Command to set maximum fundamental SI5351 frequency implemented
|
Edy555 has implemented in his GitHub nanoVNA repository a command to set the threshold for switching to harmonics mode
Command threshold {Frequency in Hz} The default is 300MHz. After changing you can use the save configuration command to permanently store the new value This greatly simplifies testing if your SI5351 has difficult reaching 300MHz and if so, provides a easy workaround I can not test now. Maybe tomorrow |

All working well.
I merged the edy555 additions with my modified scan command and made the build firmware available in the firmware section. Build 0.2.2_1 /g/nanovna-users/files/Firmware/NanoVNA%20firmware%20build%20by%20Erik Usage (assuming your SI5351 supports up to 250MHz): threshold 250000000 saveconfig Remember to do a saveconfig after updating the threshold otherwise the setting will be lost after reset |

Erik,

Your release 0.2.2_1 may have a bug with the 'capture' console command - device locks-up when I try to use capture. Regards, Larry On Saturday, October 5, 2019, 4:01:44 p.m. GMT-4, <erik@...> wrote:

edy555's 0.2.3 release does NOT lock-up with the capture command.

When I run capture from the command prompt, I get a 2 page dump of non-printing output to the terminal, then I get the ch> prompt back I assume it's a binary display buffer dump. The attached file is my teraterm terminal.tty dump:? in console, I hit return twice, then version, then info, then capture, then exit On Monday, October 7, 2019, 11:37:49 a.m. GMT-4, <erik@...> wrote:
@Larry Can you try the edy555 0.2.3 release and see if that also locks up on capture? |
