@leviaton I hear ya. What I can tell you is that received my replacement MGW310 a week or two ago. My initial point about GPS signal remains true, meaning 360 line of sight is critical for any GEODNET at least in my location. I can’t prove the GEODNET side performance just based on my unit being mounted higher on a 14th floor balcony of a 15 story building, I still average without looking at it all the time throughout the day is that you need at least 28 satellites on average or more to earn GEODNET. I’ve read some things on areas in the U.S. regardless of location, satellites are sometimes shutdown for several reasons.

But regardless, the replacement MGW310 has been working well back to my my original optimal standards on Wingbits, if not better. On that note, I know Hyfix has been producing/shipping to distributers like Helium as soon as they have a new batch to send. I may have gotten fortunate or just one of the earlier ones to submit a failure request alonf with my Wingbits ticket provinng the troubleshooting along with the Wingbits team. That may help too if you have a ticket just by chatting with Wingbits, even though it’s a bot to start, it’s an impressive bot. But eventually working through it with the bot help, the chat went to a direct representative (it is a little time consuming, and take screenshots of the graph1090 and tar1090 graphs before and after).

Important for others maybe not you since it seems you are just waiting at this point for a replacement. Because part of the troubleshooting is a factory reset, and all previous graphs are not stored unless you had a previous way of storing the information or just hanging on to old screenshots of the graphs, showing/proving when the unit failed. The built in LNA was my cause on Wingbits.

Whenever you do get your replacement, all I did was make sure the antenna base was hand tight along with the connector, and also take pictures of the internal connection pin of the antenna so you have a point of reference…because during troubleshooting on of my other issues is that the pin on the antenna was pushed in to far to make solid contact.

You can take the antenna apart although I don't recommend it. One, because it can make it worse and maybe void warranty unless instructed too by Wingbits/Hyfix. Second, it is very delicate and the only reason I did it and verified all the above was because I’m an aircraft mechanic and know how to be very careful with it and over-torquing issues.

That said, that is how I verified a pushes back pin and was able to correct that problem. I then still had the issue. Which essentially verified it was the known issue with the LNA’s. I’m almost to the one month point with the new unit and no issue yet, but as you mentioned, mine initial unit also failed at almost exactly one month. So will continue to monitor but good so far with the replacement.
