[Flexradio] SSB Audio Issues

[HARVEYWIZBANG]

I have found that the 8 pin connector even when  wired per the manual is 
more susceptible to RFI than the 1/4" rear connection  for whatever reason.  
Even though this is a balanced input it will work  just fine with and 
unbalanced microphone provided that the "mike boost" is  checked in the menu.  
I 
have used an inexpensive Radio Shack mike with  a long cable with a standard 
1/4" plug into the rear input with satisfactory  results.  Currently using a 
Heil GM5 (unbalanced) with PTT switch wired  with a 1/4" plug for the mike 
connections and the PTT conductors terminating  with a male RCA to the PTT 
RCA on the back panel.  Works fine.   Routinely receive unsolicited commentary 
audio reports.

"What will happen if pins 5 (chassis Gnd) and 7 (mic ground) are connected 
together?"

A temporal rift will occur swallowing the entire universe down to a singularity 
point.  The mother of all black holes.

Seriously, the audio will distort.  There are mic (+) and mic (-) pins on the 
connector.  Mic(-) should *not* be tied to ground (pin 5).  I am purposely not 
calling mic(-) or pin 7 "mic ground", because it isn't at ground potential.  

This is the classic "pin 1 problem.  The mic cable shield will pick up RF and 
if that is connected to mic(-) it will be coupled into the audio circuitry 
creating noise..

Someone else mentioned that the cable shield has to be connected to the body of 
the Foster connector. What is the purpose of this? I'm currently using a Shure

it works fine.

Re: [Flexradio] Finding Noise

[mchasse]

Well the best way to get a Utility company that does not want to fix their 
problems to get moving, is to file a complain with Laura Smith (Special 
Counsel) with the FCC.  I had a problem with my local company and they would 
not fix anything, until they got a letter from her with a 30 day deadline to 
correct the problems, before the fines were imposed on the company.  After 
that, they were working overtime to correct the problems.

I work for a large electric utility as an interference investigator. I make
my living finding all sorts of powerline-based and non-powerline based
interference sources. This is the Flex Radio reflector and not an
interference location list so I will try to be brief. 

 

I realize that my comment here won't stop the practice of whacking, kicking,
bumping or tampering with utility equipment but I am compelled to say this: 

 

Don't tamper with utility equipment. Resist the urge to take baseball bats,
sledgehammers, etc to any utility pole. It's both dangerous and illegal. 

 

You do not have the right to do anything to a utility pole. How would you
feel if I, as the utility's interference investigator, came to your house
and whacked your tower with a sledgehammer? I'm sure you wouldn't appreciate
that nor is it legal for me to do so. 

 

It's dangerous because one good whack could jar something loose and hit you
or, worse, injure you. I work with line crews quite frequently to correct
problems that cause interference. There is only one circumstance where a
hammer is used on a pole. Staples are hammered in to secure the bond
(ground) wire that runs down most poles to ground rods buried under the
pole. When line crew members hammer a pole they do so only after verifying
that nothing will fall on them.  Hydraulic tools are used to tighten nuts
but again only when it is deemed safe to do so.

 

In my experience, whacking a pole rarely produces any useful result. Real
direction finding yields the fastest results. Transformers are rare
offenders (at least in my area.) Loose hardware, faulty lightning arrestors
and broken bond (ground) wires are the most frequent offenders. When the
interference can be heard at VHF frequencies, the source is usually easy to
locate. When the source can't be heard above 7 or 8 MHz, it becomes more
challenging and often indicates a faulty transformer. Still none of my
direction finding techniques include kicking, whacking or jarring
equipment.at least not without a hard hat and a qualified eye. 

 

Seek the assistance of the utility. Try to work with them to DF the source.
Leave the whacking, shaking, tinkering and other physical effort to
qualified line crews trained in doing such work safely. If the utility is
unresponsive or too sluggish in resolving your issue, contact your state
regulatory agency to "motivate" them to focus their efforts more
effectively. 

 

Merry Christmas and Happy New Year to all!

Thanks to all who have suggested other things to look at for as sources 
of noise besides the power line.
 
 Two winters ago I had some noise that only occured on very cold
nights. I suspected a bad power transformer atop a pole. The problem was how
to identify the pole it was on. I'd like to share the two tricks I used.
You'll need a baseball bat.
 
I went down the block listening with an AM radio. When the noise increased I
whacked each pole with the baseball bat. When I hit the 3rd pole the noise
immediately changed. The vibration caused the pole to vibrate which
transfered into the transformer. A crude microphone! I also noticed a "red
light" atop the transformer which I later learned was an "over-temp"
indicator. When I called the local power company they agreed to check it.
Two days later, no more noise! I received a call from one of their engineers
who was amazed to hear how I found it. He commented that they had a $10K
instrument for doing what I did with a baseball bat and an AM radio!

Re: [Flexradio] Win7 Network Backup

[David McKenzie]

I've been using CrashPlan to back up my computers both locally (free, to my
nas) and remotely (pay, to CrashPlan's servers). This method is effective
and automatic, but it is only a "file" backup, not an "image" backup, so you
won't be able to restore your complete operating system from it, just your
important data. It's generally wise to take an image of a newly-installed
operating system so that you can restore the image and then restore the user
data on top of it.

I settled on CrashPlan because they were the only solution provider with
cross-platform support and unlimited remote storage for a fixed price that I
was able to find.

Re: [Flexradio] Questions about antennas and spectral displays...

I appreciate everyone giving such thoughtful answers about the  
spectrum analyzers on modern high-end rigs. I have never built a  
swept analyzer, but I have built hundreds, perhaps thousands, of FFT- 
based analyzers. I thought perhaps I was missing some important  
information. But it doesn't appear to be the case. Right now only the  
various SDR's, the Flex Radios, and the K3 / P3, seem like truly  
modern rigs.

History with MS backup is its always there until you need it, then it cannot
read the backup. I prefer Farstone TotalRecovery Pro or Acronis True Image

I always assumed they were internally using FFT but the 'peripheral'
interface was a sweep because of the speed of the transport between the
radio and the display. Or the power of the dsp chip itself.

I experienced the same disappointment, but discovered Snap Backup. It's

And, it's faster than Windows Backup, small in size, and the backup

ever need to.

Assuming you've decided on Win7 (with which I agree wholeheartedly, but that

decreed that OEMs should use 64 bit as the standard.  32 bit limits you to 3.2 
gig ram, which is a more serious limitation with Win 7 than you'd imagine from 
the old days.  More CPU cores/ threads, and ram of 6-8 gig will give you the

[Flexradio] Which OS for i7 new PC?

[Don]

Steve, WI2W

FWIW - I made the choice to go  to Win 7 -64 bit.  I did this by setting up a 
dual boot system so that I had the choice between Win XP & 7.
I did this because I also tend to keep my systems for a long time and I wanted 
to make sure that all that old software & hardware would work with
the new OS.  At this point I'm glad I did.  As it turns out I had setup my 
amplifier and antenna switch using the DDUtil software and a parallel port card.
So one of the prices I need to purchase was a parallel port card with Win 7 - 
64 drivers.  Well so far I have tried 4 different parallel cards and none of 
them work. 
They might work with printers - I don't know but they definitely do not work 
with the BCD output that DDUtil provides in Win 7 - 64.  However if I boot up 
in Win XP
so that the XP driver load the card's work fine.  So I know it's the driver 
provided with the parallel cards.  I have notified the manufacture of the 
problem but they don't 
seem to care.  So consider what hardware you will be using also.  So now for 
everything except for ham radio I use Win 7 - 64, but I need to reboot to use 
the radio.

Re: [Flexradio] Questions about antennas and spectral displays...

Spectrum analyzers display signals in the frequency domain.  There are 2

Traditional swept-frequency spectrum analyzers take a brute-force hardware
approach to doing the conversion from time domain to frequency domain.  They
"tune" a detector across a specified frequency range, time-sample the

Re: [Flexradio] Questions about antennas and spectral displays...

[Mike Valentine]

I speculate that the differences between spectral display methods are due to 
design convenience and the parts cost of making it happen in each case.

Swept spectrum analyzer add-ons require the same sort of building bits 
(transistor oscillators, mixers, cheap ceramic filters, etc.) from which the 
rest of the radio is already built.  Just s few more of the same sorts of 
design concepts get you there.  Arranging the DSP filtering and selectivity 
processors of the final IF to also include a large-bandwidth FFT may be too 
much extra high-cost stuff to be competitive with a simpler analog method of 
implementation. 

The Flex also uses just a few more of its same building blocks (software 
routines) to process the already-digitized spectrum to produce an FFT.  If the 
processing power of the connected computer is great enough, no extra pieces of 
hardware are required to generate the extra feature.  Once an SDR has bitten 
off the cost of a whole PC to process signals, why pay for a completely 
separate analog chain of mixers, swept LOs and log-amp IFs to derive a feature 
that's only an extra software routine away?

Also, as a side question... Anyone happen to know why all the other

[Flexradio] WTB: QRP SDR-1000 or 1500

[Lowell White]

Hi All,

I am seeking a used SDR-1000 QRP or maybe a 1500 if someone is upgrading to
other models.

This would be for secondary / transverter use, hence the QRP.

Early versions or more recent... either OK. 

Please reply off-list with pricing, any particulars. 

Thanks,

Re: [Flexradio] SSB Audio Issues

[Tim Ellison]

In regards to George's excellent suggestions, if you are using outboard audio 
hardware which will have a mic preamp somewhere in the audio chain, you should 
not connect it to the front panel 8-pin Foster connector, but use the balanced 
line in on the back.  The front panel mic connector has a mic preamp and when 
you drive that input with a pre-amplified signal, it is easy to over drive the 
input and mismatch the impedance.  With outboard audio hardware, you want most 
of the gain in the audio chain to come from first amplifier stage, peaking at 0 
dB.  If you have low input gain and you over compensate with a lot gain in 
PowerSDR, then you will not have as good of a SNR.

For FLEX-3000 and FLEX-1500, I recommend using the audio inputs on the FlexWire 
connector since they do not have balanced line in connectors.

I have not used a Yaesu mic, but in my experience if you are getting echo there 
is too much mic drive in the line.  You didn't say if you were using any type

Another issue I have not experienced but has been on the reflector a number of

Re: [Flexradio] SSB Audio Issues

[George Steube]

Rick,
I have not used a Yaesu mic, but in my experience if you are getting echo
there is too much mic drive in the line.  You didn't say if you were using
any type of preamp or processing and that is were the problem comes in.
Another issue I have not experienced but has been on the reflector a number
of times is the proper connection of the mic +/_ lines and the ground.  Make
sure the mic is connected per the manual.

Re: [Flexradio] SSB Audio Issues

[Tim Ellison]

Check the mic cabling.

The cable shield needs to connect to the shield and pin 5 of the  8-pin foster 
connector.

The mic (-) wire needs to be on pin 7 of the 8-pin foster connector and NOT 
connected to the mic cable shield or pin 5.

Obviously the mic (+) needs to be on pin 8 and PTT on pin 6.

Here is what I did.  In researching the issue, I checked the earlier hot fix 
for SP2 on the same issue:

http://support.microsoft.com/kb/885222

It requires you to go into the registry and add in the SidSpeed parameter.
Since it was missing from both my cards, after the usual registry backup, I 
experimented with entering it.  The first card went perfectly, and showed up in 
the Flex diagnostic as S400.  However, the second card kept giving me an error 
message when I tried to enter a new value.  After some head scratching, I 
checked the permissions for the two branches.  Sure enough, they were 
different.  I reset the permissions for that branch, entered the SidSpeed 
parameter, and then ran the KB955408 hot fix.  Worked perfectly.  I was choking 
on the more restrictive permission.

I don't know why the permissions were different.  One port is on the board, and 
the other a PCI card which I installed recently.  Things seem to be working 
now, though I will not know for certain until I get the rig.  ;)

[Flexradio] Which OS for i7 new PC?

[sgholly]

Greetings,

I'm thinking about building an i7 powered computer for my radio shack. I'm very 
comfortable with XP but given XP's age and eventual end-of-life status perhaps 
one of the Win7 versions would be more appropriate. I tend to keep my PC's for 
a long time so I'm looking for an OS that will serve me for at least 5 years of 
so. 

Thank you,
Steven, WI2W

Do this. 

Do you get this error...
http://kc.flexradio.com/KnowledgebaseArticle50440.aspx

When you check the compatibility of your Firewire chipset?
http://kc.flexradio.com/KnowledgebaseArticle50456.aspx

If so, then your Firewire is running at 100 MB rather than 400 MB and this
can result in audio distortion and drop outs.

If not, then don't worry about the hotfix.

Justin,

I am very new at this, but my understanding is that the latest SDR installs
checks whether it is needed.  2.0.16 popped up a message saying I should
install the patch.  Since I posted, I have been able to grab the contents of
the upgrade directory before Windows can delete it.  Running the UPDATE.EXE
file gives a message saying "The file is not correct."  ??  Don't you just

Hi Alan,

Ah, OK then.

Do you *need* the patch? Does your system work without it? I had an issue
with installing it too. I finally gave up and tried without it, there have
been no issues.

Is it possible you are trying to install on a disk other than the C drive? I
have seen this error when there was a problem to install programs on any
location other than the C drive/

[Flexradio] Questions about antennas and spectral displays...

[George Works]

In all this discussion about matching, just remember that there are two 
issues with antennas.

 1. You have to get the power into the antenna by matching
 2. The antenna has to radiate the power in a direction that will reach 
the intended receiver.


You can learn a lot about your antenna by modeling it. If it is a 
vertical longer than 1/4 wave, or twice that for a dipole, it will have 
lobes and nulls. It may be sending most of your power in directions 
where nobody will receive it. I recommend EZNEC as a cheap, easy and fun 
way to discover where your power is really going. If you can set up a 
Flex, you can certainly use EZNEC.


George, PJ5/KJ6VW
