The nanovna saver is not currently being developed because of the busy programmer. Latest Version: 0.2.2.1 (Python 0.2.2) https://github.com/mihtjel/nanovna-saver/releases/tag/v0.2.2 The 2.8-inch core

Hi everyone, From all the firmware versions for the nanovna-H (original) what firmware do you recomend to take the most from the nanovna-saver? Or, is the nanovna-saver agnostic to fw version? Cheers

Howdy Pablo! This virus should has thrown the world into turmoil... I hope it turns out to be a minor virus, not as bad as the flu. As far as coax for antenna for an H/T, I would assume around 145 MHz

Hi Roger, Thanks for this, your results look very similar to mine, there is a slight difference in the frequency of the dips but I assume this is due to differences in the mix of the core material,

Tindie out of stock - I have purchased their last unit :)

Kerr, I wound two 1T to 8T impedance transformers using BN73-202 binocular cores and insulated, solid, silver-plated wire-wrap wire. They were connected back to back and the 1T sides soldered to SMA

Pablo you can also take a look at this video that is very detailed on how to determine the impedance and velocity factor of any unknow coax cable: https://www.youtube.com/watch?v=TpIIftvQPFM

Saludos Pablo, You could use the TDR function of the NanoVNA to check the impedance of an unknown coax cable by soldering a non-inductive variable resistor (value within the range of the suspected

Had exactly the same DANG here. Totally loose display and connector broken. I was able to resolder the display onto the pcb. Took me 5 times of trying but I succeeded :-) Give it a try. 73, Arie Pa3a

50 or 75Ω, it shouldn't make a big difference unless you are wanting to push high power through it.

Hi guys and greeting from Buenos Aires, Argentina. We're in full country quarantine since thursday, I was planning on buying some cable, but our govt acted so fast that I had no time, so I'm stuck at

Oh, I really hope we will not be disappointed by Gabriel's little baby. I'm waiting too long already... Less noisy I hope at 900 MHz than VNWA and NanoVNA and finally 2.4 GHz! Reinier

Hi Herb At least the Danish postal service has been notified 12 days ago, and it is just a matter of being patient ? -----Oprindelig meddelelse----- Fra: [email protected]

Thanks Herb, yes I thought so, but wanted to be sure. Jos Op 22-3-2020 om 15:15 schreef hwalker:

Hi Herb and others As soon my SAA-2 arrives (I ordered it on the very first day it was offered by Tindie, and it has left sender country on the way to me) I will issue relevant data for the SDR-Kits
