Hello Run, I like to use your program and I am very happy with it. You try to realize feasible expansion requests during the program development. And all for free and for the three main operating

Rune, My school days are far behind me, but I recall that different filter designs fall off in certain dB/decades (i.e. 20 dB/decade) so if you were trying to extrapolate it would definitely help to

30 : our final report 1 29 : ann : our nanovna will be evaluated tonight : /g/nanovna-users/message/3867 hello all, this is our final report on the comparison of our [nanovna] and

Hi Herb, my code thus far does indeed try to extrapolate what the -60 dB point would be. Only I'm nowhere near good enough at making calculations like this, so I'm stumbling a little. I know what the

IMO, "return loss" is a poor term. > But one used very extensively. Personally, I don't have a problem with it. Arguably, >>any<< return is loss, when sending power is the goal. In which Not always.

Hi Martin, thank you very much for your appreciation! :-) I don't know Owen, so I couldn't possibly comment on his experiences; nor will I speculate on where his heart is. I only know what impact

Mike, Google on filter bandwidth and the majority of the results will come up as the -3 dB point. Not saying the -6 dB and -60 db points are not useful info, just that the -3dB point is the common

Lower frequency limit: will be unchanged because the si5351 is still present and is switched in below 140MHz. Larger screen: we are going to use the plug-in style of ILI9341 display rather than the

Martin, You might also try using the console commands via a terminal to accomplish saving and loading configurations. If it can be done via a terminal, then you can provide that feedback to Rune and

IMO, "return loss" is a poor term. Arguably, >>any<< return is loss, when sending power is the goal. In which case, "return loss" might be power sent (since lost from return)..

I appreciate that some folks here seem interested in both. Many messages with potentially useful content already here lack context and often stray far from nominal topic, requiring "reverse

I read a recent post that said that, among hams, its become the consensus that return loss is a negative number. I respectfully disagree. Regarding return loss, I understand some think its a negative

If you ever bought one of the popular starter kits for microcontrollers like Arduino, it probably contains some suitable switches. I bought a bag of assorted varieties of these switches from Banggood

There has been some discussion about the best way to represent data measured as impedance, into an equivalent circuit. The most comprehensive of these I have seen, which my company owns, is my obsolte

That might be interesting option. I expect a bigger screen is not really needed as you should be able to run from PC/Laptop anyway. I know some might want /P but that use might be in the minority. The

Larry, Where cam I find the DFU File Manager to convert the bin or hex file to dfu? Mike N2MS

Rune,?? I checked with a friend who is very involved in such things.? I think 6db and 60 db are the normal points used for filter definitions.? For example, that is what Elecraft uses... Mike WY6K

Size matters - with consumer electronics especially. It's just the old aged who have trouble with small screens (me included). The solution is simple, design it to be compatible with both small and
