HI All, For those of you that may also be looking for a power meter board, there is another source you can consider when Jim's inventory is depleted. Dick Faust, K9IVB, designed a small PCB for the

Hi All, Thank you to G3ZQC, I now have the AD-8307 Board and Return Loss Bridge PCB. So still looking for the "Crystal Test Fixture PCB" so any help locating one would be gratefully apreciated. Thank

Hi All, Long shot I know, as these are well sort after. But I have always been taught if you don't ask, so here goes: I am wondering if somebody has the following boards they are not going to

All of the PC boards and ERA chips recently requested from the "leftovers" have been mailed. sold out -, PHSNA for Type-1 DDS and UNO $4.50 sold out -, PHSNA for Type-2 DDS and UNO $4.50

One of the best would be an AD9912 DDS with a low noise 1GHz clock. Good to 400 MHz or so. Lower phase noise than the Si570 and with the internal 14 bit DAC, the spurs are quite low.

For higher frequencies, I'd suggest a PLL setup. A VCO running at the right range, also feeding a frequency divider [help square up a sine wave] and phase detector. Reference signal from Si570, low

You could look at the Sweeperino by Asher Farhan at http://hfsignals.blogspot.in/p/sweeperino.html Basic SNA using a si570 and Ad8307 power meter with 2 line display for stand alone use. He also has

Hi Jim, Thanks for the prompt response. Hardware as I have mentioned already is wired and waiting for the software . Since already one exists for HF I believe it will be only a nominal

I suppose it can be done... assuming the square wave can be dealt with. But it won't be something that I plan to work on - hardware nor software. Jim, N5IB ---In PHSNA@..., <nivar_p@...> wrote : Hi

Hi Jim, Is a HF/VHF/UHF PHSNA possible. I am thinking about Si570 chip with an Ardunio NANO controller as hardware. In fact I had already one rigged up and waiting for a suitable

Check that the libraries you expect to have are actually in the library folder. And also check that the filenames and the references in the code are the same case - apparently the filenames/library

Problems solved. As it turns out the PHSNA software was not the problem et all, I unknowingly lost power to the main board. Sorry I sent out the message without trouble-shooting more. However, I am

I'm not sure why upgrading to the latest Arduino IDE would make PHSNA fail. Did you decide to re-compile PHSNA and have a failure during uploading? One alternative to the Arduino IDE is codebender.

Hi, I dumped Gates and Microsoft decades ago and never looked back. If you are familiar with MS Windows and it's problems you should carefully consider switching. If you have a store bought computer

I recently upgraded and am running 1.6.8. I am not currently experiencing any problems. You might try completely remove all traces of the Arduino IDE and try doing a fresh/clean

Hearing your experience with Arduino1.6.8 I feel lucky not to have upgrade to it from the current 1.0.5. I use it with Win7 (32 bit) without any problems for my PHSNA. How ever I welcome a Linux

I have been receiving constant reminders to upgrade the Arduino Software and finally fell for it. My PHSNA windows version has been working flawlessly for at least a year and now it does not work at

Not much left in the cupboard: sold out -, PHSNA for Type-1 DDS and UNO $4.50 sold out -, PHSNA for Type-2 DDS and UNO $4.50 sold out -, PHSNA for DDS-60 and NANO $4.00 4 only,

Yes, I did cross the EMRFD bridge.But I have come with a half decent RF lab and working on buttressing it as well as my design abilities. My first crack at RF design concerns a Tektronix (yes..in

Some recent chatter on the EMRFD group has generated a number of new members joining us here on PHSNA. Welcome aboard! I am away for the weekend at the OzarKCon QRP conference... when I return I'll be
