REF: /g/nanovna-users/message/13681 Hello, again. Well, after the Special Interest shown here, we would like to inform you that, in direct contrast with what Gary O'Neil, N3GO

I'm a little bit disappointed; i measured a CW 100MHz output from my NanoVNA-H received one week ago. The reference of my frequency meter is a 5MHz G3RUH GPSDO and i get a 99.99144 MHz (~ -85.5 ppm

Thank you for your quick reply and data-sheet's link. Rudi

try to see https://github.com/mihtjel/nanovna-saver/issues/125 and

The 50 ohms cables as far as I remember were rated by different manufacturers as 50 to 52 ohms years ago, so my guess is that 51 ohms is on the ballpark. It is also a standard resistor value. Try to

After calibrating, I connected my nanovna to my VHF antenna via a brand new 75 foot length of 50ohm DX400MAX coax. The SWR measurement oscillates up and down every 4MHz or so (see attached). These

Hi, Is it posible for add the big CH0 screen info in version 0.7.1-20200321 by edy555 ? Tnx Andy - ON7BA

Bob- thanks will give that a try. Dan KC2STA -- Dan Ziolkowski KC2STA SKCC #4290T Ubuntu LINUX

Hello, Can somebody give me the 26MHz oscillator reference for my NanoVNA-H ? Many TNX in advance. 73 QRO, Rudi, HB9ARI

I think you need to explain "doesn't seem to be working." Does that mean that when you turn it on, absolutely nothing happens? Likewise, explain "don't get any results." Nothing appears on the screen?

Luis, Yes, it should also work with an UNUN. A caveat: It should give a low VSWR (high return loss) when properly terminated. --John

... saving me the cost...

By the way. This case was an especially a good deal for me because it was just a short 20 min drive from the store for me to go pick it up,swing m the cost of shipping. I also picked up some cheap BNC

The Nanovna-saver program has an issue where you can try and calibrate it and it doesn't work. Make sure you use the "calibration wizard" in the nanovna-saver program under the. You will soon learn to

P.S. The tubing was placed back over the stylus and the the assembly was held in place while running the beads of hot glue. This provides for proper alignment and acts as a heatsink for the pieces of

The attachment for the stylus is two pieces of 3/8" heatshrink tubing I shank down around the stylus. The tubing can then be loosened for a good fit by rolling the stylus between two hard surfaces.

Scan for 10MHz to 500MHz. Your antenna is probably too long and will not show on the 140-150 MHz scan. WO4ROB ________________________________ Sent: Wednesday, May 20, 2020 1:38:05 PM To:

Hello. Let us ask, please, two "rhetorical" questions, which are addressed to all readers of this thread: - Is there anyone, ever, wondered, in any similar to this, under discussion, case - that is

I ran a test case with a 4:1 xmfr after adding resistive loss to the xmfr. A plot of return loss (from s11) and then transmission loss (from s21) is provided. Looks like 1/(1-|s11|) where S11 is
