nanoVNA vs Comet CAA-500
Does the expensive Comet CAA-500... do anything more or better than a nanoVNA? I don't believe the Comet has software apps or PC connectivity I couldn't find any comparison on the web or info by Comet

Re: Battery LiteVNA 64
Hi Marco, The cell is an 804050 (see below) which means it's 8mm thick, 40mm wide, and 50mm long @ 2000mah. I measured the thickness of the area and you should stay with exactly those sizes. The

Re: Markers keep changing during sweep, cutoff errors #measurement
Glad that worked. Saver is calculating the center freq and 3dB rolloff frequencies from the data, which will always be slightly different than the design frequency. After the analysis is complete (and

Re: Saving calibrations and measurements to VNA-View after calibrating and measuring off computer?
Sigi is correct - the only way you can save measurement data is if your nano has an SD card slot and a version of firmware that supports it. Many nanos are SD-ready; search for SD in the messages in

Re: Markers keep changing during sweep, cutoff errors #measurement
That tidbit helped thank you. When I set marker 1 = 10.7, clear others, 1 changes to 10.9999 others to 9.2Mhz I hit sweep, they change to: 1 = 10.729 2=10.628 3 = 10.830 Can i keep a marker at 10.7

Re: Markers keep changing during sweep, cutoff errors #measurement
I'm not sure (not at home with my nano to experiment), but try setting only marker 1 at 10.7, clearing the other markers, and see if the auto analysis runs with consistent results. I'm wondering if

Re: Markers keep changing during sweep, cutoff errors #measurement
The markers got changed in this screenshot from what I originally set them as, I used something like (10.2, 10.7, 10.9) Mhz

Markers keep changing during sweep, cutoff errors #measurement
I am trying to set this Nano with amplified jig up consistently. I have latest firmware on 2.8" H model. Sometimes the NanoSaver app cooperates and i can measure, sometimes it doesnt, like right now.

Hi Marco, If you're really in need of a battery quickly, you can always use a spare cellphone/mobile device battery. I have a used iPod battery powering my H4 and it's great - see if your local

Re: Deleting measurement profiles
Sorry for the confusion, Russ. What I mean is the collection of settings for a specific measurement (swr, scale, calibration, measurement range in frequency, etc.). I had several of these stored while

Re: Saving calibrations and measurements to VNA-View after calibrating and measuring off computer?
He also wants to save the measurement... No that does not work.. Except when you modded your unit with an sd card holder and use a fw that supports it. Dg9bfc sigi Am 21.12.2022 05:30 schrieb "KK4ITX

Re: Saving calibrations and measurements to VNA-View after calibrating and measuring off computer?
Keith, When you first setup the VNA you saved the Configuration probably in Zero. This calibration stays in the unit until it¡¯s overwritten by another calibration. If you save it while you¡¯re

When you say settings, are you talking about calibrations?

Thank you, John. Never thought about simply overwriting previous settings. Your suggestion works great. Many thanks. 73, Bob, KN4HH
