Re: [Flexradio] RFI on 10 meter

[Chris Maukonen]

Ulf,

I am not currently a Flex user. Was in the past but this is kind of a 
general - non-flex issue.


I am assuming from what you said that your shack is in the barn.

If this is the case remember that the counterpoise - the metal roof on 
the barn - is the other half of a 1/2 wave dipole.
Being such it will be hot with RF while transmitting. So you are 
essentially sitting right underneath an RF source.


Not good.

All I can suggest is better shielded mike cable and ferrite chokes on 
the mike cable and probably all other cables as well.

I have a ground strap from my FLEX to the PSU on my computer and also ground to

bad.

You will need to describe more of your setup.  Antennas, grounds, type of mics, 
etc.

If you have a ground on the radio, try removing it and see if it clears up.

RFI issues require a lot of trial and error testing.  It is not a fault of the 
radio unfortunately.

I prefer manuals written by the people who have actually used the
product to manuals written by tech writers who have never used
the product and/or engineers who do not know how to write.

After over 25 years in computers and electronics I can assure you
that the former rather than the later are much more useful and
intelligible.

Case in point. IBM manuals.

Ed,

My experience is this. I set up the exact situation a while back. The 
thing you need to watch out for is that XP wants to "own" all the
drives on your system. So you need to do one of two things. Either
load XP first and note which drive you want as you XP system drive,
then load linux.

Or disconnect the linux drive when you install XP. I am not sure
about Ubuntu, but I believe the install will as which drive you want
to use and format that one for you. (I used Fedora..Now I have an
Apple and run OS X and use remote desktop to the XP box for SDR.)

As far as dual boot goes, someone else will have to help you on that
as I did not use that feature in either system. I simple set my bios
to prompt for which drive I wanted to boot.

I've had a similar thing happen to me. It turned out I was getting some
RF into my audio/computer interface. Took a while for me to trace it down,
but better grounding and ferrite on the audio cables and now all works OK.

Just my experience.

A couple from Radio Shack and a few from a local surplus store.
Skycraft Parts in Winter Park, Fl. The ones from Skycraft would fit snug
around the cables I was using so I pulled the connectors off, slipped
the ferrites on and put the connectors back on.  Worked like a champ.
Connected to an antenna or a dummy load, there is no appreciable "grass"
or humps. Disconnected, there is.

Well I currently have a Rhode NT1 mic into a Yamaha mixer
with an Alesis NanoCompressor set to limiting only. Seems
to work just fine.The mixer is side chained through the
insert. I also have the C-R output of the mixer
going to another mixer to monitor myself since I
use headphones exclusively as my hearing is quite poor.

Interesting thread. I currently use a small mixer for my mic preamp with

set to be a brick-wall limiting only. Works very well. By the way that 
is what they used to
do on am broadcast stations. No compression, just limiting.

I am using Delta 44 car also. You need to go into the Delta 44 control 
panel under Hardware
and set the inputs and out signal levels to consumer, I believe. That is 
what I have done and
I have no problem. The Edirol is a better inter face, though and if you 
have one it might be worth
a try. You'll have to reconfigure and recalibrate if you do this.

I'm using a D44 and have the hardware settings on the MAudio control panel
set to 96k/512 and DSP settings set to 4096. I have no problems with this.
No clicks, pops, crackles or (glug glugs :-) ).

Computer is a Dell Optiplex 745 with an Intel Core 2/Duo and 2gig ram.

AGC set to MED and RF set to 77. Preamp set to High (Mediocre antenna).

Re: [Flexradio] OT Messages (was ARRL)

[Chris Maukonen]

In keeping with the discussion: :-)

Q: How many internet mail list subscribers does it take to change a 
light bulb?

A: 1,331:

1 to change the light bulb and to post to the mail list that the light 
bulb has
been changed

14 to share similar experiences of changing light bulbs and how the 
light bulb
could have been changed differently.

7 to caution about the dangers of changing light bulbs.

27 to point out spelling/grammar errors in posts about changing light bulbs.

53 to flame the spell checkers

156 to write to the list administrator complaining about the light bulb 
discussion
and its inappropriateness to this mail list.

41 to correct spelling in the spelling/grammar flames.

109 to post that this list is not about light bulbs and to please take 
this email
exchange to alt.lite.bulb

203 to demand that cross posting to alt.grammar, alt.spelling and 
alt.punctuation
about changing light bulbs be stopped.

111 to defend the posting to this list saying that we are all use light 
bulbs and
therefore the posts **are** relevant to this mail list.

306 to debate which method of changing light bulbs is superior, where to 
buy the
best light bulbs, what brand of light bulbs work best for this 
technique, and
what brands are faulty.

27 to post URLs where one can see examples of different light bulbs

14 to post that the URLs were posted incorrectly, and to post corrected 
URLs.

3 to post about links they found from the URLs that are relevant to this 
list
which makes light bulbs relevant to this list.

33 to concatenate all posts to date, then quote them including all 
headers and
footers, and then add "Me Too."

12 to post to the list that they are unsubscribing because they cannot 
handle the
light bulb controversy.

19 to quote the "Me Too's" to say, "Me Three."

4 to suggest that posters request the light bulb FAQ.

1 to propose new alt.change.lite.bulb newsgroup.

47 to say this is just what alt.physic.cold_fusion was meant for, leave 
it here.

143 votes for alt.lite.bulb.

I have one. It's what I use with my SDR1000 and love it. About the same

I don't have any specifically. However I believe the newest ones that

supposed to be a lot quieter EMI wise than those that use SCR's.

Get a copy of Windows XP and reinstall over Vista. Maybe if enough

Re: [Flexradio] integrated Mini-ITX - Linux

[Chris Maukonen]

y is no ALSA support
for Firewire attached audio cards. You have to use a raw Firewire I/O 
library and do low level I/O
programming.  I would also totally divorce the GUI from the DSP code so 
I could run the DSP code
at the highest priority and use any one of a number of inter process 
communications APIs such as
sockets or semaphores or shared memory. Oh and interrupt driven 
asynchronous I/O is also a pain in
any *nix system.   The GUI..how this is writtem, depends on which 
desktop is being run. GNOME or
KDE or Novell's Xglx or any number of more obscure desktop environments. 
All of which require
the GUI to be built on them in order to take advantage of each ones 
libraries. Or at least have the
correct version of these libraries available to run the GUI. That is 
unless you write the GUI with
Athena widgets only. (Yuck )

Yes I would say to get the SDR code to run have ways decently under 
Linux, the Flex guys  definitely
have their work cut out for them.

Sure surprised the out of me, thats for sure.  I got a call on

"He. You won the Big Ony Buddy" and I said OK... What is it ??? Anyway 
you are
right, it is a lot of fun. I can hear, even through the ciaos of a DX 
pileup, even weak
stations. And I only have a horizontal loop up about 30 feet. (I'm a 
"Clif dweller"
as it were.)

[Flexradio] New Bee

[Chris Maukonen]

Well I finally got my SDR-1000 on the air. (I won it at the Orlando 
Hamcation). My
first impression. Receiver is like WOW. My previous set up conswisted of 
an IC R75/
IC 718 in transceive configuration. There is just nor comparison. 
Pileups no longer sound
like noise and I can hear station I could not before.   Not to difficult 
to set up, but took my time.

I do have another PC on order that will be used specifically for the 
SDR, but it won't be in
for a couple of weeks.


Some thoughts after reading the list. First I like the idea of 
separating the DSP code from the
GUI. In fact I like the idea that some one put forth of even having it 
on its own single board PC
along with dedicated AD/DA designed for this use, like the folks at 
HPSDR are doing. Then
writing the GUI in some higher language such as python, perl or even 
TCL/TK.  This way
you would not have to think about whether the sound card used is 
supported. FYI linux Firewire
is currently only supported by a  libraw1394 for a limited number of 
devices.

I do find the latency in the xmit audio (delay) to take a bit getting 
use to. In fact I do not
use the built in monitor. I have my mic going into a Yamaha mixer then 
into the SDR, it also goes
into another mixer that I have my PC attached to so I can monitor over 
the headphones I use
to operate with.


I like the current GUI but some sort of scripting to personalize it aka 
"Skins" would be nice,
but no necessary. Also some slider or some such the change the filter 
skirts would be nice.
I do not necessarily want sharp skirts all the time.

Well that's it for now.


Chris
