Title:
  Yaesu FT-897 frequency drifts in rigctld

Status in hamlib package in Ubuntu:
  New

Bug description:
  When doppler shifting in Gpredict, the static frequency changes. By
  inserting test points into the source code, we traced this back to
  hamlib getting feedback from the FT-897 that it interprets to be dial
  tuning, so it adjusts the static frequency and therefore 'drifts' off
  frequency. We tried in an older version of hamlib (1.2.10-3) and found
  this still present as an issue.

  The problem was initially thought to lie with Gpredict, but on further
  troubleshooting is more likely with hamlib
  (http://ehc.ac/p/gpredict/mailman/message/31445857/).

  The problem is more obvious at higher frequencies (tested at UHF and
  VHF, it was more present at UHF).

  Setup has included all the following combinations:
  Ubuntu 12.04.1, 14.04, 14.04.1
  Gpredict 1.2,1.3,1.4
  Hamlib 1.2.15.1-1, 1.2.15.3-2, 1.2.10-3
  Yaesu FT-897

  Hamlib was activated with
  rigctld -m 123 -r /dev/ttyUSB0 -s 38400
