM To: Jeffrey S. Carrier; app_rpt-users@ohnosec.org Subject: App_rpt Hi Jeff. I'm doing this same thing on my nodes. Check out the DTMF script on my web page: http://www.qsl.net/k0kn/scripts.html This will allow you to send commands to any node within the same server. 73, Kyle K0KN
