Hi Cecil, thanks for the reply.
I've got a 3A power supply with a short USB power lead originally intended for charging a 16,000mAh battery pack. The charging rate for the battery pack is 2.5A so the cable is rated for probably double that.
I don't have a lead between the SDR and the CHIP specifically because I didn't want to introduce additional variables.
Although it now many years ago, my original vocation was an electronics engineer so I am comfortable with the factors at play. I must say that I am VERY suspicious of the hardware. It runs extremely hot. I placed a heat sink on the wifi module within days of receiving it.
I'd like to hear from the Outernet guys - is there a way using software tools to determine whether this is a hardware issue or a software issue. Again, note the number of people that reported the lack of the LNA LED after the OTA update. @Syed, @Abhishek
UPDATE: and almost as if to emphasise my point the post immediately following Cecils reply also reports the lack of any Tuner activity after the OTA update. If you read through this thread and the oriiginal (before V1.2 got its own feedback topic) you'll note that there are MANY reports of a lack of LNA led or empty Tuner status dialogues.
