Re: [Flexradio] Power SDR / Kubuntu

[Jimmy Jones]

It's very simple to have and keep an XP machine up and running. 
I find it utterly amazing how many people can't make it happen. 
I've had my flex since early 2005 (sdr1000) and have had few problems
running it. The radio has always used the same computer. (2002 dell
4550)I've run the same computer with the same operating system until
last year when the hard drive finally crashed on it. Nothing was lost of
course because everything was backed up. I installed a new hard drive
and its all back up and running again. This computer has run every
powersdr version since 1.6 and 3 different sound cards. I'm not picking
on you but I can't see the need at this point to move to a different
operating system. Most likely those having problems with XP would have
problems with Ubuntu too. Would you be interested in selling your 5000?

I have what is probably one of the first Flex 5000A's made, and would
LOVE to use it, but every time I thought I had the computer back up and
running under Windows, it would crash and be completely inoperable!  I
got so fed up with Microsoft that I installed Kubuntu on my computer for
an operating system.  My computer now works, but I can't use my Flex
5000A!  Common' guys, MAKE A Power SDR for Kubuntu  Probably any
Linux version would work with my computer, but I really want to use my
Flex 5000A and can't !!!

[Flexradio] Frequency Stability SDR 1000

[Jimmy Jones]

I’m looking for a solution to the frequency stability problems with the
sdr 1000.
(Dudley did you find it?)
Anyone have a known good highly stable working device for sale?
I’m in the market.
 
Thanks,

Re: [Flexradio] TX Audio Quality Help, please!

[Jimmy Jones]

Are you talking about the distortion that's inherent in the 5000 ? 
I've heard that it's a problem with the DAC in the soundcard.
I don't believe the 5000 will be an audio aficionados radio in it's
present state. 

The 1000 doesn't seem to have this problem (at least not with the
firebox or fa66)
I've seen guys with 1000's run computer mics and make them sound like a
million bucks.
You can't do that with the 5000.

[Flexradio] Problem with 1.12.0

[Jimmy Jones]

Has anyone had 1.12.0 switch frequency or bands while transmitting? 
While talking on 75 meters the other night I had 1.12.0 do this to me.
I immediately think RF Problems so I switch to my old trusty Beta 1.6.3
and never see the problem with 1.6.3. I talked for hours with no
problems.
I've never seen this problem with any other program version.
This was running an SDR 1000 and amp at 1500 watts PEP out.

Re: [Flexradio] SDR1000 Edirol FA66 - echo on transmit

[Jimmy Jones]

If your running some of the newer soft ware make sure.
Audio  buffer size is 1024 or less
DSP Buffer size on transmit is 1024 or less
If your running older software without the split transmit recieve buffer
size set to 1024
These setting will work without latency on a firebox or a fa-66 souncard
running in 96k mode in SSB
In General Options make sure you are running in Real Time if possible
To test for RF into the audio chain just turn your power all the way
down and then key the radio and talk.do you have latency? If you do
it's not rf feedback..If you don't gradually increase power to the
level that you start having latency to prove feedback
If running a fa-66 sound-card  set the Start, Control Panel, Edirol
FA-66 to buffer size min.

 There is a latency (delay) between what you

 on CW) and what goes out on the air.  Most
 reports of echo turn out to be RFI.  The
 transmitted signal is picked up by the
 microphone input slightly behind your speech
 and is an echo of what you just said.
 I'm guessing that higher gain in DX or
 Compander is revealing the RF pickup.
 
 If you have a second receiver, try transmitting
 into a dummy load and listen on the second
 receiver.  Then compare with transmitting
 on your antenna.

audio without EQ


Greetings all,
 
A couple of days ago I used my Heil PR20 to record a voice over for a video
I was working on. When I played back the recording I was shocked to hear how
clear and natural my voice sounded with the PR20. There was no EQ or
processing applied to the audio, just the mike plugged straight into my
Edirol FA66 sound card and played back into a decent pair of computer
speakers.
 
The same mike when used with my SDR-1000 does not give anywhere near the
same results. Without heavy equalization using PowerSDR I have been
described as sounding like pillows were placed over the mike. I was thinking
that perhaps this wasn't a good selection for my SDR-1000. After hearing my
recording for the voice over I'm thinking differently. Isn't it the job of
the microphone to reproduce the sound as close as possible to the source as
it did during the recording? I figured as a baseline my SDR1000 should sound
clear without muddiness before equalization is applied. The EQ in my view
should be used as an enhancement to the audio or in certain cases to make up
for the deficiencies of a poorly designed microphone. So, my mike appears to
be more than adequate for audio applications, why does it require massive EQ
to sound decent as a transmitter audio source? Does it have anything to do
with transmitter bandwith, etc?
 
I'm thinking of purchasing the W2IHY boxes but if I was only able to get the
audio to sound as good as the mike reproduces  it (without EQ) I would be a
happy camper. Still love the radio, though!
 
Any thoughts?Edwin MarzanAB2VW

Re: [Flexradio] AGC

Google this: A discussion on the automatic gain control requirements of the
SDR 1000. I think you will find any answer to your question in there.

 

Assuming your on SSB???

Try these settings:

AGC to slow position

AGC-T to 40 

These are night time Texas (high noise) settings that I've found for years
to be quite.

If you get blasted with these settings on SSB, you have a problem somewhere.

Talking on 75 meters right now.
AGC-T @ 40
AGC set to Slow
Pre-amp set to high
If I don't look at the meter, I can't tell the difference in peoples audio
if I don't look at the signal levels on the meter which when I look are
varying more than 20 db .

The band is very very noisy with your settings here in Texas.
It's very melodious and quite with mine.
Do you guys actually ever use your radios?

Rob,

One of the great things about PowerSDR is that you can so easily adjust 
the AGC threshold to accomodate band conditions. Remember though, the 
lower the AGC-T setting number, the less the AGC will be compressing the 
audio gain, therefore, the greater the audible difference in amplitude 
between weak and strong signals, and the lower the background noise 
between signal peaks.

If you increase the AGC-T setting to something more like 75 or 80, the 
effective audio gain compression is increased considerably, (at the 
expense of hearing more band noise relative to signal levels), and the 
differences between weak and strong signals will become much less. 
Overall it's a noisier listening experience, but you won't be jolted by 
the big signals.

Re: [Flexradio] Echo in MON

[Jimmy Jones]

Richard

Are you running the maximum sample rate for your soundcard?
Ie: 96000 as opposed to 48000 in my case

Are you running the minimum amount of buffer size that you get away
with?
Ie: 512 or 1024 as opposed to 2048

Are you running your process priority in real-time?

Are you running with your latency (ms) checked?
I think I was told at some point that with this not checked it was at
minimum latency. I don't know if that is true or false. I leave mine
un-checked. 
That's everything I can think of without going into the computer setup.

Subject: [Flexradio] Echo in MON

This is my second pass on this issue: I still have an echo when I MON. I
must be the only one who has this problem since I haven't had a response
from anyone else who has experienced it.  I've fiddled and twisted every
switch that I can think of in the setup and with the mixer. I've also
messed
with the system sound settings in XP with no change.  I THINK the shack
is
pretty clean on RFI running barefoot.  I get the echo on dummy load and
either of the two antennas I have at every power setting form zero to
100.
I did have something similar happen with the 1000 when I would
inadvertently
have multiple sound cards running.  

 

What am I missing?

 

Thanks,

Richard, WU5K

Re: [Flexradio] Heil Headset/Yaesu Connector Assembly

[Jimmy Jones]

I've never had an on the air audio problem that I couldn't hear in the
Monitor on my sdr1000. Resist the urge to turn the mic gain up too high
and or turn the comp or cpdr up much above 5 or so. The meters(sdr
output)will appear to be low on rf output when it is actually not. (ssb)
With my condenser mic going straight into the firebox I don't have to
turn the mic above 30 with the firebox gain at 50%. If the mic gain is
set too high with the comp turned on and a really narrow bandwidth the
output does sound kind of buzzy. Are you listening to your monitor
through head phones? If not the monitor gain may be up to high (just low
enough to not cause a squeal) and it will feedback into the transmit
audio chain and cause problems. 

Good Luck with your problems

Rob,

I am going to jump in the middle of this thread to say that the 
process priority that is in the PowerSDR Setup is just the same as if 
you went into Windows Task Manager,  highlighted PowerSDR.exe 
process,  right clicked, Set Priority.This gives PowerSDR a 
higher processing priority (compared to other programs)  so that it 
might overcome or jump ahead of other lower processes.  Helps if 
there is something else causing issues..  Sometimes programs and 
devices creates a process, that has been rendered useless and is just 
hanging around and not needed,  or has a long delay before being 
serviced or complete a task.  The ethernet NICs are bad about this as 
is USB NICs, this is one reason why when DXLabs (email programs, WEB 
browsers, CAD programs, etc)  is calling for a spot, and it's servers 
respond, there is a long delay and this is what causes the occasional 
pops..  Don't use the ethernet, stop firewalls and Spam filters,  it 
all runs much better,  but this is not piratical,  so upping the 
priority will help,  you can also lower others..

Now where is that Quad Core??   HI   HI

Hope this helps,

  Hi Peter,

I've been following this discussion with great interest.

Can you shed any light on how the options in (PowerSDR Setup  General

Options  Process Priority) relate to overall performance including the
low level buffer utilization etc,   Also how it affects PowerSDR
processes relationship to other none PowerSDR processes?

I have PowerSDR running more smoothly (no pops or dropouts) since I
upped
it's Process Priority to Above Normal though I have no idea why.

My buffer size is 4096 with a sample rate of 192kHz.  (~50
interrupts/sec?)  Normally, I would think increasing the buffer size
with
a given sample rate would decrease the number of interrupts and DPC's.
Thus as the sample rate goes up so should the buffer size  (to decrease
OS overhead.) Yet the larger the buffer the longer it would take a
given
speed CPU to process it increasing the process latency.  (Though I'm
sure
it's not so simple.)

To confuse matters I also have DXLabs running.  The only CPU intensive
DXLabs operation is a sort function when a new spot comes in.  CPU
utilization ranges from about 17.5% to a to an occasional high of about
60%.  Normally (90% of the time) CPU utilization ranges in the 15% to
20%
range.

Thanks in advance for any insights,

  I'm sorry to have to correct this again, but DPCs are most certainly
  not
  entirely a hardware based phenomenon.  They're entirely a driver
  based
  phenomenon.
 
  Your note started by talking about ISR (interrupt) latency.  But in
  this
  case you're talking about DPC-to-ISR latency.  I'm sorry, but these
  are
  different concepts entirely.
 
  DPCs are simply callbacks from the OS to a driver, to allow that
  driver
  to perform some less-than-time-critical processing while the OS
  remains
  entirely hardware interruptible and (almost always) before returning
  to
  user mode.
 
  While DPCs can add latency TO OTHER DPCs they can NOT contribute to
  hardware interrupt latency (unless interrupts are disabled on the
  device
  in question while all or part of the DPC runs, which would be a
  broken
  design for a driver that supports having multiple requests
  outstanding
  simultaneously).
 
  The whole idea of using DPCs in Windows is to help keep interrupt
  latency as low as possible, by Deferring (the D in DPC) all but
  the
  most time-critical tasks so that they can be processed with
  hardware
  interrupts fully enabled (and thus not blocking other device's
  interrupts).
 
  I'm not saying that abnormally long-running DPCs aren't a problem
  in
  Windows.  They can be.  If DriverA (your NIC driver, for example)
  has a
  very long running DPC, it is possible that the DPC for your
  Firewire
  card could get stuck behind DriverA's long-running DPC and thus
  experience increased (perhaps even unacceptable) ISR-to-DPC
  latency.
  Note that the problem here is with DriverA and can be avoided by
  (a)
  trying a new DriverA, (b) swapping NIC cards.
 
  
   but how well the hardware driver recovers (and this is very
  subjective, IMHO)
   from long duration DPCs (delayed procedure calls).

Not to mention Mike that Enforcement of this plan would be a nightmare. 
The ARRL and their plan are a joke.
What's wrong with the plan that we have?
I roll around the bands and don't even hear that many stations on the

Particularly when well EQ'd, the fidelity and intelligibility is greatly

second guess what is being said by the other station, as at that
band-pass

Being unsociable is either knowingly transmitting into someone else's
band-pass, or transmitting a broad signal in crowded conditions, both of
which says a lot about the individual operator as opposed to the
bandwidth
he is currently occupying.  Remember, this operator is on a Flex, and

 That band plan is a really awful thing.   Why have a Flex Radio?  The
 plan calls for 2.7 kHz SSB bandwidth and 6 kHz AM (and not much of
 that).  You sure don't need a Flex radio to do that.

 Perhaps we can derail this thing.

 commenced with 2 crystal oscillators @7,100kHz and 7,098kHz.Comments
 1. The main problem of the UA-1ex is the poor sensitivity or the high 
 (internal) noise. The sensitivity control at the LINE IN must be carefully 
 adjusted to exploit the (rather limited) dynamic range. Noise humps appear (+ 
 15dBm above baseline) @ +/- 15kHz of the centre frequency. 2. The UA-1ex can 
 be operated for TX/RX without additional hardware changes to the box.3. 
 Switching to 98k sampling rate is useless for SDR-1000. The UA-1ex operates 
 only in REC or PLAY with 96k.4. Transmit audio no deficencies were 
 observed.Willi - thanks for purchasing the UA-1ex for testing!73s - Klaus,

Re: [Flexradio] Calibrate sound card

[Jimmy Jones]

Can anyone offer any advise on making the recorder work.
I can play back to myself now but I can't play back a recording over the 
air.

 In the official 1.6.2 release where there is an option in the audio tab to

 On a second note...How much latitude does the PA gain by band settings

 OBTW, I am aware of the fried chips from too much audio drive and have no
 need for 100W output, but wonder if we are taking advantage of the dynamic

 for -10dbv input as recommended for the D44 I run, but wonder why we can't
 run more suds (+4) to take advantage of what the sound card is capable of or
 am way off base?

I can remember doing this measurement and getting nearly the same

I can't remember what the answer was but I think you are ok there. Maybe 
the 6.93 was a peak to peak reading rather than a RMS reading.
1.98 vrms wouldn't equal 6.93 pp so.. I just don't remember but I

 Hi Folks,

 I just wanted to let you know about a modification I made to my
 radio.  DC1 is a switch mode converter that provides +/- 15 volts
 for the instrumentation amplifiers IC6/7 on receive that interface
 the QSD to the sound card.

 The DC/DC converter's internal oscillator free runs at ~120 kHz
 and is very rich with odd harmonics, every 240 or so kHz, throughout
 the HF range.

 This manifests itself as low level 'carriers' that drift around and
 through receive frequencies.  When the SRD is first powered up they
 move quite fast, but after the unit has warmed up the move very, very
 slowly through your QSO.

 These signals were about S4 on my SDR1000 in the 40M band and are 
 easily removed with the automatic notch.  But, loving to tinker like I do I
 removed the DC1 and soldered a 7 pin header in its place. I used a
 1 x 2 x 2, +/- 15v linear supply wired to the header.

 How's it work? Great!  No more warbling tones from within the SDR.

 I wish I would have done more before and after testing. Now when I
 connect the receiver to a dummy load, most of the bands are clear of
 spurs with the noise floor at -153 dBm.  I imagine that the fundamental
 waveform (square wave?) of the DC/DC converter was putting an awful lot
 of total integrated power into the QSD and mixing with other signals
 there to increase the total spurs.

 It just keeps gettin' better.

 John

Re: [Flexradio] DC/DC Converter (DC1) Replaced with Linear Supply

[Jimmy Jones]

Cecil,
I can imagine that you sent these e-mails twice so that tells me 
something about you right there.
Oh wait that was probably someone else's fault.
Are you interested in selling your SDR-1000?
I was lucky enough to be able to follow along with Rigs early 
development because of Dudley Hurry late night 3870.kHz.
Dudley must of been one of the first guys to own a radio or at least 
really close.(Top 25 or so I'll bet) That guy is always on the leading edge.
Night after night, he would be in there cutting out and breaking up and 
we all just laughed and went on playing audio with our 850's and 870's 
and what have you.
I was very interested in the rig because I liked playing around with 
computers and I liked the idea of something new coming into ham radio. 
After about a year, I really started to sit up and pay attention. This 
radio was really starting to shape up. It had a flat receiver and 
transmitter and really sounded good (all this was pre-firebox) I think 
Dud had just installed his Delta 44.
I could go on and on here but the point is that your 930S was made by a 
company that started business in 1946. It has many years of development 
work behind it and I'm going to tell you that I'm simply astounded to 
see where the Flex is at today after only a few years. Is it perfect ? 
Nope. Was I smart enough to know that going into the deal? hehehe Many 
would argue no.(AH's) but I knew I couldn't expect a Cadillac 
and I knew that I wasn't paying for a Cadillac either. What were your 
expectations going in? Is it just possible that you or your equipment 
could be some of the problem? Is it possible that you expect to much? I 
have plenty to gripe about Cecil. My radio works just as good or bad as 
I thought it would at this point in the development cycle.I don't really 
try to encourage people to buy the radio simply because it's not as 
polished as a lot of people would like. I have used it on every band 
except for 6 and 160 and it works without problem. I'm just happy that I 
got the best Flex SDR ever made. Don't think for a minute that I don't 
have complaints about the rig. I do. But you have to sit back and put 
the whole situation into perspective. (60 years at building 
radios..vs.. 3 years) Kenwoods first radio couldn't hold a 
candle to this one and many would argue rather successfully I might add 
that the 930 and 940 were turds too. Mark my words, Kenwood if they 
choose to stay to the Amateur Radio Market will go down the SDR path. 
The witting is on the wall. It just a matter of time.

'Never argue with an idiot. They drag you down to their level then beat 
you with experience.' Bayona wrote:
 I'm sorry, I apologize, I got a lemon of a radio, and the manufacturer

 Myself and several others must be imagining this problem, funny thing my 
 other radios don't pick up these moving signals, it's inside my radio.

 Can you possibly imagine that someone else's radio might not work as 
 good as yours without being the operators fault? Maybe, just maybe they 
 got a radio that has something wrong out of the factory?

 Nah, it could not ever happen.

 Duffy,

 Your comments are all correct, but let me comment since I have been
 using the FA-66 for a few weeks now.

 Yes, you do have to set the sampling rate switch in the back, but since
 I have set it at 192K, I have found no need to change it.

 True, it does not come with home audio recording software or a graphical
 mixer, but they are not required for the SDR-1000.  The FA-66 is
 supported by all home audio software packages.  I'd rather spend my
 money on better DACs, ADCs and Mic preamps than on CuBase and a
 graphical control panel.  These I can buy separately.

 The separate headphone volume control is a nice feature, but I over came
 the deficiency by turning down the volume on the speakers.

 Yes, there are gold plated RCA jacks on the back of the FA-66, but that
 is because they follow industry convention of using them with consumer
 level audio (-10dBV) which is an exact match to the SDR-1000.  Also, I
 have never had a quality RCA connector fall out unless it was assisted
 in some way.  By the way, once the cables are installed, there is no
 need to mess with them any more.

 There is an addition nifty feature for this input; a variable gain
 control that will allow you to tailor the input to either accommodate
 strong signal handling or weak signal reception depending on the gain
 level you set.  I have mine set a little towards the weak signal
 reception side of things.

 The FA-66 does have a built in limiter to apply slight compression and
 prevent clipping in the ADC which is a nice touch, keeping the input
 audio clean.

 The mic preamps are very quiet.  My Firebox has a constant 1000 Hz tone
 that is always there.  Repeated calls to Presonus Support to get this
 resolved resulted in nothing but the run around.  Speaking of this, this
 is one of the major reason I do not like the Firebox.  Presonus does not
 stand behind there products unless a vocal majority make enough
 discontent for their executive to do something about it.  Just take the
 hosed up firmware problem and their deafening silence on the matter.
 Roland is a bigger and much more respected company in the audio
 business.

 The other reason I like the FA-66 better, and this is purely subjective,
 is that I think it does not color the sound like the Firebox does.  I
 did some side by side comparisons on RX and the FA-66 is easier to
 listen to and has a more balanced natural sound.

 The FA-66 isn't for everyone and it isn't the perfect sound card
 interface, but it is a big improvement over the Firebox, IMHO.

 There are a few other differences between the Edirol and the Presonus,
 some might like to know about. The Presonus uses a software switch in
 its program to select between 48 and 96Khz and the Edirol uses a
 hardware only switch on it's back panel to set 48, 96 or 192 Khz. The
 Presonus comes with a software mixer application you may use for add on
 things and it also includes Cubase LE audio software,that has high end

 software programs other than driver setups. The Presonus has 2 separate
 output volume controls on front. One for main 1-2 output and one for
 the  headphone jack output. The Edirol has one volume out control which
 controls both the main 1-2 output and the headphone out. Not a big deal
 unless you are running the main out to powered speakers and also trying
 to use the headphone out also. The Edirol  3-4 line input rear jacks are

 RCA phono jacks ( Yuk just like my stereo amp). No detents like 1/4 inch

Re: [Flexradio] Is Anyone Using the SDR1000 as Primary Radio

[Jimmy Jones]

I can't remember the last time I turned on any other kind of radio. Version
1.4 something of the software.
I have an 870 but it just sits on the side and never gets used.
I see something much different when I read post on here.
I see people working together to make the best damn ham radio the world has
ever seen.
I  use this radio every night on 3870 khz. here in Texas. It becomes the
topic of conversation many nights and not because I make it the topic.
It always works and it always hears as good if not better than anything else
on the band and that includes the 10,000 dollar radios on freq.
I enjoy the attention so I don't think anyone else should buy one.

 the reflector for some time.  Granted, the reflector is for the discussion
 of problems, but for someone considering the purchase of an SDR, it is
easy
 to draw the conclusion that the software is simply loaded with problems.

 Is anyone in fact using the SDR-1000 as their primary, every day radio?
Is
 there a release of software that allows the system to be as reliable as an
 off-the-shelf box, ignoring the performance issue for the moment.  It
 doesn't seem to make sense to have a high performance radio if it doesn't
 work reliably.

 Hah!  Reminds me of the folks in Seattle telling everyone how rainy it is
 there all the time.  (The only times I've been there it's been sunny and
 beautiful - so I got a little suspicious...)

 I haven't had any other radio hooked up to my antennae for a long time.
(I
 do use my old Ten-Tec as an on-air monitor, though.)

 I'm using 1.6.3 686 with a Firebox.  (I'm really enjoying the new multiple
 receive sub-rx feature.)

 I think most of the time those of us that are happily using the radio
 day-to-day just spend more time operating and less time talking about it!

 I can't remember the last time I turned on any other kind of radio.
Version
 1.4 something of the software.
 I have an 870 but it just sits on the side and never gets used.
 I see something much different when I read post on here.
 I see people working together to make the best damn ham radio the world
has
 ever seen.
 I  use this radio every night on 3870 khz. here in Texas. It becomes the
 topic of conversation many nights and not because I make it the topic.
 It always works and it always hears as good if not better than anything
else
 on the band and that includes the 10,000 dollar radios on freq.
 I enjoy the attention so I don't think anyone else should buy one.

 There's no harm in advocating more power, but in point of fact, I do

 I even sometimes forget and leave [EMAIL PROTECTED] style programs running,

 I just don't have any serious problems whatsoever.  The most I have to do

  You hardly need multiple cores for this.  I run two or three monitors
  on a fairly vanilla Dell at work with XPpro without much of a
  problem.  Multiple monitor support is more a matter of choosing
  appropriate video cards that have the right acceleration that works
  for the applications YOU want to use (e.g. what's good for 3D
  rendering and gaming might not be optimum for scrolling through
  documents).
 
  I would suspect that for most people, CPU is not the limiting
  resource.  Rather it's something like memory bandwidth and/or size,
  cache size (memory bandwidth in a different form), or disk bandwidth.
 
  Jim, W6RMK
 

 All my experience running the SDR console on a couple of machines agrees
 with this.

Re: [Flexradio] Help! Firebox Problems

 I hate to post this to the Flexradio group but I am getting desperate. My
problems with the Firebox are giving me serious doubts about purchasing an
SDR in the near future. The first Firebox I purchased was DOA. Now the
second one has a serious problem (it was not purchased from Flexradio BTW).

 I called Presonus on Tuesday and started a trouble ticket. On Thursday I
wrote to their tech support. As of today I not received a reply. To say that
I am unhappy would be an understatement. I don't think that I will ever be
purchasing any other Presonus products.

 The problem is this; when I go to Open Volume Control Options
Properties and pick any of the Firebox Line In settings for Adjust volume
settings for Recording there is nothing there under Show the following
volume controls. As of now none of the inputs work. I tried recording
streaming audio (via Sony Sound Forge Audio Studio) and it will not record
anything. However the cheapo built in sound card in my motherboard works
just fine for recording.

 Has anyone else seen anything like this? It looks to me like the inputs
are dead or am I missing something to make them active?

 Any help with this will be greatly appreciated

 Thanks

Subject: [Flexradio] SDR1K for sale perhaps...


 I'm seriously considering selling my SDR1000, as I just don't seem to be
 getting very far with it.

 Since I bought it, it has transmitted for me properly on one occasion.
 I admit that the original problem was caused by my construction
 techniques, which Klaus found and fixed, and the unit was fully tested
 and returned to me.

 I am also grateful to Eric and others who have tried to help me sort the
 problems with my set up, and for organising the DEMI 14428MHz kit for
 me, which I've not yet assembled as I wanted to get the basic SDR1000
 running properly first.  I should have waited for the made up board I
 guess, but I bought mine before they were available.  Ah well, that's
 the way life goes sometimes.  HI

 However, it would be nice to have a radio that I could switch on and it
 worked and, before anyone points it out, the V1.6.2 full release isn't
 working, so it's not a beta update problem.

  Looking at the add on costs for 100 Watt PA, ASTU, plus the Firebox and
 D44, which are now specified as the required cards I think I would
 probably, with hindsight, have been better off saving up for a TS2000X.

 So, keep a look out on eBay if you have a set up that is running an
 SDR1000, you might want another unit as back-up or for spares.  Oh, and
 I have a spare RFE board which is probably OK, as I bought that when I
 was trying to fix my original fault.

I've noticed that the software does not cal wwv properly for some time now,
On my radio it is always been down the band some.
There is an absolute no fail method of calibrating wwv that I've found
through the help of some of my buds.
I use double sideband to manually calibrate and it's a completely fool
proof, dead nuts on the money everytime tuneup.
On my rig I can barely even understand wwv until it's very close to being on
the money.
That's the methid I use.

 the frequency calibration routine.  When I do this I get a pop message
 box that says, Peak is Outside Valid Range.   I don't have this
 problem with 1.6.2.

 I know there is a proper place to report bugs and I know this newsgroup
 isn't it, but I'm not sure where the proper place is.

Re: [Flexradio] Frequency Calibration on Recent SVN's

[Jimmy Jones]

Exactly
Another weird little thing I've noticed when tuning using DSB is in the
phase display mode.
According to which side of center your on the display will move in a
clockwise or counter-clockwise direction.
I think ideally it should be completely stopped and inthe middle of the
display but my rig will not even come close to that. I love this little sdr
though.

 I have had problems before when the signal was not sufficient.  I

 signal would drastically effect the ability for the calibration
 routine to work properly as well.  I wonder if setting the rcve filter
 to a very narrow pass-band prior to running the calibration would
 help, hurt, or not matter at all.  Without looking at the code, I
 haven't a clue.

 Eric; what actually happens there?  What mode, filters, etc., are used
 during calibration?  Are those parameters hard coded, or does it use
 the mode and filters the user has set?

 PS:  I am still able to calibrate just fine with the current svn.

Re: [Flexradio] EQ frequencies

[Jimmy Jones]

Yes Mike,
Start with the Behringer Tube Preamp MIC 2200
Run that into you Behringer Ultra Voice Pro vx 2000 and be sure to set the
Expander to eliminate the fan noise.
If you have noise you just can't get rid of use your Behringer feedback
destroyer 1124p to surgically slice out the unwanted noise.
Next set your Behringer Ultra Q Pro Peq 2200 to these approximate
settings...
Band 1 @80hz, .8 octave bw and boost about 5db.
Band 2 @ 350hz, 1.2 octive bw and cut -15db.
Band 3 Turned off
Band 4 @ 4.6khz, .4 octive bw and boost 5db.
Band 5 @ 6.5 khz, .8 octive bw and boost 5db.
Next, use your Behringer ultrafex pro EX 3200 to give your audio that
low harmonic fm sound and run that into your Composer Pro MDX 2200 for
Compression.
Finally, use your Behringer Virtualizer Pro dsp 2024P for a little touch of
plating and your ready to go.
I can already hear that beautiful Flex Audio

Oh,
If you dont have any of this just set your eq up to cut at 160hz (check the
160 notch) and adjust the rest to your liking.
(Unless you want your radio to sound like a yeasu then uncheck the 160 hz
notch) Boxy Yeasu Sound
With my mic it's
+9 db low
-15 db mid
+ 12 db high
Your settings may vary

Re: [Flexradio] Need Advice

[Jimmy Jones]

I really paid close attention to my meter on the radio last night and most
of the time the power showed between 10 and 50 watts.
On my External watt meter this translated into 100 watts plus. I've been
told that the Bird Pep option does not react very fast. (not as fast as a
scope)
I don't know if this is true or not but it would cause problems. I've had to
plead with many new SDR owners to turn the mic gain down. Most of the time
there issues have been the same as stated here. Low Power. I've found that I
have to set the mic gain at 35 on my rig but with no external equipment
except for the mic it can make it up to about 45 or 50. (Firebox set at
midway on the pot.)

Re: [Flexradio] Crackle on Received Audio...

[Jimmy Jones]

Whats your receiver bandwidth?

[EMAIL PROTECTED] wrote:

The computer I use with my SDR-1000 recently took either a ligtning hit or a
power surge, such that the motherboard had to be replaced.  I've since
rebuilt this machine with a new motherboard, using the original disks,
memory, cpu, Delta44, etc.  It has a fresh install of WinXP Home SP2.

I've done a fresh install and calibration of PowerSDR 1.6.2 and also have
the K6JCA console (July 29 version, I think).

All seems to be well except for the fact that the received audio is
accompanied by an annoying crackle which is very unpleasant to listen to
and was not evident prior to this incident.  The voice or CW audio itself
seems OK - subjectively, the crackle seems to be superimposed on otherwise
good audio.

I made a post-processed wav recording of a CW signal.  On playback via the
computer's on-board soundcard (not the Delta44) the audio sounded clean - no
nastiness present.  I haven't tried a recording/playback of pre-processed
signal yet.

Buffer sizes are the initial defaults for the Delta 44 and PowerSDR.

I'm wondering if I missed some config setup option or if the Delta44 card is
damaged also?  I plan on trying to move it to a different slot on the
motherboard to see if anything changes.

Any ideas appreciated.

 I did a new SDR Console install with all the needed programs. It came up

 occured since I installed the Delta Soundcard) and also VAC
  Using USB to LPT Device
  Have also installed VAC 3.12 (registerd) and
 the ComPort program. ASIO etc.
  I have also installed a second soundcard Audigy

 All works so great, except this strange noise (sound) behaving. Did ever
 anyone see the same thing happen?

That's a terrible way to use an SDR.
At a minimum, I have the SDR and  E-mail running and I'm usually surfing the
internet or looking up a callsign ect. ect. also.  You have to have an
internet connection, right?
I'd go back to my 870 If I could'nt have (at a minimum ) those programs
running all at the same time.
I'm interested in running the SDR on a linux distro. I haven't tried it yet
though.
Is Ubunta the version to go with using the flex? I've used Mandrake and Suse
in the past. At that time I think Mandrake was a French version and Suse was
a German version. I thought Mandrake was much easier to use.

Anyway, good luck with your future Flex Box. I think you will love it.

 I took the easy/chicken way out of installing Ubuntu.  I installed a
 second hard drive to keep all things separate.
 In the past I have installed Suse Linux and Xandros Linux.  Ubuntu is by
 far the most slick I have ever used.
 For my machine, a home brewed Asus A8V mobo with an Athlon FX-53
 processor, I could not install release 6.06 (Dapper Drake) directly
 because of a bug in the install program.  Instead, I had to install
 release 5.10 (Breezy Badger) and then do an upgrade to Dapper Drake over
 the web install/upgrade. The upgrade via the web was a cinch and very
slick.

 All of my hardware is supported without a glitch. I will probably build
 a separate computer for my SDR 1000 which will be ordered probably in
 October (as soon as I get finished paying for the latest semester
 tuition for my youngest daughter). The SDR 1000 computer will probably
 have 2 HDD's, Intel E6600 duo 2 processor, if the processors pan out, 2
 meg RAM, cheap video card, 750 meg Zip drive and DVD+- RW with CD ROM
 with R/RW. Only rarely will this computer be allowed on the net for
 updates. Most updates will be by sneaker net from my other PC across the
 room. There will be no permanent network connection  for the SDR 1000
 computer. It will dual boot Win XP and Ubuntu Linux.

 I will run several digital mode programs and feed them from Dragon
 Dictate as much as I can. For some unknown reason, Dragon Dictate runs
 much  faster on an Intel processor than on an Athlon FX-64. Eric W. also
 wrote me that Intel processors do a better job with CW on the SDR 1000
 than Athlon processors. Given the recent changes in the CW code, this
 speed advantage may have disappeared. I will watch the web and wait.

These guys have been paying real close attention to the flex and they all

Subject: [Flexradio] Short takes


 High Stability Mod now available. Radios shipped after April 1, 2006
 have a thermistor soldered to the oscillator, which greatly improves
 oscillator stability. This modification is available from our service
 department for $75 plus shipping. The early versions of the SDR1K took
 as long as 15 minutes to become frequency stable. The addition of the
 thermistor results in a dramatic improvement; within 1 minute the radio
 is as stable as most radios with high stability oscillators. After 3
 minutes, the oscillator is rock solid.  /John Basilotto /

 John   I would caution you in your use of terms High Stability Mod,
 stable as most radios with high stability oscillators and rock
 solid. I have a late model sdr1k that came with this and I would not
 call it High Stability. Maybe improved stability would be a better
 term. I leave my unit on 24 hrs a day and my room temp does vary about
 up to 20 deg F sometimes (65 to 85 F ). Thruout the day I will check
 15MHz WWV and every so often I will recalibrate because it is off 5 to
 10 Hz and sometimes 20 to 25 Hz (on a hot day),then in the eve when
 cooler I do it again. This is  on RECEIVE ONLY, no transmitting. I do
 not consider this rock solid  or  high stability. It is easily
 managible with the easy calibration routine, but it does drift and I
 wonder how much it would drift if I was transmitting . My other 2 radios
 ( Icom 756 Pro and 756 Pro II ) are rock solid after warm up and do not
 require this frequent calibration. I put up with this because I read
 K2OX 's test of the phase noise and how good this osc., is in that
 regard, compared to some others.
 I love my SDR and listen to a lot of stuff with it and the noise
 reduction  and filters are superb. Wish there was a more stable osc with
 as good phase noise for a reasonable cost.  Duffy NA6MM

All SDR1000s sold after April 3 have the thermistor installed. The radio now
stabilizes after three minutes and is rock solid from there on out.

For those interested inn having the thermistor installed, the cost is $75
plus shipping. More information will be released next week.

Toby,

I don't operate CW very much so I can't add anything about #1 other that
what others have said.

As for #2, I have never had the power jump on me running in any mode.
The SDR1K out 100 watts PEP rain or shine.  Matter of fact with the gain
limiting logic, you really can't over drive it without having to really
work at it.

There is a little frequency drift in the first 10-15 minutes the rig is
on until it reaches operating temperature. I operate a lot of PSK and I
don't ever notice the drift.  Also, Flex is supposed to be putting a
thermistor on the OX to stabilize it a little more, so this should be a
moot point unless you need 10^-4 Hz stability. :-)

FWIW.I have decided to postpone purchasing an SDR 1K due to the
following reported problems.  If I am in error please correct..

1.  On CW the rig goes out of phase periodically
2.  The power output can suddenly jump from 100 watts to 120 to 130
watts
3.  Frequency stability can vary from 15 to 25 hz while transmitting as
the osc heats up (design Flaw?)

Otherwise the SDR 1k seems to be an excellent rig with great potential,
but any one of the above listed issues is a deal killer.

Re: [Flexradio] Issues Remaining

[Jimmy Jones]

Toby

I've never been told that my radio drifts during transmit. I do know that 
If I leave the rig on for about 15 minutes before I start using it, all is 
good. If I turn the radio on and start using it immediately it's about 10 hz 
down the band. This takes care of itself in about 10 minutes. I might add that 
my rig does not have the new fangled freq. fix applied to as of yet so with 
that applied it should be solid as a rock.
   Believe me when I tell you that I talk to a group of guys that can hear 1 hz 
difference in freq. and I test them all the time. I can't personally hear that 
difference myself and I believe that goes for a large majority of hams today 
but these guys can and if my radio was running all over the band during 
transmit they would have said something by now. 
Don't let anyone talk you into not purchasing the SDR because you are really 
only cheating yourself. I along with a lot of other guys gripe about some of 
the things on this radio but we are only trying to drive the project forward. 
This is one amazing piece of equipment that is only going to get better with 
time.

  3.  Frequency stability can vary from 15 to 25 hz while transmitting as

  20 Hz out of 20 MHz is 1ppm, which is pretty darn good for a non-ovenized 
  oscillator.  That's comparable to the frequency stability of my new 
  IC-7000, which is specd as 0.5 ppm, but that's after warmup.

  I don't think the frequency varies during transmit for the SDR-1K (unless 
  you have all the cooling vents blocked or something), but just as the whole 
  box reaches thermal equilibrium after power is applied.

  And, there is an after the fact fix for it (a thermostatic heater for the 
  rock), I believe.


  I would venture to say that it would be impossible to find another 
  reference oscillator with the same phase noise performance that also has 
  better temperature stability, unless you went to an ovenized oscillator.

  So, it's not a design flaw, it's just a engineering design choice among 
  phase noise, stability, power consumption, size, and price.

  Sure, you could build an ovenized oscillator into the system, but it would 
  cost more and consume a LOT more power. I use lots of very low phase noise 
  10 MHz ovenized oscillators from Wenzel, they burn several Watts, 
  especially on initial power up, and they're in 2x2x1 packages to boot and 
  cost a couple hundred bucks each.  That's a far cry from a small DIP14 
  formfactor XO module in an entire radio that costs about a kilobuck.

[Flexradio] Cw Latency Problem Solved?

[Jimmy Jones]

Thanks Man,
I knew it had to be a serious problem because none of the gurus ever want to 
talk about. 
It's better to look good than to feel good.
Monitoring what the circuit is actually doing is the reason I monitor.
I still love the machine though and just can't seem to get off of it and go 
back to my kenwood.
How does kenwood do it in the 870? There isn't any noticeable latency in that 
rig. That's one monitor circuit that's nearly perfect.

   If you want to monitor anything passing through the audio subsystem --

   256 sample buffers / 192000 samples per sec = 1.3 ms latency.
  
   There will probably always be a way to patch signal around the audio 
   subsystem so as to eliminate latency entirely. If you want to monitor 
   what the audio subsystem and signal processing are doing, however, then 
   some latency is always going to be there.
  
   You could provide a secondary digital path through the host computer 
   that used, say, 64 sample buffers. 300 usec isn't bad. But you don't 
   want to use those same 64 sample buffers for your filters, probably. So 
   with minimum latency you won't be actually monitoring the processing, 
   just your input. FireWire systems can likely get the absolute minimum 
   down to around 10 samples. They still won't have passed through the 
   processing in that case either, however.
  
   As long as the audio systems use buffered IO, the latency will never be 
   completely eliminated. As long as you use FFT-based convolution for 
   efficient filtering, the true latency will never be less than the length 
   of the primary filters.

  Most sound PCI sound cards use a PCI transaction to transfer a block of 
  bytes across the PCI bus.
  On most sound cards this is 64bytes. So, with 16bit stereo output, this 
  equals 16 samples per PCI transaction.
  The sensible values for an application to use are some multiple of 
  64bytes for the chunk/period of the entire audio buffer. For low latency 
  one would have 2 periods per buffer.
  Your 256 samples above seems a sensible enough size for a period, with 
  the entire ring buffer being 512 samples.
  With a bit of clever tweaking, (i.e. in Linux) one could pick a 64byte 
  boundary within the period and start outputting samples, and they will 
  reach the speakers, thus not having to wait for the period to end. It 
  would be a sort of buffer TX cut in feature.

  The FFT issue has nothing to do with sound card capabilities, but there 
  is no reason why the FFT window should have to be in sync with audio 
  buffer periods.
  I don't understand why or if FFT is used for CW TX anyway. I would have 
  thought that FFT would only be needed on CW RX.

I suffer from  Hey, I'm on the zero syndrom. Unfortunately these guy can hear

Re: [Flexradio] 80 meter Inter mod

[Jimmy Jones]

I was tuning around the 80 meter cw band tonight and heard a broadcast 
station on 3545 kHz.  I was using a 40/80 m trap dipole for an antenna.  
I checked the frequency on my Kenwood TS-450 and could not hear the 
broadcast station.  I suspected that it was an inter modulation product 
from two strong stations impinging on the front end of the SDR-1000.  We 
have only one strong AM station here on 1490 kHz, so I tuned to it and 
confirmed the programming as part of the inter mod.  I then took several 
try's at the N*f1 +/- M*f2 formula and discovered a strong station at 
5035 kHz  (5035 - 1490 = 3545).  I confirmed the 5035 station from its 
programming, also.  This inter mod was present with all settings of the 
pre amp and with the pre amp off.  When I placed my antenna tuner in 
line, the inter mod went away.  My question is this:  With such a strong 
front end in the SDR-1000, how is this happening?

I'm seeing something weird on 10 mhz wwv this morning. I haven't seen this 
before so I'm wondering If it's not something simuliar to what your seeing. 
Instead of showing me - 0.0 hz it's showing -15000.00 hz. I checked wwv on 5 
mhz and it shows 0.0 hz. I think something is mixing with the 10 mhz signal and 
giving me a false reading.

Re: [Flexradio] Firebox problems

[Jimmy Jones]

Yes Kirb
The latency setting on the Firebob is 1.5 ms.
I forget that I'm the only one using an SDR 1000 that doesnt use CW at all.
Hey, I like psk31...
Those numbers that I gave out have only been tested on ssb.
I forgot to mention too that I run the Process Prority in Realtime.

I wonder if there is a problem with the firewire port.
 What are you using to get the firewire into the
laptop?

I used one dual card that had firewire and USB 2 and
it was a disaster.  I bought a card that had 3 6 pin
ports and it works great

I've just noticed what I'll call an audio spur on my SDR-1000/PowerSDR
beta19 system. That is, there is on the Panadapter display, with spur
reduction turned off, a fixed peak of about -110dbm at about +4.7KHz
from the red line. With spur reduction turned off, it seems to be the
same magnitude and the same place on the display no matter what band or
mode I'm on. It also doesn't seem to matter if the antenna or a dummy
load is attached. Mostly, it is outside the filter bands, but it seems
odd. If spur reduction is turned on, it jumps around with tuning, but is
always there.

 

This doesn't seem to be the behavior of other peaks I've put down to
spurs from the DDS. Any theories? BTW, the primary TV and FM
transmission tower for the San Francisco bay area is literally in my
back yard, no more than 100' away. Overload and IMD theories allowed.

 

Set up:

 

MP3+, Pentium M 1.86 GHz, 1GB RAM (Dell Latitude D810 laptop), XP-Pro,
SDR-1000 four-board stack (no PA), USB-to-parallel adapter, PowerSDR
Beta v1.4.5.19, Elecraft T1, NJQRP Halfer end-fed halfwave thrown out
the window and hung from a tree.

 

Thanks.

Re: [Flexradio] 96000

[Jimmy Jones]

Mine will only work on 48k. 

Firebox and Dell Dimension 4550 2.4 gig proc with a gig of ram.



 
 Before I got a new computer, I could set the sample rate on the audio
tab
 to 96000 and widen the panadapter display.  Now since downloading
version
 18 on the new computer, when I click 96000, I lose all recieve and
hear
 only an oscillating swish across the audio.  I have to reimport a
database
 from an earlier version before sdr works again.
 
 The new computer is a Pentium 4 Extreme, 3.4 GHz, 2Gig, Dell XPS 600.
 
 Delta 44.
 
 What am I doing different/ wrong??

Re: [Flexradio] 160 hz notch

[Jimmy Jones]

160 hz notch helps to remove that BOXY Yeasu sound which this radio does 
have without eq.
I'm running 7 pieces of rack gear through my firebox and it works like a 
champ.
I don't need the notch at all. Having udx and friends help with the eq cant 
hurt anyone either.
That guy has radar ears...and if the flex didnt have the problem in the 
monitor he would have one too.

The short reason for selecting this frequency is that it tends to make the
audio sound boomy which is not desirable for amateur work. It is 
especially

troublesome because  amateurs use only the bottom 3 KHz of the audio
spectrum. You can't compare commercial broadcast EQ preferences with 
amateur

operations simply because we are using different audio spectrums. For
additional information regarding audio enhancements for amateur radio,

Unless I missed something in the manual, there are some hidden keyboard

I think the spacebar repeats the last macro in SDR.
Windows sees it a a repeating key at OS level so it fills the keyboard
buffer quickly. Perhaps there is a method of turning of 'repeating keys' in
windows. I just always found those which are convenient which don't repeat.

Can anyone make a recommendation on a good Firewire to PCI card ? (1394a)
400mbs 
 
I need one to use with my firebox.
 
Computer here is a Dell Dimension with a 2.4 gig Pentium 4 Processor and a
gig of ram.(533mhz FB)
 
I'm beginning to wonder if this is going to be enough computer.
 
Thanks,
Jimmy
