Hi All

Jen, G4HIZ reports that the Portsdown, with a LimeSDR Mini and a PE43703 attenuator, has a much lower output on the first transmission after boot than subsequent transmissions. However, I have been unable to reproduce the problem.

Has anyone else seen this behaviour - if so, any clues to help solve it?

Hi all,

for the benefit of anyone else who may experience the same issue, this was traced to the Data and Clock lines being transposed going to the PE43703 programmable attenuator. Once corrected all worked fine. It was surprising that it 'worked' to any degree at all given the initial connections !
