Hello Herb and others, We already have official support at the /g/NanoVNA-V2/ group, user *nanov2support *from the HCXQS group. Cheers. *73 de Luís, CT2FZI* *QRV @ 145.300 MHz |

Hi Gabriel, I can only say they respond in a very correct way to emails. I asked if I could buy another one and get it sent by an express service like DHL or Fedex. Their answer: The typical total

Ok, it not i2c bus Now try not use 96kHz DAC, revert back to 48kHz

Ok, I installed firmware 0.8.4.3 "stability test variant" with config clear. This did not resolve the problem but I made an observation. The effective error increases with each sweep iteration,

Yes. Sample attached. I adjusted threshold from 295-305MHz by 1MHz with no change. Then, as noted above, I swept ranges below 300MHz (no harmonics) with similar results. Peter

Personally, I prefer the -F as it has a metal case better at keeping ambient RF fields out of the electronics of the instrument. The small screen of the original is spiff, but just a bit too small for

When you were doing prototype runs what was the price of JLPCB assembly service per board? For ham clubs getting a few boards and soldering a few parts by hand is maybe an interesting proposition. How

OK. It is properly normalized. Personally, I'd believe the NANOVNA. Dave - W?LEV -- *Dave - W?LEV* *Just Let Darwin Work* *Just Think*

Yes, Ive done the required calibration. Problem is there are times the needle wont meet the calibration point. Im sure the settings were correct. There are 3 separate settings for 5w, 20w and 200w. I

Question I see there's 3 of these "VNAs", one has small screen about 2.5 inches, another is VNA-4, and another VNA-F, Are the all the same or is there a big difference in what they do?Sent via the

Thank you for the responses! The issue occurs standalone. I only used NanoVNASaver to get the S1 images for my post in this forum. It is version 0.2.2. You are correct. That is the original version in

I will do it right away. Did not do it before, as I didn't want to hijack anything official... *73 de Luís, CT2FZI* *QRV @ 145.300 MHz | **CQ0VMST (VHF REP Monsanto)* <http://goog_717545661>

Did you see my suggestion in message #12834 about adding a CONFIG-THRESHOLD menu to allow changing the threshold frequency with using a computer terminal? Yes i see but this value need chane once and
