I was using XM for  weather on the trip March 14 to the Midwest. worked fine. ON the return March  19, the system failed to come up after takeoff from the Midwest. I stopped  in TX to refresh and it worked again. Does anyone else have these problems? Why  does the XM sight provide a self refresh transaction on the net? I am  considering cancelling XM and using the Navworx box on the Chelton to get TIS  and FIS info... I told XM that it is a safety of flight issue, in that expecting  NEXRAD data when encountering adverse weather and being surprised, is not funny.  Anybody else have this problem????

Sometimes our citation WSI fails the same way and  then I notice they did an upgrade or modification.  I have to reboot the  system and then it works fine.  Sometimes it needs 15 minutes of run time  and then reboot.  It doesn't start working until the second  flight.

The problem seems to be with XM where a reboot does not  solve the problem. ONLY A STOP AT AN FBO WITH INTERNET CONNECTION AND AN XM  REFRESH TRANSACTION WHILE KEYING IN THE RADIO ID.. Is the TIS/FIS going to be  any better? Too bad I did not install a STRIKEFINDER..

Had exactly the same problem on exactly the same date. (Afternoon if I recall correctly)



A reboot fixed it for me though.

Is this on the AV-300's, the new receivers that you see these

problems?  My old AV-100 was fairly spotty, but my AV-300 has

been flawless.  Also, with WSI, once you're activated you don't have

to go to any website to refresh.



Some people may remember that last year I flew the NavWorx system

on my Chelton.  It worked for both Wx and TIS-B right out of the box.

The only problem is that FIS-B (ADS-B Weather) doesn't have great

coverage all over the US yet.  Shortly I will be testing the box

again to provide only traffic, so that I can maintain my WSI for

Wx yet get both TIS-A and TIS-B traffic.  If that works, I'll

be all set and will just use it that way until FIS-B coverage is

all over the US.  You can cover so many miles in an RV-10 in a

day that having only scattered regions where Wx is available

wouldn't be any fun.

I think the key in all this is it has nothing to do with the transmission but in how the receiving equipment is acting.  If you are going in and essentially sending a reactivation signal, your equipment is probably the issue and not the XM signal.  This is equivalent to blaming a web site provider for not being accessible if your ISP is down.  I believe that Sirius/XM occasionally reauthorizes receives but the receiver shouldn't time out before receives a new authorization assuming it's used with some regularity.  Either way I would complain to your hardware manufacturer first.

When I was flying for a living, we had numerous instances where WSI  

would not refresh and we had to call WSI and have them do some kind  

of reboot. Then we would have to wait a half hour or so. This is NOT  

the case with the WSI I have in my RV with the AV-350. It has been  

flawless since initializing back in October. Don't know what the  

difference is, but I am pleased with the service. I am following  

Tim's work with the NavWorx system. Sounds pretty cool.

If that is the case then the XM reauthorization should retry as the aircraft

hardware is not ON 90+% of the time. Other XM receivers i.e. car radios have

considerably more ON time than aircraft weather systems even though mine is

ON whenever I am flying.

Not sure what hardware you have, but I use XM on my 496.  It takes awhile to start tracking the weather, but I occasionally get significant delays in updates (45 minutes plus).  After some guidance from the forum I e-mailed Garmin and they indicated the issue was with XM, not the receiver.  Not much we can do about that I suspect.  Rebooting the 496 has a limited effect for me.  Recently the problem has been less prevalent so I hope that’s a good sign.

The problem you describe is an XM chip issue.  If the XM doesn't see a satellite for a while it drops the connection to stop theft.  This was set up long before weather when it was basically a radio only service.  It happens with the cheap XM and the 'certified' XM like I have in my RV.  Real pain in the but ... however the refresh only takes seconds .. especially if you're airborne with you request it.  I've never seen it stop working in flight .. it's always after the aircraft has been hangered for a while.  As I understand it there is really no fix for it, although the weather folks have been talking for some time that there may be a way.

I have implemented XM using the Spruce XM receiver and my own software. Early on I had sporatic problems resetting the box when there was an extensive delay in data reception. It made the box appear dead until next boot.

  

 Another user had problems when stopping and restarting his subscription and getting the timing right for reception of the "refresh". Another significant outage I had was because the whole XM system went down and I needed a "refresh". Once these problems were resolved it has not failed once in the last 12 months and comes up briskly with the first nextrad image within 5 minutes.

  

 We need to focus problems on the exact piece of equipment talking to the XM receiver and the mfg of the XM receiver, and the software version in the XM receiver. The specification for this communication is a guarded secret that nobody will share (with me) so there is much room for errors with reverse engineering.  If you have a copy please contact me.

  

 Also, when the network "refresh" is activated it will not begin for approx 30 minutes and times out after 3 hours - so you need to get the timing and antenna reception right.

  

 None of these comments nor the lack of a clear problem definition surprise me.
