Bonjour ,Hi i have been searching in old topics what i am experiencing and i did not find anything. So did you ever notice that the reading of S11 is pertubated if you touch or not the nanovna. even

Hi Rune I do not know if you noticed my information on how to measure high Z component where the port extension is an important addition. Likewise a new screen display/window showing Rp and Xp would

Hi Rune I will modify my calibration document and maintain the 50fF (it might be forgotten to delete/change) and adjyst the dealy accordingly. I think this is the safe way. I will also add

Not sure. I often use port extensions when measuring a DUT with a different cable. Being able to quickly rotate the cable away during regular measurement is a very nice feature. Also it would help if

Greetings to the Battery Group :) I have some batteries for Samsung Galaxy S3, 2100mAH, that are a just a bit smaller than the nano and would fit inside with slightly longer standoffs. But here the

Hi Rune , in my opinion ,the right place of the port extension control , is on the calibration menu. Best regards Maurizio IZ1MDJ

Hello Kurt, a value of 1 should work. But I haven't had time to test it thoroughly :-) I will look into making a value of 0 work as well, or give an error if it is not possible. "Port extension" delay

TL;DR: if unsure, ONLY use cells >= 2400mAh and <= 10000mAh with the Nano. The reason for the upper limit is a bit more subtle; it's due to the fact that the charge cut-off current is fixed (100mA),

The IP5305 can not limit current to a "safe" value for the battery because it doesn't know what the battery's capacity is. It simply limits current to 1.2A or whatever the USB port can supply,

Interesting.? I am not a trained I.T.person, have been using Linux since 2002, and have had pretty much no problems with it at all.? I do, however, find Windows to be a royal PITA, on those rare

Hi Run Aha, thank you for the info. That is a nasty one ? Then a value of 1 might me OK ? Kind regards Kurt -----Oprindelig meddelelse----- Fra: [email protected] <[email protected]>

Hi All, I used the battery from a Boefeng 888 which was broken down to make an Allstar node. Labelled as 2.2Ah, and includes a protection board. 73 Barry G4MKT

A number of forum members run their NanoVNA on Mac computers.?Please do some searching around the message topics and you will find a number of threads on this and the issues you might see.? ...

Hallo Karsten, Ja, if I read you correct, I 100% agree. Vy 73 de Andy

The 'H' on a NanoVNA-H supposedly means it is a Hugen device. Is there anything keeping the cloners from labeling their devices as -H ?

To the question "Trickle charge current is also mentioned on the spec sheet as being 100ma, not enough to kill a 400ma cell." If you read the datasheet fully, you find this lines: #Low Battery voltage

hi all, forgive me if I missed any previous post on this subject. Is it possible to run a nanoVNA on a MacBook, any problems, how to, s/ware etc ? thanks Wayne VK6EH

Agreed. But I was not saying that it should be the case, or was the case ;-) I believe that Li-Ion prefer a typical 0.5C most of the time, so at the worst case lets assume a NanoVNA charge controller
