CHIRP

What is the behavior you are seeing?
When setting the Tone frequencies above 156.7 (159.8, 162.2...) an incorrect frequencies is set on radio. Likewise when downloading from radio the frequencies shown in CHIRP does not match the set frequency in the radio.

What is the behavior you were expecting?
Tone Frequencies should match on radio and CHIRP

Can you reproduce the problem all the time?
Problem is reproducable in chirp-0.4.0, chirp-0.4.1 and chirp-daily-20150623. 0.4.0 and 0.4.1 were both tried under Linux and Windows 7 with the same behaviour. Daily was only tried on Linux.

What are the steps required to reproduce the problem?
Choose tone frequency greater than 156.7. Then check radio and the tone on radio will be incorrect. Here is the incorrect mappings I got.
chirp/radio
159.8/162.2
162.2/167.9
165.5/173.8
167.9/179.9
171.3/186.2
173.8/192.8

Is this specific to a certain radio model (driver) or something that you can reproduce with another radio?
Did not have the same issue with Yaesu VX6, VX7 or Beofang UHV5r or Kenwood V71a.
