Except for the very early NANOs, mine all do well at 1 GHz for RL. Dave - W?LEV -- Dave - W?LEV

Very good point...it occurs to me that all I need to do is calibrate OSL and then do a return loss measurement, comparing the 50 ohm load with the "open" condition, and see what kind of dB difference

Return loss is a 1-port measurement, S11. S21 is a 2-port measurement. So, the two may not map directly. Dave - W?LEV -- *Dave - W?L

I remember upgrading my first nanoVNA-H (2018?) with (the then) just released firmware that allowed for up to a 1500 MHz limit, albeit with much lower dynamic range. I just upgraded the firmware to

The proper instrument to use for this application would be the TinySA Ultra, a spectrum analyzer. The input power is still a problem. Typically less than 0 dBm (1 mW) at 50-ohms non-reactive. Dave -

Exist different HC-05 modules, my old allow stable work on 460800, but last ordered allow only on 115200. Yes tou can use Serial->WiFi converter, it allow more faster speed (up to 3M) and autor

Many thanks to all. Phil

I would suggest that the TinySA ( a small spectrum analyzer) might be a better way to measure your radiated RF power at a distance. As to accuracy, what you're talking a

Fran?ois, I highly appreciate the clarification and feared this would be the case. I recently stumbled across the nanoVNA in another forum. After lightly researching the product through Amazon I

The wiki page Home ( /g/nanovna-users/wiki/12336/177482 ) has been updated by Larry Rothman <nlroth@...>. *Reason:* updated info on DiSlord's modified NanoVNA-App for LiteVNA

In the current firmware there is an option to control the device through the serial port, instead of the usb port. (Menu/Config/Connection/Serial and Serial Speed) I used a Serial/Bluetooth HC-05

With the jet lag, I dare an answer *Yes *No *Measure a power at 100 times the wavelength can be significant but how to calibrate your probe. You can only make comparative measures *It seems to me that

Hello fellow techies, I'm currently in the process of changing a test method for two similar communications antennas. The Tx antennae output 908MHz and 922MHz respectively at ~6.4mW^3. my current test

It's been almost 3 years since the previous posting. Anyone made any progress yet? -- Doug, K8RFT

Other way around. 2 degrees measured in reflection (out and back) is 1 deg one way.

Yes, that technique should work fine. [email protected]> wrote:

Just a quick update. I received several new SA602AD chips just before Thanksgiving. I ordered the "602" because that's what was in there originally. The unit calmed down considerably but still not
