Thanks very much for your response. Here are the available columns: Frequency, Tone Mode, Tone, Tone Squelch, DTCS, RX DTCS, DTCS Polarity, Cross Mode, Duplex, Offset, Mode and Skip. Most of the columns have dropdowns with limited values (Tone Mode has only three options TSQL, DTCS and Cross), and the DTCS Polarity column (for example) is forcing me to enter a value of NN, NR, RN or RR. What do I do with that? In any case, it's a bit confusing trying to shoehorn some of these values into columns that don't seem to correspond well. Can you help me identify which values go in which column?
