Re: Recent NanoVNA-H4 arrival
Hugen said in his mesg that the case has not been changed yet.It's no big deal to cut a slot - only on one half of the housing - you can nibble away with small sidecutters and trim with an exacto knife.that's what i did.

Re: Recent NanoVNA-H4 arrival
Yes, we installed microSD for the latest nanoVNA-H4 after DiSlord completed the microSD migration.
Since we have not completed the modification of the shell mold and have not reserved an installation position for the 32.768kHz crystal, there is no new promotion for the time being.
Later I will modify the shell mold and add a 32.768kHz crystal, and maybe make some new modifications to improve the performance when using harmonics. Thank you for your concern, I will listen to more suggestions.

=====================================================
Bob,
The current version NanoVNA-F as well as the NanoVNA/NanoVNA-H4 with DiSlord's firmware have a 'Power' menu for adjusting the output power. I haven't looked at the actual dBm increment so I don't know if the range would meet your needs.
If you did an SOLT calibration after an attenuator attached to Port1 wouldn't that correct for impedance measurements after the attenuator? To answer my own question I did a SOL calibration after a 6dB attenuator attached to Port1 and then measured a 75 and 100 ohm precision mismatch attached to the output of the attenuator. The measured values were 75 and 100 ohms as expected.

Recent NanoVNA-H4 arrival
Igor Jobim posted on another group that a friend had recently received a NanoVNA-H4 from hugen's shop. He included a photo of the pcb board it it showed that the NanoVNA-H4 his friend received had a sdisk card already intstalled and a slightly higher 2000mA battery than previous version -H4's.
I haven't seen an official announcement by hugen, so I'm not sure if the -H4 with this board is only available by special request or not.

Are there any NanoVNA products, of any version, that have an adjustable Port1 output level? My V2 unit's output is -10dBm and while that's great for working with passive networks, it's a problem for measuring preamps that can't handle that much signal. Yes, I can add a pad at the input of the preamp, but that will affect the SWR and other measurements. A way of reducing the Port1 output level by 0, 10, or 20dB would be very helpful but there doesn't seem to be any way to adjust the stimulus level, only its frequency range.
Perhaps this capability can be added to a future version.

Designing the cases required several nights of hard work and design choices has been done in order to :
- Accommodate a large enough battery and internal stylus fitting
- Have no visible screws on the top and bottom of the case
- Tight fit, stays compact, and easy to assemble
- Leds for battery on the bottom level are visible
Hopping you'll like it.

Thanks Hugen. It is SMA, does the VNA have the same RF characteristics and performance verification as the N type version?.
------------------------------------------------------------------
Ash,
Please note that the N-type also has a 4" display versus the 2.8" display of the SMA version. With a N-to-SMA adapter and SMA SOL standards and cables you get the best of both versions when purchasing the N-type.

I believe you sent your correspondence to Maggie at hugen's on-line

Re: Bluetooth HC5 and nanoVNA-H
Status and enable on the HC05 aren't needed. Only Vcc, Gnd, Rx , and Tx need to be connected. And Rx and Tx are probably labeled from the perspective of the module they are on so probably need to be cross connected Tx on HC05 to Tx on nano and vice versa.
