I have had a similar problem with one of my analyzers.? It only likes relatively small memory cards.? ?Got any 1 or 2 gigs? You really don't need anything as big as a 32 gig. Kent WA5VJB

Aparently most newer cards do not work. I have tryed 11 different manufacturers SD 32 Gig cards and none of them work. Aparently You need one of the older style SD cards. I found 2 older 16 Gig cards,

CORRECTION: that was a VNA-64 (not 65) sorry. Mike C.

Hi John, FWIW, I purchased 2 units (tinySA and VNA-65) both from R&L and I am a happy camper. (i.e. no problems, your mileage may vary) Mike C

Thank you - you've done a lot of work with the nanoVNA, it looks very interesting - Mark/K4LFL

I have been happy with my SAA-2N from R&L. 73, DOn N2VGU

My application is something like a bracelet antenna. Not spying. Lol. But as to the "short" calibration of the coil. According to an ST rep: "The idea is to calibrate away the characteristics of the

John, I have been entirely satisfied with the two SAA-2N units I bought from R & L. --John Gord

Can you see more info on my site -- Gyula HA3HZ ( http://ha3hz.hu )

I bought my Nanovna H4 from R&L and with the exception of not getting the "open" calibration standard it has worked fine.I have heard that you don't really need that calibration standard but they are

People are just mentioning that the VNA is transmitting very small amounts of power on that wire as if it was an antenna, and thus it will start behaving like one. You don't really have a choice if it

Many thanks David. Your link does take me to a V2 group with posting this month although not on the subject I seek. Some group identity confusion. I was already subscribed to a V2 group (groups.io)

There was a post in the V2 group on 2022-Jun-16, so you may want to check that... /g/NanoVNAV2/message/3411 David GM8ARV -- SatSignal Software - Quality software for you Web:

I am totally new to Nano VNA and earning. Was planning to purchase a NanoVNASAA2N from R & L Electronics. Then I discovered that Tindie seems to be the "official" source of the V2's etc. Would

.. Here are 2 pictures from my measurements - one with grounded nanovna during the measurement with a length of stranded wire put into S11, the second with nanovna not grounded. You may see the

Yes, nanovna will show you the resonance peaks in form of max |Z| in case of EFHW antenna pretty well (see the picture in my previous post). I did it many times with various EFHW antennas. Simply put

I thought this was a fair question, so I tried it. I laid out about 8 ft of stranded wire about 16-18 AWG. Poked a few strands into a female SMA coupling. Connected that to about 4' of RG-316, which

Mark, Great news! The person that put that document together did a phenomenal job.I think the name "beginners Guide" may deter many who are in fact very knowledgeable?to perhaps assume the document

Your antenna works because the radio metal case, power cord and the shield of any accessories connected to the radio are acting as a counterpoise. You don't have a free space antenna setup. Mike N2MS

Measuring Return Loss means you are sending power to something and measuring the power returning back to the source. Then the calculation can be made. You can't calculate RL to a single wire just
