Jose,

Great! Just let me know the total cost and How you prefer to be paid...PayPal,
Check, Etc.

Thanks,

Bob,

Sounds like a good suggestion Bob. If I can't find one, I may try your
suggestion rather than a Mobo.

I went to the big-box store today and purchased a 4 oz. bottle of 100%
acetone and a bottle of 91% isopropyl.  I used q-tips and the acetone.
I now have a clean board.  Thanks for the help and sorry for all the
discussion it caused.  :)

Hello! I have unbuilt kits for sale, in never-opened baggies. I bought them from
Tony about a year ago.

I want to sell as a package:

RXTX + Xtall v6.3              (paid $61.00)
with the Si570/BPF

PA/Filter 15m/12m/10m v6.3     (paid $16.00)

PA/Filter 80m/40m v6.3         (paid $16.00)


Total paid $93.00. Please make me an offer. I do only PayPal. I'll ship free to
continental USA only. Photos available.

Send me an email off this list if you are interested.

I'll probably bring them to the Four Days In May Symposium, if they don't sell.

Thanks, 73, Frank KA8SYV at ARRLdotNET

Joel,

That is a good question.

I have always used isopropyl alcohol to remove flux. Old flux that is
stubborn may take a bit or gentle persuasion (using a soft brush or old
toothbrush) but the alcohol gets the job done. Trick is to use as to
100% as you can find, often available from electronics suppliers or as
one poster mentioned as a gasoline additive for removing water from your
gas. Methyl hydrate is not the same thing and I have found this will
leave white deposits.

Often times when painting with quick drying lacquer paints where the
solvents evaporate very quickly you will experience blushing caused by
high relative humidity levels. This may or may not be what you
experiencing and it may be possible to just brush off the white residue
with an soft toothbrush. You referred to this as a white film - is it
really a film or a deposit? There may seem to only a subtle difference
but in reality they can be very different.

see:
http://www.kester.com/Portals/0/Knowledge_Base_Articles/White_Residue.pdf

Personally I remove flux from circuit boards just because I am fussy and
it helps to better see the solder joints and any possible bridged pins
or traces. In reality it isn't really necessary and is not a sign of
improper or poor construction.

I went to Kester's website to get their take on the subject and this is
what I found:

Rosin Flux Removal

The question that frequently comes up is, do rosin flux residues need to
be removed?

Rosin flux residues are non-conductive and non-corrosive. Under normal
circumstances they do not have to be removed from a printed circuit
assembly. Rosin residue removal would be for cosmetic considerations. In
an environment where the working temperature of the assembly will exceed
200°F the rosin residues will melt and become conductive, in these
situations flux removal is required.


44 Flux Residues. The question is frequently asked, are 44 flux residues
harmful to an assembly

The “44” flux residues are non-conductive and non-corrosive. Residue
removal would normally be for cosmetic reasons. If the assembly is in a
heated environment and sees temperatures of over 160°F the flux residues
will re-melt. When liquid (at high temperatures) the residues are
conductive.

Flux Residue Removal

Removing No-Clean Flux Residues

Suggestions of how to remove the residues from no-clean fluxes.

To remove the residues of no-clean fluxes most solvents will work. The
mild solvents such as alcohol’s (Kester # 5315) work slowly, the
stronger solvents (Kester #5240) work faster. The best results are
achieved by removing the residues in an aqueous spray cleaner. The spray
cleaner can be either a batch type or an in-line type. The addition of a
saponifier (Kester # 5768) and hot water, about 130°F will completely
remove the flux residues.


Removing O.A. (water soluble) Flux Residues

It is required to remove the residues of OA (water soluble) fluxes.

You will get corrosion if you do not fully remove all the flux residues.
The flux residues from organic fluxes are hygroscopic, they contain
organic acids and they may contain halides. Over time the residues will
absorb moisture and the halides will become mobile and corrosive. This
will lead to ‘catastrophic failure’ of the assembly in question. We
recommend cleaning with an aqueous cleaning system, it can be either
batch type or in-line. The water temperature should be between
120-140°F. The important thing is to have lots of rinsing and flushing
to completely remove all the flux residues.

I've always been a fan of water soluble flux. I know some people don't like it,
but I've never had a problem with it. Give the board a good scrub under hot
water and it's squeaky clean.

Some years ago I had a job interview with a company. After the interview
they showed me round their facility which included a PCB assembly area.
I noticed a dishwasher and asked them about it - they used it for
removing the water-soluble flux from their boards.

Careful with the brake cleaner.  It can leave traces of itself behind for quite
a while and it produces phosgene when burned.  I am not sure what the burn
temperature is, but I would not be terribly surprised if you can reach it with a
soldering iron or rework gun.  A little phosgene goes a long way toward a lot of
trouble.  If you are going to use brake cleaner, I would suggest very carefully
cleaning the board with water afterward.

Good Afternoon All,

With today's kit mailing, all kit orders on my website, which show payment made,
have been filled.  Payments for kits made via PayPal automatically update my
website to show payment has been made.  However, there have been a few case
where the payment update did not work properly.

If you placed an order on my website in recent months and have not received you
kit, PLEASE let me know so that I can get things settled properly.  Please send
me the information as to when your PayPal payment was made.

Thanks for your kit orders.

Hi David,

I am not quite sure what the purpose or intention of your brief posting was
meant to be, as it is not directed at, or to anyone.

Whilst it can be a little frustrating having to wait a short time for the next
batch of kits to be produced, remember Tony does this as a retirement hobby, for
very little thanks, reward or profit.

I do not think Tony will mind me say that on several occasions, and again in the
last few weeks, he has commented to me that at times he has pondered the worth
of producing the kits and considered giving up, mainly as a result of negative
comments and remarks made regarding the kits or availability.

I can fully understand his position. On more than one occasion I have been
within one mouse click for leaving this group as a result of comments made in my
direction, fortunately the vast majority of people are appreciative of the
effort Tony and others put in , producing and supporting the kits and that is
the reason we continue.

Just think where we all would be if Tony decided to give up.

"with" needs to be replaced with"WITHOUT" in the sentence below.

Additionally, the simple hardware would be useless with the software and
firmware contributions many have made.

Sorry for the wording error.

73,

We're in the planning stages for the next batch of kits. This is a relatively complex "development platform" kit for us and it takes time, especially to get the microcode right 
.....as I'm sure several kit providers like Tony Parks can confirm. Remember, this is not a company .....just a bunch of AQRP retiree hams and there is other stuff like the Belton Swapfest this weekend, "honeydos", and interspersed naps which require attention.

El-cheapo de-icer.

Gordon MM0YEQ

Hi All,
Just rcvd a prebuilt ( from the factory) RXTX Ensemble and see some strange
errors and problems. Loaded the drivers and PE0FKO program and under Si570 tab,
I get in red Error:Si570 not Programed/ Power-down?  when I hit " Reset Si570". 
Also on the test tab, i get the message ?? RX power down??, with no info in the
Dividers field. And it does recoginize the chip and shows the device..... I dont
get it.

When I use it with SDR console, it show see signals( CW) on 20M, but a very
narrow bandwdith and I cant tune much.  Any ideas where to start?

Les
W2LPL

Ok, I am at my wit's end.  I have completed the Rx Opamps stage of the
build.  All tests were good and I receive fine except for one thing,
everything is in the opposite sideband of where it should be.  I'm using
PowerSDR (SV1EIA version) and an E-MU 1212.

Yes, I followed the directions on this page:
http://www.wb5rvz.com/sdr/ensemble/07_opamp.htm.  About 1/3 down the
page, Robby has the following, "In both the RX op amp and TX QSE
sections, the jumper links on the I/Q input and outputs should ideally
be fitted crossed over. That provides compatibility with all versions of
PowerSDR. For Rocky and Winrad it is necessary to use the 'swap IQ'
functions in their set up. If you jumper them straight across fine for
Rocky and Winrad, but you will not be able to use any version of PSDR.
(Author wired for Rocky).  Some builders (author included) have
encountered issues in this setup and discovered that the only the TX
leads should be crossed, leaving the RX leads uncrossed. Be prepared to
change these should you encounter this issue."

As a matter of fact, I started crossed, moved to straight and had the
same problem.  I went back to crossed, same problem.  Back to straight,
same problem.  I have rolled left and right (tip and ring) on the
soundcard multiple times.  When I have the soundcard input incorrect, I
receive nothing, when it's right, it's all on the wrong sideband.  What
am I missing?

I can use WinradHD and swap the I / Q channels, but then I'm about 3MHz
low in frequency.  I know next to nothing about WinradHD as I have been
using PowerSDR since I built the SR Lite.

Thanks,
Joel - W4JBB

Joel,
I think you may have only one half of the IQ signal present.
Switching the tip and ring shouldn't completely mute the receiver it
should invert the sideband position. Check your soldering from the
computer side of the audio cable up through the connector and into the
receiver.

Reverse the lines to the sound card or flip them in your software if it supports it.  I had the same problem with my RXTX 6.3 in Rocky.  I couldn't figure out why nobody was in the PSK31 frequencies but there was lots of PSK31 up a few khz.

Yeah,

I've done that - multiple times.

Right now, I'm listening to 7.1345MHz LSB on my FT-847.  To hear the same thing on the Ensemble, I have to tune to 7.133MHz LSB.  This would be correct if it's a USB to LSB thing.  BTW, the FT-847 is good to go.

Tired of screwing with this for now...

Joel,

Calibration is easily done with Winrad

I think you must have got the IQ set correctly now.
If not, note that crossed IQ only affects reversal of tuning direction and
sidebands.
It does NOT make the RX dead. If it goes dead then you have done something
wrong.
As it says on Robby's page set the jumpers so the sidebands are correct with
PSDR.
