I connected to one of the Winmor servers a few times after resetting the 
database and it seemed to work fine with the default settings (10ms 
latency). I didn't see any difference by reducing the buffers / 
sampling, but I'm sure it makes a difference.


Thanks again Brian

about 10ms.



I guess the necessity to reduce the buffer size would depend on how
fast the computer is.



No.

The size of the buffers determines latency no matter how fast your
computer is. It has to do with sampling. If you are doing 48,000
samples-per-second and you have a transfer buffer that is 2048
samples long, it is going to take the radio 42.6ms to fill that
buffer with samples. Now if that is the transfer buffer (set in the
Setup>Audio>primary page) it means that it is going to take 42.6 ms
before the firewire driver fills a buffer and transfers it to
PowerSDR.

Now you also have the DSP buffers. If they are set for 2048 the DSP
is going to take another 42.6 ms to process that data. We are now up
to 85ms in the receiver (or transmitter) and we haven't done anything
yet. Note that these numbers are cut in half for a 96kHz sample
rate.

Now, if you set the buffer sizes to 512 the time in the buffers is
reduced by a factor of 4. So for a 96kHz sample rate and 512 sample
buffers, the time in the buffers is 5.3 ms, a much more suitable
delay.

I have no problem running Winmor with the default buffer settings and
10ms

latency so I guess I can assume my system will handle a TNC in
Pactor mode with a few adjustments.



You might find that you are on the thin edge of Winmor working.
Double check your buffer size values.



How did you wire the TNC to the rig Brian? Does the audio run
through the Flexwire or the RCA connections?



On the 3000 and 5000 I am running audio in/out via the flexwire port
with a separate connection coming out to an RCA plug for PTT.

I know that, in the case of PACTOR, there is a worst-case end-to-end
latency of about 110ms. That means that the accumulated switching
time for the radio, latency in the radio, and then the time for RF to
propagate from transmitter to receiver, must be less than 110ms.

Regardless, I am successfully running PACTOR-III with both my F5K and
F3K. I just haven't tried with my 1500 yet.

Re: [Flexradio] VU5K further delayed?

2010-10-30 Thread Greg Jurrens
Alan:

No further delays.  As with any new production, we don't go from zero to
100% all at once.  We have shipped units and are modifying additional
customer FLEX-5000A units in the lab.  Additionally, our manufacturing
partner is spooling up to begin production/shipping on new FLEX-5000A/VU5K
units.

Regarding pricing, I decided that since we weren't moving at full speed yet,
I would delay the price increase until Monday 11/1.  The change to
Production pricing will occur then. (HINT HINT for anyone still on the
fence!)

Lastly, I'm not a software developer but as the "Project Owner" for the
PowerSDR 2.0.x formal release, I'll let you know our dev. team is working
hard to our release plan.  Internal iterations such as the 2.0.13 that you
mention are completed and then sent to our internal test team.  New features
are tested, bugs are identified, and regression testing (across OS
platforms) is completed.  When we are satisfied that an iteration is stable
enough for wide area beta testing, it's posted on the download area of the
www.flexradio.com website and a notice will be made on the FlexEdge
reflector.  FYI, there have been almost 5700 downloads of the last 2.0.8
beta.  The feedback from our intrepid FlexEdge group has been invaluable.
 Thanks to all for your participation!  When we complete the process of
development, internal, and wide area beta testing, FlexRadio will post a
stable 2.0.x formal release to the Main Download section of the website.

Alan, I hope that answers your questions.  Just a reminder that the proper
place to discuss non-stable software issues is the FlexEdge reflector.  For

Be sure to turn off Mini-Deluxe so it doesn't use the PowerSDR's COM ports

Go to the fldigi web site (http://www.w1hkj.com) and select the 'rig.xml
files' link. (http://www.w1hkj.com/xmlarchives.html). In there you will find
a link for PowerSDR. Be sure you right-click on it and do "save link as ...'
and save the file to fldigi's "rigs" folder.

Subject: [Flexradio] Flex-3000 freezing up on transmit

Hello all,

I have been fighting a problem with my Flex-3000 setup (or one that it is a 
victim of) which I believe... is related to RF getting back into it and 
freezing it up (Problem: display wave form freezes on transmit after 
modulation, Flex-3000 requires a power cycle/PSDR needs to be restarted on my 
notebook PC). 

At first I thought it was a problem with my firewire card and all that, but 
eventually got to try transmitting into a dummy load and under this scenario 
the rig does not freeze up when transmitting (all the way up to full power 
out/100w).

Other details:

* 50¹ of LMR-400 feeding a Radiowavz OCF DX 80 ( replaced RG-8X with the
LMR-400 as part of my debug process here)
* Insertion/use of an external tuner does not seem to change the symptoms or 
prevent freeze up
* Increasing output power (and Mic gain to drive it) beyond a few watts into 
the antenna causes it to crash
* Problem seems to be worst on 40m, but I have had it crash on 20m as well.
Higher bands seen less prone to crashing

Grounding:

I have been trying different grounding things but to no avail. I DO NOT 
currently have a 8¹ rod handily pounded into the ground nearby. I have tried 
the incoming copper water pipe in addition to normal A/C house ground (I also 
tried a 50¹ run of RG-8x to that incoming water pipe, with the C/S shorted on 
the pipe end and a .01uf ceramic cap between the center and the shield on the 
other end, where I then connected the center to the GND on the Flex-3000).

Other rigs:

Prior to purchasing the Flex-3000 I have been running my FT-897D into this same 
antenna setup with no known (or detected) issues related to ground or RFI, etc.

Thoughts? Ideas? Theories? What am I missing here? Is there anything in the
Flex-3000 that maybe is futz in some way that would make it hypersensitive to 
some RF(???) in the shack? Or am I missing some other angle here?

Thanks in advance,
Russ, KF1K

Re: [Flexradio] Flex-3000 freezing up on transmit

2010-10-30 Thread Jim Barber

Hi Russ,

I love OCF antennas, (I have one in the air here and one I just finished 
building a balun for another) but one thing they are NOT is symmetrical. 
Because of that and the fact that they are usually fed with 4:1 
voltage-mode baluns, the outside of your feedline is probably crawling 
with those pesky common-mode currents. (both TX and RX, but TX is your 
problem of the moment) Grounding the shield of the coax would only be 
effective on a single frequency, and then only if you knew where the 
nodes were on the feedline.


The thing that actually works for me is stacking lots of Mix 31 
Fair-Rite ferrite beads on the coax. In my case I have two stacks of 10 
Fair-Rite 2631102002 1/2" ID Mix 31 beads, one on each end of the coax. 
(If anyone wonders why I bother with the stack at the antenna I'll 
explain separately) Note these are NOT "snap-on". Snap-on beads are more 
convenient, but I don't care for them. If that's the way you want to go, 
though, the Fair-Rite part # is 0431164181 .


** NOTE: If you're going to use an amplifier, don't go with a small 
number of beads. If the choking impedance is fairly low the beads will 
heat up. You can get the per-bead impedance at a given frequency from 
the Fair-Rite data sheets.


One of the best and most reliable places to buy beads from is Mouser 
Electronics. You can find them by the Fair-Rite number using the 
Fair-Rite number, or:


Solid bead: 623-2631102002
Snap-on: 623-0431164181

My .02, at least...

[Flexradio] VFO Knob

Personally I wouldn’t be without my Shuttle-Pro2, it may offer some tiny 
resistance but I prefer this to a spinning VFO experience. Each to their own. 
Also there are 14 buttons which can be assigned to PowerSDR keyboard functions. 
I use the Controur Powermate for filter width it lends to that function nicely. 

All the best,

I too really wanted a VFO knob for my Flex.   Here's one I found that looked
very cool.

On the order of the Pegasus Tuning Pod.   Kind of pricy, but what the heck.
Anything for a new toy in the shack..

[Flexradio] VU5K further delayed?

2010-10-30 Thread Alan NV8A
Has there been a further delay in the production and/or installation of 
the VU5K modules? I've seen only one report from someone whose rig has 
been upgraded, and the Flex Web site still shows the promotional pricing 
that was supposed to end on October 15?


If there is a delay, is that due to a newly discovered hardware problem 
or to the bug in PowerSDR 2.0.13?
