These are very useful cheap'ish boards for creating 35MHz to 4.4GHz ..

yes, that's the kind of thing I was thinking of..

I might leave some feedback on github (did it also in the past). But first I need to understand what might be the issue. As Chris says, it is all a little too confusing... I am still busy untanging it

Hello Kent, That sounds like interesting work you do. Sorry for this off-topic response but, G8EMY. What a coincidence! _Norman, G8EYM._ Sent from my GNU-Linux ThinkPad.

Mark, as I understand it, your nanoVNA would have to run its synthesizer on one fifth of your operating frequency, and so you would have to use the fifth harmonic. That's because the third-harmonic

Hi Norman Yes, CE and the FCC would consider that sweeping signal a Transient during any compliance testing.Might even get it declared Spread Spectrum hihi.? ?(That's what Lorawan is doing)?

Mark, Since you only want to transmit one of the harmonics from the NanoVNA you will require a bandpass filter for the 900 MHz. band. Here is a link to a good online tool that can design many types of

For filter design and performance, you might try Elsie: http://tonnesoftware.com/elsiedownload.html <http://tonnesoftware.com/elsiedownload.html> It's good for lumped element filters. My first knee

The original author of NanoVNA Saver, Rune, developed a very nice program and graciously shared it with the user community. He was very responsive to comments in this group and corrected bugs quickly

FCC Restricted Bands (Part 15.205) is likely to be relevant, where the requirement is equivalent to -41.2dBm/MHz eirp (assuming a 0dBi antenna), -41.2dBm/100kHz 960MHz-1GHz, and -49dBm/100kHz at lower

Alternative suggestion give them ear plugs. Ha ha De K8HTB Joe

It could be an artifact of how scikit-rf works or how NanoVNA-Saver is coded. For example, the uncalibrated nanovna returns gamma for ch0 as reflected measurement/source measurement It's easy to

Hello Kent, Mark introduced himself as an 'RF newbie' and I was, somewhat clumsily, trying to point out that transmitting RF is not an unregulated activity. I understand that very low power CW

Amateur radio transmissions require id, as do broadcasts (both are for the purposes of "communication") but other transmissions generally do not (radars don't ID).? As it happens radars aren't legal

DisLord, First, THANKS for all your efforts!! You guys do an amazing job, I want to make sure my comments are not taken as I think people are not working hard….. ;-). I’m only trying to offer my

Hi Norman On this side of the pond the FCC does recognize the need to radiate signals during testing. I have an antenna range and commonly transmit on many commercial frequencies.? I am expected to

What I don't understand: If 'weird' measurements can be handled/calibrated with code in the NanoVNA (which is a smallish device), why would it not be possible to have proper calibration, without

Good afternoon Mark, In most parts of the world, transmitting a radio frequency signal is a carefully regulated and licensed activity, whether for experimentation or any other purpose. Holders of
