Hi Bob,
Just tried the latest test code. A HUGE improvement in the AGC performance -
sounds just great - many thanks.
Now, about the speech compressor.. :)

It would be interesting to see the same analysis done with the Compander in
various configuration setting (using the higher compander radios of the DX
mode)

Yesterday I set the Sample Rate back to 4800 khz, just to see how great the
RX filtering can be. It has been a long time since I used the 4800. Wow,
there really is a big difference in the RX filter curve. I can even hear a
difference between 100hz and 50hz. About a month ago there was a
I just wanted to take a minute and mention how much I appreciate the
support I have received from the Flex group; especially Eric. I have
started working a bit with Visual Studio.net and had questions; Eric
answered all of these extremely quick and right on target. The main thing
here is that he

Sure would be fantastic to have the great filtering but with the nice wide
spectrum and very low latency of the 192 or 96 sample rates.
Your wish may be closer than you think.
There is some work being done on multi-rate DSP (down sampling) and that should
give you what you wish for. There
Hi guys
I have a beta release of FlexLoader that fixes the current terminal
bug but one tester reported some anomalies when running the new beta
release at 1920 x 1200 (you probably need a 24 monitor to get this
large a window). If you have a computer that can run this resolution
in a stable

I think you'll see that a number of these issues either hadn't crept into
the Linux version, or else had been addressed previously. Bob has been very
good about maintaining the canonical version on CGRAN; I've tried to do the
same.
A lot of what needs to be done is simply reconciling the
If yoiu want to look at what the Flex looks like when ypu turn on the compander
just turn on one of the scope modes and talk in the mic

Ahti OH2RZ recently sent a link to an article that looked at the K3 speech
processor.

I found it interesting you need a room full of test equipment to analyze the
K-3's performance. With the Flex radios you need to turn on
I recently noted that FlexRadio is now offering a 6-pin to 4-pin Firewire cable
for laptops. I was under the impression that a 6 pin cable was required with
the Flex 5000.I have a Dell XPS 1530 laptop with a 4 pin Firewire input. A 6 to
4 pin adaptor happened to come with a Firewire card I got

Thanks for the new code. My HF noise aboard a boat is atrocious on
some bands. The sonars harmonic pulses are gross on 75M and the NB will
take it out but high level SSB nearby distorted the audio I would be
listening to greatly before. Tried your new test code last night and the
I want to prepare this group for some testing that needs to be done.
I have an approach in mind that will let us roll out RX adaptive IQ
immediately. It works as follows and the work is done in the TX IQ
cal to make it happen.
1) TX IQ calibration session is initiated.
2) DDS Generator is

Thanks. This is the kind of report I am looking for. Where you state
your results, the impacts, the equipment used and it has a story so I
can get the context because I am so thickheaded.
Thanks!

Thanks
Duffy,
The performance issues you described are, I believe related to the ATOM. I
have the same issues on the ATOM I use. I believe that once the modifications
Bob is planning for the DSP are realized, the computational overhead will
decrease enough to make the ATOM viable at the higher
Thank you Lee for bringing up this valuable feature of the Flex and
other SDR equipment. Proper use of compression (or clipping) together
with equalizers and filters makes high power amplifiers unnecessary in
many cases. Try this concept and you'll find that you can manage in DX

Before now, flexradio and flexradio developers (just like that) were
side by side in my Address Book.
Now they read FLEX USERS and Flexradio DEVELOPERS and I hope not even I
can make this mistake again.
My last email note was NOT intended for the former, it was intended for
what we

The new driver has some performance and stability fixes in it. Thanks for
validating it since it is a beta and all feedback is very useful.
