Re: Protective Case for H4
The lid is in the picture to the right of the base and NanoVNA. I keep the case and accessories in a canvas zipper bag with allows for additional adapters for different kinds on cables you may come across. If it works for you like it does me, feel free to print it.

Re: Protective Case for H4
Seems to me it needs a lid and space for the cables, cal kit, adapters, etc.
Of course *which* adapters is a very loaded question. For the moment the very nice box it came in will do for me. Eventually I'll probably put it in a Pelican style case with a bunch of other test gear. If the FNIRSI scope gets hacked so there is better FW, a nanoVNA, FNISRI-1013D, F***Tech 6800 hacked to use a self contained LiPo battery, BSIDE ESR02 Pro and a DMM would make a really nice compact field day support kit. Have Fun! Reg |

At 1dB/div, a REFERENCE POSITION value of 14 puts a -10dB response at mid-screen. Is that what you are looking for, or do you want a more intuitive entry method? --John Gord On Sat, Jul 18, 2020 at 12:40 PM, Kees wrote:

Hi Developper Team,
Since a week I have a NanoVna-H4 with SW version 0.5.0 It is a nice instrument for investigation of someone's designs. After playing with the possibilities of this instrument I miss the vertical OFFSET menu to give the REFERENCE a value (dB) in case the measurement result is falling outside the screen. If for example I like to see the measurement result of a device with an attenuation of about 10 dB with a scale of 1 dB/div halfway the height of the screen, then I can put the REFERENCE at 8 and give an OFFSET value of -4 dB (to the REFERENCE). It may be that this OFFSET menu is discussed earlier but is perhaps not implemented because there was not enough memory for it in the NanoVna-H4. Or the OFFSET value may be implemented in a PC application like NanoVna Saver? Thank you for your effort in advance. Kees, PE0CWK |

Re: NanoVNA Saver 0.3.3 or 0.3.4
Hello, I need help. I have a NanoVNA-H which goes to 900 MHZ which I purchased from GigaParts . I ordered that to use while waiting for my NanoVNA V2 from Tindie which should arrive very soon. As discussed many times the 3.2" screens is a little small for my 72 year old eyes. So, I am trying to install NanoVNA-Savor on one of my computers for seeing better and have flexibility. I have used a MiniVNA successfully for years.
Just so that you know what I am dealing with: I have tried to load NanoVNA-Savor on three different computers -- four operating systems. They are. a. MacBook Pro with Version 10.15.5 b. Same computer with Windows 7 Pro via VMware Fusion version 11.5.1 c. laptop with Windows 7 Pro 32 bit (for ham programs requiring a PC) d. desktop with Windows 7 Pro 32 bit (my shack computer) Any one of these would have been helpful. I first tried to load Savor on "b" which loaded and opened. I then tried to connect it to the NanoVNA. It did not work. The USB cable that came with it was "C" on both ends -- useless. I found three other "C" to "A" cables non of which worked. I discovered that all of them were power only cables. I ordered a proper C to A and connected to the NanoVNA. After being connected for two seconds the program crashed (just quit completely). I started with version 0.3.4 and then tried version 0.3.6 both crashed after about two seconds. The 0.3.6 version was from just before it became the latest version yesterday. Meanwhile I decided to load 0.3.4 on my laptop "c". It did not work because the program will only work on a 64 bit machine. Then I tried to load it on my shack computer "d". same results But, I did not know that the program would not work on a 32 bit machine. For those of you who post on GitHub, please identify your posting with the fact that it is only for 64 bit machines, or whatever would be appropriate. It took me three days to figure that out. Someone said it on another we site and I finally found it here. Then I tried to load it onto my MacBook Pro "a". There was an installation hint -- "If using binaries on Mac or Linux you have to chmod +x nanovan-saver after unzipping as executable flags get lost with zip." I managed to open a terminal and after two or three tries I think I did the above. However, I don't know what to do now. What I like aboutMac computers is that I get a program with a .dmg file. I execute it and it works. Sometimes I have done the above in a terminal but usually with some help. Could you put a link to a step by step process of making this work? Obfuscated -- that is one of my favorite term. To me it means that the obvious is obscured by all the verbiage. I have been trying to make this work on several platforms for several days without success. Please don't assume that your audience knows and understand how to do these things. I have been a power user of computers for many years. However, I don't under stand code or how to use these procedures. Yes, I am complaining some. Please forgive me. I think you can see why I am so frustrated. Any help would be appreciated. My number one goal would be to have Savor work on this computer "a" in either the Mac side or in Windows 7. Thanks, Joe |

Re: H4 communication Issue
Thanks Roger, did all of that still nothing. In win7 when I plug it in the USB never responds in any way at all like as if nothing ever was connected at all. Nothing in the device manager, and nothing under devices. Tried several times with the drivers, tried cleaning the registry, etc.....then switched to win 10 thinking it would be easy there....no luck.

On the cable, just got a new fancy one from amazon and tried it this morning before sending out my email. I was hopeful that it would work and it did not.......then emailed the group. I have opened the unit and looed to see if there was anything obvious and there was not. Also that way I could make sure the USB-C was fully engaging and it looked like it was. Will open up again, this time with the headset on and look for a bad connector, connection, or solder as you suggest. Thanks again! Phil -----Original Message-----

Re: NanoVNA firmvare, compiled by DiSlord #firmware with MiniSD support

At this moment as you can see i update UI and next release name as v1.0.1
UI fixes still not fully comleted (for see changes need reset config for apply new colors) |

Re: NanoVNA firmvare, compiled by DiSlord #firmware with MiniSD support

@DiSlord - let me ask you kindly following - your H4 branch fw version string comes from
"git describe --tags" which shows always 0.7.1... What would you recommend to put in the VERSION string such I know what fw version has been flashed into my H4? |
