I'm using ComTestSerial from microridge.com. The best of all, it free! :-) 73's de Karl LA3FY

I measure transmission loss by reading the display numbers when the marker is at the desired position.? If the line is open or shorted at the far end, the R reading in Ohms will indicate loss, as it

Erik,With the battery disconnected I connected 3.7 V to the off position of the power switch and it works. If I raise it to 5V and connect the battery, will it charge and operate on battery?? I would

Rune, I appreciate all the work you have done developing and sharing this program. Really looking forward to the next version of your program when you have fully implemented the "offset delay"

Thanks all for the sage advice, and yes, I do have some cheap dummy loads on order from Amazon - but darn it they only had overnight delivery for a shipping option - lol. So yes, my impatience

Thanks Oristo, That helps. Also, I found a couple of different ways to use the Fire as a monitor. A couple require paid for apps and a couple more use remote desktop software to do it. Going to give

From: hwalker Bruce, [] On the flip side, the cost of the NanoVNA is magnitudes below a commercial VNA so you can take a lot of liberties; however, its always a good idea to adhere to "best practices"

Yes I followed the installation procedure to the letter, the problem appears to be associated with Python3.7.4 not loading Pip correctly.

Simply a bad idea and in general a bad practice! Precision terminations in general are small low parasitic devices not designed to dissipate power. You do not mention the operating frequency but if HF

And if it HF or even VHF- build your own. Dale W4OP

I think 0.3W may be critical for L calibration load. What is reason to try to use expensive precise calibration load as a high power dummy load, while you can buy cheap 5-10W dummy load on aliexpress?

I am tempted to re-purpose the 50 ohm calibration piece from the OSL set as a "dummy load" when testing a low power (300 mW) RF transmitter. Does anyone have any idea what the power dissipation limit

I never thought about using a Fire as a larger display. Larry, you speak of "side loading" an app. Pardon an old dude but I don't know how to do that. Are there instructions somewhere on how to do

Hi Kurt Poulsen, I understand you, but something is false. Best way the fully calibrated instrument. But if not available, for example if can not do osl far end calibration port extension useful. This

Hi Rune and others First of all thank you for keeping the NanoVNA-saver a clean product sticking to "transmission delays" only all the way thru. For S11 reflections the "transmission delay" is

If * CMC means Common Mode Choke * connections are e.g. Fig 3 (a) in http://lib.tkk.fi/Diss/2009/isbn9789522481870/article7.pdf * CH1 was first calibrated without CMC then that will yield transmission

all of these versions jitter all over the screen for the first few mins,none show the marker in the smith chart,anyone else get this?,im on win7sp1

Hi Rune Very probably ? Regarding the comment where to place the field for delay adjustment so the calibration window does not shadow for the displays of data it is logical to have it under
