The pie diagram seems to be showing that there is data being received. I am not sure how much error checking is performed on that data though.

As far as looking with a scope is concerned. All you can really check for is stuck bits. Just make sure that there is data on all of the pins and none are fixed at 0 or 1. With a dual channel scope you could also check adjacent pins to make sure they are different and not joined together.

Really needs the zip file, only a little bit of it. Not sure what that is you have posted - it should be called something like XXXXXXXXXXXX.TS.

Mike

If you look at it in a hex editor it should look like this with a stream of numbers in hex representing the data nulls etc. If some of the bits are not present....

This is the way to tell if all the bits are working properly. Note you have to use the record switch to record the TS.

Nigel - If the .TS file exists, it will be in the same folder as your MiniTioune software. We only need a 15 second recording of the beacon. You could then .zip it and e-mail it to me.

I suspect a hardware fault with your MiniTiouner as the problem is common to both MiniTioune and Portsdown.

Hi dave,

I have tried version 0.8, 0.9 and 1.01 and the record button does nothing you switch it on and the red light changes but there is never a *.TS file saved anywhere.
Ive been through the ini files to see if there is a setting to say where its saved and its not in there, so no idea how to generate this.

There are three TS files in the directory but there for the test software.

OK Nigel

So a definite hardware fault in your MiniTiouner. The software will not record a TS if it is invalid.

So please check all the data lines between the tuner and the USB module for open and short circuits.

This could also be a faulty 74HC10 - did you use the correct chip? Check it is OK and that there are signals on it. The software will record an invalid TS if there are line errors but not if there are no clock / valid signals which would happen if that chip were faulty.

That file looks OK - but I am not so sure it is a valid TS. All the bits are changing but there isn't enough to see if there is any video in there. VLC thinks there is some audio, which is encouraging.

Did you check the 74CH10 ?
