Just when we thought maybe table #31/1F might get us all the way through the winter, ARINC has updated its ground stations to frequency table number 32, or 20 in the hexadecimal notation the HFDL system uses.
According to several posts to the HFDL group on Yahoo, the only change is to fix a frequency error in version 31/1F that had aircraft looking for Shannon on 2988 kHz, while the ground station squittered away all alone on 2998. It seems awfully coincidental that the mistake was corrected right after the frequency anomaly was discovered and discussed on this same group. It would be very cool if this hobby, and not just a coincidence, was indeed the reason ARINC fixed it. Always glad to be of service.
Let's hope that Shannon now gets more activity on those long winter nights.
The new pchfdl.dat file has been posted to this column's web site. It should be the same one as posted to the Yahoo group, and successfully installed here. Rename your old pchfdl.dat and copy this one in its place, then start PC-HFDL and it should show the frequencies instead of just numbers.
We thank the Yahoo group people for being so on top of things.
