Subj : NanoVNA To : Tony Langdon From : Richard Menedetter Date : Sun Sep 22 2019 04:41 pm Hi Tony! 22 Sep 2019 18:40, from Tony Langdon -> Richard Menedetter: TL> I bought one recently. Seems to work really well, once calibrated. TL> Need to buy some adapters, so I can connect to my antennas for TL> testing. The 1500 MHz firmware sounds interesting. Must be extremely TL> new. As I use 1.2 GHz, I'm very interested. :) See link and discussion below. But beware that the device is using a maxiumum clock of 300 MHz. It uses first and second harmonisc to reach up to 900 MHz. Its accuracy is getting worse all the time! https://groups.io/g/nanovna-users/topic/nanovna_firmware_extended_to/34141560?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,0,34141560 This is a firmware based on the original Edy555 firmware with some small changes - Upper frequency limit is increased to 1500MHz. Be aware accuracy decreases rapidly above 900MHz - A "scan" console command is added to allow arbitrary sweeps with arbitrary number of points - The stack sizes of the two main threads have been adjusted for increased robustness.(thanks to david mugridge ) https://groups.io/g/nanovna-users/files/NanoVNA%20PC%20Software/TAPR%20VNA/NanoVNA%20with%20scan%20and%201500MHz.zip CU, Ricsi ....
