Re: Greetings from a new user

 

Hello--

Given a clowder of? stray PCs currently running various operating systems (Linux Lite,
64-bit Windows 7, 32-bit Windows Vista,) can anyone recommend a step-by-step installation
process for any operating system and any version of nanoVNA software?

Helpful suggestions are appreciated!

Thanks, and 73--

Brad? AA1IP

Re: CMC - I PROMISE FINAL.......FINAL.......NEW INFORMATION

 

Dave,

Nice list.
What was de S11 on all of these measurements? (S11 as SWR)
Especially interested in the measurements where the loss in dB is more than 0.5

Re: CMC - I PROMISE FINAL.......FINAL.......NEW INFORMATION

 

For the finale (If it is possible), let nanoVNA be included in the "game" with chock baluns.. Too many people do not have access to professional VNAs and it would be interesting to show a chock balun of the measured, connected to the nano VNA and what sees H or H4 for example.
Including the steps on how to measure chocks with nanoVNA and get most important info as this in yours .docx files even with + / - 10% errors or a bit more will be great appreciated.
Many Thanks for all Job done to You and all others !!
Best Regards.


Re: Display freezes moving cursor with touchscreen #nanovna-v2 #crash

 

Hello DiSlord,

Could you provide the link for the new firmware version (.bin) for Nanovna V2, please?

I used NanoVNA-QT application to flash a .bin file on my Nanovna.

Regards,
Simone


Re: Display freezes moving cursor with touchscreen #nanovna-v2 #crash

 

Freeze on marker drag fixed in last versions of firmware.


Re: NanoVna H-4 stucks

 

Folks,
In order to make the DeFuse GUI better understandable, I created a version with better command labels.
You can find it in thew forum's FILES section here:
/g/nanovna-users/files/Miscellaneous
Follow the instructions in the zipped file.

Re: Display freezes moving cursor with touchscreen #nanovna-v2 #crash

 

Hi Ray,

Thank you for your feedback.

I have the following version:

It has 3 buttons on top instead of the rotatory switch. Once frozen, I tried to play with them as you suggested, both clicking than keeping them pressed but it did not work in either way.

Can you provide more details on what you do to have it responsive again, please?

Thank you,
Simone

Re: Differences of H4 and SAA2N #buying #features

 

Ken,
The H4 works to about 1.5GHz, uses SMA connectors, a plastic box, and has a 4 inch screen.
The SAA2N works to about 3GHz, uses N connectors, a metal box, and also has a 4 inch screen.
The hardware designs are significantly different, and they use different firmware. Either one can
work either standalone or with Windows 10 (and other) software.
RANDL.com is a reasonable place to buy either if you are in the US.

Re: NanoVna H-4 stucks

 

Good morning!

Thank you for answer.
I uppgraded analyzer to version 1.0.45. DfuSe prongram say that upprade
succesfull. But when I press: Leave DFU mode, I get little little alarm

Any idea whats wrong?

Hey Fred, good to see a familiar face here. I hope you and all are well. I have retired and moved up into the north Georgia woods and very much enjoy a totally quiet location in the woods.

Re: MORE CMC SINGLE CORE DATA

 

Manfred,
Re: There are always those snakes who will seek
to take advantage of people's ignorance. If boosting their victims self esteem
by feeding them wive's tails and simple explanations that serve their purpose
they will readily do so.
You asked:
"Are you maybe thinking about clever businessmen who sell $1000 copper-free, super-low-distortion power cables to HiFi fans?

Or were you thinking about companies that sell $300 professional, ultra wide frequency response microphones to hams, to be used for SSB transmission? :-)"

High end gear for low end applications doesn't bother so much. I was thinking more of lossy folded antennas made of rotator control cable, promoting the G5RV as equally effective on all bands, the low loss of using OWL totally makes up for a badly mismatched antenna system, etc, etc. And my favorite, diplexer = duplexer. Of course, we could talk all day about audiophools and oxygen free copper speaker cable.
