Rog,
The SDR dongles tend to run very warm as they need to dissipate quite a bit of power when working hard. Under normal circumstances, this is not an issue, but in a confined space, or where there is anything which could interfere with effective heat dissipation (such as Rob’s padded case for example) the excess heat tends to be absorbed by the USB hub metalwork and can be transferred to the other dongles, very occasionally causing one or more of them to fail, which is what happened in Rob’s case.
PilotAware Hardware will of course replace ‘faulty’ components under warranty, but users should try to minimise anything which will/might reduce the unit’s ability to dissipate any excess heat.
In this case it was decided to replace the ‘defective’ parts free of charge, so Rob is now happily back in action.
Regards all and Merry Christmas
Peter
