Received my NanoVNA-H4 today. Looks like a nice device.
I have noticed a problem and just wondering if I am alone...Setting the center frequency to anything above 1Ghz, everything freezes and the only way to do anything turn off and back on again. The results are the same for both the original firmware and the latest Jan 18, 2020 version. Seems ok if start and stop frequencies are selected.

Hi Keith,
Check my review in message number #10012 and Merle W reply in #10024. Merle's confirmation was enough for me to report an issue to hugen on his GitHub page ( ). I also included the quality issue that some members are experiencing with the case opening for the USB-C port.
Setting start and stop frequencies, instead of center frequency and span, as you already found out works fine above 1 GHz. Given hugen's history I know he will quickly release a firmware fix, but this being the Chinese New Year will likely delay his response.
Thanks for confirming the issue and also for confirming that updating to the latest firmware version doesn't correct it.
