[hpsdr] Exceeded power of Penelope: 630mw

[Tokio Endo]

Hi All,

As per the problem of Penelop exceeded power, I replaced OPA2614, analog amplifier on the board. Compared with a normal spare Peneloe, I found that exceeded power aound 630mW is <<not actual forward power displayed on PowerSDR meter>>.  It is almost the same forward power as that of the spare Penelope, it is around 250mW, since the two boards drive my 100W amp at the almost same output. However the defective Penelope put powers slightly smaller than the normal one.

Can anyone explaine this observation ? I doubt LMC6482AM is faulty.

Regards,

I replaced this problematic Penelope card by TAPR Penelope without any change of PowerSDR, then the output power becomes quite satisfied. Therefore any setting of PowerSDR would not be a cause and the problem would reside on the Penelope card as well. My question may be which parts of the Penelope board I have to change.

You can test whether this is so by deleting the database.xml file and letting the HPSDR PowerSDR program build a fresh one for you.  If there is no change in your symptoms the original database.xml file was likely fine.
