Hello Lisa,

I placed an order today. It was early eastern time and way before you woke 
up (I assume). I haven't heard a thing and I am really looking forward to 
receiving this mid week. Can you look up order number 2263-6363--4508 and 
let me know where we stand please?

Great presentation!  I tried the I2C port connection without things working, 
and will try your suggestions, I use VSPE and DDUtil so those are not issues.  
Really like VSPE after some learning curve.

Thanks for your effort!

straighten out my printout quite a bit... need a few more contacts to do
side by side comparisons...


When I looked in windows vac was set to 48000 but nothing else... 48000 was
where my flex was set, and what vac siad it was using...  i set everything
to 48000 and ther was no change... then i went into the vac control panel
and set it so it was force to 48000... previously the set up allow it to
range from 11025 to 96000... the current format always said 48000...  after
reboot this helped alot...

Short update.

There's been a bigger response to my video on the Heros Preselector than 
I expected.  I did promise in the first  video that I would provide 
information on how to get to the unit tracking the radio. Unfortunately, 
I ran out of time and so this had to be put into a second video.


For anyone interested this video can be found at: 
http://www.youtube.com/watch?v=87TI9rXxGYg


Many thanks for all your kind comments, I hope the videos prove useful 
enough to help you make an informed decision should you be contemplating 
one of these units.

Craig, I've had mixed luck with Macs Š

* 13" Black MacBook, early 2008 (Win7-32bit) ­ works great!  It's currently
the backup PC for my Flex-3000;

* 21" iMac, mid 2011 (Win7­32bit) - also works great!  I use this with my
Flex-3000.  Never had issues;

* 27" iMac, late 2009 (Win7-32bit) - suffered from periodic DPC spikes that
I could not isolate.  I sold it and bought the 21" iMac;

* MacMini, mid 2010 ­ significant issues with high DPC caused by nVidia

found the driver wanting and stopped using it.  Problems with video

Does anyone have experience operating the Flex-3000 with Bootcamp on an
older MacBook Pro?  I have a 2008 MBPro with 4 GB RAM that I want to
dedicate to running the Flex-3000.

How about experience using an older iMac desktop computer?  My wife needs a
new computer, so another option is to use her 2007 iMac with 4 GB RAM with
the Flex-3000.

Lastly, the current Mac Mini model still has a FireWire 800 port.  Does
anyone have experience running the Flex-3000 with a current or older Mac
Mini?

Please folks, the Heros VLF converter is vastly more sophisticated than the
lower priced units with limited filtering from Palomar (which I own) or
Jackson Harbor or the others. The Heros is very fairly priced. 

Still, most of us will NOT benefit from the Heros unless we're in an area of
very high RF density. My $89 Palomar works great with my 5000. 

Here are details on the impressive Heros VLF converter:

The advantage of a preselector is not that it provides more gain, but that
it reduces the power of undesired signals at the input of the receiver.

Whenever you pass two signals through a nonlinear device, and that would be
any amplifying stage, any mixer, any detector, you get intermodulation
products. As you pass more of these signals through, they all intermodulate
together. In fact, if you have really strong signals, the intermodulation
products can themselves intermodulate with  signals and other
itermodulation products. The result is spurious products all thought the
receiver. And even the noise power can be intermodulated up to the
receiver's passband resulting in a higher noise floor. The earlier in the
receive chain you can reduce or eliminate unwanted signal and/or noise
power, the better your receiver will perform.

In the olden days, most receivers had decent preselection as a way to
eliminate images. Eliminating lots of unwanted signal power was an
unlooked-for side effect. Then we got broadbanded receivers that
upconverted and didn't need preselection in order to eliminate images. And
these receivers even tested well ... on the bench where only a few signals
came in the antenna port. But once you plugged in a real antenna,
especially one that was relatively broad-banded, and all that cruft came in
and intermodulated with everything else, you got crappy receiver
performance.

Now there seems to be some idea that SDRs suffer more from this problem
than do other receivers. This is not the case. In fact, since SDR does
conversion to digital early in the receive chain, they are
LESS susceptible to this problem. The DDC/DUC (direct conversion) SDRs like
the new Flex 6xxx series is going to be even LESS affected by front-end and
first-mixer IMD. (In fact, as long as the ADC is not clipping, the DDC/DUC
radios should should be darned-near textbook perfect in their response and
behavior.)

But in the mean time we have radios like the 1500, 3000, and 5000. They
will benefit from preselection, to a greater or lesser degree, depending on
the amount of unwanted signal power arrives from the antenna. The greater
the crap (technical name for unwanted signals) coming down the feedline,
the more a preselector will help.

Re: [Flexradio] Heros VLF Converter

2013-01-14 Thread Robert Costa, KB6QXM 
Jeff,

I did not say sensitivity, I said selectivity. I want to eliminate or reduce 
intermods.

My Flex is plenty sensitive. As the front end is broadband and there is NO 
filters outside of the ham bands and I am a SWL, I thought that this would help 
with the selectivity of receiving short wave broadcasts.

The reason I like my Flex is to have 1 platform as a basis for 160-70 cm. 
Receiving above that is the job of my IC-pcr1500 for my public service 
monitoring.

My interest in radio communications extends from DC-Light. IMHO, there is more 
to radio communications than just ham radio.

Robert

" wouldn't the pre-selector help with selectivity issues on the 
general coverage of the Flex?"


What problem are you having that you think a preselector will help with?
Lots of hams read about a preselector's gain and think DX will be 20 dB more
copyable. THAT's certainly not going to happen. As long as you can hear band
noise drop when you disconnect the antenna you have plenty of sensitivity.
And just about every receiver made since the 1960s has tons of sensitivity
even on the highest bands. 20 dB improvement could also be achieved by
turning the audio gain all the way to the right or by sticking your head
into the speaker. You know that's not going to help.

Yes, if you're next door to a VOA transmitter additional front end
selectivity might be useful but only if the VOA is causing a problem.

A preselector is necessary for any serious use of my Flex5K anywhere outside 
of the ham bands below ~ 20Mhz, and it can and does help at times even above 
that. The input impedance of the Rx section is rarely 50 ohms, even in the 
ham bands in many cases.

Regarding the Heros preselector: that's another waste for almost all U.S.
hams. But maybe a nice addition if you live in rf-noisy downtown London.

Brilliant! Well done! While many argue from opinion, you demonstrate.

But I would like to make one point here -- that it doesn't matter whether
the radio is an SDR, hybrid, or pure analog, if you remove unwanted signals
before they get to the active stages, the receiver will work better.
Period. So, if you are dealing with strong, unwanted signals, you should
remove them in order for the receiver to perform its best. Some sort of
input filtering (preselection) is advantageous.

Re: [Flexradio] Feld Hell

2013-01-14 Thread Jim Jannuzzo 

Steve,You may be on the right track with the sample rates.  PSDR sends data 
back and forth to DM780 through VAC lines.  If any of the three are set to a 
bps that is not an even multiple of the other two, you get dropped bits, 
truncated bytes, and bad words. You can actually get weird results and high CPU 
utilization.  Look at the sample rate used by Windows.  It's in Control Panel, 
Sound.  Each sound device has an Advanced tab, which allows you to set the 
Quality.  Use 16 bit and set every VAC Line to the same setting that you're 
using in VAC and PSDR.I use 192K for PSDR and VAC, and so set the sample 
rates in WIndows to 192K for VAC lines in playback and record.  Speakers and 
MIC get set to the even multiple of 48K just for giggles, and because I don't 
know the interactions of these sound devices in Windows.   Jim KJ2P

Re: [Flexradio] Feld Hell

2013-01-14 Thread Steven Catani 
Thanks all,
 I have been able to confirm the previous experiment..

When in a fldigi based feld hell qso.. with straight printing on
tx(reported)  and rx i turn dm780 on... printing immediately become wavy...
as so as I shut off dm780 the lines straighten out

PSDR is set to 48000, wdm-KS stereo( i have the same effect if set to MME).
VAC says it is in 48000. I can't find anything in dm780 to set the sample
rate but I did find a screen which says 48000 stereo is a supported
configuration..

any thoughts?
