No changes, just made it an Excel97 (xls) file instead of the xlsx that some folks couldn't open.

Thanks Jim.

 

I am working at producing a Mouser order based on the combined BOM’s for the SSNA and PM, minus my junk box parts.  Hope to have it finished today.

Re: SSNA/Power Meter PCB order status

N5IB
 

The boards left Cincinnati OH at 0544 EDT today (24th)
Maybe they'll arrive tomorrow. Not sure if DHL does residential deliveries on Saturdays.

In any event, I will be on a road trip for a few days next week, so it will be the end of next week before they go out.

Keep an eye on the SOTA announcements page for my hoped for activation of Monte Sano Mountain, most likely Oct 31.

Just posted a new BOM for the SSNA that distinguishes the 5109 and the ERA versions.

Question on the power meter board ...

Paul Schumacher
 

The power meter board has a silver u shaped trace on the top and bottom of the board
by the rf input.  Is this there to facilitate an rf sheild for that part of the board.  If so,
does anyone have a picture of how they did it?

thanks,

Paul, K0ZYV

I haven’t done it yet but what I’m going to try is to cut small pieces of copper clad and form a small enclosure.  I have some thin matl from Electronic Goldmine that is thin enough to cut with scissors.

Thin brass 'shim stock' is available at most hobby and craft stores. It can be cut with scissors and bent to shape. The holes all along those strips are 'plated through' and tie the top and bottom strip together. Small pieces of wire may be soldered through several to solder to the 'shield' material.

Okay, that area is for an rf shield I take it.  thanks,

Re: Question on the power meter board ...

N5IB
 

Yes, That was the intent. To allow you do do at least some shielding around the front end components. I have one in the works at the home QTH and will post photos when I'm done, but that will be at least a week.

I had built a prototype (homemade PCB) without shielding and it workes fine, but I thought... maybe more is better :^))

I have some 1/32" PCB stock I was going to try, if that was unmanageable then brass shim stock could be bent into sort of a quonset hut affair top and bottom.

Jim, N5IB

 



Re: Question on the power meter board ...

Garey Barrell
 

Jim -

Are you planning a shield 'wall' UNDER the board as well?? Probably not necessary with the SM version.

Is the intent for a wall or a box on top??

Re: Postal Alert - SSNA to CONUS addresses

Mark Kesner
 

Mine showed up yesterday.   No postage due.   Boards look great.   Now to get parts.   Drat!  The Dds modules I have aren't going to work.   Well have to track down the right ones.   That would've been too easy.

Thanks very much.   Looking forward to both the power meter and the SNA.

Continual Update to BOM Lists

Mike Hall
 

I noticed yet another revised BOM list. Are there any drastic changes since the Sep 13 the posting?
Boards (x2) arrived today...nice job! ...and no postage due.
Have to finish seeing what I have in the junk box and then send off to Mouser for remaining parts.

Hi Jim,
My Boards arrived in Illinois today...
No extra postage due for the 2-sets.
They look GREAT!!!.

Thanks for all your efforts,
Especially the "Added Bonus"
of cutting the Boards,...
and pre-drilling the ERA-3 hole.....

Building the Simple Scalar Network Analyzer

Jerry Haigwood
 

Hi All,

    Now that a lot of you have your boards, you will probably want to get building.  There is a preferred building sequence that will help you test your system as you build.  First, build the power meter.  Calibrate it and set the voltage output to produce +5.0 VDC MAX at -10dbm.  On my power meter, the output is set a little lower.  The maximum input to the UNO R3 is +5.0 VDC.  Anymore and you run the risk of damaging the UNO. So, my meter is set at 4.55 VDC for -10 dbm.  When you guys get to the calibration point, there are several ways to do it based upon the equipment you have.  If you have access to a HP8640B generator or other high quality generator, you can use it to do the calibration.  Or if you have a good 5 watt power meter and a QRP transmitter, you can use them.  There are a lot of different ways to do the calibration.  We will be discussing them with you.

    Once the power meter is built and operational, you can then build the SSNA.  Before you build the SSNA, try downloading the software, compiling it and installing it on your UNO R3.  That will give your little computer a quick test.  Actually, this test can be done anytime.  After building the “shield” board (the board that plugs into the computer), decide where you want to take the output from the DDS board.  Jim, has written up some options for you.  Depending on where you extract the output, you may have to modify T1 on the shield board.  More on that later.  You will be able to test the output level of your SSNA using your power meter.  You will be able to set the calibration of the DDS by using a well calibrated Frequency meter or by listen for zero beat against WWV on a receiver. 

    If we can get everyone to follow this build sequence, we can help one another, as a group, to succeed.

Jerry,

I found this on the power meter, meters and calibration.  It is from "rf workbench" 

It may be of help to us.

It built the crystal calibrate source, but resistor R  turned out to be 47 k rather than 200 ohms!

Has any one posted a parts list?
My junk box went the way of much of my stuff in our house fire Thanksgiving 2009 so I will be purchasing just about everything.

Thanks again to those who put forth all the time and work so we might enjoy this project.
