Re: New bee PCB

Hi Ron,
Sorry I was out of  home for a while. Yes, I didn't got any gerber, PCB layouts till date and need those spares at you. My personal mail id is gurudattabam at gmail dot com. Kindly drop a mail for further conversation.
Somehow I was able to collect some SMD version of AD8307, Arduino UNO and Chinese DDS board, I am going to do it with all through hole parts available to me, I wish no problem will be there as all Caps are monolithic and Resistors are 1% MFR. Also I am planning to use 2n3886 instead of 2n5109 due to non availability of later one in VU land.

Thanks in advance.

Anyone going to OzarkCon?
http://www.ozarkcon.com/index.php

The organizers would like to use a PHSNA to help test the Low Pass Filters the participants will build as the conference kit. Would be a good application for the Windows version with the built-in plotting, or a NAT version.

Nick and I won't make it. I think Jerry will.

If you're planning on going, maybe pack your PHSNA.

Jim, N5IB

Thanks for the help

Thanks to some tips and education from far more web-knowledeable folks than I, some steps have been taken that ought to clean things up a bit. Should not be a significant inconvenience.

Sorry I let that sneak up on me...

Re: Files clean-up in Windows PHSNA folder

Pravin
 

Hi Nick,
                    Finally I was able to copy and paste the PHSNA_VB.ino and Morse.ino one after other in my Arduino IDE and saved the composite file as PHSNA_VB .I also loaded it into my Arduino NANO without any problems . I made the necessary changes for DDS60 in the sketch before loading it. Now I am waiting for some PCB headers to complete the assembling of the PHSNA part along with the power meter. I will let you know how it works . Meanwhile once again my sincere thanks for your prompt help.

Subject: [PHSNA] Files clean-up in Windows PHSNA folder

 
First, I made a slight revision to the Windows version User's Guide which is now called "PHSNA User's Guide 1r35a.PDF".  This document includes a discussion of which source files must be compiled and sent to the Arduino to make it work with the Windows version of PHSNA, and some of the file names weren't accurate.  So that was just a minor correction.

Secondly, I'd like to delete all of the outdated source code and executable files from the folder.  Although they are marked "archival", I can see how the whole process of selecting and processing the right files could be confusing enough for a newcomer without having the extra junk in the folder. So if I don't hear any strong objections, I'll get rid of the clutter later today.

Let me just revisit what this folder is for and what's in it.  

PHSNA exists in several flavors including the original version where the Arduino talks to a terminal program on a PC or any other hardware platform, then the version in which the Arduino talks to a Windows application running on a PC.  There's also the NAT portable device which now has its own Yahoo group, I think.  And there could be even more I'm forgetting.  Add to that the variations in hardware and I can see how a newby could have a hard time figuring out where to grab on.  (Jim has some good guidance in his PDFs on the site though.)

Now, where was I?  Oh yeah, all the files needed to run the Windows version of PHSNA are located in the folder Windows PHSNA.

The windows program is called PHSNA.exe.  No installation is required; you just run it.  It has two small text files containing user preferences and calibration info:  Parameters.txt and memories.txt.  These go in the folder with the main file.

Along with that, the Arduino source file PHSNA_VB.ino must be compiled in your Arduino IDE and sent to the Arduino.  One additional source file called Morse.ino must be located in the folder with PHSNA_VB.ino.

Simple, eh?

Re: PHSNA DDS60

Nick Kennedy
 

Hello Pravin,

As I recall, you just put both files in the same folder and the Arduino IDE will compile them both into one hex file for the Nano.  The folder has the same name as your "main" file and contains that file and any other source files that are part of the project.

I doubt if you can compile and use the main file alone, because I expect it will be making calls on and references to the other file, resulting in generation of errors.

I *assume* you could delete references to RESET if you are using an AD9851.  Even if you using an AD9850 it would probably be OK assuming the initialization routine does what's necessary to replace a reset.

I had to ponder the "RESET" declaration a little more.  I've written a lot of programs for the AD DDS chips and don't recall ever using the reset pin.  With the PHSNA project, the basic I/O code for the DDS chip had already been written before I got involved.  So I barely noticed that it was there.

Re: PHSNA DDS60

Hi & welcome to the group,

I'd forgotten about that RESET pin and had to take a look at the source.  I see it just gets pulsed one time in the source code, in the start-up routine.  So it shouldn't hurt anything if it pulses pin 11 and there's nothing connected to it.

As far as the control byte, yes it will get set correctly at run time -- you don't have to change anything.  There's the opportunity to choose the chip type in the parameters.txt file, and you can also do it from the operating screen of PHSNA.

Regards,

Nick, WA5BDU

Measurement receiver - R1 value

N5IB
 

Glenn reminded me of the conflicting information on the Measurement Receiver schematic about R1, the bias resistor for the ERA-3+. In a few minutes I'll fix the schematic, and BOM, to clarify, and will post a fresh copy.

The part is labelled as 240 ohms, 1 W, but a note on the schematic said to use a pair of 1/2 W 560 ohm parts in parallel to obtain 280 ohms.

As usual the truth lies somewhere in the middle  :^))
R1 is not super critical, but MiniCircuits suggests values for optimum bias (35 mA)

According to ERA-3+ datasheet, for operation at 12 V, R1 should be 251 ohms, and at 13 V should be 280 ohms. Remember that there is a polarity protection diode on the board. Most folks will use the specified 2N5819, which will introduce about a 0.4 V drop - voltage to the ERA will be around 11.6 V. So the 240 ohm value is a good approximation if you run at 12 V.

If, as many will, you operate from a nominal 13.8 V supply, then the diode drop will bring you into the 13.4 V realm where the 280 ohm value is more appropriate. You might event want to use a 1N4001 diode instead, bringing you even closer to 13 V nominal.

In either case, since about 35 mA are drawn, the dissipation in R1 is about 300 mW. You might get away with a 1/2 W part, but 1 W is a better choice. I used 1 W metal oxide film (about the size of a 1/2 W carbon comp) and installed it elevated off the board by 1/16" or so.
