That is curious. For your reference, I just did an SOLT cal, and left the cable connected from the last through cal step, and get 0dB as expected across the whole trace. I set my frequency span from

Hi Stan, Yes, I am sure that the cables I am using are the same as the ones used to calibrate the VNA. I actually left everything connected after doing the T calibration and then did my measurements.

Group 6 for the first column (Global Express Guaranteed). You need to look all the way over to the right for the FCPIS Price Group (under First Class Mail Package International Service) There it's

Finally got the file...It's attached. Since someone used the example of Thailand earlier, that's Group 10 (for packages), the UK is group 20 For a 8 ounce package - $17.40 for group 10, $18.90 for

Unless the rules have changed, international letters may only contain documents or printed material. Everything else has to go at package rates. Dave N9ZC

Hello You should tell us what you call "over the entire plot". Attached are the results of my measurements on my NanoVNA-F between 1 MHz and 100 MHz with nanovna-saver. The measurement is made on the

Some ideas to consider: Do you have the ports hooked together in the exact same way they were during the thru part of the calibration procedure? I suspect not, because that last thru step of the

No, I totally disagree with your statement. Based on personal experience, every time I had a credit card compromised it was shortly after either some eBay order or some PayPal payment processing. Last

I have a NanoVNA-H: HW version 3.4 with Dislord firmware 1.2.20. I have run the SOLT calibration. When I leave CH0 and CH1 connected together and do an S21 Logmag plot, there is almost -3dB offset

Some users have installed bluetooth adapters, which can give the same isolation result. These use the serial port available inside the nanovna. You could also use a pair of opto-isolators on the

Anything that uses PayPal or other 3rd party reputable card processing is safe. You just have to know if a website is storing the data (uncommon these days) or redirecting to a card processor.

They don't and there is no such thing as real free shipping, it was just included in the price. Shipping is much cheaper from China or the rest of the world. It has to do with agreements between

This is allowed because China is considered a "developing" counry. It is the second largest economy but the GDP per person is lower than developed countries Mike N2MS Mike N2MS

The Chinese Government subsidizes some of there Postal System to a greater extent than the US Gov't does for the USPS. I have ordered $1.24 in parts from China and got free shipping. Not what I would

That's also why I stopped ordering from the US. At least RandL is willing to ship by mail! Many, if not most US companies, refuse to ship by mail, and only give a choice between DHL, UPS and FedEx,

Basic understanding of how card processing works / how prevalent card skimming is. How do you imagine that someone selling something on Ebay gains access to your credit card details?

**Feature creep alert** Could sensitive measurements be easier if Nano VNA had an optical transmitter and companion receiver, or an internal memory to record "screen shot" or measurements on a timer?
