I used Skype for years on my remote base and it was great if you take 10

Re: [Flexradio] Flex has already announced an updated version of PowerSDR to be released

[Mike King - KM0T]

Snip...

Fortunately Flex has made the primary source code available, and we are
seeing developers add functions or fix minor glitches. Thank you all who
have the specialized skills to do this, and are willing to share.

Snip...

I know there are some versions of PowerSDR out there that were redone for
other hardware platforms and uses

Are you saying there are other versions for the Flex-5000 not done by Flex
Radio?   Can you point out where these versions of PowerSDR are available
for the Flex-5000?  I am not aware of these  

Thanks

[Flexradio] Flex 5K Fwd Pwr Readings ??

[Mike Rhodes]

...I probably have something set wrong but have not been able to find it 
so far.


When I transmit, even in tune, I show about 1/10 of my actual forward 
power. That is, in tune, I have 10w set in setup and that is about what 
I see on my wattmeter. However, on the PSDR 2.7.2 TX Meter, I see only 
1W. Likewise, if I set my output to 20, I will see a little over 20 
watts on the wattmeter but only about 2 watts on the TX Meter. This 
holds true for my dummy load as well as my matched transmitting antenna. 
Any idea of what I have wrong?

As we all know, living in the city presents major problems. Mine appear at 
around 4.00pm when people start getting home
from work and turning appliances on - noise levels shoot up, until after 
11.00pm.
I just watched a youtube video where an ANAN-100D was demonstrated. It shows 
the two ADC receivers in the rig being
used to phase out noise in the band….much the same way an MFJ-1026 is used to 
change the phasing of two antenna’s.
It really was quite awesome to watch how noise was reduced and most times 
removed totally from a band by changing the
phasing of the two receivers.
Can this be done with the new Flex 6000 rigs ? and is it supported in SmartSDR 
? if it can be done…any links to videos
available ? This feature would twist my arm enough to placing an order for a 
new Flex-6000 series rig

My, oh my, oh my.

You know something?  I too, might be categorized as an appliance operator and 
probably WAY too rich to be acceptable to the ascetic sensibilities expressed 
below.  My home-made bonafides include low noise microwave receivers (do a 
patent search on me) and all sorts of stuff.  Just because I don’t value my 
time so inexpensively that I’d rather buy a microphone cable than make it from 
scratch shouldn’t be a reason to shun me from the amateur radio community.  
And, I won’t let you.

You totally home brew guys that buy finished radios need to chill on the 
aspersions.

Re: [Flexradio] flex 1500 ( & 2m )

  ...however, I do not believe there are any provisions for repeater
offsets - automatic that is. You will have to dial in the offset with
the 'split' function. Have not looked at the memory functions so don't
know if you can store frequencies with offsets. Does someone else know?
  Any special reason you want to work 2 meter FM with the 1500? Are you
also interested in 2m CW/SSB because a new transverter will cost you as
much or more than a dedicated 2m FM rig and won't be nearly as convenient.

there are no shorted traces or circuits.  The spare K1 switch is also 
included.


I would like $50 for the board, which has all of the SO-239 and BNC

[Flexradio] HRFIO Board For Sale (REPAIRED )

[Mike Schwendeman]

I have a REPAIRED RFIO board for sale; I used to have two Flex-5000a 
units, now have sold both.


The "K1" switch went bad one day; I ordered and installed a replacement 
RFIO.  I asked Flex to include two replacement K1 devices.  When I 
removed the bad one, I damaged a trace.  I installed the new K1 device, 
and used a single strand from a wire, and soldered this in place of the 
damaged trace.


It is electrically CORRECT, but looks less than ideal.  I have images here:

there are no shorted traces or circuits.  The spare K1 switch is also

Re: [Flexradio] Market for 5000A's

[Mike]

I have a 5000A loaded also with the VU units and enjoy the heck out of it.
I am considering the purchase of a 6500 or 6300 when 1.4 lands and I see
what that looks like and how well it is received.  I had thought after
getting a 6xxx and after becoming familiar with it, selling the 5000A.  I do
like the idea of keeping the 5K in the shack also if there were updates to
PSDR to look forward to.  I am still intrigued by the possible expansion of
the receive capability to the VU units.  This doc pdf looks like the VU will
sample a larger slice but maybe PSDR wasn't written to analyze it?

 I think there are probably numerous valid ideas for the 5000's and 3000's
that owners could come up with to make keeping these amazing radios
worthwhile.  I for one would spend a couple hundred bucks a year to keep the
radio current.

This is the box that took my radio experience from 2D to 3D..  Conventional
knob radios now seem flat to me.   Mike W1BFA

I know I tried to sell my basic, no options, 5000A three times.? I listed it
for $1500 and had no offers.? I dropped the price to $1300, and still no
bites (this was five months ago).? I finally put it on for $1200, and the
only response was from some crank who berated me for "destroying the value
of the 5000A".? At that point, I concluded that the radio was worth more to
me than the market would pay.? It amazes me that Yaesu FT1000MP's or
FT2000's still bring between $1200-$1800 (sometimes more), rigs that are
clearly inferior to the 5000A.? I'll keep mine as long as the software
continues to work, and the hardware can be maintained.? Wouldn't mind a 6300
or a 6500 though.?K0GFY? R. Hunter Ellington

[Flexradio] PWR SDR FAILURES

[Mike]

I have recently began to experience sudden crashes of PSDR.  It began
happening with the install of ver 2.7.2.  I was using an older XP machine
and it was suggested that the OS wasn't robust enough.  I have subsequently
got a new computer running Windows 7.  I has an I7 processor and 16 GB of
ram.  Anyway, the problem persists in spite of doing a completely new
install of PSDR.  The crashes occur mostly during receiving, but
occasionally during a transmission.  The error message says something about
an unhandled exception from an external device.  I am not using any
anti-virus software and no other programs are running in the background.  I
am never connected to the internet when the crashes occur.

 

Any ideas would be appreciated.

Re: [Flexradio] Flex 5000A w/earbuds

[Mike Sonn]

I think I found my answer and you guys were right...
Quote: "The headphone circuitry in the FLEX-5000 uses Output Coupled Load (OCL) 
amplifier with a 2.5V bias."

Headphone requirements for the Flex 5000

That sucks, love my earbuds, they're so much better due to weight, but don't 
really want to mess around adding a capacitor.

Thanks,Mike KF9AF

A couple of separate answers:

- Capacitors in series do roll off the lows, but if you pick a cap whose 
reactance at one octave below the lowest frequency that you wish to be "flat" 
is equal to the reactance (though you can probably get away with simply using 
the DC Resistance of the headphones for all practical purposes...) of the 
phones, the frequency response will be 3 dB down at that frequency but will be 
back to flat at one octave above the "corner" frequency. So if you assume a 
lowest desirable frequency of 300 Hz. for communications purpose pick a corner 
frequency of 150 Hz.   

- And back in the day (1920's - 1930's) the voice coil of the speaker was used 
for the filter choke, and if you look at old radio schematics, say in the ARRL 
Handbook, you will see the headphones in series with the B+ for the amplifier 
tube. But that went the way of the Dodo when transformers became more readily 
available. 

Most high end amplifiers either use a transformer, or in the case of transistor 
amps have complimentary output devices with B+ and B- supplies so (in theory) 
there is very little DC at the common point the speaker is connected to. If you 
do loose one side of the power supply the full tilt boogie voltage of the other 
supply will be applied to your speaker and you have a good chance of blowing 
the voice coil.
I have literally seen a speaker cabinet catch fire and burn because the amp 
went into DC. High quality amps have protection circuits to prevent that, but 
the Certain Vagrant (Cerwin Vega) amp that caused the fire did not because Vega 
was really cheaply designed.

There is indeed dc on the 5kA phones output.

When I plug in a headphone I hear a loud pop (almost to the

level it makes me think it'll be blown).


I asked once why on earth this is needed, and got the answer that

blocking this DC (by transformers or capacitors) would also block

the lowest audio frequencies.



I simply don't use the headphones output.

BTW: I never heard that high end audio required our equipment to run  DC 
through our voice coils.

Re: [Flexradio] Flex 500 Transverse Port

[Mike Valentine]

Bill,

I assume that the 1296 transverter is double conversion to get to 28 MHzI IF, 
whereas the 222 box is single conversion.

The extra conversion needs some take-over gain to minimize the losses of the 
extra mixer in the chain.

It wouldn’t surprise me to find out the 1296 machine has an extra 20 dB of gain 
in the system — thereby the 20 dB greater OUTPUT noise floor.

Vy 73,

Mike - W8MM

I did a clean install of pwr sdr 2.7.2. It will not recognize the Flex 
5000. The driver says: No Devices Found. I did a check of the fire wire 
board and it says it is working and is compatible. I replaced the 
firewire cable with a new one and it still does not work. Before I 
reinstalled 2.7.2, I erased all past versions of SDR and their folders. 
Then I did a clean install of sdr 2.7.2any ideas would be appreciated.

Invest in some mix 31 chokes and add them at the antenna feed point, at the 
radio and on the FireWire cable. 

Reviewing this will help you out. 
http://www.yccc.org/Articles/W1HIS/CommonModeChokesW1HIS2006Apr06.pdf

I did some tests with my vna and it confirmed that those chokes will do the 
job. It is very amazing the impact common mode currents will do.

I assume you are joking, on a flex there are no hard meters it is all

Hi Tim,

Why is it we never get anything like this here in the UK or Europe?

I'd love another Flex SDR but the prices over here are a killer ... any

Re: [Flexradio] uz7ho packet soundcard help

[Mike WA8BXN]

I've not used that program but here are some thoughts: 

Using another receiver, do the transmitted packets seem to sound ok? If so,
try reducing audio levels, there could be a lot of distortion. Also, try
increasing TXDelay, the beginning of the packets could be getting cut off.

Hi 

 

I am running the UZ7HO packet soundcard program with my flex-3000. I am

The program outputs to 11025 and I have my flex VAC line set to 11025. 

 

What's the trick?

Re: [Flexradio] Microphone Recommendation?

[Mike va3mw]

I am happy to hear that everyone is learning something about transmitted audio. 
 It can be a can or worms dicussion.  :)

I just purchased a Koss headset with a boom mic for about $30.  I love the 
headset, but the mic audio is really muddy.  I don't have it in front of me, 
but I think it was called a UB40.

Fortunately, I have a couple Heil Elements that I will use as a replacement.  
Too bad you can't just buy elements anymore.  I used my ProSet for CQWW, and it 
was really starting to annoy me after about 3 hours of the contest.   It seems 
to be squeezing my head.  

The Flex does allow for some amazing opportunities.  Good luck on Sweepstakes 
for everyone.

[Flexradio] Question on 1500 and 5000 software install

[Mike - KM0T]

Hi All,

 

I am currently running version 2.6.4 with my 5000 and its running
great.(also the 6500 on the same machine..its very cool)

 

Now, I want to run my 1500 as well via the USB interface..and I don't recall
if I installed the 1500 USB drivers when I did the install.

 

Question, do I need to uninstall the 2.6.4 version and reinstall the whole
package?   Or just re-run the 2.6.4 installer and will it ask to only
install the 1500 drivers if they are not there.

 

I don't want to just plug the 1500 in if the drivers are not installed, I
know that can be an issue.

 

Thanks for your help.

 

73

Re: [Flexradio] FlexRadio Digest, Vol 99, Issue 3

[Mike]

Hi Ken,

CWX is extremely unreliable, I have seen all sorts of problems with it,
even a complete cold boot of the PC!
I've had the same problems as you with using the predefined messages,
works great for a while then boom, goes off on one and often find I have
to either restart PSDR or reboot the PC to fix it, this is with a Flex3000.

For CW you will be much better off using an external programmable keyer,
much more reliable.

Best 73,

Mike.

There are so many variables its really hard to make any kind of estimate. If

when that time arrived and they did not have a rig in hand. I'm sure the

Re: [Flexradio] How to Connect your FLEX-6000 to a LAN

[Mike Valentine]

Greg,

The USB-to-USB opto-isolator that I use is here:  
https://iftools.com/isolator/isousbcable/index.en.php

Alas, I thought it was 10kV isolation but it is really only 4 kV -- should be 
enough, though!!  It works well.

I learned that fiber-optic cable (or opto-isolation, in general) was a great 
current-loop breaker back in the days when we had computer systems in different 
buildings in a complex fed by different utility pole transformers.  A utility 
pole lightning strike anywhere in the area (a mile away?) would wipe out our 
RS-232 interfaces in the data-MUX as well as the RS-232 card in most of the 
individual terminals.  This was traced to different "ground" potentials feeding 
each building due to differential current sharing among all the utility 
transformer feeds during a strike.

All the individual pole transformer ground-rod soil resistances make a huge, 
parallel-connected impedance matrix that plays out over a number of 
microseconds as the strike currents "find" ground.  The RS-232 lines were all 
influenced by the lightning spikes to varying degrees.  Any stroke-induced 
potential differences in the "third-wire" AC connections between buildings 
would cause ground currents to flow via the data wiring with microsecond rise 
times.

Since the RS-232 runs were twisted pair, the wiring made one-turn transformers 
over the hundreds of feet of cable run -- not unlike a bi-filar balun -- with 
the "ground" line being the exciting winding.  The "secondary" winding of the 
one-turn cable transformers turned out to be the data signal lines. Ka-boom!

We fixed the problem, once and for all time, by using RS-232-to-fiber modems.  
That way each building could have wild potential differences in microsecond 
time during a strike and no currents would ever flow between local grounds to 
induce signal port problems.  I enthusiastically endorse your short sections of 
fiber between edge devices to isolate your equipment.  I know it works well.  
That was my primary motivation to run opto cable between the router (de-mark) 
and the shack -- it'll cure the problem.  Wifi is also valid and was just 
easier than running fibre through 125 feet of already occupied conduit.  We'll 
see what I need to do next after I try the WiFi solution.

All the best,

Mike

P.S.  I was the 6'4" Hamvention red-vest-wearing volunteer sitting next to your 
booth getting schooled on ROTHR signals Thursday afternoon.

I've been doing my 'lurking' thing on this thread.  I'm very interested in your 
experiences with your USB-USB opto-isolator.  I believe I know what your day 
job is (I recall we met at Dayton once long ago...) so I would appreciate any 
input.  I spent many years building instrumentation to break F-16s and Bell 
Helicopters so nasty voltages came with the job.  I've also been reading a lot 
on inductive coupling of long run CATx and telco wiring during lightning 
events.  A group of us run a 58 repeater statewide linked system here in Texas 
and indeed we've been bitten by many many more induced spikes than direct 
lightning hits.

The moral to all this is that I would like to recommend to our rural customers 
(me included!) to consider isolating or at least surge suppressing their 
ethernet connection to the FLEX-6000.  Protection Group, the Polyphaser folks, 
has a line of in-line Gigabit suppressors that meet GR1089 to 3KV.  True 
isolation gets more difficult.  At one site after several DSL induced hits, we 
actually purchased 2 100base-fiber transceivers and put them back to back with 
a 2m jumper.  Crude but the problem hasn't been back since!

Mike, any insight you might have would be greatly appreciated.  I can't wait to 
get my 6700 too and it will be on the air 24x7 just like the 5000 is.  I'm just 
a bit paranoid about hanging a $7K radio on my network our here in the sticks.

Re: [Flexradio] How to Connect your FLEX-6000 to a LAN

[Mike Valentine]

Perhaps I didn't explain the setup well enough.

I am not streaming over WiFi.  I am only connecting to the internet (for 
transient uses) through Wifi so as too break the shack-to-home-network 
lightning current loop.  Everything in the shack is connected amongst itself 
with wires.  I have a 10 kV opto-isolated usb-to-usb cable running between an 
IC-7600 and the computer.  I just don't like current paths available to 
lightning pulses-- too many priors.

The FLEX-6700 would potentially be connected directly to the Mac Mini via RJ-45 
Ethernet copper.  I think Tim answered my question that it "might" work OK.  If 
it doesn't, I'll just have to get around to installing the fiberoptic cable 
from by basement router up to the third-floor shack.  That'll fix any network 
problems and keep the magic smoke inside the equipment where it belongs.

Thanks all,

Mike - W8MM

[Flexradio] How to Connect your FLEX-6000 to a LAN

[Mike Valentine]

Tim, et al,

I read the FAQ entry "How to Connect your FLEX-6000 to a LAN" and found I have 
a setup not listed.

My shack computer receives a home network connection via WiFi in order to break 
a lightning-loop that had been exercised a few times in the past :-0   No more 
smoked LAN adapters, now ;-)

I'm using a Mac Mini with BootCamp and Windows 8.  

Can I merely plug the FLEX-6000 into the vacant Ethernet RJ-45 on the Mac Mini 
and have it work along side internet traffic via WiFi?

Cheers,

Mike - W8MM

I think you will find that some open source software called "jack" will
do what you want, "Split/Duplicate audio" ...

Google is your friend ... or have a look here:

Re: [Flexradio] The Dirty Little Secret of Firmware

[Mike Valentine]

I'm not trying to start something, however your definition of "affordable cost" 
leaves me a little mystified.

The overwhelming costs to do VHF/UHF (whether as an SDR or not) include every 
component of a transverter:  Mixers, oscillators, band-pass filters, power 
amplifier modules, T/R switching, etc..  There's just no practical way around 
any of those items. SDR doesn't change the reasons for including them.  The 
144/432 Flex product for the 5000 needed all of them, SDR paradigm shift, or 
not.

If these things are so trivial to produce, please show to all of us the 
complete engineering and development plan along with the sales figures.  That 
way we can all decide whether to invest in such a venture.

Mike - W8MM

BTW, I manufacture EHF receivers for a living.

Re: [Flexradio] 5000 Discontinued

[Mike]

I totally agree, the currently available "knob radios" don't have enough
embedded "lead in their pencil" ,even with a monitor port, to display the
dynamic range and manipulation we can do with Power SDR...Smart SDR is just
icing on the cake. I figure in a year there will be more slicing and dicing
as user/beta feedback will guide the Flex team to refine the unused power of
the new FPGA in the 6XXX series. QSK CW will finally come to fruition as
well as the vagaries of PC 's throwing DPC's and RF ingress problems, I
hope.

they have no idea when that "one" will arrive!

Re: [Flexradio] F3K Temperature when running QRP?

[Mike]

Hi Dudley,

Thanks for doing the test, I really appreciate it.
I've also found that increasing the  space underneath the F3K and the
metal ATU box it sits on has helped tremendously, seems the extra bit of
air flow helps to keep the temperature down at around 56c. Maybe longer
feet on the F3K would be advantageous.

I'm also running at 13.1v DC and so am not over voltage, something else
I wondered about too.

I'll keep an eye on the temperature as I get more experienced with JT65-HF.

Thanks,

Mike.

Re: [Flexradio] F3K Temperature when running QRP?

[Mike]

Hi Tim,

Stripped the F3K down, both fans working as designed.
With the case off the temp only reaches around 51c but as soon as I put
the case back on it goes back up to 60c+ ...

I've checked for dust build up etc and have blown out the cooling area
under the main circuit board, all seems clear and plenty of air flow.

I've raised the F3K up so that it is further from the ATU below it to
see if some extra airflow around it will help at all as I noticed the
bottom of the F3K does get rather warm when in use.

Running at 5w what would be a normal temp range?

Mike.

Re: [Flexradio] FlexRadio Digest, Vol 97, Issue 5

[Mike]

Hi Tim,

Thanks for the reply.
Will the unit operate if I remove the cover to see if the fans are
working or not?
Or is there a safety switch that disables TX with the case removed?

Is there a test mode I can put the radio into to make the fans spin or
do I just need to get it hot again?

[Flexradio] F3K Temperature when running QRP?

[Mike]

Hi All,

Quick  question about Flex3000 temperature when running JT65 on the HF
bands.

I've been playing with JT65 on 40m and 20m using just 5w of power and
the ALC at -0.1dB, the signal is very clean and I am getting great
results, my only concern is the temperature, it's getting up to 63c
which seems very high for such a low output level?
I have the fans set to come on at 35c in an attempt to try and keep the
temperature down.

Does anyone else see these kinds of temperatures running QRP?
Is this normal?
Do I need to be concerned?

Mike.

Re: [Flexradio] Turf file

[Mike]

Hi Jon,

Is this true?
Martin Lynch and Sons wanted £25 for the TURF file?
How on earth can they charge that?

I got mine from Klaus for free ... surely the UK dealer gets it for free
from Flex/Klaus too or do they generate their own file?
What is FlexRadio's take on this - Tim/Dudley?

Re: [Flexradio] Legacy Radios?

Legacy?
Since when did my Flex3000 become a "Legacy" radio?

I do hope that isn't the case as it was a serious investment to move
from box radios to Flex SDR, Radio and PC £2000! (Around US$3000!!) and
I've only had it a couple of years or so ... I will be extremely
disappointed if it is now a "Legacy" product.

Re: [Flexradio] Panadapter stall/pause ...

[Mike]

Hi David,

I have seen a similar problem with my Flex3000.
Klaus@Flex EU Support and I have been working on this.

I also have a "Clicking" sound at regular intervals on all bands which
shows on the panascope as spikes, the panadapter pauses with each "Click".

I am also running Win XP SP3 ...

Open the Panascope and check to see if you are getting any spikes on the
scope when the panadapter pauses.

This is my Flex-3000 This is an example of the distortion I can not get rid 

of after owning it for just under a month. I bought this from Flex. 

You are listening to a Electro Voice RE20 plugged directly into the mic 

jack on the Flex. I can plug any of my mic's into the Flex, and use their 

respective TX profiles. And I get the same result 

The first phrase is into a dummy load with 3 watts. The second phrase is 

into my dipole with 100 watts. The receiver is a Kenwood TS-950S. I set the 

audio chain up with W1AEX's excellent information from his web page.

Bill, can you describe it a little more? What does it look like on the

seconds? How long does it last? Does the noise blanker do anything for it?
Do you live in farm country (Electric fence)?

I'll be grateful to anyone who can tell me what this intermittent noise 

might be. It occurs on all bands at intervals of about 1.5 seconds. I 

have unplugged everything in the house, one by one, with no improvement. I 

have made no changes to my station whatsoever. All my power supplies--a 

big linear and a bunch of wall-warts--are quiet. 

 

This is probably of little interest to the group, as a whole, so you may

Hi Klaus,

Why can't a TURF file be released for the current version of PowerSDR

What is it that has changed so that we have to wait for a complete new
version of powerSDR each time??
Is this going to be the case for all future NOV changes??

software was more up to date. The one I saw was connected to an antenna  and 
was receiving live signals. Greg, K5GJ "drove" for the demo, and the box did 
crash once, requiring a restart, when a 3rd pan adapter display was started. 
There had been three, two had been removed, and it crashed when the 3rd was 
created for thee 2nd time. Greg predicted it would crash because it was a 6700 
running 6500 software. The box worked fine after the restart.

I was very impressed, especially with the resolution of the signals on the 
panadapter as you "zoom in" on signals. You can literally copy a CW signal by 
watching the blip on the display,  and I really like the uncluttered SmartSDR 
display. 

I'm sold, I'd love to place an order for one. I just have to convince my 
Bride...
... And sell some other radios.

However, the last 2 days I am receiving the following error message: "PDSR -

Hello Lisa,

I placed an order today. It was early eastern time and way before you woke

Re: [Flexradio] FlexRadio Digest, Vol 93, Issue 10

[Mike]

Klaus,

My F3K has the TURF file applied for the old 60m channels, will I need
to supply my NOV all over again to get the new allocation TURF file?

Also, my F3K transmits well out of the EU/UK 40m band, in fact it
transmits up into the US 40m band, so based on your statement below
about CE certification how did this fall through?

Best 73.

Re: [Flexradio] 1500 power output

[Mike WA8BXN]

How accurate is his watt meter at 5 watts? If his meter is say 100 watts
full scale with 5% accuracy, it could be off by 5 watts giving the seemingly
low power output.

he maybe reload power sdr, running the latest version, no change. This is

Re: [Flexradio] VU5K Question

[Mike va3mw]

Robert 

You haven't mentioned anything about ground buses yet?  Do you have you in 
place?

Why do you think that you have to rewrite your microphone?  What type of mic is 
it?  Can you try another mic?  Also, disconnect anything from the radio that 
you are currently not using?

Is the computer ground strapped to the radio?  Is the radio power supply 
plugged into the same power bar as the computer?  

Start simplifying things first and then add more bits. 

Don't blame the radio as many others have great success.  We just need to sort 
out your environment.

The current limiting of the power supply is well above 5 amps, so adding the
fuse might be a good idea. Otherwise, the supply should work fine.

Subject: [Flexradio] Flex 1500 power supply 

 

Greetings group, 

 

I am just reading through the installation instructions for the Flex 1500 

in anticipation of getting mine that I just ordered yesterday and I see it 

calls for a 1.5A power supply. I have a Samlex SEC-1223 power supply that I 

had for my Yaesu FT-450 that is a 23 amp supply. In 

my experience a radio will only draw what it needs, but it also says in the 

flex 1500 instructions to add a 5 amp fuse if the power supply is not 

current limiting. Any reason I should not use this for the 1500? It does 

say that the SEC-1223 has "current limiting, short circuit protection and 

over voltage protection". 

 

Thanks, Tom N2BEW

Re: [Flexradio] Problem with high DPC count after upgrading to W8 Pro

[Mike Heitmann]

Hi Les,

High DPC latency is one of  the things reported about Win8 in pre-release:
http://social.technet.microsoft.com/Forums/en/W8ITProPreRel/thread/aa16c25a-9c72-4579-ba02-cea920296271

That info is pretty old (March?). I know some have reported using Win8/PowerSDR 
with success.

Before going back to Win7 I would recommend trying to determine what is causing 
the high DPC count  (Video driver? WiFi driver? Malware scanner?). That way you 
could watch for updates to the offending object in case you want to try Win8 
again.

[Flexradio] Receiver input protection

[Mike WA8BXN]

I am thinking about putting an old Heath SB-200 amplifier on either my 1000
or 3000. There has been a lot of discussion of keying issues so that's not a
problem. I have multiple flex radios, each connected to its own antenna.
Typically I would only have one turned on at a time, or be operating at qrp
power levels listening to multiple radio/antenna combinations for best
reception.

 

Operation at the 100 watt level has not caused any problems damaging front
ends but I am concerned what might happen running around 500 watts. Any
general rules of thumb on antenna spacing and front end protection for my
situation would be appreciated. Most of the high power operation would be on
75 meters.



I would also like to know how the front end bandpass filters are switched
when power is turned off, at least for the radios I have (1000, 1500, 3000).
I am hoping that latching relays are not used and when power is off I would
not have a problem with that radio! If that is the case I may be able to
just not turn on other radios when running high power on one. 



Thanks in advance!



73 - Mike WA8BXN

Re: [Flexradio] Flex 5000 VU module

[Mike Valentine]

Bill,

Maybe you missed this from yesterday:

"Yes, a 4 dB pad in line with the antenna would be bad for receive.  I'm no 
good at making ascii diagrams and didn't have time to make a real circuit 
drawing, so my word picture wasn't clear enough.

I suggested the extra coax be placed between the T/R relay and the input of the 
amplifier.  That way, the receive path is isolated from the extra coax.

The amplifier most likely employs a DPDT coax relay (or equivalent pair of 
SPDTs) to put it in the circuit only during transmit.  The amplifier has to be 
bypassed during receive or one would have to "listen backwards" through it.

Re: [Flexradio] Flex 5000 VU module

[Mike Valentine]

Robert,

When you say "All of this padding and T/R relay seems like a workaround to a 
product that is not stable.", I wonder if you've ever operated high-performance 
VHF/UHF stations before.  The original complaints were about an amplifier that 
only required 20 watts drive for full output and not keeping the system gain 
constant over cold-to-hot transitions so EXACTLY 20 watts could be supplied.

One could make the argument that the amplifier is defective for being too 
sensitive and too easy to overdrive just as easily as making your complaint.  
The single FET amplifiers that only take a few or 20 watts to drive weren't the 
target when VU5K was designed.  All the big gun operators were clamoring for 50 
to 60 watts to drive their 3CX tube amplifiers without needing an 
interstage driver amplifier.  That was then and this its now.  So what?

Please give it a rest.

73, 

Mike - W8MM

Re: [Flexradio] Flex 5000 VU module

[Mike Valentine]

N4XE,

Yes, a 4 dB pad in line with the antenna would be bad for receive.  I'm no good 
at making ascii diagrams and didn't have time to make a real circuit drawing, 
so my word picture wasn't clear enough.

I suggested the extra coax be placed between the T/R relay and the input of the 
amplifier.  That way, the receive path is isolated from the extra coax.

The amplifier most likely employs a DPDT coax relay (or equivalent pair of 
SPDTs) to put it in the circuit only during transmit.  The amplifier has to be 
bypassed during receive or one would have to "listen backwards" through it.  

The extra coax goes between the VU5K side of the DPDT transmit path and the 
amplifier input stage.  There is already a piece of coax in the circuit between 
these points that is only active during transmit.  One simply needs to replace 
the short piece of coax already in the circuit with a piece that is "4 dB 
longer".

I hope the above is a little bit more descriptive.

Cheers,

Mike - W8MM

Re: [Flexradio] Flex 5000 VU module

[Mike Valentine]

Patrick,

Yes, of course.  That's why I cautioned to make sure the power handling of the 
coax was up to snuff.  There is an absolute power limit at each operating 
frequency unique to any particular coax.  It's hotter closer to the 
transmitting end.

All we have to do is select a coax that can handle 50 watts @ 144 MHz and we're 
good to go. It's on the data sheet for the coax in question.

For instance, the 150 MHz (close enough) loss for Times LMR-100 is 8.9 dB for 
every 100 feet and it can handle 100 watts average (long time constant - 10 
minutes?) power.  So, there is plenty of power (heat) margin.  If one wants 4.0 
dB loss then simply roll out (4.0/8.9 x 100) = 45 feet and put connectors on it.

45 feet of LMR-100 is safe and effective, if a little too long for convenience.

Choosing somewhat lossier coax would lead to needing less of it.  RG-178 is a 
Teflon dielectric coax that's very thin and has about twice the loss of LMR-100 
and can handle even more power.  One would only need 22-25 feet of it for 4.0 
dB @ 2 meters.

A little web browsing can be marvelous.

Cheers,

Mike - W8MM

BTW, we used to make precision terminations for 450 MHz testing by using a 100 
ft roll of rg-174 (with nothing at all connected to the far end). The return 
loss was twice the attenuation, so the reflection from the open or short at the 
far end was much weaker than the imperfections of the coax characteristics and 
connector.  Easier, cheaper, and more robust than a precision load.

Wouldn't you want to be careful regarding how lossy the coax is? Too lossy 
and you have to shed all the watts of energy in a short length of coax so 
heating might be a problem where a less lossy but longer coax/attenuator 
would distribute the heat over a larger surface area and not get so hot.

Re: [Flexradio] Flex 5000 VU module

[Mike Valentine]

Why not work around the problem by making an attenuator to knock the 52 watts 
down to the 20 watts you need?

A cheap piece of RG-58 or smaller (lossier) coax of the right length attached 
to the input of your amp is a guaranteed way to make it work right.

You want a 50/20 = 2.5:1 attenuator which is darn near exactly 4 dB.  Wind off 
4-dB-loss of coax and put it between the T/R relay and the input of your 
amplifier.   You can use your watt meter to prove you've done it right and test 
the power output before you hook it up.

One caution, make sure the coax can handle 50 watts @ the frequency of interest.

Bonus advantage:  The 4 dB pad will make the amplifier think it's in a pure 50 
ohm system instead of looking askance at the output impedance of the VU5K.  
Potential instability problems from things popping outside the Smith Chart 
circle are magically pulled back inside ;-)

I just love pads!

[Flexradio] Flex 5000 Power Button

[Mike - KM0T]

Hi all, just got my flex-5000 going again here and the power switch does not
appear to work.  I noticed it a few months ago that the flex was "on" when
it should not have been.  I have tried to turn off with the blue front
button, but it won't go off.  So I have been pulling the DC plug.  Plugging
the DC back in directly, the flex waits a few seconds and turns "on" without
touching the front panel on switch.  Seems to be working fine other than
that.  Any ideas to "reset" the switch, or is it just a bad switch - failed
in the on position.  Note that the switch does light up with the blue color
when the DC power is applied.

 

Thanks and 73

Re: [Flexradio] FLEX-1500 Amp - TenTec 518 (418?)

[Mike Valentine]

Model 418 Amplifier Questions

http://qrper.com/2011/10/ten-tec-answers-your-questions-about-the-model-539-qrp-transceiver-and-model-418-100-watt-amplifier/


*


QRPer: A QRPer would like the Model 418 to be easily interfaced with other QRP 
radios and kits with a drive level low in the one watt range. Is this possible?

Ten-Tec: This is a good point, and a strong point with the Model 418 amplifier. 
The Model 418 will be adaptable to any QRP transceiver out there.

QRPer: Will all modes be accommodated as well? (AM, CW, SSB, RTTY, PSK, FM), 
including those with full duty cycle?

Ten-Tec: Yes.

QRPer: For desktop use, one QRPer suggested TT could add the tuner into the 
amp, if there's no room in the 539.

Ten-Tec: No, we would not put a tuner inside the amp.

QRPer: What are the minimum and maximum drive levels for the 418? One QRPer has 
a SDR project that will output 0.5 - 1.0 watts, but also would like to use it 
with a 516. Assuming that with the 539 output of 10w, it outputs 100w, but what 
might one get with one or two watts? Are there attenuators that could be 
switched out for this purpose?

Ten-Tec: Again, the Model 418 will work with any transceiver out there. You 
must keep in mind, though, that it will adhere to FCC regulations regarding 
amplifiers. As such, it cannot produce more than 15db gain. Five watts in will 
produce 100 watts out. If your transceiver produces more than 5W in-and that's 
perfectly fine-the Model 418 attenuates, so that no more than 100 watts leave 
the amplifier.

Re: [Flexradio] VU5K End of Production Notice Questions

[Mike Valentine]

Dearest Jim,

Since DownEast Microwave has plenty of Temwell helical resonators advertised on 
their website with a really recent issue date, one might be curious as to what 
Flex's experience was with that vendor.  I found out and completely sympathize 
with Flex's decision.  Temwell's replacements for Toko helical resonators may 
be fine for experimenting, but may not be so good as a reliable vendor of 
ready-to-go production parts.  Unacceptably high levels of re-work can 
completely kill the business plan of any product.

It's a real shame that Toko couldn't make enough money to keep their resonator 
line going.  Toko has always made parts for us on which one could rely in a 
production environment.

One sees plenty of T2FD lookalikes on the roofs of Federal buildings all across 
America.  ALE?

Maybe the best antenna solution is a very large discone antenna like the one
at the old missile site near Tucson, AZ.  Unity gain but very large
bandwidth.

A very-common, no-tune RX antenna is the Tilted Terminated Folded Dipole 
(T2FD). And if the termination is built to handle enough power, it can be used 
for transmit too. Here is a good construction article for one.

I have an M2 7&10-30LP8 log periodic up at 120 feet that will do wonders as an 
input to the Flex-6xxx receivers.

http://www.m2inc.com/pdf_manuals/7%20&%2010-30LP8.pdf

It covers 40M-10M very well and makes an interesting "monitor" antenna on 6 
meters with lots of minor lobes shooting off very which way.  My rotator was 
inoperative while PJ6D was in on 6 last summer and I couldn't quite make the 
QSO on the ill-pointed 6 meter beam.  I switched to the log and was able to 
make the QSO off one of the many lobes.

Think log periodics...several good ones out there that cover 14 - 30 MHz,
giving 5 bands and some do 10 - 30 MHz.  Stack 'em and they are very
competitive.

Chuck K1KW - check out my QRZ.com<http://QRZ.com> picture for such an antenna.
