The panel was indeed made using a CNC machine. The lettering is cut on the CNC machine as well. After it is cut I fill the letters with powder coat powder, heat with a heat gun to melt the powder, sand the panel then clearcoat.

Larry,

May I ask how you created that front panel? Do you have a CNC machine? Also, how was the lettering created? It looks as good as a silk screened panel.

Nice photos Larry.  Love your front panel containing the NAT and all the PHSNA electronics/controls/meter!  You beat me to doing that J  (And great labeling on the panel!)

 

Your DDS-60 KIT, along with all others’ who ordered, is shipping tomorrow morning, as forecasted.  Good luck with it all.

I just uploaded a few photos of my Nano-DDS60 project. In the" N0SA" album.
It is going together slowly but surely. The touchscreen option is great.
Now if I only had the DDS60 kit that is on order.
The front panel is done, now I need to build a box to put it on. I think it will be PC board box with paint.

Thanks Tony. Yes, neo likes to do its own thing. Shame that it causes lost functionality though.

Re: DDS60/NANO PHSNA + Bluetooth

FWIW,
I did get the PLX-DAQ working on my Windows 7 -- 32 bit machine.  I installed an old Toshiba Bluetooth Stack (version 8) that works with non Toshiba hardware.  Its not 100% reliable in that I occasionally have to rescan.  I may look into replacing my $1.98 EBAY BT dongle with different version.

Gary you might look at my recent picture I posted in the Photos section for what I did using PCBs.  A good pair of metal shears (monster scissors) and soldering gun is all the specialty tools.

Re: Linux Software

planophore@...
 

Tony (and all),

that is interesting. I have been sort of following the rpiwobbulator but
am out of date lately.

After much delay I have started to finish up my build of the PHSNA. I
have considered just adopting what Arduino code and other software has
been put together but I just can't resist doing my own.

Hence I have been messing about with the Arduino code as a start with my
intention of using simple linux tools (i.e. terminal/modem program
interface, saving to file, manipulating with python/R/octave/gnuplot to
get to were I want to with an eye on building something more all
encompassing in python but it will be quite some time til I get there.

Perhaps as Tony has suggested, the rpiwobbulator python app would make
for a good starting point.

On another note with respect to the Arduino itself, I have been working
up some code using bitlash interpretter as it's basis. If you have been
around micros long enough you may remember the typical serial monitor
program that was very commonly used when getting a new design up and
running. Bitlash is a lot like that but for the Arduino:

http://playground.arduino.cc/Code/Bitlash

http://bitlash.net/

looks promising but I don't quite have a handle on performce yet vis a
vis straight Arduiono vs using bitlash environment.

I am off to have a closer look at the recent goings on with the
rpiwobbulator.

cheers, Graham ve3gtc

I and others have helped Tom develop the Python code for the RPi Wobbulator and it is a very useful test instrument now - it uses direct GPIO and I2C connections to the DDS and an ADC chip, so all the goodies are in one Python program on the RPi. I have some other ideas for it in the pipeline when I can find the time to implement. I have always intended to use similar Python code to talk to the PHSNA board rather than using a PC or the new NAT terminal. Unfortunately it is difficult to keep up with the PHSNA as the code for the Arduino has got quite complex - indeed the Arduino footprint PIC32 based Chipkit Pi board I was going to use with the Raspberry Pi has never had its libraries updated to be able to compile the Arduino code used on the PHSNA. I posted about this some time ago but I have never had any replies (need the 'Parse' commands implementing for the PIC32).
If you have Linux/Python experience or want to learn, you might look at the RPi Wobbulator code and see how to adapt it for PHSNA - the i/o stream would just be serial rather than GPIO and I2C, otherwise not much difference from the standard WPi Wobbulator code to display graphs in real time of the frequency sweeps.

Re: PHSNA DDS60/NANO kit -- any interest?

Jim -

Even more than a kit ..... A decent enclosure!! For many (most) of us a case is far and away the biggest stumbling block.

Take a look at

*<http://tinyurl.com/pct4n7u>*

*This guy offers this one and a similar one for the transceiver version of this radio.*

*I have NO shop capabilities available to me any more and the case is all but impossible for me. The NAT case is convenient, and looks as if it can be 'machined' with a box cutter, which is about the only machine tool I have...... I have a whole box full of 'projects', and the only one that's in a box is the Ensemble receiver!! :-) I would gladly pay as much for a drilled/painted/lettered 'box' as for the device that goes into it.

Thanks for what you do, and just remember, 'No good deed goes unpunished...!' :-)

To a rough first approximation, a kit of PCB, all board mounted components, a pair of panel-mount BNCs, a panel mount 2.1x5.5 power jack, and a pushbutton reset switch should come in between $30 and $40 postpaid CONUS, and a few dollars more for DX.

Note that this would NOT INCLUDE THE FOLLOWING
the required DDS-60 ($45 for the kit)
required Arduino UNO (about $10 for a clone)
optional Bluetooth module (about $6)
optional (?) enclosure (from $4 to $10)

If interested, visit the Polls area and cast a ballot. I'd estimate the quantity would have to be 50+ to make that cost estimate stick.

Re: DDS60/NANO PHSNA + Bluetooth

Jack D. Generaux
 

Posted photo of boxed unit with power meter and PHSNA/Nano/DDS-60 in two separate compartments.  Tried the PCB box method.  Worked reasonably well.  Big pair of metal shears, a file and solder was that was needed.  Soldered 4-40 nuts to the corners to attach the top. Surprisingly, the bluetooth still functions with the top on.  Unfortunately, PLX-DAQ doesn't seem to work with Bluetooth, at least on my first try.

PHSNA DDS60/NANO "production" board run

N5IB
 

I'm posting a survey question to asses interest in the DDS60/NANO version of the PHSNA.
Info and photos of the beta units have been posted to the Files and Photos area.

The production board will fix a couple of errors, and include a new row of pads for connection to a Bluetooth module. I'll post a preliminary layout later today. The board will be the same size as the beta.

Presuming the quantity ordered is a few dozen at least, the cost should be roughly $4.25 plus postage.
CONUS postage will be about $1, and DX should be less than $3.

Jim, N5IB




Re: DDS60/NANO PHSNA + Bluetooth

N5IB
 

You'll notice in my photos of the beta PHSNA DDS60/NANO that the DDS-60 module is mounted horizontally, using a right angle socket, with the DDS chip on the underside. This was done because of the height of the oscillator and capacitor on the other side of the board. Even then some special care was needed to provide clearance.

Conversations with George correctly point out that this scheme could exacerbate the thermal issues, since the AD9851 runs warm under normal circumstances.

In the new DDS-60 kits, George includes both a straight and a right angle pin header. He and I both recommend that, if you will plan to use the DDS-60 with the new PHSNA, you either

a) install the right angle pinheader on the DDS-60 and a vertical socket on the PHSNA, so that the DDS-60 stands perpendicular to the board, or

b) install the straight pinheader on the PHSNA and a vertical socket on the PHSNA, so that the DDS-60 will be parallel to the PHSNA boards, with the AD9851 on the bottom, but with lots of air circulation space around and underneath it.

I think (a) is the wisest option.

In either (a) or (b) above you would use the row of header pads that are closest to the trimpot R17.  In fact, I may delete the other row of pads in the next board run - just to discourage risky behavior  :^))

If you already have a DDS-60 or DDS-30, or are obtaining one of the assembled units, you should use option (a) above.
