Hi,

I tried to get informations on the int. shipping costs from DownEast on
their webpages but it seems impossible to get it and I also could not find
an emailaddress.

Can someone help?

Gerd, DJ8AY

Burch,

Get a $65 DownEast, or an AR2 or a LNA 6 meter preamp. All under $100. I
have tried them all. It will bring your SDR1000 receiver up with the best
rigs and better!

I use a TE Systems amp .5watt to 170 watts, (only need 50 watts) and a
ACOM1000 to get 1k+ output. All antenna relaying is done external to the
SDR.

Re: [Flexradio] 6 Meters

[Mike Naruta]

Hi Gerd,


DownEast Microwave recently moved their physical location
to a new manufacturing facility.  Their web site is:
< http://www.downeastmicrowave.com/ >

They are unusual because they do not use an e-mail address.


 From their web site:

Shipping and Handling charges:
You will be billed accordingly based on your selected method of 
shipment, the weight and size of the package, the value of the 
package, and its final destination. The minimum shipping and 
handling charge is $5.00.  For international shipments, the 
payment of all import fees, customs duties and local taxes will 
be your responsibility.  Approximate shipping and handling cost 
may be quoted at time of order.

Live Oak is now OPEN for business.
New Telephone 386-364-5529
Operating hours 9am-12noon,1-6pm (EST) Monday-Thursday



I presume that they are on Eastern Daylight Savings Time
at this time of the year.  EDST = UTC - 4 hours.

[Flexradio] SDR-1000 for sale

[hduff]

I have an SDR-1000 for sale. Originally a 1w radio with 4 board stack including 
the RFE board installed in Flex chassis.
Board updates applied. The Flex 100 watt amplifier and automatic antenna tuner 
were purchased later. Amp and tuner
installation was started but not completed. Lost interest...my loss is your 
gain. $1000 + shipping.

Re: [Flexradio] Manual notch filter?

[Bob McGwier]

True but I think you already know I did HMM using mixtures of Gaussians 
in 1986 in possibly the best set of  technical papers I ever wrote at 
our common place of business.   In a more refined version of it later, 
applied to Markov chains and not to continuous time and space stochastic 
processes,  it was Desjardin's vote for paper of the year because he 
loudly proclaimed it so in a meeting with management.   Between the 
several of us here with this experience, we definitely know enough to 
tackle this problem.  That said, we are definitely going to have make 
this "user tunable".   On my new supercomputer,  with a Intel QX6880  
(Core 2 Quad Extreme),  and a high end GPU graphics card with its 128 
little floating point supercomputers and Intel's top of the line 
motherboard,  I will be able run at least my Markov chain on a mixture 
of a few gaussians since the solution for the separated Ricatti 
equations for the covariance is a simple 2nd order ODE and the 
conditional mean can be quantized in time, discretized in value to the 
point it applies.  But if I were running a 3 GHz Sempron,  I probably 
would give up 10 dB of perfection to get 10 dB of suppression and still run!

The "extended Kalman Filter and smoother" is particularly well suited to 
handling the mixture of Gaussian stochastic processes in lots of cases.  
When I successfully demodulated the Soviet VEGA balloon probe 
transmission for Ed Posner at JPL this was exactly what I used.   It 
definitely paid to have a Cray supercomputer in those days!  Now, my new 
supercomputer on my desk will outperform it by a lot in scalar 
arithmetic but with SSE4 and EMT64, in all but a few examples,  it will 
nearly equal it in vector performance with the exception of scatter 
gather to the vectors of course.  For shorter vectors,  less than a 
vector of vectors,  the Core 2 Quad extreme will all outperform the Cray 
2 because of the huge startup latency in the memory bandwidth on the 
Cray.  What was it Seymour said?  Something like "It is a computer 
design I dashed off and made from personal computer parts".  The memory 
bus frequency on 64 bit wide memory is 800 MHz on my desktop!  I decided 
to forego the high speed memory bus technology, that which will natively 
support the full 1.33 GHz FSB, because Intel does not yet believe in it 
enough to put out a motherboard.  The one I chose,  takes the Core 2 
Quad 1.33 GHz FSB and interfaces it to the 800 MHz memory bus 
seamlessly.  I can live with 1.25 nsec clocks to memory!  With PCI-E,  I 
will have better I/O than we did on the Cray 2!

FORGET THE GOOD OLD DAYS.  We are in them.

Re: [Flexradio] 6 meters

[Bob McGwier]

Phil:

I measured the MDS on my radio (a beta, not a production unit but with 
all known issues fixed on the 6 meter amplifier) and it had an MDS of 
-130 dBm at 50.125.

While this is not deaf as a stone by any stretch of the imagination, I 
would suggest at least a 10 dB preamp, one of the newer ones from DEMI 
(with the improved IP3).  The nice thing about this for the Flex5000 is 
this is seamless.   There is a path for the insertion of same 
automatically into the receiver path, RXIN and RXOUT and all of this is 
handled automagically in the software by the user.  This setting will 
work by band!

I sent Richard Allen (W5SXD, SDR-1000 #1 owner) , a power spectrum of 
the bottom 192 kHz of the six meter band.  No spurs,  flat as the 
Bonneville salt flats.  My radio puts out 95 watts on 50.125 MHz into my 
Bird 43 (with the 100w proper slug) into a 50 Ohm dummy load.  The 
second harmonic is well below all required specs on my radio and Gerald 
has put an even better one (specifically for six meters)  in the 
production units.  he is really working hard to make this an excellent 
six meter radio.

The transverter agility on the Flex 5000 is amazing.  The OCXO in this 
thing is like the rock of gibraltar.   This is a very expensive add on 
in most radios,  it comes standard even in the A model.   Thus I don't 
really need to inject my rubidium 10 MHz source into it but I do for the 
sake of perfection just to make sure that circuit is working.

For your and others information,  DEMI is back in business.  They are 
answering the phone in Florida.  Pardon me if I got all of my orders in 
before I passed this along.

[Flexradio] 5K: TCXO or OCXO?

[Peter G. Viscarola]

>> The OCXO in this thing is like the rock of Gibraltar.   

It's a 0.5PPM TCXO, according to the specs.

Not to split hairs, but is there a TCXO or an OCXO in the 5K?  I added
the K2WS OCXO to my 1K, and this made me very happy.

I'd be thrilled to hear the 5K has an actual OCXO,

Yeah, but I was thinking as well of ICA here.

Also, I'm pretty convinced there is an LPC-codebook-based
heuristic version of this that depends on one-time work, s.t. the
online work is mostly search. The order of the LPC polynomial and
the size of the excitation codebook representing splatter are a
lot smaller than what you need to reconstruct high-quality signal
of interest.

I assume these weren't published in IEEE publications? (or at least 
not in something indexed in IEEE Xplore).

Where might one find them?

[Flexradio] Trying to get my Commander > Flexradio into DIGU

[FireBrick]

I'm trying to force DXLab's Commander and SDR-1000 to accept DIGU as the 
choice for rtty
Whether I tell SC to qsy to a rtty/psk spot

Presently, when I qsy to a SC spot, it puts Commander into RTTY but the 
FlexRadio into DIGL.
This isn't a big deal except when a DX station is listening split frequency.
It get my spatial relationship challenged brain confused as as the SDR 
panadaptor is opposite the WW waterfall.
Do say nothing of just plain slow making the adjustements so I can find the 
dx station and then find the preferred qsx spot.

I can put SDR-1000 manually into DIGU (which puts Commander into USB).
This works, but obvioulsy this removes the 'automatic' qsy-radiofreqbandmode 
convienence.


Any body have a solution?

Re: [Flexradio] Frequency for CW and SSB

[Mike King - KM0T]

Well, here is my 2 cents.  It may be a nuisance in general operating but its 
a must for weak signal microwaves as well as DXing.  If its a problem for 
mixed mode, its because everyone has differnt radios or set ups are 
different.  If everyone had CWU and USB or CWL and LSB then it would 
normally alway be ok.

A perfect example was yesterday afternoon.  6 Meters was open to the east 
coast to the Caribbean, but here in the midwest, the DX was coming in very 
weakly and had lots of QSB.  I spent considerable time watching a station 
and calling him on SSB.  Most guys were calling on SSB, a few were calling 
on CW.  The ones calling on CW were not being responded to by the DX.  Why 
you ask?  Did the DX not want to work cw?  Nope, all the CW was outside of 
the SSB passband.  Easy to see on the SDR-1000 bandscope.  It was obvious 
that the DX was not even hearing the CW.  These were stations with rigs that 
did not have the CW freq offset function when switching between SSB to CW. 
i.e. you would have to retune in order to hear it.

With no luck on SSB, I gave one call on CW.  DXCC #77 on 6M!  He came back 
to me on SSB without retuning to hear my signal.  We worked cross mode with 
no effort.  I just laughed when I saw other guys again calling on CW, just 
outside of the lower end of the SSB passband...I tuned away know that the 
funtion does what it is intended to do.

A few other rigs do it correctly.  Typically the Yaesus do just fine.  The 
Icoms did not until the Pro II I believe, and then yet you had to set it up 
that way.  They would have CW on the LSB side when you were on a band that 
utilized USB.

Other examples from the microwaves and weak signal work, we would try to 
work on SSB and say the signals QSBed out.  You knew the guy was there, so 
we typically switch to CW.  The guys with yaesus driving their transverters 
or whatever would pop out right where you needed them to be without tuning. 
I can recall many times loosing guys who I knew were running Icom 706s, etc. 
The fact of retuning to find a weak signal was normally a loss of a possible 
contact.

This is why I ran Yaesu radios for my VHF and microwaves 
IFser...uh.until the SDR-1000 came along of course :)

Again, my 2 cents.

I like however Frank's suggestion of making it configurable. It's just

| outside of the lower end of the SSB passband...I tuned away know that the
| funtion does what it is intended to do.
|
| A few other rigs do it correctly.  Typically the Yaesus do just fine.  The
| Icoms did not until the Pro II I believe, and then yet you had to set it up
| that way.  They would have CW on the LSB side when you were on a band that
| utilized USB.
|
| Other examples from the microwaves and weak signal work, we would try to
| work on SSB and say the signals QSBed out.  You knew the guy was there, so
| we typically switch to CW.  The guys with yaesus driving their transverters
| or whatever would pop out right where you needed them to be without tuning.
| I can recall many times loosing guys who I knew were running Icom 706s,
| etc. The fact of retuning to find a weak signal was normally a loss of a
| possible contact.
|
| This is why I ran Yaesu radios for my VHF and microwaves
| IFser...uh.until the SDR-1000 came along of course :)
|
| Again, my 2 cents.

The suggestion was a bit of a tweak at Eric, KE5DTO. Solving this
task transparently and with complete generality requires a
forward-chaining inference engine -- in short, a Prolog
interpreter embedded in the console. It may yet come to that, but
he has his hands full with more down-to-earth issues right now,
I'm sure.
