All, Thanks very much for all of you that have been very helpful in helping me get my first node going.. I have learned a lot from you guys and I look forward in returning the favor! I am thinking even about doing a youtube video to help promote the project, if anyone would like to help in this effort, let me know. Now, to my next question. I Just need clarification on the purpose of the following two inputs used on the URI CTCSS_DET COR_DET If I use CTCSS decoding within the receiver, would I set the repeater configuration to use appropriate signal on CTCSS_DET and just set the COR to none? I never use CSQ, so I assume I would never use the COR_DET line, correct? And let's say I used RX Discriminator processing on another node and not rely on the receiver CTCSS decoder, do I just not tie the CTCSS and COR to anything and set them to none? And I assume I set CTCSS From:: to "decoding using RX audio in DSP" Correct? Thanks 73 Lu KA4EPS Node 27869 Next deployment batch of nodes this week, 27875, 27870
