Do you have the receiver's discriminator brought out of the radio>? Date: Tue, 1 Sep 2009 11:02:32 -0400 From: k1lnx@k1lnx.net To: app_rpt-users@qrvc.com Subject: [App_rpt-users] Using an HTX-202 with a URI I'm putting together a test and development system and my target radio is a Radio Shack HTX-202 that will be coupled to the DMK URI. Has anyone ever done this? Seems like I vaguely remember having to put a resistor in line with the PTT lead, but it really escapes me, would I be ok with just PTT, GND, right or left in/out? This radio also does not have COS so I'll be doing CTCSS on the Asterisk side, if anyone knows of a COS mod let me know.... tnx Stephen -- ********************************** Stephen Brown - ARS K1LNX Johnson City, TN EM86 http://www.k1lnx.net google voice: 423-665-9367 **********************************
