Hello, There is a trick that is used by people that work on particular frequencies for example in power microwaves 2450MHz.(oven-people) They use a lambda/4 line at that frequency with a typical 50

Hi Herb, at that time, during the further development of EU1KY AA, DH1AKF conducted frequency extension experiments where the bridge circuit levels were modified. Simultaneously, he modified the

Group members who are into hardware experimentation might be interested in trying some of the latest improvements reported by Pmax65 at, " https://github.com/hugen79/NanoVNA-H/issues/14 ". He is

Dear Conrad, I'm a member of NanoVNA-F development team, because of BH5HNU's personal problem, the hamelec aliexpress store is no longer selling product now, but we'll reopen a new store soon, it

Sound like NooElec is selling an older version board. Anyone know what is the version number of the PCB? (3.1? latest is 3.3) Is this a NanoVNA-H or a clone?

Yes, I got the feeling that the -F version was a bit less advanced. I have the standard model, and will eventually upgrade, but I will make a decision about what to upgrade to later.

Here is a picture story presented as 5 figures which hopefully will clear some questions. In the five figures we start with a circuit representation of a dipole which is a bit unusual as it has a

Thanks for the clarification! For some reason the Version 2 devs think that they can only offer a $50. price-point device with a small display. For some reason they don't see that offering a "B" (or

Thanks Larry. I had looked at a lot of posts regarding "battery" but had not seen a report of similar behavior. I will take your advice.

Hello Erwin, I am quite happy at number 2 ? Good to see you here. 73 Conrad PA5Y

My mistake David. Conrad

That's the one, many thanks to all. Regards Conrad PA5Y

Hello KV5R, sure. Good questions and good points. I'll try to go through your note step by step question with a response. ================== Rather than constructing, would something like an

The unit is defective as there is no timeout built into the firmware.? What you are seeing is a defective battery charger chip that are found on units from certain Chinese manufacturers.? Contact

I received a new 2.8" NanoVNA about a week ago purchased on eBay from a US supplier "thanksbuyer-hobby" . It appears to be complete but without an EMI shield. I have calibrated and used it

=============================================================== David, Currently we have the following products being sold: 1. 2.8" NanoVNA (Hugen's MOD of edy555's original open source project). All

Isn't there a 3rd path - the "2"? "H" has the best firmware but older hardware & small display, "B" larger display & some hardware updates, but older firmware, "2" about to release newer hardware &

Greetings Alan, You have proposed an idea on this subject that my old brain can almost understand! :) I have a couple questions, if you care to elaborate. I will intersperse them below. Rather than
