Eric,
I have answered you questions inline:
>>Are you seeing any over or underruns ("uOuO" or "uUuU") on the console?
Occasionally, I see "u0" on the rx. But, even if i post process data
offline, i still get the "flip"
>> How wide is the signal you're trying to send?
The rx interp is 256 and the tx interp is 512 giving a BW=250Khz. Since I
am just sending random samples, I am using the whole band.
>> What interpolation and decimation values are you using?
See above.
>> Try sending it at 10MHz.
I did. The Rx cannot see my signal anymore; a PSD confirms this. Not
sure why.. maybe an antenna issue.
>> What version of GNU Radio are you using?
I do not know what version the radios are. How do i find this out? The
serial numbers are 1460 and 1461 and there is a date on the sticker that
says 4/16/07.
>> Have you isolated the problem to the Tx or Rx path?
I believe it is in the Rx path. The TX path simply reads up a data file
of samples and sends them to the USRP... very simple. The RX path receives
the data and attempts to correlate on the samples I sent. However, I am
noticing that the correlation is postive, then negative, and continues this
way alternating about every 1000 samples or so.
