Title: String of strange hex codes
Post by: Roadrunner on March 21, 2012, 05:38:28 PM
Hi there,

I have an SBS3 and this afternoon at approx 14:45/14:46 I received a string of not allocated hex codes with the start and finish times the same. I have had this happen before but this time a large group of the codes all endING in E97 (4DFE97 09FE97 02FE97 017E97 007E97 003E97 001E97 000E97 0DFE97 05FE97) I also had a smaller group 008000 018000 E08000 all at the very same time of 14:45/14:46. In total there were 22 different codes. I have never experienced this many at one time before on any of my SBS1 SBS1e or my new SBS3.

Did anyone else experience this or have any possible explanation for it.

Looking at Reporter I too have these and a number of the "E97" records.

E08000
010000
018000
030000

What Data Settings have you got for Message Filtering?

Hi Anmer,

As far as I am aware have the standard settings as I have not activated any of the "new" ones in the SBS3. I am switched off at the moment but will check them again in the morning. I have been using the SBS3 for just over 2 months and this is the largest group of "not Allocated" hexes I have ever seen at one time  ???

Same here, none of those Message Filtering boxes are checked.

I suspect bad data wrongly decoded.  Be interesting to hear if anyone received these using an SBS-1?

Not on my SBS1 ( I know I am out of (Your) area )
Not even the usual "Russians" which come in pairs often.

Jus these around 12:37
B52520 start/end same sec
one sec later
B5253F start/end same sec
About 10 mins earlier a AWACS popped in NATO13 must have been tactical c/s MAGIC 63
any connection ?

I am in Hampshire and the only "odd" one I picked up was 000002 and that came with the call sign XZ 697

Was that an SBS-1 or SBS-3 Peter?

I am in the East Midlands and picked them up on my SBS-1 at the same time there was a gaggle of F15's about. One of the unexplained codes had a callsign of Hammr, could the spurious codes be from a dodgey pod on an F15 or even an ECM decoy? :-\

Hi There,

I thought I had sent a message at about 6:30 this morning but cant see it so must have drempt it!.

My settings for the SBS3 in Stand Alone Data are all unticked. However in the Non-Volatile Memory settings for the Process Mode S Ait-to-Air replies, Process TIS-B Messages, Process ADS-R Messages and Relay Mode A/C Messages are all ticked. I dont know if that will cause me to get more unaccountable hex codes or not.

Regards

Mike

I dreamt Liverpool were winning 2.0!

I don't have those settings but also got the same codes.

I'm using SBS1e.

Today I picked up 14 "Russian" at various times between 11.42 & 12.02.
120040 (twice), 120034, 1200A3, 12004C, 12AC37, 1233BA, 123487, 1200AA, 121004, 120042, 12AB71, 12D68A, 1200A2.

Thanks Peter.

The SBS-3 is decoding more messages and I was wondering if the vdata alidation wasn't as good.

Looks like it's not SBS-3 related.

As far as RoadRunners encounter is concerned  it looks to me like the box on the a/c failed and in its final millisecond  sent  out a burst of noise which was interpreted by a number of users as code.
There is no trace of  ADFE97 in the days archive after this incident.

Thanks John.  I'm assuming this references those codes ending in "E97" but not these ones?:

E08000
010000
018000
030000

The other posts suggest that the SBS-3 isn't delivering spurious codes which the SBS-1 family doesn't.

E08000 associated with Duke 21
010000 large number of entries came from one sharer only
018000 a handful of sharers , just one burst
030000 again associated with DUKE 21


So just 010000   and 018000 are unaccounted for.

Thanks for all the help with this. I like the idea of a box in itsd death throws!
