Subject: CW tone seems to be breaking up on Rocky

Send Email Send Email
 
RXTX Ensemble cw note is breaking up on Rocky. With the head set pluged into
the line out on the computer I hear the same thing. It seems like processes in
the computer are causing the interuptions. Is this common? Is there something
that can be done to prevent this from happening? I am ready to build a external
transmitter to get around that.
Memory is 2GB, cpu is a 3.2 g pentium, sound card is motherboard realtek and
same thing with external sound blaster XFI. This is very disturbing since I am a
100% only cw op.

All the SDR sound cards for a single rigging needs to share a clock.  Rocky is especially finicky about this.  You'll see a lot of folks using delta-44 sound cards because those voids and pops will transmit where they shouldn't as well.

There are but, they are grossly greedy, W&S details in Radcom or google.
When I say greedy US$1=GBP1 X2 + p+p GBP 5.

I'm sure someone may have one of the earlier kits unbuilt they could
sell you at a fraction of the price, Good luck with the 2E0

Waters and Stanton used to advertise very old softrock RX kits, may
still do but I haven't checked for a very long time.

The Softrock gear is designed, kitted and supplied by Tony (KB9YIG). The
only source is kb9yig.com.

This is not a commercial outfit, Tony does all this as a hobby and when
kits are available you get some warning on this list but the best hope
is to check his site regularly as kits never stay around very long -
sometimes they are gone within an hour.

Alternatives are the SR63ng from yoyodyneconsulting.ca - an all SMT
clone of the no longer available SR v6.3 from Tony.

Dave (wb6dhw.com) describes the UHFSDR transceiver, an all SMT board 1 -
700 MHz. Supplied by the Silver Fox, see Dave's site.

For sure if someone has a kit unbuilt they wish to move on I would be
interested. Please e-mail me at chris@... if a reply here
is not deemed etiquette. If I buy direct from the US has someone got a
link to the sellers site please? Thanks for the info and good luck

Thanks, I see how this works now. I might be safer building a Softrock
Lite IF first and using it as a panadaptor for my old Yaesu FT-902DM
boat anchor. I need to check its IF, but what are the chances of me
finding one of these in kit form? Can you use the receiver kit as a
panadaptor for another rig, or do you specifically need the Lite IF
kit? Is the Lite IF kit much simpler than the full receiver kit?
Thanks.

IMHO go for the ensemble RX kit,
I did the older Lite kit first and didn't realise what I was missing.
Assuming you get exactly the right crystal and the I.F. is in good shape
you get a small fraction of the features of the larger kit.
The work is probably 40% of the full kit for about 15% functionality.

The kits are built in steps with good error checking tips, the danger
doing a lite kit first is rushing to get it done (it's a small PCB how
long can it take?!) and at the end finding it's fine but not exactly the
full SDR.
Maybe we should coin the term SDIF to denote one foot nailed to the floor.
Don't get me wrong I loved my 40M kit (later tweaked for FT-102 IF) but
didn't realise how being frequency agile the RX could do all that and
more for a bit more work.

If you want to check a Ensemble RX II try sdrspace.com (download the
full program) and if there is not one available I'll put mine on for a test.
I could also give you the option of trying a Creative X-Fi USB, Xonar,
or Roland USB sound card. You will need a decent sound card to make the
most of SDR.

Then you are in at the deep end with Si570 and regulator coming towards the
beginning of construction.
If someone has NO SMD soldering experience then maybe a Lite is best,
certainly if there is a projected use for it.
Nothing difficult to solder, fewer coils to wind, a few less steps with file
manipulation and software.
And good results are possible with ordinary soundcards, make your mind up
about that later.

I'm not quite sure why people talk up this SMD stuff, it's not like it's
0402 or .5mm pitch blindfold.
To me a decent pair of tweezers and angle the board so that your wrist
is at the right angle so its not straining, bluetack the pcb to a tray
and move around when required. Magnifying glass or webcam if the
eyesight is a bit lacking.

Unless someone is out in the woods and can't talk to someone who has
been in electronics some time in the last 20 years there is help out there.
If you really think it's that much of a big deal I'll stick the Si570
bits on and test for him. Or Skype with webcam some build tips,
Teamviewer the PC to watch drivers are installed.

OK a 96kHz sound card is a luxury but a a half decent soldering iron
isn't - why don't we be a bit more positive and recommend some things
learnt from all this combined enthusiasm?

From my time in this group fears of SMD is the problem.
Many posts are aimed at overcoming this fear. The Lite version is always
recommended to beginners, many who have no experience or connections with the
electronics trade.
I am not suggesting it is difficult but I do not think those two components are
going to be child's play for a beginner. They comes before any of the easy ICs

Offering to do it for someone seems to be somewhat negative, just let them get
some experience. A functioning Lite is a good way to get that experience.

Next comes all the posts saying how easy it is to reflow SMDs.....

Stu, I couldn't agree more, although a little practice with junk SMT PCBs probably wouldn't hurt for those with absolutely no SMD experience.  SOIC packages and 0805-size passives are pretty easy to handle with just a little practice, and can be soldered either with wire solder or with solder paste applied using a #22 syringe.  I recently assembled a board using 0402 parts, with little trouble.  I've found that finer-pitch parts like the microcontroller and DDS chips in my kits are more difficult, so I install those before the kits are shipped.

Through hole parts are getting harder and harder to obtain, so we will have to embrace surface-mount assembly or give up homebrewing.  

For really fine-pitch parts solder paste applied with a solder stencil is a must, in my opinion.  I buy stainless steel stencils for $99 when I have boards made; that might make sense for club or group projects.  I've also heard of $25 mylar stencils, but have not tried one yet.  Probably should.

Don't use the solder paste Radio Shack sells!!!  I like Amtech LF-4300.  In the US, I believe you can buy it by the syringe from Stencils Unlimited for about $20 plus shipping.  One syringe will do many boards.  I don't know of a source in the UK, but there must be one.  You wouldn't want to have it shipped from the US, because it is supposed to be refrigerated in transit.  The cold pack the US supplier uses wouldn't last long enough for a transatlantic shipment.

Decent hot-air rework tools are available on Ebay for around $100.  A good quality (i.e., Weller) butane soldering iron with a hot-air tip also works well.  The toaster-oven method of reflowing also works well, as long as it is used before any through-hole parts are added.  

For production, I work in batches of five PCBs.  I apply paste using a stencil to all five PCBs, then place all of the 100 nF caps, then all 10 uF caps, and so on until all SMD parts have been placed on all 5 boards.  That takes about 40 minutes per board.  Then 3 boards go into the oven for reflow, which takes about 7 minutes.  Then the remaining 2, and then (after they've cooled) I add the through hole parts.

You could use the oven method for assembly in stages, as long as you don't use the oven after adding any through-hole parts.  I've found the oven method works best of all.

Tweezers work well, or you can make a vacuum pick at a very low cost from a ballpoint pen, an aquarium pump & tubing, and a square-cut hypodermic needle.  Stu's comments about being able to rotate the PCB so your wrist is at a good angle is absolutely true!

Yes, that's what I found. I wondered if it was me.
It worked when I tested it for Mario a few months ago but the release version
seems to have grown a bug.

Any sdr should work ... just need to set the lo to the proper freq - UHFSDR is
X2 the IF and the Lite would be X4 .... and maybe buffering if the IF output

Thanks, I see how this works now. I might be safer building a Softrock
Lite IF first and using it as a panadaptor for my old Yaesu FT-902DM
boat anchor. I need to check its IF, but what are the chances of me
finding one of these in kit form? Can you use the receiver kit as a
panadaptor for another rig, or do you specifically need the Lite IF
kit? Is the Lite IF kit much simpler than the full receiver kit?
Thanks.

I am certainly willing to give it a go. I would like to practice on
some SM components first though. I am unsure how to go about that
though. I am happy to buy some cheap surface mount devices to
"sacrifice", but I would need a suitable PCB board to solder them to.
Anyone got any tips for cheap ways to practice? i couldn't TIG weld 2
years ago, but am now so so with aluminium and reasonable on
stainless. I remember when a BMC "A" series engine seemed complex and
re-building one was a fearful undertaking. I now tackle F1 engines
without any great concerns. Practice makes perfect and all that.... ;)

Chris,
 
You can get a board by finding an older computer board or consumer electronics.  The older stuff used larger size components.  Hit it with a heat gun and shake the parts off.  You might also be able to use the oven at 500 F and then shake.  Just don't let your wife see you.

Thanks for the replies. Right now the softrock is put away and will give it one
more shot today. My PC does not have pci slots. I thought it would be a good
idea to get rid of the big box. :)
Is SDRSharp ready for TX now? Is the file ready to download?
I wonder if setting rocky priority to high in task manager as well as the sound
cards to high would would end the break-up of the cw tone.
If you hear a lousey cw signal today, it could be me.

Thanks and 73's

Not yet. Only RX for the moment, but I'm working on it.
How much cpu does Rocky use on that pc? Just to be sure of the nature of the
problem, try to get two cpu measures: one with visible main window and one when
reduced. Rocky not being known as CPU hog, I'm suspecting the graphics.

It's just plain a bad idea to cook PCBs with lead solder in an oven
you use to cook food with.
