Hello to the list. I hope someone can shed some light on a problem
that I am experiencing. The setup here is a Pentium 4 3GHz - 512 BM -
Delta 44 , VAC and VCOM. I am using MixW for my digital modes.
I am finding that while I am able to control the MixW software and
decode digital transmissions, I seem to experience a pulsing action
(approx 1 sec intervals) on the transmitted signal. On PSK or RTTY you
can also clearly notice the pulsing action on the panadapter display
of the PowerSDR console.
I thought that this problem could be related to the VAC settings. I
adjusted the buffer size in the SDR VAC setup from 512 - 2048. With
the lower setting the pulsing (still occurs but not as frequent)
however it is much more pronounced (almost seems stronger as well)
when I have the buffer set to the 2048 setting.
I thought that perhaps I had a SWR problem with the antenna so I
tested the SDR with a dummy load and experienced the same problem. I
have monitored my signals on another receiver and am able to hear the
pulsing action.
Any help/guidance would be greatly appreciated. Thank you all in advance.
Regards,
Serge
