Hi All, Does anyone know where I can buy the 148.344MHz oscillator in the UK? I am also looking at building Dave Roberts' USB interface, are there any pcb's...
Hi Ivan, Not sure which version I have. I got my PCB from Greg Ordy. But the part number you mention is 156.25MHz oscillator, I am after the 148.344MHz one,...
Yes you can use this part number. Because it is a 3.3V part and is of a smaller footprint, for your board you would need to make a small header board - refer...

Hi all, Tom Baier DG8SAQ has made a Spectrum Analyser extension for his VNWA VNA. Could the N2PK VNA also be made to have a Spectrum Analyser extension? ...
Hi Roderick, The VNWA-SW is made in such a way that it can drive either N2PK-VNA-HW or VNWA-HW. So, much of the functionality of VNWA-SW can be explored...
Hi Roderick, Ivan has experimented with Spectrum Analyzer (SA) and Vector Volt Meter (VVM) modes with the N2PK VNA. Ivan and Dave have had some recent...
Hi It is caused by the fact that the network functions for W2K do not function properly. I avoided the specific ones noted by Microsoft as needing a patch to...
Hi I'm brand new to the group, and I love the idea of putting together this project. I really think I would benefit from a VNA of my own. Forgive me if there...
