Re: TinySA - Up to 5GHz (Wi-Fi) & $140

No, but if you blame it you should name it - show a picture of your worse little SA! And about which device do you talk actually, how much was it? Very confusing...

Re: TinySA - Up to 5GHz (Wi-Fi) & $140
OK Jim, from now on I shall only wax lyrical about how marvelous and reliable these cheap VNA's and SA's are. I also won't mention that my H4 failed after less than a year (it definitely is a

Re: TinySA - Up to 5GHz (Wi-Fi) & $140
It sounds like you do not have a genuine TinySA or TinySA Ultra. If you buy on eBay or Amazon you stand a good chance of getting junk clones. The TinySA products have overwhelmingly positive user

Yup. I have the same issue. I open VNA View program, connect with that, then close that and VNA Saver will now load, connect and stay alive. Another guy said to pause scans on the nanoVNA before

Re: Nano VNA H4 died.
Hi Roger, I have connected to it and even uploaded the firmware, and all seems to work OK. But when I turn the unit back on, just the normal screen with no sweep happening. Cheers, Peter - VK2AN
