Re: [Flexradio] Dual RX with VU5K

2013-01-01 Thread Jerry Coufal
Tim,

If the RX1 tap is not in the RF signal path why do I hear the public safety
channels on RX2 when RX2 is set to 10 meters and RX1 is set to 2 meters and
the Receiver 2 antenna selection is set to RX1 Tap?

This  is associated with the problem reported on 9/6/2011   12-16-11 on
Ticket #509 / DE662.

Thanks - Jerry

[Flexradio] RX2 CAT Control When Using CW Skimmer

2012-09-09 Thread Jerry Coufal
I would like to use CW Skimmer on the 5000A with RX2 / VFO B. I have VAC2
set up to send RX2 audio to CWS but the band data showing up on CWS is for
RX1 / VFO A. Click / Tune is changing the RX1 / VFO A.  I am using DDUtil
between the radio and CWS.

Is there a way to set up the CAT control to CWS for RX2 / VFO B so the RX2
band data shows up on CWS and the Click / Tune will control RX2 / VFO B?

Thank you- Jerry

Gerald - Thank you for the reply, and thanks for the information on the
helical filters.

 

Here are the specific issues I was referring to:

 

5/27/12 Ticket #1430:  The peak position data on the right side, below the
panadaptor is not reading correctly.  This happens when RX2 is turned on.
When RX2 is off, peak position data reads correctly on RX1. This was
identified as a possible bug in PSDR 2.3.5

 

4/25/12 Ticket #1258: VU5K 2 meter and 70 cm transmit output power is low at
around 45 watts. This was turned in as software defect #703.

 

4/24/12 Ticket #1258: Squelch does not function on RX2 when tuned to 2
meters FM. Can't turn squelch on and off.

 

9/6/2011 - 12-16-11 Ticket #509 : When I have RX1 set to 2 meters (any
Frequency) and RX2 set for 10M at 29.070 I am receiving a Denver, Colorado
public safety FM station on RX2 ( This issue was determined to be a probable
software defect, transferred to the engineering group and logged as DE662.

 

12-16-11 Ticket #509:  During the discussion of the apparent intermod
problem on RX1-2M / RX2-10M it was discovered and confirmed that the display
on the console regarding the antenna configuration don't sync up and is a
known bug.

I miss the old bug tracker page on the Flexradio website. Is there any
chance of seeing that return?

 

I want to say that the technical staff on the Help Desk at FlexRadio are the
absolute best. They are extremely knowledgeable of the SDR products, always
go out of their way to assist and are quick to sort out the pertinent
details to get to the core of a problem.  I very much appreciate the

I fully understand at some point all products, ham radio or otherwise will
cease to be made. My disappointment is the VU5K is on the short end of the
cycle which I believe will impact the incentive, and rightfully so, of
Flexradio to work out all of the issues with the existing VU5K modules. I do
appreciate your commitment to the on- going support of the VU5K but also
realize it may not be practical to continue support  for long. I am a
capitalist down to the core, and understand the good, the bad and the ugly
that goes along with it.

 

With regard to the intermod on the VU5K 2 meter band, I guess I didn't
understand that an external  front end filter was required. I failed to
glean that information from all the online and offline documentation as well
as from the Help Desk support ticket requests I have submitted.

 

There are always trade offs in design.  In order to achieve a 1 dB NF for
weak signal work on 2m, it is necessary to eliminate band pass filtering on
the preamplifier input and to run high gain through the system.  This makes
the front end more susceptible to overload from out of band signals.  A band
pass filter on the input will get rid of these problems at the cost of noise
figure.

 

 

Can we anticipate some fixes in upcoming PSDR releases in 2012 for some of
the apparent software issues associated with the VU5K?

 

Can you detail the issues you are referring to?

 

 

I am really interested to know specifically which components in the VU5K
module are obsolete with no follow on replacements. Is this something that
Flexradio can share with us?

 

The sole source helical filters have become extremely difficult to get and
we have had yield problems with the ones we have gotten.  There is no
alternate source.  

 

Thanks very much - it is fun to get to communicate with the top guy.

 

Always glad to talk.  73, Gerald

Flex stated that they are not going to make new VU5K assemblies past a final

build, but they will keep a large number of spares available. So you
already 
have the assurance that you are asking for. 

And I would also like to point out that the worlds of electronics
manufacturing 
and machine equipment are very different. My company (automotive
electronics) 
struggles mightily to maintain component continuity; we are constantly
testing 
so-called drop-in replacements and tweaking designs to adjust to the
reality 
of the components available. 

Unless you are in the industry, you probably do not have visibility in to
how 
short the life-cycle of particular components can be. Silicon manufacturers 
compete fiercely, and are constantly churning components. There are
certainly 
long-lived components available, but it's almost impossible to build a
modern 
high-performance ANYTHING out of a bunch of reference parts.

In my opinion, Flex need to assure to his customers a long time life of all 
o his product because it is part of his marketing strategy selling SDR 
products. 
A Part that cannot be available must be replaced by another, better that the

new one, this is always possible, maybe it cost some money but it is 
possible. 
I have CNC machines in our factory and at least during 10 years of their 
life we can get replacement parts for electronic control of them. 
I think that the 5000A is still less than 10 years old . 
Anyway I am sure flex will do his best to give us support for this nice 
transceiver for a long time, so I am not worry at all.

Does it really matter which part it is? They have bought a bunch so they can

They have announced they are discontinuing the product so a detailed list 
really doesn't accomplish much. As my wife says, it is what it is (??)

Mike: Good explanation - Thank you

I agree with you, intuitively this makes sense.

The VU5K is now history. A sunk cost for the current owners. I suspect it
won't be cost effective to repair if it did fail. It was a gamble that
didn't pay out, but it's not the end of the world at $1.2k.

You point out an inherent risk, short supply life of components, for newer
faster moving technologies. This kind of problem could occur with many
products including the follow on series 6000. For this kind of stuff I guess
I just expect more of a lifetime than a couple of years.

It is disappointing because the VU5K never did work correctly from day one
so I haven't really used it much. There are a number of issues, like I hear
more public safety channels in the 2 meter band than I hear ham radio
operations. I always suspected this is more due to software boogers in the
PSDR integration than with the hardware and felt these problems would be
resolved with time. Now that it is being discontinued I have a whole lot
less confidence of resolutions.

I guess I view the VU5k analogous to the Spruce Goose.

When these kinds of things occur it is hard to walk away without doing a
little PM'ing.

Large is relative to the number of devices in the field. It's also
dependent 
on the individual parts. It's rare for small-signal devices to fail; 
high-current devices will fail more often due to junction erosion,
insulation 
failure, etc. 

And I can't stress enough that it's virtually impossible to design
exclusively 
around the expected supply life of components. Silicon companies provide 
advisories and roadmaps, but still will discontinue (or substantially
change) a 
component on very short notice. My company had two high-volume components, a

USB transceiver and a regulator, discontinued with NO drop-in replacement 
within the space of a year. And these were popular components that we alone 
consumed tens of thousands of per year. We had to ration products and almost

ran out while redesigning and qualifying replacements. 

Look...I am not reflexively defending Flex; I'm not a fan-boy and would be
the 
first to call B.S. if I thought it was appropriate. But again...I do this
for 
a living and it's getting harder every day to write and execute a product
plan 
that takes into account the shrinking life-cycle of many critical components

A large number of spares depends on how many units have been sold and the
MTBF 
of the identified spare parts, especially the critical parts that have been 
discontinued. 

Not a simple remove and replace, the future of the VU5k will take someone to

troubleshoot the problems down to the component level. Oh joy! 

I just wish that Flex would have designed around the long lead time parts.
They 
did not, so the ones that own the VU5k will have to deal with the
circumstance 
and hope that their module does not fail.

Everyone needs to understand that 100% of the products from all amateur
radio vendors will cease to be made at some point in time.  Some soon and
some later.  Component life cycles are turning faster than ever and it is
utterly immpossible to plan.  End of life of a critical component can happen
with little more than a few months notice and you are forced to make a
lifetime buy if even available.   It is simply a fact of life in our
business.

 

On another note.  The reason you are hearing public safety is that the VU5K
is designed for very weak signal work.  It has a 1 dB noise figure on 2m,
which is achieved with high gain and a preamp without input preselection.
If you put a bandpass filter on the front end it will cost you a little
sensitivity but will get rid of the intermod.  There are always tradeoffs
like these.
