[hpsdr] Mercury Problem

[Dave Wilson]

Hello All,

 

Finally got my system up. Mercury, PennyLane, Alex, Metis & Atlas. Sadly
after a couple of days the Mercury receiver lost audio both line out and
H/phones. All one can hear is a very high pitched tone plus the DC RX supply
current has increased to about 2.5A (was 1.5). The board is also getting
quite warm in the region of LTC220B (U5) which I think may be the A to D
device.

 

Is there someone around who can repair and test the card? It is well beyond
my eyesight capabilities.

 

73's
