I know Rakon makes their crystal filters in France. Don't know about the others but I doubt they are manufactured in the U.S. Mike N2MS

All, I have a Timewave PK-96 modem hooked up to a Kenwood TM-V7a via the 9600 port and wish to do 9600 packet over FM VHF (145.090). However, it says in the manual to measure the deviation from the

I'm running Mint 21 Cinnamon. I just downloaded NanoVNA Saver from github ( NanoVNASaver.linux.zip <https://github.com/NanoVNA-Saver/nanovna-saver/releases/download/v0.5.3/NanoVNASaver.linux.zip> ) I

There are quite a few companies making & selling crystal filters. Probably mostly offshore, but perhaps not. Rakon Murata ECS and a bunch more You might also find crystal filters intended for defense

You may want to check with Rob Sherwood on the filter impedance. He used to sell them for Drake Rigs: <http://www.sherweng.com/filters.htm> Network Sciences made the filters and are still in business.

hi Gary @w9td@... <w9td@...>, how re you. Did you understand gate R used w/ FET stacked topology? If so, can i ask you a details. kind regards, Em qua., 9 de nov. de 2022 às 17:29, Gary

Great, thank you for the lead. I use the shell that shipped with Linux Mint, so it's likely bash? I will tinker with it. I have mostly avoided the terminal, but there is too much radio that can only

Just for giggles here are some plots I did of a Drake SL6000 7-Line filter with the NV. 73 -Jim NU0C "Jim Lux" <jimlux@...> wrote:

Sort of - the S11 measurement will tell you the impedance "looking into" the filter, and if you were looking for a perfect match, then you'd want to feed it from the conjugate (same R, flip sign of

Great discussion for me.. I haven't bought a VNA yet but my first project is to sweep some Drake filters too. Mine are from a T-4X 5.645MHz. I don't know what the termination is supposed to be but

Hi, Maybe these videos help ? It is a series of 3., watch the #100, #101 and #105 to have a complete view of a choke effect. https://youtu.be/kMlKfHHR8FY 73, and best wishes for the new year ?

True, but we are looking for a general idea of the shape of the filter. We're not doing rocket science or production specification (at least, I am not). The 7-Line filters ARE 50 Ohms as already

Build a shell script with the two following lines, and run that. #!/bin/sh ~/.venv_nano/bin/activate python3 nanovna-saver.py then $ chmod +x nanovna.sh $ ./nanovna Change /sh above to whatever shell

Hallo Sigi, i cant the driver installed in windows, i dont now why. I see a driver but jot the cypress driver.

Please note that filters need to be terminated with the proper impedance (ofter NOT 50Ω, sometimes with a reactive component and sometimes diffent at input and output)) if they are to display the

If you have the driver installed you will find a new comport in device manager when connecting the nano v2.. Select that port in the soft (upper left corner)... And click on connect. Should work

Hi Jim, Thanks so much! When you had mentioned checking the filters on the Drake site, as the older Drake filters can be a little suspect, I thought we’ll I have a nanovna so I might as well try and
