Anyone interested in a new computer? I feel like building a new system
around the core 2 duo processor but need to sell my present system.

I wrote a BandText table that contains all Region 2* frequency assignments
from 10 KHz to 53.999 MHz. It contains the new amateur assignments that
were included in the Flex radio 1.8.0 release.

region, I picked the one tha
Yes, I just went back a few revs and see the same thing. I'm wondering
if the difference may be using a wide-band noise source vs. a CW tone
(as in the case of a signal gen.)?

Kirb,
I've seen the same thing for the last few releases but only when the DSP
buffers are set to 4096, at lower settings the calibration is correct. I
have discussed this with Eric but he cannot duplicate it with his equipment.
I calibrate using -73 dBm and consistently get -70 dBm on the meter

Bob,
Thank you. I have the same opinion, but wanted to be sure. I will
change back to Blackman-Harris.

Is it me or is the input level calibration out by 3 dB in v1.9.0 (795)?
Dumping a -70 dBm into the front end of the SDR (HP 8648C derived)
equates to -67.0 dBm repeatedly for Pre-amp Gain settings of "low/Med/High".
Using a new .mdb for this load and have run the Cal routine after

The number of taps and the lag are fixed by the block size chosen for
this. It is much larger than the non block lms filters, runs faster,
and converges quite a bit more quickly (thus the need for lower gain)
because it adapts the taps in blocks. This must be balanced against
the ability to

Just to be absolutely clear, are you saying that with Block LMS checked it

matter what figures are set for taps/delay (they could be set to zero for
instance)
because they play no part in the NR and ANF process.

Ahti:
I do not know how this changed happened or when. Blackman Harris is
now the default (svn 795).
Blackman Harris window when used in the FIR design does indeed give the
best out of band rejection BUT AT A COST. The Q goes down slightly
(shape factor slightly worsens). There is no such

Try moving the audio card into a different slot if it is PCI. It sounds

Block LMS is now the default for both. NR gain 10, ANF gain 25 are
the new defaults. The NR default gain of 50 renders the Block LMS NR
useless and even the notch filter gain is too high. In Block LMS mode,
ONLY the gain has an impact.

One suggestion, before changing from one revision to another, ALWAYS
BACKUP your current sub-directory or install the new version in a fresh
new sub-directory. ZIP is now build into XP so you can zip up your
current setup and save it for reference or restoration.
