You can always build your own T/R switch. They are pretty simple.

The early days (after spark gap), I used one for my DX40 and HR10B receiver.

I made a LOT of CW contacts with that pair.

Well, this thing (or it's current replacement) does cost $200 but if you don't 
have to worry about switch timing or the protection of a receiver that might 
cost much more than $500 I won't argue that this is a good suggestion.   I 
bought one to use with an SDR-IQ or Flex1500 and one of my older backup 
transceivers.

Re: [Flexradio] Radio Control

[Army Curtis]

Bill,

Something that may help you with setting the drive level (and the other sliders 
as well), rather than trying to "grab" the slider "knob" and move it to the 
desired level, put your mouse cursor in the slider "track" next to the "knob", 
not on the "knob" and click the mouse. Each click will move the slider by 1. 
For example, if your tune level is set to 50, clicking in the "track" above the 
"knob" will increase the tune level to 51. Click again and it becomes 52. Much 
finer control without having to move the mouse. This can work especially well 
with a trackball.

Hope this helps.

73, Army AE5P

Re: [Flexradio] Radio Control

[Tony Estep]

Bill, controlling the Flex with the Hercules was a true stroke of genius,
and it cost only 65 bucks. The new Flexes revert to the mouse-tuning model,
but Flex has announced a very nice add-on called the Maestro that can do
what the Hercules used to do. It will be available late this year for $999.

Re: [Flexradio] Radio

With the MFJ-1025 or 1026, you need a second antenna that hears the level of 
noise as strong as, or stronger
than what you hear it on your main antenna. It is quite easy and intuitive 
using a Flex radio to see if the noise
source is being picked up equally strong. You really need to first determine 
where the noise is coming from.
If it is a neighbour, then install a low wire antenna along the boundary 
fence/wall/hedge with your neighbour,
trying different antennas or antenna orientation to maximise the noise level on 
your “noise antenna”. 
Then using the MFJ-1026 you just null out the noise on your main antenna. 
There are many youtube clips on youtube showing you how it’s done. Just search 
for MFJ-1026 on youtube

Plug it into the white TX jack next to the red remote jack.  I mainly work
cw and set the delay to 200 to keep the 811H relay from tripping inside
letters.  Without the amp the delay can be set to 0 for essentially full
breakin.

Could someone tell me where in the back of the 6300 I should put the RCA

[Flexradio] Radio viewing request

[KC8JRE]

My name is John Pick.  My call is KC8JRE.  I live in Minford,  (South
Central Ohio).  I plan to purchase a FLEX 5000 radio in the very near
future, then upgrade to the 6K series at a later date.  I was planning to go
to the Shelby Hamfest in North Carolina August 31st.  However, I thought I
would put out a request to see if anyone in the tri-state area (Ohio,
Kentucky, WVa) would be willing to show me their Flex 5000.  I am trying to
save myself a lot of driving.  Columbus or Cincinnati Ohio area, Huntington
or Charleston WVa, etc would be better for me than driving to Shelby NC.  If
anyone is willing to show me their radio in operation I would appreciate it.
I would like to see, or better yet operate the flex radio for a short period
of time before purchasing one.  My schedule is pretty much open.  I am
retired so any day is okay with me.  

 

Thank You . 73

 

John Pick

Re: [Flexradio] Radio disappeared

[George Works]

Thanks to everyone on this list for their helpful comments. The F3k 
still isn't working, but many possible problems have been ruled out. 
This radio worked for years before the problem developed.


The legacy driver is installed.
The green Firewire light inside the Flex lights when the firewire cable 
is plugged in and not otherwise.

I tried three different firewire cables with the same result.
I tried two different PCs with the same result (both using VIA chipsets 
and legacy drivers).

I tried two different versions of PSDR with the same results.

I now have a help ticket open and am working with Dudley on this.

Re: [Flexradio] Radio disappeared

[Neal Campbell]

Make sure you are using the Legacy OHCI 1394 drivers for your firewire
card. Open the Flex control panel applet and go to the DPC tab and see if
there is a recommendation on what setting you should be running the driver
in (eg, Low Latency, Normal, etc). Set the mode per its recommendation.

Shutdown the computer and move the firewire cable to a different firewire
socket on your computer. Since you are using a 3000, you only have one
firewire port on the radio (on the 5000 you can also try a different port).

Reboot and then power up the 3000 and see if it is recognized.

Re: [Flexradio] Radio disappeared

I recently saw an automatic Windows update for FTDI drivers on my W7 64
machine.
If you have Windows Update  running for auto updates, it may be worthwhile
to investigate.

On another note this recent FTDI update resolved a problem I was having with
the MicroHam Station Master.

I had what appears to be the same problem with my 5000A, I too was using the

Re: [Flexradio] Radio locks up when pressing the TUN button

[Gary Warner]

Tim,

Thanks for the quick response.

I was trying to tune through my Palstar AT2K manual tuner.   You are 
correct that it does not lock up when using the internal tuner.   I 
wonder why that particular combination of frequency and power caused it 
to lock up when just a few kilohertz away it worked fine?   I assume 
that your recommendation for power is anything less than the power that 
locks it up?

The reason higher power levels are allowed when tuning is some 
external ATUs and amps need more than 10 watts.


We also use TUNe at 100 watts into a dummy load to verify the PA 
maximum output without have to hook up a key in CW mode to do it.

Re: [Flexradio] Radio selector

[Tim Ellison]

"If I delete all the old Flex software before updating to 2.0.22, should this 
not clear it up?"

No, it will not.  Uninstalling PowerSDR only removes application binaries, 
sometimes drivers, but not databases.

You will need to manually "reset" the Radio Chooser database by deleting the 
master.xml file located in %APPDATA%\FlexRadio Systems

I always have my radio on first, yet the annoying (to me, as I have only one
Flex) chooser shows up.  I believe this started  when I updated to 2.0.19(?) 
and did not delete the old software before installing the new.  There are two 
different serial numbers showing but I've never had but one Flex on this 
computer.  I've been ignoring it as a problem with the update..

If I delete all the old Flex software before updating to 2.0.22, should this

You can try and reset the radio chooser's database by deleting the

Would this wipe out my entire setup for the radio or only the radio type?

Re: [Flexradio] Radio selector

[K9DUR]

Ignacio,

If you have more than one radio installed, I do not believe that there is.

However, if you only have one radio, the radio chooser will not be displayed
unless you start PowerSDR without having the radio powered on.  In that
case, go to your %APPDATA% directory, go to the "FlexRadio Systems" folder,
and delete the master.xml file.

In XP, the %APPDATA% directory is located at 

   C:\Documents and settings\\Application Data

In Vista & Win7, it is at

   C:\Users\\AppData\Roaming

In either case, "" is your user name on the PC.

Hi Neal

Everything you had suggested in your reply had already been done except 
checking DEVICE MANAGER which had recognized the Firewire port and had the MS 
legacy driver operative.

I cycled the power to the radio and, Viola', the radio started got the 
calibration data and started right up so I could hear the powerline noise 
easily (and a few QSO's). Why would this happen? When I shut down, I always 
stop PowerSDR, wait a few seconds for any file writing and closing, then shut 
down the radio, and only then do I clcik on "shut down" which is a function of 
the OS. Is my sequence in error? It appears that the calibration data 
disappeared - but he radio immediately appeared, and transferred the 
calibration data, after I did the power cycling while the PC was on.

Usually I boot the PC, which is lightning fast with the SSD from Abroham Neal, 
wait 60 seconds and let NOD32 do its thing and all other devices install, then 
I power up the radio and wait about 75 seconds before starting PowerSDR. Is 
this sequence incorrect?

Re: [Flexradio] "Radio Not found" Error Message

[Neal Campbell]

Hi Brad

First, go to the Control Panel->Device Manager and see if the firewire card
is being recognized properly. Make sure you have the legacy driver loaded.
If thats okay, then close that out.

Next, open the FlexDriver. Does the driver see your radio? If not, make sure
its plugged firmly into the firewire socket on both the radio and the
computer.

Until you see a radio in the FlexDriver, you will not see one in PowerSDR.
If you do not, cycle power in the radio and see if one appears. If not, try
rebooting your computer, and power it back on with the radio turned off.
Once Windows has fully come up, then power on the radio.

S9+30 = about -47dBm?
Typical XOs put out around +10 dBm, so a 60 dB pad will get it to the  
right level, and has the advantage of providing 120dB isolation  
between oscillators.

For this experiment, one wouldn't need fancy OCXOs, either. Just very  
clean oscillators. You might be able to get by with low jitter DIP  
packaged oscillators (like the one in the SDR1000), and just get a  
bunch of them, hoping they're spread out enough.

Your suggested tests are very much like the noise power notch test,  
which has been around for decades (first used in carrier telephony, I  
believe).  You put a wideband noise signal into the device under test.  
  Then, you notch out a subband (typically a 3 kHz wide "voice  
channel").  You measure the two different powers going into the UUT  
(unnotched and notched).  Then, you measure the two different powers  
coming out of the UUT.  If the device is linear, then the ratios  
unnotched to notched should be the same.  If there is IMD, then the  
notched power coming out is too high (i.e. spectral regrowth has  
filled in the notch)

You can also do it by making a narrow band measurement in the notch.

W6RMK:

When that person steps forward, the following would be an interesting
receiver test (simulates a contest like the CQ 160 CW):
Space S9+30 carriers every 500 Hz and measure the change in noise
floor while cycling them on and off.  Next step would be to key the
signals on and off (unsynchronized).

An equivalent test for SSB would use spacing every 2 kHz, but adding
modulation to simulate an SSB signal.

The tests we have (IMD, BDR, Phase Noise...all using very pure
continuous sources) are woefully inadequate to simulate the real world
of transmitted phase noise, key clicks, SSB IMD splatter, etc.  Rather
than just 2 pure tones for IMD tests, it would be interesting to see
the combined effect of many.  Seems like you would get an additive
effect from phase noise over a very wide bandwidth.

Interesting.  100Hz at 10MHz is 10 ppm, which is probably within the  
range of the electronic tuning input on OCXOs (barely)

But no way are you going to push it several kHz (at least not if it's  
a really good crystal).

Maybe a classic divide and mix synthesizer?

But maybe it's not worth it for digital radios.. (i.e. rather than  
spending one's time trying to build the ideal test set for a  
particular measurement, look for other measurements that may be of  
equal or better value)

And that's not the only problem with the E8663B.. when you step  
frequencies, it's not phase continuous.  (Although, I think that's  
actually a bug)

[Flexradio] Radio Test Issues

[Rob Sherwood]

Comments on testing radios.

Why not test at really close spacing?
The real limit will usually be phase noise at 1 kHz or closer.
I may have made an error on an earlier post.
The IMD DR3 of the K3 with the 500 Hz 5-pole roofing filter and 500 Hz DSP 
filter was a combination of phase noise and IMD.  2 dB of the peak was noise, 
and 1 dB of IMD for the 3 dB peak.
The K3 DR3 of 101 dB was completely noise limited with a 200 Hz roofing filter 
and a 200 Hz DSP bandwidth.
At 1 kHz the phase noise is 6 dB worse than at 2 kHz.  
While I have not measured it, it will likely go up another 6 dB at 500 Hz, so 
you are really running into noise at that point.
That being said, during the ARRL DX CW contest this weekend, the really strong 
signals, S9 + 40, often had key clicks that were the practical limit. 
I would not call a roofing filter a crutch.  It fixed the R-4C 33 years ago, 
and the concept still works.  
The Flex 5000A and the K3 are both exciting products, with completely different 
approaches to high-performance reception. 

One can test radios with really clean OCXOs, but that does not give much 
flexibility.  One needs to be able to move around to deal with real-world 
spurs.  Sometimes it is necessary to make a 20 kHz test at 19 kHz or may be 21 
kHz because a weak spur ends up right on the frequency where you are looking 
for IMD.   Also it is really important to be able to "wobble" both signal 
generators to be sure one is really looking at the 3rd order product.   I 
"wobble" both generators +/- 100 Hz and listen for the intermod product to 
"wobble".  Otherwise you can fool yourself.

My generators are two 8662As and one 8642A.  My 8663A needs a part and is on 
the shelf.  The E8663B is a current Agilent product, but besides being too 
expensive, is not as clean at HF frequencies as the older generators.  Agilent 
even have a paper on using external, low-noise frequency dividers to improve 
the E8663B phase noise performance below 250 MHZ. 
http://cp.literature.agilent.com/litweb/pdf/5989-5099EN.pdf 

I did test the K3 to see what it did with a 2.7 kHz roofing filter, but a 500 
Hz DSP CW bandwidth.  You can get away with doing that for casual CW operation, 
but it would not be a good way to run a contest.  

The Orion II was tested at 1 kHz with the 300 Hz roofing filter, and the result 
was the same as the 2 kHz test with a 600 Hz roofing filter: DR3 = 95 dB.  

If one had a perfect receiver, whatever that is, and you are trying to work a 1 
uV signal with a S9 + 40 over signal a few hundred Hz away, you are dead in the 
water.  The transmitted phase noise of the strong signal, plus his key clicks, 
will likely doom the effort.  What the new batch of radios from US 
manufacturers has done is gotten the close-in dynamic range performance up from 
around 70 dB to the mid 90s or above.  Now that is a big deal. 

At least you can now choose a radio that is not likely to be a practical limit 
in a CW pile up / contest.  
I don't agree that analog radios are history.  Digital is just different.

73, Rob Sherwood, NC0B

Re: [Flexradio] Radio with a computer in it vs. a computer with a radio in it

[Robert McGwier]

The panadapter shows the transmit digital stream BEFORE it hits the QSE 
(sdr exciter).  There is no way to do it any other way in the SDR-1000. 
  The Flex 5000 is considerably more versatile in this regard because of 
its dual RX/TX IF.  In fact,  the plan is to tune the transmitter 
predistortion (equalizer) by listening to it with the receiver.

I think it goes back farther than that. It has more to do
with the designer's fundamental view of how to *start*
designing a 'radio' and how it must look, work, and feel.  My
oversimplified take on it is this:

1. A big 4 radio company decides to design a new radio and
they typically start with this set of basic parameters:

a) The radio will be a box that sits on the tabletop.
b) It will have a frequency display.
c) It will have an S-meter.
d) It must have knobs and buttons for controls (PC
interfacing is secondary).
e) Etc.
f) Must meet performance specs X,Y,Z.
g) Price point.


The PC based SDR's such as the Flex series start with
something more like this:

a) PC technology is cheap, how can we use it to make it into
a radio?
b) How can we minimize the amount of radio/RF specific HW?
c) Can we equal or exceed traditional radio circuit design
performance with minimal HW and good software?
d) PC based UI's will be primary, and can we support open
ended UI designs, (many that we can't even think of
ourselves)?
e) Also can we support knobs and buttons for control?
f) Etc.
g) Price point.

Notice that the PC based SDR product design approach is more
of a series of 'open ended' questions vs. the more
traditional 'predefined' notion of what a radio must look,
work, and feel like?

And then through some actively encouraged end user /
experimenter involvement you now have Flex radios and the
various other 'more experimental' SDR projects that are out
there today (HPSDR, Softrocks', Winrad, Rocky, etc. etc.).

 The Flex models are in a league all of their own for factory
 ready transceivers. The traditional "big 4" models are all
 still just traditional radios with computers in them.

Probably an engineering/marketing decision.. Note also that while the 
user firmware is upgradeable, it's not open.. you'd just get a 
bitstream to load.

It also does cost a fair amount to provide a reliable upgrade 
mechanism that won't inadvertently turn your radio into a brick if 
something hiccups.  the 7800 is pretty pricey, so they can afford 
it.  It might be that the "cheap way" (for the TS2000) is patented by Kenwood..

The IC7000 has the firmware in a masked rom version of the DSP, so 
it's not like the firmware is sitting in some nice memory chip where 
you can add in a programming interface.  You might be able to cobble 
something up with the JTAG interface on the DSP chip(s), especially 
if you swapped the actual chip for one with internal RAM/EEPROM, but 
that's getting pretty hairy, and clearly out of the expectation of the FCC..

It might also be because of the internal design of the IC7000 makes 
it too vulnerable.

Closed source?  They don't publish the internal interfaces or 
software documentation, so it would be quite difficult for you to 
(legally) create something that would work. Sure you could reverse 
engineer it, but that might get into trouble with DMCA..

And ultimately, it's between the mfr and the FCC.. it's a negotiated 
process because the Part 15 rules are not all that cut and dried.

See the cut and pasted comment from Ten-Tec in 2004 below.  I note 
that they did not address the equipment authorization issue, but a 
happy toiler could probably go to the fcc website and look up their 
application, and in there somewhere will be a complete description of 
how they meet the requirement. It's there for the IC7000 (I having 
looked to see if it would ever be possible to "reflash" the dsp 
code.. nope.. mask rom)

What is not understood about this discussion is that the DSP code takes
a serious engineering effort to create and cannot be simply given away
for anyone (including companies that compete with us) to use.  We have
lots of competition both in the amateur radio and non-amateur radio
arenas; to simply give away our intellectual property would let others
use our engineering effort to their advantage.  Perhaps years from now,
when current equipment is discontinued the possibility of making it
available for use and experimentation could be discussed - but in the
short term, there is no possibility of this happening.

Leaving aside the entire discussion of what a project it would be to try
to provide tech support for people troubleshooting their own version of
our code to make their radio do something specific and/or modify the
existing radio.

We do custom engineering work all the time.  There are customized
versions of DSP radios that we sell as off-the-shelf items out in circulation
right now - and there was a significant cost incurred for engineering time
to create these items.   The eventual owners of these custom radios
paid a hefty price to use our engineering time to modify our intellectual
property to get exactly what they wanted.

Slightly different topic:
I've been following the discussion about the recent lack of Jupiter updates
with a bit of trepidation.

We've taken a lot of heat over "look how many firmware updates
there have been for this rig..." and the converse is "After three years,
there haven't been recent updates coming for this rig..." - that's hard to
win either way.  Yes, updates for the Orion will continue until some
future date.  No, we haven't done any updates for the Jupiter since
fall of '03 after three years of issuing them.  That doesn't mean we
won't do them in future, however.

  Seems to me like they are converging.  The hardware in each will have their

a common goal.

  I think the biggest feature of Flex is PowerSDR.  With Flex's investment 
and excellent contributions by knowledgeable volunteers, who has better

Re: [Flexradio] Radio with a computer in it vs. a computer with a radio in it

[k5nwa]

The main reason is most likely because that is how they want to do it.

But all these fine radios do not provide you with the information and 
source code so you could make your own modifications, a huge 
difference to many when compared to FlexRadio and their open 
development. Being open was a risky decision for Flex but it has 
allowed people on the outside to make contributions. History has 
shown that it was a good decision, not just for them but for owners 
of the SDR-1000 also.

Happiness is a toy that keeps getting better.

Could it be the difference is that they don't provide enough
information to actually write your own firmware for those radios?  I
mean if you can't write the firmware yourself, you cannot change the
way the radio behaves ( ...that is, those things determined by the
firmware).

Both the Icom IC-7800 and the Kenwood TS-2000 have user-upgradeable

How does TenTec do it with the Orion, Jupiter, Argonaut V, ...  and 
still keep their authorization?

But, theoretically anyway, this can be fixed in the SDR1000... all it

Not entirely true.. my IC7000 does a lot of the same things that 
PowerSDR does, in software..  True, it uses a different LO synthesis 
scheme (PLLs and DDSes, rather than a single DDS) and a different IF 
chain (several conversions, instead of one), but that's more to 
address the wide tuning range needed... if you put a DEMI converter 
on the front of a SDR1000 to get 2m, you've built yourself a double 
conversion receiver.  Strip out the VHF,UHF, Wideband FM, and TV 
functions of the IC7000 and you'd have an architecture that's quite 
similar to the SDR1000.

But, in terms of UI management method(software in both IC7000 and 
PowerSDR) and baseband signal processing (DSP in both IC7000 and 
PowerSDR, both of an "IF" that's in the 10-20 kHz range) they're the 
same. Neither radio is an instance of the "computer turning the knobs 
of a conventional analog rig" model (e.g. my old FT757)

Probably the single biggest difference between the two is that you 
can't change the software in the IC7000, because it's got equipment 
authorization and the FCC won't allow it to be changeable to keep that auth.

This issue will be completely eliminated soon for both SDR-1000 and Flex

Re: [Flexradio] Radio with a computer in it vs. a computer with aradio in it

[Jeff Anderson]

We shouldn't forget that the flex *does* have an image (at 22 KHz), and that
there can be image rejection issues if the signal at the image frequency is
strong.  I've seen images from strong stations on the Flex panadapter
display (and might have even heard one, a long time ago).  In a contest
environment, with strong stations nearby, this problem could be exacerbated.

Nulling the software image-rejection helps at the frequency you're listening
to, but image rejection worsens (on the spectrum display) as you shift the
frequency of the image signal.

This fundamental conceptual difference is indeed lost by many
out there in ham radio land. Those who try to frame Flex
radio's competition as being in the same league as the Flex
is in terms of computer integration simply haven't grasp this
key differential concept.

The Flex models are in a league all of their own for factory
ready transceivers. The traditional "big 4" models are all
still just traditional radios with computers in them.

This fundamental conceptual difference is indeed lost by many
out there in ham radio land. Those who try to frame Flex
radio's competition as being in the same league as the Flex
is in terms of computer integration simply haven't grasp this

The Flex models are in a league all of their own for factory

Re: [Flexradio] Radio has arrived - strange operation

[Jeff Anderson]

Hi Willi (& others who've replied) - 
 
Yes, I indeed hear relays clicking whenever I change the preamp settings.  Sometimes, though, I think it might be the wrong relay that I hear (sometimes there seems to be a louder click than usual)!
 
The problem doesn't go away after a few minutes, but will randomly occur (when changing preamp settings, for example) during the course of operation.

Something similar happened to me only when using the parallel cable.  Sometimes when turning on the radio from standby my audio level would be very low as if not connected to anything.  I would have to click some band button 1 or 2 times before I would get anything.  After returning to the parallel/USB adapter it has NOT happened at all.

Hi Eric,
 
I just got home from work and ran some additional tests...
 
The radio continues to drop into "very low level" receive mode even at half-an-hour following power-up. Some things that can "randomly" cause it to drop into low-level mode:
 
1.  Changing the preamp gain (med to hight, low to med, hi to med...etc.).  This is my most consistent method of causing the failure.
2.  Clicking MOX on/off).
3.  Changing bands (60 meters to 40 meters, for example).
 
Changing bands (or clicking MOX on/off) can also cause the low-level to correct itself to the normal receive level.
 
It can occur on different bands (80, 60, and 40 meters were the bands I checked).
 
Clicking the ON/Standby button twice (or any number of times) seems to have no effect.
 
My suspicion is that a band relay is incorrectly opening, due to...a yet-to-be-determined cause.
 
The Computer is still virgin - I don't even have it connected to the internet, yet.   And the only programs on it are those that were installed at FlexRadio.  Nothing is attached to the parallel port except for the radio.

Jeff,
 
As I recall your radio had a Dell configured with it.  We have seen the issue you described after a fresh reboot.  It seems to happen a few times and then it stops even on my production machine here.  We are not sure what causes this, but it seems like some kind of a startup situation here.  If you are seeing it past that, then it would make me wonder about other possible software interactions with the parallel port.
 
What other software have you loaded on the machine since it arrived?  Anything that would be polling the parallel port?  This can cause problems with our hardware as polling certain pins could prompt the radio to think it is receiving control data (thus flipping relays).  This would typically result in the receiver dropping out without any interaction from the user (seemingly random).
 
More info may be needed to figure out exactly what is happening.  Does it always happen on the same band?  Does going to another band always clear it up?  Does clicking the On/Standby button twice clear it up?  You can use the schematics on the private download page to trace the filter switches on the RFE, and the BPF boards.

I reported this when preview 2 was released.  It does not happen in preview 1.

Symptom: After reboot when Power SDR is started, it toggles between tx and rx 
several times and then reverts to normal operation after a few seconds. The

Hi 
Eric,
 
I just 
got home from work and ran some additional tests...
 
The 
radio continues to drop into "very low level" receive mode even 
at half-an-hour following power-up. Some things 
that can "randomly" cause it to drop into low-level 
mode:
 
1.  Changing the preamp gain (med to hight, low to 
med, hi to med...etc.).  This is my most consistent method of causing the 
failure.
2.  Clicking MOX on/off).
3.  Changing bands (60 meters to 40 meters, for 
example).
 
Changing bands (or clicking MOX on/off) can also cause 
the low-level to correct itself to the normal receive level.
 
It can 
occur on different bands (80, 60, and 40 meters were the bands I 
checked).
 
Clicking the ON/Standby button twice (or any number of 
times) seems to have no effect.
 
My 
suspicion is that a band relay is incorrectly opening, due to...a 
yet-to-be-determined cause.
 
The 
Computer is still virgin - I don't even have it connected to the internet, 
yet.   And the only programs on it are those that were installed at 
FlexRadio.  Nothing is attached to the parallel port except for the 
radio.

  Jeff,
   
  As I recall your 
  radio had a Dell configured with it.  
  We have seen the issue you described after a fresh reboot.  It seems to happen a few times and 
  then it stops even on my production machine here.  We are not sure what causes this, but 
  it seems like some kind of a startup situation here.  If you are seeing it past that, then 
  it would make me wonder about other possible software interactions with the 
  parallel port.
   
  What other software 
  have you loaded on the machine since it arrived?  Anything that would 
  be polling the parallel port?  
  This can cause problems with our hardware as polling certain pins could 
  prompt the radio to think it is receiving control data (thus flipping 
  relays).  This would typically 
  result in the receiver dropping out without any interaction from the user 
  (seemingly random).
   
  More info may be 
  needed to figure out exactly what is happening.  Does it always happen on the same 
  band?  Does going to another band 
  always clear it up?  Does clicking 
  the On/Standby button twice clear it up?  
  You can use the schematics on the private download page to trace the 
  filter switches on the RFE, and the BPF boards.

FWIW in Ham Radio Deluxe I have a small window 
which monitors the parallel port, even better you could run Portmon from www.sysinternals.com which will tell you 
if anything is toggling the parallel port. Portmon will also highlight errors 
which will be of great interest to Eric.

[Flexradio] radio

[Bob W5RG]

Hi all..I'm new to this reflector and thinking about buying one..It seems hard not to really see a radio setting in front of you..I just sold two Mark Vs and still have a 781..I just heard one of these rigs on the air and it sounded pretty good..I like CW very much and think I could use this radio fine on CW..Now I'm guessing I would not need my W2IHY 8 band and EQplus with this rig but could you? Could you use the EQplus to boost the audio?
 I'll be the first to say that I'm not very up on PCs, so could a 62 year old man learn this and use it like it should be used?
 It would be nice to also have 6 meters also..I see where it could work on 2 meters..but thats not a big deal with me..Thanks Bob
