Impressive!

Wonder what this is at 5300Khz? - its always there.
A quick update.
I received the DC power supply, gave it some tests and it seems like a nice stable 5.18V on the output.
I replaced the two Apple bricks, one for the KSDR and one for the Bias Tee, and connected them to the new linear DC supply, and from what I can tell, the "noise" is all but gone on that frequency.
Will monitor and report any additional findings.
Parts used:
- 13.8V 5A Transformer (From an old Dick Smith unregulated power supply.
- This DC power supply with a 5V fixed regulator.
- A dual USB assembly from an old PC
Left to do:
- mount it all nicely in an enclosure ;-)
