CHIRP

Installed chirp-daily from ppa (20140724~trusty~1, Ubuntu 14.04.1 LTS amd64)

The 6m FM calling frequency in the US Calling Frequencies.csv file has a negative duplex value set.

To recreate the issue: Select the "open stock config" from the file menu and load the "US calling frequencies" csv file. Look at the duplex column on the row with the 52.525000 entry (channel 1).

Problem summary: Duplex value set here should be "(None)" with offset 0.000000 just like the other 2m, 1.25m and 70cm FM calling frequencies.

(NOTE: These FM calling frequencies are used in Canada as well as the US. There are also typically other standard calling frequencies used for other modes such as SSB, CW, AM, etc.)
