Hi All, I'm off babysitting my grand-daughter (with grandma) this weekend and don't have the resources handy to try to answer the question. I remember all the "tone.h" and "morse" stuff from before,

Okay, back to basics. I'm going to use Term232.exe and instructions for loading for loading the code that are in the "how_to_compile_&_program.txt" file that is in some of the earlier folders in the

Nick, I'm getting the PHSNA set up (finally). LPM, SNA and Measurement receiver all built. I'm trying to get the PHSNA.exe to work. I've changed the PHSNA_VB.ino to use the AD9850, but I can't get

Looks cool, ordered one right away. Will post about my attempts at porting the sketch. 73, Mike

It depends on what ESP8266 board you use. There are several with different pins brought out. There is a new development board recently released that brings all the pins out along with built in USB

Just had this idea, can ESP8266 be used for this application in place of Arduino? AD9851 needs 4 pins and only 2 GPIOs are available, so some kind of IO expander is required. The upside is that the

Michael, Since you have not connected the can as a transformer (i.e a winding as input and the other as output) but you connected just the resonant primary between the output and the

Just a few thoughts. Looking at your test circuit, I wondered if you should hook a load to the output of the IF transformer to get a predictable result, but I also think that the dip you measured is

I've just completed building a PHSNA and Power Meter. I've put the boards in their respective boxes. I have the Measurement Receiver and Crystal Test Fixtures half built, but I thought that I'd try

Hello friends I post in my web page two new posts : 1. Arduino waveform generator and VFO with ARDUINO NANO and AD9833 ..from 0 to 12MHz. 2. Arduino simple network analyzer and AF & RF generator ...

Hi all, I want to buy a complete PHSNA with Type 2 AD9850 or AD9851 and RF Power Meter. Please contact me at mdon01 (at) shaw (dot) ca Pay via PayPal. You must be willing to ship to Me in

Nick I'm beginning to understand how the software works. I thought I was building a stand-alone box. Now that I see how the PHSNA group handles software, I'll give it a try. I'm using the type 2 DDS

Vladimir That appears to be a nice overview. I'll have to dig out all of the referenced documents before I understand what is going on. Thanks for the reply Richard

Sounds like exactly what I need. Thanks Richard

Hi Richard, It sounds like you are building one like I did. I took Nick's code and added code to use an encoder and LCD to allow a "local mode". This adds the capability to use it as a stand-alone

Okay, I found the answer myself. I did a search and found a site that added a Reset switch on a breadboard to reset an Arduino Uno. The other side of the switch does indeed go to

I am *this* close to finally getting this project finished. The boards have long since been built, and I'm getting the LPM, the SNA and the Measurement Receiver in boxes. I fooled around for a long

Hi Richard, See the attached file. It was very usefull to me. Regards, Vladimir

Well, you've got several elements of it. The PHSNA doesn't use a local display or encoder (or any other controls). There are two main versions. In the terminal version, all the intelligence is in the
