... Steve, I will add your name to the wait list for V-F oscillator. I think you are #5 and the minimum buy is 10. Cost is $40 shipped anywhere if paying by...
I constructed a fixture for measuring leaded components. I used a 2" X 4" piece of Duroid PCB which is single-sided copper on a dielectric but backed up on the...

Harold et al, Thanks for the comments, Harold. In response to "how'd you do that?", I have posted three pictures of the fixture in the Photos section under my...
Thanks for the comments, Harold. In response to "how'd you do that?", I have posted three pictures of the fixture in the Photos section under my folder W8LI....
VERY Good Lou, I see now that you have both bases covered, that fixture will do both reflective AND transmission tests. Will have to make up a couple of those,...
I'm collecting parts to build the VNA. I have a large stock of BNC Connectors and cables. Has anyone constructed the analyzer and associated test jigs using...
Mike At these HF frequencies, unless you are trying to determine transmission line lengths to the mm, BNC connecotrs should work just fine. They are...
Hi Lou, I know you've had several comments, and I'll add a few more. You can use your fixture for leaded components eithet as a "Low-Z" or "High-Z" bridge (see...
One other comment, Lou: An alternative to mechanical clamps to avoid repetitive DUT and calibration standard soldering would be a suitable pair of short...
... Paul, I will definitely come up with some arrangement to clamp the DUT. I got my fixture idea from using an older LCR Meter at work. It has a separate box...
Lou, can you put me down for 2 VP oscillators of the next batch? I have one of two sets of boards ordered by M1KTA (Dominic) and we are at last getting around...
... have one ... getting ... will get ... Done. I have you down for two oscillators. Paypal is fine. Please note that the cost is higher due to the Paypal...
Hi Community, I finished my VNA today (in the basic version) and made a few measurements on Low- and Bandpass-filters. I found an astonishing match with...
Hi Pedro, I did a quick check using my W2K PC and V1.2B of VNA4win re the problems you're having in VNA4win. NA4win was enabled to do a single sweep. The...
Hi Pedro, Paul The-mis formatting of the marker frequency is an international compatibility issue; it will only occur with countries that use a comma as a...

Greg, W8WWV, and his partner, Paul Hubbard, have enabled Exeter for support now of both the first and the second VNA detectors. I have tried it with my second...
Are there any VNA want-to-builds lurking out there that have not asked to be put on my list for a Valpey-Fisher 148.344 MHz oscillator? I ask because I got bad...
Hi, Lou I like to pick up 2 osc. Not sure when I'll get to building one... Please let me know how to get a check to you and thanks for handling the order. Song...
