Before I buy another KerberosSDR

Post by ve3tkb » Fri Aug 28, 2020 2:05 am


I am considering purchasing another KerberosSDR but Before I do
I have some questions.

The KerberosSDR I bought earlier this year has NEVER worked despite all
the help/suggestions I have sought and been given here. I believe the unit was and is
defective as shipped.

My first question is simply this.

With nothing hooked up to it except a 5 volt 5 amp power source (battery pack) to the Auxilary power port
should I not be seeing the small white light inside glowing? If I hook it up to the main Data port the white light does glow.

My second question is that if I buy another will the Supplier TEST and certify that it is working before shipping it to me?

Thanks for any help you may be able to provide.

You should see lights on when power is connected.

If it seems faulty email [email protected], and cc me at [email protected] for a replacement.

All Kerberos units are of course QC tested for operation at the factory. A very small number will fail after QC though. Hard to know why, but possibly just bad solder joints knocked out during shipping, or silicon chips that have randomly failed.

Does it not mean that Batch testing is a poor way of (1 in 100) say is a poor method of testing for quality !!
