King Air NAV 1 Offset and Intermittent DME
-
Regarding the King Air.
Last night I installed two new addons, the TBM850 and an unrelated addon from the Inibuilds site. Since then, my Nav 1 radio on the Analog King Air has an offset that's variable around 10 degrees. the offset gets larger the closer I get to a VOR. This offset shows up on the HSI and the RMI. Also, the DME for NAV 1 is extremely intermittent. I just tested with a default aircraft and there is no such offset.
I am also using the TDS GNX, but the last two flights where I noticed the issue, I had the cockpit configured for no GPS Units.
Any advice? I would do anything to not have to reinstall MSFS.

I'll start by saying that, despite others frequently touting this as a solution, I have been using MSFS heavily for four years now, and have not once reinstalled it. I have never seen a reinstallation be required to fix something that could not be sorted out another way.
Regarding your issue, what exactly do you mean by "offset"? Do you mean that the needle begins to swing as you approach the VOR, then signal is lost before being reacquired on the other side, and finally the needle comes to center again as you get further away from the station? If so, this is one of my features that I am most proud of, as distant signal attenuation and loss of accuracy over the stations "cone of uncertainty" is not simulated in the base simulator. As for the DME, what do you mean by "intermittent"? Does the DME signal actually drop out, or is the update time just slow? I have seen DME information from the simulator become extremely confused when reloading flights before. That code has been unchanged in the simulator since about 1995 to the best I can tell. Let me know if this answers any of your questions, or what else I can do for you. Thank you!

Hi...
No, it's not what you expect from overflying a ground based Navaid.. It's literally an angle offset error. First time I noticed it I was tracking a VOR radial outbound and I realized I needed a very large track correction to keep the HSI needle centered. It was acting as if I had a 100 knot crosswind. Then I did a few tests flying direct to a VOR inbound with the RMI 1&2 VOR needle, the HSI and the #2 OBS all set to the VOR. I noticed that any needles on the #2 nav would track the VOR correctly, but the needles on the #1 Nav were pointing roughly 10 degrees to the left and the closer I got to the VOR the bigger the error. It's almost like if the #1Nav radio was tuned to a phantom VOR that was always left of the one that it was tuned to. I was backing this test up by using the default MSFS VFR map.
Also, the NAV 1 DME was intermittent past 11 miles.. I could listen to the DME on the audio panel as a strong morse signal, but the DME indicator was blank. This was while tracking a back course localizer where the fixes had DME references out to 30ish miles from the localizer.But the good news is, I just reinstalled everything associated with the King Air, including FSUIPC, TDS GTN, The Caravan and the 850 which I just bought last night, making sure to install the King Air and the TDS last and it appears whatever it was is now squashed. I kinda wish I had reinstalled things one at a time so I could at least find the culprit, but this beats any longer process off troubleshooting.
