Hi Paul, Thanks! No problem at all. Yousaf is my last name (it is the Islamic pronunciation of Joseph so normally much more popular as a first name). Confusing when the first and last names both sound

Yes, Shabaz, my first thought was 'Joseph' ;>) Regards, Paul

Thank you Paul for a fascinating project. I purchased my USB board set and the BOM some time ago and I have yet to finish the build. The thought that the information will still be accessible in the

Hi Brian, Re your suggestion for public access, I'm thinking that the info screen at groups and yahoo will point to Ivan's website after he updates it and maybe Dave can do the same at his. No clue

Hi Paul, I can also say thanks for the great N2PK VNA project. It has brought many hours of joy and fun in build it and using it. And improving it. And thanks to all other who also helped, thanks.

Hi Everyone, The HTML version of the paper is published, these three links below cover the 'part 1' PDF. I'm now working on the part 2 PDF, splitting that out too into multiple shorter pages too. Once

Hi I am using the myVNA 1.0.0.95 When I import a any configuration ( transmission, S-Parameters etc ) appears tick also " TDR mode only". I have to un tick it and everything works properly. Any

Hi All, Ivan has kindly added an archived copy of my now defunct website to his website here: <https://www.makarov.ca/n2pk_archive/index.html> I have also updated my QRZ page to reflect this. Stay

Hi Paul, Any estimate of how many N2PK VNA's were constructed over the years? Steve, K8JQ

Paul, Thanks for the excellent piece of test equipment. Your groundbreaking work as spawned many designs but your VNA still has tput if piece of quality test equip,emy in the hands of experimenters.

Hi all I have a problem. I calibrate in reflection mode, then I apply again the load used to calibrate and display the Xp. See enclosed the result, glitches ? Help IZ2ZNC Gianfranco

I've finished a v5.2 board and the VNA seems to be operating properly.? However there was one odd observation that I was hoping someone in the group may have seen before, or have a theory about. The

Sounds like the gnd terminal of the regulator is floating. Mine behaved normally. Gary NA6O

Thanks Gary. Unfortunately it shows solid continuity when I test it. I have replaced the regulator as well - the replacement and the original behaving the same, unfortunately. 73/jeff/ac0c

Hi I am wondering whether anyone might have a single detector PCB available. I am looking to update a rather old single detector N2PK VNA to a dual detector for use by a friend. Thanks. Bob, 5B4AGN

Hello folks, After many years of great service my N2PK VNA has developed a problem, it acts like it's detectors both have poor sensitivity. Can anyone give me some guidance troubleshooting? Drop me a

Hello All, I haven't posted in years but I need your help now. The hardware is a single detector board with Pauls original coupler board unmodified. The software I'm using is MyVNA version 1.0.0.54 on

Dave, It might seem like heresy but I would recommend that you download the software that runs the DG8SAQ VNWA. /g/VNWA/files/A1%20DG8SAQ//VNWA36.7.9.8.zip It will also control the

Greetings Q can be derived for either L or C by measuring their complex impedance .? In either case Q is a ratio of the real to imaginary values provided by the VNA.? I have recently spent
