Ignatio (EB4APL) has contributed a schematic drawing showing the connection of the Arduino NANO and a QRP Labs Si5351A module using the Experimenter Board as a platform. I've added it to the regular E

Hi Nivar_P. Your writeup says you are using two identical cores with identical 8 turns of bifilar windings configured to work as a 4:1 balun. Not sure how you are electrically interconnecting the bifi

Most of the requested PC boards have been mailed. There are still a couple of folks who have not yet responded to e-mails. If you had requested boards in December, but have not heard from me in the pa

Shucks.... misspelled my own e-mail address... trying again :^)) The FedEx guy dropped off PC boards yesterday, and I have sent e-mails to all who had requested boards prior to placing that order. The

I've only just started building the PHSNA but already the UNO and Ad9850 with the Arduino and Windows software has allowed me to generate test sigs proving one of the band pass filters in my G3TSO mul

There have been a few inquiries here in the group, and I've gotten a few others direct, about availability of PC boards. The cupboard right now is completely bare, but I'm willing to put an order toge

Hi Richard, Yes, I have included an Etherkit Si5351 board into my PHSNA. Photo attached (I hope). Yours might be rat's nest but mine re-defines the term ;-) My Arduino code started with Nick's Windows

I'm doing the final setup on the PHSNA, crystal test jig and return loss bridge. The homebrewed PCB RLB of W5JH design checks out at 35 dB. The direct RF output from the SNA to the log power meter is

I'm starting out with an arduino nano v3.0 pro mini (on board FTDI and 5v regulator) I'm hooked up to a 1602 LCD display on D4 to D7 and D12 to D13. My DDS AD9850 module (125MHz clock) is on D8 to D11

Hi, Several times that I started to use my PHSNA I got a totally flat sweep graph. It was caused by forgetting to connect the 12 V supply, and since the Arduino is powered by the USB connection, the p

Hi everyone, Latest update. I zeroed out the polynomial coefficients in the Parameters.txt file. Next, took new data with the homebrew VE7BPO -10 dBm sine wave calibrator (checked against the K3NHI CM

Hi, I guess this must be operator error(s), but I'm struggling with this. Using Arduino 1.6.6 with the .ino files downloaded from Windows PHSNA, rev 1.6 dated March 31. I read the previous posts on th

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 da
