Dan,
I'm testing Chirp with UV-3R files.
1. Why did you delete the Name field? I would find this very helpful for organizing and editing the data in my .CVS file. From our previous email conversation, I understood you were going to retain it in the CSV file and only drop it when writing data to the dual_band.dat file for uploading into the radio?
2. Vero/Baofeng uses one "menu" for manually setting the Tx-Code (transmitted CTSS or DTCCS code) and a second "menu" for manually setting the Rx-Code (received or SQL tone code, either CTSS or DTCCS).
Chirp has separate fields for the CTSS (Tone) and the DTCCS (DTCS Code) (defaulting to the lowest code value for whichever code type is not used). In addition, Chirp has a field Tone Mode with values of None, Tone (CTSS Tx only), ToneSql (CTSS Ts & Rx?), and DTCS.
The "inputs" suggest that a repeater using CTSS will always have to hear a user's Tx-Code and it may or may not send back using a CTSS code. On the other hand, if the repeater is using DTCCS, then, it will require that code (my Tx-code) and it will always broadcast using that same DTCCS code (my Rx-code).
Some questions to help increase my knowledge of current practices:
1. Is the above analysis correct? 2. Is this juxtaposition of data and information types done as a convenience in light of the requirements of earlier radios that Chirp was programmed for? Or, it it something that can be altered? 2. Is a repeater operator precluded from selecting different CTSS or DTCCS codes for Rx and Tx?** 3. Is a repeater operator precluded from selecting CTSS for the user's Tx Code and DTCCS for the user's Rx Code (or vice versa)?** 3. Can an operator set a repeater up to use DTCCS on what it receives (the user's Tx Code) and transmit without a code?** ** (Assuming the operator's choices do not conflict with any other repeaters sharing the frequency pair within a reasonable distance of the subject repeater.)
I don't see where the UV-3R uses the DTCS Polarity information at all; it does not appear to be an option as I read my .dat file.
