Hi hwalker One comment to you BNC calibration test. Are you cal kit home made with three bulhead adaptors where 2x100 ohm SMD fitted to the centerpin as load and the open as well the load has the

Hi. I just bought the NanoVNA and want to make some tests on some LNAs.I have 2 SMA 20db Attenuators.How to setup the VNA & how S11 is important in the Tuning.Very thanks for answers.Regards Sid.

Edit: A warning. I was inspired to use another USB-C cable. Very strange is that with the supplied USB (black) cable the NanoVNA won't start connected to the PC. I did a test with a self-purchased

With all that new firmware, I now work a lot with the NanoVNA connected to the PC. With my modification in message # 967 I can start the NanoVNA with the placed switch on the IP5303. But once

Hi Andy, Hi, Andy, but your call also seemed familiar to me ;o) Yes, it's true, on 17.07.2017, in the morning at 04:30 I had a direct hit in my LF antenna. The antenna was disconnected but

Hi Hugen, this sounds very good! Are you looking at expanding the frequency/measurement range by a change of components as well? I'm happy to hear that you will stay consistent with the NanoVNA, but

Using the cho45’s web interface can use nanoVNA very good on the phone , I think this is a very good expansion screen scheme. I'm also trying a 3.5-inch LCD, maybe working with the STM32F303 to

This is the latest version of the edy555 that includes the TDR feature. I have modified the touchscreen calibration value before compiling and can be used directly with the 2.8-inch NanoVNA.

Done

Maybe it would fit better in the Firmware section? ;-) Good work! -- Rune / 5Q5R

I pulled edy555 release 0.1.1 and merged with my scan command extension /g/nanovna-users/files/NanoVNA%20PC%20Software Contains an experimental TDR functionality and 1500MHz as upper

Yes, I did send him a pull request to have the my scan command in his code as his scan command does not work

Hi Andy, what errors are you seeing? -- Rune / 5Q5R [email protected]> wrote:

OK thanks for the feedback. I just wanted to know before I took the time to start testing, and possibly avoiding a learning curve. That would have been nice, because I can get vnaJ working fine on a

No, it cannot. I spoke to Dietmar about him making changes or facilitating others by opening the source, and he was not in favour of either case. -------- quote ----------- Yes, I’m aware of a bunch

According to S1P file that you shared above, your BNC has VSWR=1.008 at low frequency (below 100 MHz) up to VSWR=1.0953 on 800-900 MHz.

Hi Erik, As far as I could tell, the "official" firmware also moved to 1500MHz now. I see there's also a scan command in the code, but it's commented out. Have you had any communications with edy555

I may have misunderstood your point here, as I am not 100% sure of what you are saying. I apologise if I have misunderstood you. There’s no way you can *measure* a 53 dB return loss. You can get

Gary, Edy555 increased the stack size of one of the threads and as my firmware is tracking his changes (as it is identical except scan command and 1500MHz upper limit) I will be releasing a new

The challenge in the resizing - it already works for most of them - is having the "square" ones not resize out of square ? I've tried to get that to work, but I think they need another shot - and a
