Take a look at the Modem Tab in the client, there you can monitor
the quality of the link. You can watch:
* Signal/noise in dB (may be different scale for different modes,
typical value for PSK500R on a reasonable link is > 20 dB)
* Link quality, 0-100%
* Blocks undamaged
* Block size
One possibility that comes to mind is that in fldigi:
Config->Misc->Pskmail 'Reset to Carrier' and 'Report ARQ frames average S/N'
are unchecked in the client, resulting in 0 values....
