Bradley,

 

On the fourth floor, even a connection to earth ground would not be a ground
because of the impedance of the ground conductor at RF.  This could
certainly be one of your issues.

 

With regard to the front panel microphone connection.  Be sure shield is
connected to the connector housing so that it is connected directly to the
chassis.   You might want to read about the "Pin-1 Problem" in XLR circuits.

 

http://www.rane.com/note165.html

 

You may also want to run the PR-781 balanced into the back of the radio.  A
balanced input can be a big help with RFI.  

 

Good luck,

Gerald

To answer your question, the reason both temporary antennas are 30M antennas
so I can tune them for 6-40m and run low power SSB.

The MMD antenna is supposed to have a Current-Mode Discriminator which,
among other things, is supposed to prevent RF running back down the
feedline.   The dipole is a textbook dipole fed with coax.

If I transmit into a dummy load (a giant 50ohm resistor I bought at a ham

feedback, no distortion.  Audio sounds fine in another receiver.

Also, I don't have a traditional RF ground yet and the radio is on the 4th

tried yet at this QTH.   As I've said, I'm setting up this QTH new, so I'm

one in the grounding article in the Flex Knowledge center).

Hi Bradley,

I've been following your adventures this morning with your new Flex.
Everything you have said so far points to RF getting back into the
radio/computer/speakers. Your first post seemed to indicate you had transmit
audio feedback from either radio speakers that were reproducing transmit
audio because the Monitor button was activated in PSDR, or you had a second
receiver in the shack to listen to your transmit audio. If you want to
listen to your transmit audio, you MUST prevent the audio from getting back
into the microphone and creating a big feedback loop.

Since the first post, your symptoms now sound like a classic case of RF
feedback (different from audio feedback). You speak of a 30M antenna, first
an end fed model and then a dipole fed with coax. I'm a little confused
here. 30 meters does not permit SSB operation; only CW or digital. Am I
understanding you correctly? Also, a dipole is inherently a balanced
antenna, which you are feeding with coax, an unbalanced feed line. Very
common practice I grant you, but one that is also very prone to bringing RF
back into the shack. Do you have a dummy load? That would be a much better
test if you have one. Hook up the dummy load in place of the antenna, and
try things again. Remember to use headphones to listen to your transmit
audio so you don't have audio feedback, and check things out at several
different drive (output power) levels. Watch your mike levels as you
transmit, adjusting mike gain so the mike indication on the meter does not
go over 0 dB, even on voice peaks.

HF RF can cause the same type of sounds from powered speakers that VHF FM
can, so I don't think you are having an issue with the V/U modules being
keyed by mistake.

I also have a 5000 with all the goodies, and totally love it. I hope some of
these suggestions will help you get the issues worked out successfully. Let
me know please of any of thes

Hi Pierce

Ignore the nattering chatter from the peanut gallery. This one is really
silly (not your problem but the cause)!

Microsoft security geniuses have determined (months of in-field study and
laboratory experiements) that viruses are most likely to be introduced from
downloaded programs named Setup.exe! Its amazing but true!

Try renaming Setup.exe to VSPSetup.exe and run it and see if it fixes the
security constraints.

Re: [Flexradio] New 5000A User - TX Audio (severe distortion) Issues

[Bradley Feldman]

Brett:

On the Heil Cable, the Mic negative and shield are tied together at the XLR
End with the Mic Negative running on the shield to Flex pin 7.  So on the
XLR, only pins 1+2 are used.  Pin 3 is not connected.

Seems wrong to me.   What's the definitive answer on how it should be?   The
cable appears to be 4 conductor + shield.   What should go where?  If anyone
has a final answer, I'll unsolder both ends and rewire it properly.

Thanks in advance,

Bradley, 
I really don't think the Shield is supposed to be connected to pin 7 that is
the MIC's (-) side NOT GROUND. The shield according to the manual is
connected to pin 5 so Pin 5 and the shell should be connected together as
the Chassis Ground. 

 Again Page 5 of the FLEX 5K's owners manual show the proper connections for
the FLEX-5000 MIC connector, I quote "Pin 5 is Chassis Ground, Pin 6 is PTT,
Pin
7 MIC (-) Pin 8 MIC (+)".

Re: [Flexradio] crackling noise

[Tim Ellison]

" If the intermittent crackles co-inside with DPC spikes, then you need to 
figure out what is causing that.  Likely some other peripheral that is tying up 
your kernel."

If it is a DPC problem, the culprit(s) will be

Bluetooth transceiver
Wireless transceiver
NIC card
Video card.
USB

Excessive and/or long duration DPCs are hardware/driver problems.  Upgrade your 
hardware drivers to the latest version especially if you are using Win7.  Also 
you need to make sure your BIOS is at the latest revision too.

Here is the other thing to check.  If your FLEX-1500 is connected to a USB 
controller that is connected to a low speed polling device like a keyboard 
and/or mouse (wired or wireless), it will adversely affect the performance of 
the FLEX-1500.  If you are using a laptop, there could be oodles of things on 
the USB controller.  Here is how you check to make sure the FLEX-1500 isn't

In addition to looking at the CPU loading in Task Manager, I also suggest that
you download the tool named DPC Latency Checker   from

and run it.

The intermittent crackles caused by the CPU loading can usually be cured by 
installing the ".dll" patch for 2.0.1.

If the intermittent crackles co-inside with DPC spikes, then you need to figure 
out what is causing that.  Likely some other peripheral that is tying up your

I would look at these things before buying a new computer.  [Unless you are

Re: [Flexradio] crackling noise

[Graham Haddock]

Peter:
In addition to looking at the CPU loading in Task Manager, I also suggest
that
you download the tool named DPC Latency Checker   from

http://www.thesycon.de/dpclat

and run it.

The intermittent crackles caused by the CPU loading can usually be cured by
installing the ".dll" patch for 2.0.1.

If the intermittent crackles co-inside with DPC spikes, then you need to
figure
out what is causing that.  Likely some other peripheral that is tying up
your
kernel.

I would look at these things before buying a new computer.  [Unless you are
looking for an excuse for Santa to bring you an upgrade.]

Make sure you power cycle the radio.  Upgrading to 2.0 loads a new firmware 
version and the soft reset may not have properly rebooted the radio.

Re: [Flexradio] File management

[pierce day]

My apologies to all.  The warning to not download the VSP files to C:\Programs 
Files\  directory came not from the Flex wiki, but from a printout I made some 
time ago from Steve's K5FR instructions.  Furthermore, the instructions were 
not specific in regards to a Vista, Win 7, or other program.  

OK, so the wiki printouts I keep in the same folder with K5FR's printouts are 
for FLdigi and HRD.  And I do know the difference, but sometimes I don't act 
like it.

Bradley,

 

On the fourth floor, even a connection to earth ground would not be a ground
because of the impedance of the ground conductor at RF.  This could
certainly be one of your issues.

 

With regard to the front panel microphone connection.  Be sure shield is
connected to the connector housing so that it is connected directly to the
chassis.   You might want to read about the "Pin-1 Problem" in XLR circuits.

 

http://www.rane.com/note165.html

 

You may also want to run the PR-781 balanced into the back of the radio.  A
balanced input can be a big help with RFI.  

 

Good luck,

To answer your question, the reason both temporary antennas are 30M antennas
so I can tune them for 6-40m and run low power SSB.

The MMD antenna is supposed to have a Current-Mode Discriminator which,
among other things, is supposed to prevent RF running back down the
feedline.   The dipole is a textbook dipole fed with coax.

If I transmit into a dummy load (a giant 50ohm resistor I bought at a ham

Also, I don't have a traditional RF ground yet and the radio is on the 4th

Hi Bradley,

I've been following your adventures this morning with your new Flex.
Everything you have said so far points to RF getting back into the
radio/computer/speakers. Your first post seemed to indicate you had transmit
audio feedback from either radio speakers that were reproducing transmit
audio because the Monitor button was activated in PSDR, or you had a second
receiver in the shack to listen to your transmit audio. If you want to
listen to your transmit audio, you MUST prevent the audio from getting back
into the microphone and creating a big feedback loop.

Since the first post, your symptoms now sound like a classic case of RF
feedback (different from audio feedback). You speak of a 30M antenna, first
an end fed model and then a dipole fed with coax. I'm a little confused
here. 30 meters does not permit SSB operation; only CW or digital. Am I
understanding you correctly? Also, a dipole is inherently a balanced
antenna, which you are feeding with coax, an unbalanced feed line. Very
common practice I grant you, but one that is also very prone to bringing RF
back into the shack. Do you have a dummy load? That would be a much better
test if you have one. Hook up the dummy load in place of the antenna, and
try things again. Remember to use headphones to listen to your transmit
audio so you don't have audio feedback, and check things out at several
different drive (output power) levels. Watch your mike levels as you
transmit, adjusting mike gain so the mike indication on the meter does not
go over 0 dB, even on voice peaks.

HF RF can cause the same type of sounds from powered speakers that VHF FM
can, so I don't think you are having an issue with the V/U modules being
keyed by mistake.

I also have a 5000 with all the goodies, and totally love it. I hope some of
these suggestions will help you get the issues w

[Flexradio] crackling noise

[Peter - VE3HG]

Thanks to those who suggested the graphics card might be the suspect. Sure 
enough swapped Windows 7 computers and no crackling.

The 2.80 gig HP with a GeForce 8600 GT card and 4 gigs of memory was the 
problem. A 3.33 gig E-Machine with a lesser ATI HD4350 card and only 2 gigs of 
memory ran quiet - no crackling.

However the 2 gigs RAM in the E-Machine don't seem sufficient for clean CW. 
I'll try more RAM but it's looking more and more like a new computer :(

Re: [Flexradio] crackling noise

Peter,

Bring up the Performance tab on the Windows Task Manager and see if you are
getting 100% CPU spikes that look like a heartbeat.  If so you may need to
implement Step 5 in the FLEX-1500 Driver Patch Kit for PowerSDR v2.0.16
Installation & Troubleshooting Guide on the download page.  It may be that
your computer can't handle the 1ms buffer transfer rate of the stock driver.
 The other users suggestions posted earlier are valid as well.

Re: [Flexradio] New 5000A User - TX Audio (severe distortion) Issues

[George Works]

Bradley,
If you can run full power into a dummy load but not into an antenna, you 
almost certainly have RF pickup problems.


I had problems like this with my Flex-3000. For me, the worst problem 
was the Firewire cable since I run mostly digital modes and not voice. 
What I did was run a good grounding system in the shack with everything 
tied to a wide copper strap that runs around the room, including the 
computer. My coaxes pass through lightning protectors in an aluminum 
plate, also tied to the strap. The strap is also tied to a good ground 
rod outside, but this is less important than getting every chassis in 
the shack at the same potential. Then, I put clamp-on ferrites on both 
ends of every cable connected to the Flex, computer, tuner, other 
radios, etc. Now I don't have any RF problems at all.


I did this a little at a time over a couple of weeks. The more things I 
grounded, the better everything worked. The same with the ferrites. And 
don't forget the wires to wall-wart power supplies.


Best of luck, if you keep at it you will cure the problem.

To answer your question, the reason both temporary antennas are 30M antennas
so I can tune them for 6-40m and run low power SSB.

The MMD antenna is supposed to have a Current-Mode Discriminator which,
among other things, is supposed to prevent RF running back down the
feedline.   The dipole is a textbook dipole fed with coax.

If I transmit into a dummy load (a giant 50ohm resistor I bought at a ham

feedback, no distortion.  Audio sounds fine in another receiver.

one in the grounding article in the Flex Knowledge center).

Hi Bradley,

I've been following your adventures this morning with your new Flex.
Everything you have said so far points to RF getting back into the
radio/computer/speakers. Your first post seemed to indicate you had transmit
audio feedback from either radio speakers that were reproducing transmit
audio because the Monitor button was activated in PSDR, or you had a second
receiver in the shack to listen to your transmit audio. If you want to
listen to your transmit audio, you MUST prevent the audio from getting back
into the microphone and creating a big feedback loop.

Since the first post, your symptoms now sound like a classic case of RF
feedback (different from audio feedback). You speak of a 30M antenna, first
an end fed model and then a dipole fed with coax. I'm a little confused
here. 30 meters does not permit SSB operation; only CW or digital. Am I
understanding you correctly? Also, a dipole is inherently a balanced
antenna, which you are feeding with coax, an unbalanced feed line. Very
common practice I grant you, but one that is also very prone to bringing RF
back into the shack. Do you have a dummy load? That would be a much better
test if you have one. Hook up the dummy load in place of the antenna, and
try things again. Remember to use headphones to listen to your transmit
audio so you don't have audio feedback, and check things out at several
different drive (output power) levels. Watch your mike levels as you
transmit, adjusting mike gain so the mike indication on the meter does not
go over 0 dB, even on voice peaks.

HF RF can cause the same type of sounds from powered speakers that VHF FM
can, so I don't think you are having an issue with the V/U modules being
keyed by mistake.

I also have a 5000 with all the goodies, and totally love it. I hope some of
these suggestions will help you get the issues worked out successfully. Let
me know please of any of these ideas work for you.

Re: [Flexradio] New 5000A User - TX Audio (severe distortion) Issues

[Gerald Youngblood]

Bradley,

On the fourth floor, even a connection to earth ground would not be a ground
because of the impedance of the ground conductor at RF.  This could
certainly be one of your issues.

With regard to the front panel microphone connection.  Be sure shield is
connected to the connector housing so that it is connected directly to the
chassis.   You might want to read about the "Pin-1 Problem" in XLR circuits.

http://www.rane.com/note165.html

You may also want to run the PR-781
balanced into the back of the radio.  A balanced input can be a big help
with RFI.

Good luck,
Gerald

Since you've done so much troubleshooting and yet still have the problem, 
you may not wish to make assumptions about the Heil cable...yeah, it's 
probably OK, but you never know til you either Ohm it out or build a test 
cable. Or try a different mic + cable.


Also are you using the rear panel balanced mic input? This bypasses the 
audio preamp which is in-circuit on the front panel jack...might give you 
improved results.

I just tried stringing up a 30 dipole, new coax, etc instead of using the
miracle MMD (which is an end fed antenna).   Same problem, so it's not the
antenna.

The mic cable is the stock cable from Heil, so I assume it's good and 
proper

cable.

Any other ideas from anybody?

You may want to try lifting the chassis ground off the XLR ground. Also
remember XLR audio is balanced so you don't want either of the XLR mic 
pins

grounded or tied to the shield or chassis.

Sometimes NO ground at all on an XLR connector worksyou get these 
ground

loops and current floating around which makes the audio connection
UNbalanced, and greats hum, RF paths, etc.

Another thing...take a look at the innards of your mic cable. If it's an
XLR, you should have twisted pair for the two mic leads, which may or may
not be wrapped in a shield. For XLR, think of your audio line much as you
would think of a balanced antenna & feedline.

The PTT is connected properly to pins 5+6.  Mic positive (XLR pin 2) is

Check the HEIL MIC adapter and MAKE sure that the MIC ground goes to the
radio MIC Ground and the PTT Ground goes to PTT Ground on the radio.
On a LOT of the HEIL adapters they wired the ground pins backwards and
this
may be the cause of your problems, on Yaesu radios this didn't make much
difference but on the FLEX it makes ALL the difference in the world.

The 1500 has a crackling noise which is occurring randomly every second to 
every few seconds or so. Sounds just like a broken speaker cable. Not so 
noticeable on SSB but on CW it's unacceptable.


Changed the headphones; used a dummy load; tried different bands and the 
only thing that killed the noise was turning off the panoramic display. 
Noise reappears when display is on.


Made working the 160 CW contest a royal pain in the ears which was 
disappointing as the receiver filters were way beyond anything I've ever

The PTT is connected properly to pins 5+6.  Mic positive (XLR pin 2) is
connected to flex pin 8.   Mic negative (XLR  pin 3) and Mic Shield (XLR pin
1) are tied together at the flex side and go to flex pin 7.   The barrel on
the flex side isn't connected to anything.

Does that sound correct?

Check the HEIL MIC adapter and MAKE sure that the MIC ground goes to the
radio MIC Ground and the PTT Ground goes to PTT Ground on the radio.
On a LOT of the HEIL adapters they wired the ground pins backwards and this
may be the cause of your problems, on Yaesu radios this didn't make much

I'm new to flex, sdr and this list.

I have a brand new 5000A, fully loaded (including the VHF/UHF board).
Station is completely new -- new QTH, new Mic (PR 781), new temporary
antenna (Miracle MMD 30m).

I've worked through issues on installation and receive and seem to have
those licked including using VAC with digital modes.   Now I'm trying to get
TX working right for working QRP until spring comes and I can set up my
Steppir Bigir that's sitting here in a box.

I've been a ham since 1990, but have largely been on my own with regard to
setting up and solving shack problems-- I don't belong to any clubs at the
moment, so I appreciate any help I can get from this list with the issue I
describe below -- which may not be a "flex issue" but perhaps an ordinary
ham setup issue.  I don't know.

Here's the issue:  When keying up and testing my mic in phone mode (I don't
have a key set up), once there is enough audio level to drive some rf output

One more thing.   I do also hear buzzing out of the amplified speaker for
the radio (separate AC sound amp with ground loop isolator, shielded cables)
and through the computer's speakers (also ground loop isolated).

In the past I've heard this type of buzzing with FM transmit, but never ever
with HF transmit.   Could the VHF/UHF board be keying up with the HF?

Yep it sounds like it is wired correctly, It must be RF getting into the
Radio some how, Have you tried transmitting into a dummy load to see if
there is still distortion??

RF gets into the MIC TX circuit quite easily if you are in the "near field"
of your Antenna system and you may need to add some snap on MIX 31 ferrite
beads as I have done here that were required when I run my AMP to full power
in my situation, these are just like the ones on the Fire wire cable. 

Just a few suggestions that I have ran into in my 2.5 years of running 2
FLEX 5K's and a Flex 3K here. 

Hope this helps

I just tried stringing up a 30 dipole, new coax, etc instead of using the

The mic cable is the stock cable from Heil, so I assume it's good and proper

You may want to try lifting the chassis ground off the XLR ground. Also
remember XLR audio is balanced so you don't want either of the XLR mic pins
grounded or tied to the shield or chassis.

Sometimes NO ground at all on an XLR connector worksyou get these ground
loops and current floating around which makes the audio connection
UNbalanced, and greats hum, RF paths, etc.

Another thing...take a look at the innards of your mic cable. If it's an
XLR, you should have twisted pair for the two mic leads, which may or may
not be wrapped in a shield. For XLR, think of your audio line much as you
would think of a balanced antenna & feedline.

Re: [Flexradio] New 5000A User - TX Audio (severe distortion) Issues

[Ross Stenberg]

Possibly what compounds the problem is the fact that the antenna is an end 
fed Hertz which is inherently unbalanced and will present RF on the shield 
back to the radio.




I have a brand new 5000A, fully loaded (including the VHF/UHF board).
Station is completely new -- new QTH, new Mic (PR 781), new temporary
antenna (Miracle MMD 30m).

Re: [Flexradio] New 5000A User - TX Audio (severe distortion) Issues

[Bradley Feldman]

The PTT is connected properly to pins 5+6.  Mic positive (XLR pin 2) is
connected to flex pin 8.   Mic negative (XLR  pin 3) and Mic Shield (XLR pin
1) are tied together at the flex side and go to flex pin 7.   The barrel on
the flex side isn't connected to anything.

Does that sound correct?

Page 5 of the FLEX 5K's owners manual show the proper connections for the

Measure from the MIC itself and make sure they have the correct one

ham setup issue.  I don't know.

Here's the issue:  When keying up and testing my mic in phone mode (I don't
have a key set up), once there is enough audio level to drive some rf output
power, I start to hear distortion in the audio-- it kind of sounds like the
sound of a helicopter with echo and reverb that continues until I unkey.

I've done Google searches, flex KB searches, forum searches and read the

That's OK. Neal wrote that part. Bad Neal! Bad, Ban Neal! :-)

I don't have Win7 and don't have any plans to install it in the near future
so any Win7-specific stuff in the Wiki has to be written by someone else.

And speaking of the Wiki, several people have come to me with instructions
they have come up with they want to share with others. (GOOD!) Even though I
have said it before it hasn't sunk in that ANYONE CAN ADD ANYTHING TO THE
WIKI. The Wiki is wide open for sharing information we want to persist. You
can write instructions or link to instructions already written. (Tim -- you
could be putting links from the Wiki to the KB, hmm? It would be another way
to help people find what they are looking for in the KB.)

Re: [Flexradio] New 5000A User - TX Audio (severe distortion) Issues

[Jeff Kelly]

I have the same problem on the 1500 with a Heil Dual Muff Traveler headset.
I also get a high pitched tone in the transmit audio.
Thanks - that is helpful info.

Subject: [Flexradio] New 5000A User - TX Audio (severe distortion) Issues

I'm new to flex, sdr and this list.

I have a brand new 5000A, fully loaded (including the VHF/UHF board).
Station is completely new -- new QTH, new Mic (PR 781), new temporary
antenna (Miracle MMD 30m).

I've worked through issues on installation and receive and seem to have
those licked including using VAC with digital modes.   Now I'm trying to get
TX working right for working QRP until spring comes and I can set up my
Steppir Bigir that's sitting here in a box.

I've been a ham since 1990, but have largely been on my own with regard to
setting up and solving shack problems-- I don't belong to any clubs at the
moment, so I appreciate any help I can get from this list with the issue I
describe below -- which may not be a "flex issue" but perhaps an ordinary
ham setup issue.  I don't know.

Here's the issue:  When keying up and testing my mic in phone mode (I don't
have a key set up), once there is enough audio level to drive some rf output
power, I start to hear distortion in the audio-- it kind of sounds like the
sound of a helicopter with echo and reverb that continues until I unkey.

I've done Google searches, flex KB searches, forum searches and read the
flex troubleshooting guide to try and find a solution.  Based on that
information, I've tried the following:   I've grounded the radio to the PC
with ground strap.  I installed RS ground loop isolators on all audio
connections to/from the radio and PC.  I put extra ferrites on the PC side
of the stock flex firewire cable.

The issue remains.  Any ideas of what to do next or what additional info is
necessary to help me?

Re: [Flexradio] New 5000A User - TX Audio (severe distortion) Issues

[Bret Mills]

 Check the HEIL MIC adapter and MAKE sure that the MIC ground goes to the
radio MIC Ground and the PTT Ground goes to PTT Ground on the radio. 
On a LOT of the HEIL adapters they wired the ground pins backwards and this
may be the cause of your problems, on Yaesu radios this didn't make much
difference but on the FLEX it makes ALL the difference in the world.
Hope this helps and 73's and Happy Holidays

You read the Wiki :-)  (Just kidding Brian)

I have a Win7 x64 machine and I loaded VSPmanager version 1.0.2.05 in the

Re: [Flexradio] Still won't work...time to quit?

[Tim Ellison]

Download the FLEX-1500 2.0.16 driver troubleshooting guide along with the 
driver patch kit.

Work through the troubleshooting steps and do all of them you can (you may not 
be able to do the BIOS change depending on your PC BIOS - step 3).

I would skip Step 4 for last as Step 5 fixes 99% of the issues reported

http://support.flex-radio.com/Downloads.aspx?id=356

http://support.flex-radio.com/Downloads.aspx?id=355

If all of these fail, do Step 6 and contact FlexRadio EU Support 
(flexradio...@t-online.de)
