Re: [Flexradio] RIT cleared on click tuning- RTTY problem

[Mark Mumaw]

Larry,
   I'm not sure a fully understand your post. I have to use the XIT/RIT
in a non standard way to overcome a problem the PowerSDR has with RTTY.
I have no problem with clearing RIT on click tune but PLEASE !!! give me
another way to make PowerSDR compatible with the long accepted standards
of RTTY. This standard has been in effect for OVER 50 Years. Every
modern rig with a RTTY mode, displays MARK freq. including the 7800,
9000, 2000, 756, Orion, etc. 

   I don't understand your last paragraph. The third party logging and
DX cluster software I run expects the rigs to use the MARK freq. not the
carrier freq. Every DX cluster reports the MARK Freq on a RTTY spot.
I'm not alone here. I have talked to at least ten Flex owners who
have this same issue. 
PowerSDR already has dealt with part of this issue with the "Click
Tune Offset". I'm asking that it be taken one step further by adding an
OPTIONAL corresponding display offset. Better yet save this option with
the TX Profile. I could then have a different profile for each mode I
might run under DIGL or DIGU (ie RTTY, AMTOR, etc.)
I love my SDR-1000 and have ordered the 5000. It is my preferred rig
for RTTY work. This problem will prevent me from using this rig in RTTY
contest. I could and will go back to an older version for now but that
is not going to be acceptable when I receive my 5000.

Not for me it isn't.

Default behavior should turn off RIT and XIT and not try to deal with
"standard" offsets that change by the mode and, sometimes, by the
station
worked.

AFAIK, there is no common offset between the various digital modes.  If
so, what we have is the best available behavior for digil and digu.

Not clearing RIT has cost me QSOs "in the heat of the battle."  By all
means, maybe a profile can override, but the default behavior should be
agnostic towards shifts and reset both RIT and XIT on click and other
frequency "main dial" moves.

If there's a way to easily accomodate all modes, I'm all ears, but I
cant
think of an easy way to do it.  Third party RTTY/PSK code must also work
with whatever we do here.  If it "sees" something different than we do,
it
isn't a clear improvement for those of us watching two waterfalls.

Re: [Flexradio] Xmit rejection procedure Help

[Neal Campbell K3NC]

In investigating further...

I do not seem to be getting any tone out when I click the "enable  
test tone" box in the image reject dialog. No output wattage is ever  
shown. Is this normal?  If not, any idea what could be the problem? I  
can start the two tone test from the test tab and it outputs fine.

Re: [Flexradio] Xmit rejection procedure Help

[Neal Campbell K3NC]

Thanks, I just tried it at 20 watts and same result. I had also  
inserted the 18db attenuation feature of the Orion2 and never saw a  
difference.  Otherwise, the rig seems to behave normally. I was in  
the DL rtty contest and since I was using AFSK I wanted to make sure  
I was not blasting unwanted sidebands thru my Acom amp (hence why I  
just decided to do the calibration).

Re: [Flexradio] Xmit rejection procedure Help

[Dudley Hurry]

Neal,

The ideal is to minimize the opposite side band..  You may have to 
decrease the signal to the second receiver,  either dropping the 
power from the 1K into the dummy load or use attenuation on the 
second receiver.   You really don't want 40 over on the second 
receiver,  s-9 to 10 over on the same sideband,  then null the 
opposite sideband..   You might be saturating your receiver, and just 
can't hear the null..

[Flexradio] Xmit rejection procedure Help

[Neal Campbell K3NC]

I am definitely doing something wrong!

I have been trying to do the xmit rejection calibration and not  
having much success. I click on the test tone transmit  button, click  
Mox (while in USB), set xmit drive to max into a dummy load and  
listen on the same freq. on another rig. If I tune down abt 3 Khz I  
can hear a tone (past the main tone) but nothing I do with the phase  
and gain sliders has any effect on it.

I tried the procedure in the knowledge base where you set both the rx  
and sdr1k to the same freq in USB, the switch to LSB on the  
monitoring rx. I have an Orion2 and when switching from USB to LSB,  
it does not change frequency (it stays zero beat to the signal). I am  
assuming that this is normally a neat way to shift down freq so you  
can hear any image. Again I can tune downwards but nothing I do with  
the sliders changes any secondary tones.

What am I doing wrong??

Thanks
Neal

Re: [Flexradio] SDR-1000 Fan Noise ( Electrical )

[petervn]

Good try Al,
reminds me on trouble with fans (and fan control
circuits) that I had.
 
IMHO it is advisable to use (aditional) some coils
or ferrite beads in series with the resistors.
 
And a pair of ceramic C's 47nF ..  220nFor so in 
paralel with the electrolitic capacitors to get a 
good low RF impedance.
 
Shield the filter and the wires to the fan.
 
Sometimes it is enough to filter only the + wire and 
connect - direct to a good chassis ground.

Onderwerp: [Flexradio] SDR-1000 Fan Noise ( Electrical )



  I don't know if anyone else has noticed but the fan in my SDR-1000
produces  a wide band buzzing noise in and near the 12 meter band.   See
linked screen shots.
http://www.hamsdr.com/dnld.aspx?id=622 is my sdr-1000 with the fan
running.   The signal can be detected over a range of  +- 1 mhz peaking 
near 25 Mhz. One of the strange things about this noise is that as you
tune across the frequency the amplitude increases as you approach the
peak frequency and then decreases,  but the peak does not scroll across
the panadapter display. ( suspect there may be some QSD common mode
effects when the DDS is set near to 1/8 th the reference oscillator
Frequency. )
  When I replaced the original fan with a different one from another
vendor, the noise was MUCH worse with significant noise on 12.5 and 50
mhz  in addition to 25 mhz. The noise was also detectable one 6.2 and 3.1..

 So I went back to the original Flex fan and installed a RC filter .
http://www.hamsdr.com/dnld.aspx?id=623 is my SDR-1000 with the filter
installed and fan running ( The picture is identical to my screen shot
with the fan disconnected.

The third link is the filter that I installed.
http://www.hamsdr.com/dnld.aspx?id=624

As a side effect of installing this filter, the 0 I.F. hump ( center of
screen with 0.5x) is reduced in amplitude and width on all frequencies.

[Flexradio] RIT cleared on click tuning- RTTY problem

[Mark Mumaw]

It appears that a recent  change has been made to automaticly turn off
RIT when click tuning. I can see how this might make sense but it is a
REAL problem with how many of us have to use RTTY on the Flex. It is my
convention that the displayed freq. is the mark freq. not the carrier
freq. Every other rig I know of displays the Mark freq when in FSK RTTY
mode. To compensate for this on the Flex I've been setting both the RIT
and XIT to 2125. The problem now is that RIT is turned off every time I
click tune. 

 

The preferred solution to this would be to provide a display offet freq
for but DIGL and DIGU similar to the "Click Tune Offset" provided under
the General>Options setup screen. An even better solution would be to
tie this and other parameters to the TX Profile or create a "Mode
Profile".  I already use a RTTY TX Profile to set lower Drive and Tune
power levels for the RTTY mode.

 

 

Thanks and 73's   Mark NU6X

Re: [Flexradio] tune steps

[Dudley Hurry]

Bill,

Are you tuning the radio to each signal?   I know with MixW,  I have 
the rx and tx opened up to about 4kHz and snap tune within the 
waterfall. Maybe I am not covering enough frequency,  but if I see a 
strong signal outside of that I just snap tune the radio to get close 
and fine tune with the waterfall display..  It would be different if 
I was running true FSK instead of AFSK..Just the way I do it..

[Flexradio] tune steps

[FireBrick]

Now worked 2 rtty contests and 1 cw contest.
Also many rtty and cw qsos during week.

Tune steps are too fast at 10Hz and too slow at 1Hz.
Especially in rtty where tuning is so critical and in contests must be done 
quickly.
We need a 5Hz tune step.

And...a 'Snap to Mark' feature for RTTY

I find that the 0 Beat works...if you hit it on the mark.

Cross hairs work well on strong signals that have a nice visible dip between 
mark&space
But weak signals are another matter, much tougher and even more critical to 
get the tuning right
VAC works well and Writelog or WinWarbler decodes well, no problems there.
So copying the signals is good.

When 'running', I normally transmit on vfo b and tune stations who reply 
slightly off frequency on vfo A on my Yaesu. This gave me a BIG dial to turn 
and tune easily.

I'm still trying to find a 'smooth' way of doing this with the flex. Rit is 
too slow and you must move mouse from Writelog to PWSDR to do that.
One way would be to allow the Griffin to operate the XIT/RIT.
Setting the Griffin to 1kc steps would allow left hand to tune and do 
keyboard and right hand for mouse grabs of calls & sn.

I'm open to Flex Contester suggestions.

This might be a good time to re-discuss computer requirement vs.
trade-offs of sampling rate and buffer size.  With my bare 3GHz Pentium D
and 2 GB RAM coupled with Ozy/Janus:  with 19200 rate and 512 buffer, I
only occasionally get a computer generated POP and full sweep bandwidth
with 31% CPU;  With 9600 rate and 2048 buffer I get reduced bandwidth with
20% CPU.  All with steady SAM or AM signals.  So far I haven't been able
to tell difference in audio output and I haven't checked on latency.

Obviously faster is better with latency, longer buffer is worse for
latency, longer buffer is better for filter characteristics.  I may have
missed formal discussion of this as related to the commercial boards or
Ozy/Janus.  Can anyone add a bit more formality to this?

[Flexradio] SDR-1000 Fan Noise ( Electrical )

[Al]

  I don't know if anyone else has noticed but the fan in my SDR-1000 
produces  a wide band buzzing noise in and near the 12 meter band.   See 
linked screen shots.
http://www.hamsdr.com/dnld.aspx?id=622 is my sdr-1000 with the fan 
running.   The signal can be detected over a range of  +- 1 mhz peaking  
near 25 Mhz. One of the strange things about this noise is that as you 
tune across the frequency the amplitude increases as you approach the 
peak frequency and then decreases,  but the peak does not scroll across 
the panadapter display. ( suspect there may be some QSD common mode 
effects when the DDS is set near to 1/8 th the reference oscillator 
Frequency. )
  When I replaced the original fan with a different one from another 
vendor, the noise was MUCH worse with significant noise on 12.5 and 50 
mhz  in addition to 25 mhz. The noise was also detectable one 6.2 and 3.1..

 So I went back to the original Flex fan and installed a RC filter .
http://www.hamsdr.com/dnld.aspx?id=623 is my SDR-1000 with the filter 
installed and fan running ( The picture is identical to my screen shot 
with the fan disconnected.

The third link is the filter that I installed. 
http://www.hamsdr.com/dnld.aspx?id=624

As a side effect of installing this filter, the 0 I.F. hump ( center of 
screen with 0.5x) is reduced in amplitude and width on all frequencies.

Re: [Flexradio] Feds snub open source for 'smart' radios

[Mike Naruta]

Ah, if we behave, they won't take it away from us.

It's the same as before.  Transmit out-of-band
and you're in trouble.  Very fair.

It behooves us to be careful with our SDRs.



BTW on hamsdr.com you'll notice three medium power,
general coverage HF transceivers in our shack.
These have only transmitted on amateur and MARS
frequencies.

Re: [Flexradio] Feds snub open source for 'smart' radios

[Gerald Youngblood]

The good news is that amateur radio is exempted.  The following is the
applicable section of the rulings:

FEDERAL COMMUNICATIONS COMMISSION

47 CFR Part 2

[ET Docket No. 03-108; FCC 07-66]

 
Cognitive Radio Technologies and Software Defined Radios

AGENCY: Federal Communications Commission.

ACTION: Final rule.


6. In regard to MSS' request for clarification about the regulatory 
treatment of amateur radio equipment, the Commission did not intend to 
impose any new certification requirements for amateur radio equipment 
in the Cognitive Report and Order. External RF amplifiers that operate 
below 144 MHz that are marketed for use with amateur stations will 
continue to require certification before they can be marketed. Other 
amateur radio equipment, including equipment that meets the definition 
of a software defined radio and that has software that is designed or 
expected to be modified by a party other than the manufacturer, will 
continue to be exempt from a certification requirement. However, as the 
Commission noted in the Cognitive Report and Order, certain 
unauthorized modifications of amateur transmitters are unlawful. It may 
revisit the issue of the certification of amateur equipment with 
software modifiable features as identified above in the future if 
misuse of such devices results in significant interference to 
authorized spectrum users.

[Flexradio] Re Calibration

[jcharley]

Just curious.
How often do you do a RX recalibration and a TX recalibration?
After every SVN update?
