Bravo, je n'avait pas pensé à cette éventualité. Merci de France.

About a minute in, I swear he said NanoDNA. Was that intentional?

[alanwolke]

Just be careful, the output of the NanoVNA is a square wave, thus has a lot of harmonic energy. Of course, it’s very low power.

[LukeFrench]

Really useful, just used this to set up a radio. Many thanks 😀

[drspastic]

i like to use it when traveling with a vx7r to decode ssb. just dial the same frequency in both devices and vx7r on am mode. anything will do as an antenna on the vna. you can also use it for 6m dx cw

I need your wisdom for finding books about radio circuits(actual circuits) as all I can find is either RF engineering books or some basic electronic books, I need books where I can learn the tips and tricks for designing practical circuits on my bench.

If it only had a variable output in dB from 1mW down I wouldn't have to spend £80 on an RF signal generator :(

Hi..
what about the CH1?

Is there a connection between the VNA and the receiver, or the signal is just transmitted? And another question, can I use it to calibrate an S-meter?

[SamLAB-yx]

Can i use the N VNA to control a vco for spread spectrum freq hopping porposeses ?

[tommihommi]

You don't have to set start and stop frequency to the same to get CW, you can just select "CW frequency" below that to get CW mode

[tsynet]

Thanks on the tips, but how to stop the transmission? After enabling CW, it is always transmits, even after turning it off/on. Thanks.

[MrDaim]

Do you realise that the nano emits a square wave? So you're spattering multiple harmonics, most likely outside the ham bands.

Also, are you aware of the sensitivity of these instruments to feed line capacitance? A great way to blow up a nano is to connect it unprotected to an antenna, where feedline capacitance can easily charge to a level where it blows the instrument.

[TheMariepi]

so that the nanoVNA has a fixed frequency and does not sweep, in stimulus you mark the same frequency in start and stop

[Ray_Piste]

I there, i was watching a video where one of these nanos picked up the very small signals even from a car key. I was thinking of getting one but can they record and capture it then see if i could interupt or flood the relevant frequeny and play it back

[davidj.wilcox]

This thing has so many possibilities. Peter will soon have another book for sale.

[cwguy]

I've always liked how you test devices beyond what their intended use is. That's how we learn and discover - thank for sharing this!

[valetech]

would it be possible to hook this up to a computer and use it as a wspr transmitter?

[alanjones]

Great ideas. Where do you get them from! Can see this in more test scenarios now.

Thank you for the video. 73 from DL5CH
