Note that the receive range for all versions of this radio is 65-108 MHz, 136-174 MHz, and 400-480 MHz. This build seems to only accommodate receive (and transmit) frequencies in the U.S. transmit range (144-148 MHz, 430-450 MHz).

Also, this radio has three versions: Asian, European, and USA. MARS members (like myself) use the Asian version, which transmits 136-174 MHz and 400-480 MHz. It would be nice if transmit frequencies for any of the three versions could be accommodated in CHIRP.

The following Yaesu link (numbered page 30, PDF page 32) shows the frequency ranges of the various versions of this radio: http://www.yaesu.com/downloadFile.cfm?FileID=14688&FileCatID=151&FileName=FT%2D4XR%5FXE%5FOM%5FENG%5FEH069M201%5F1805M%2DBC.pdf&FileContentType=application%2Fpdf

[ft4] driver restructure (#7615)

While implementing two more radios of the Yaesu FT-4 family (the FT-25, see #7543, and the FT-4V, see #7387), I found that with some moderate reorganization, implementation of new radios will become easier. The proposed reorganization implements one more interstitial layer of inheritance to support the sub families of FT-4 (containing the FT-4X and FT-4V) and FT-65 (containing FT-65 and FT-25). Also, some variable assignments have been moved from the individual radio classes to the SCU-35 base class and to the interstitial classes named above.

This change also adds the infrastructure for adding European or Asian models, and as such prepare for addressing a number of currently open issues (6.25kHz tune step issues on EU models, frequency limitations; see #6619, #6651, #6677, #6761, #6869). It will also make it easier for a few additional fixes for issues which were found during my work on this driver (#7601, #7603, #7605). I will submit these fixes in additional patches.

Fixes: #7615

I had marked this issue as a "Feature", but I suppose it could also be considered a bug. In the olden days, we used to always say "it's not a bug, it's a feature!"

Separately, as a temporary work-around I find that I can prepare a CSV file with the desired frequencies (outside the U.S. amateur allocations), and then import the CSV file.

  • Status changed from New to Closed
  • Target version set to chirp-daily
  • Model affected changed from (All models) to Yaesu FT-4XR

This should work now.
