Hi Bert thanks for the hardware information.
However .... I don't see some of the resistors mentioned on the only
schematic of the nanoVNA (12/29/16 @11:31AM) I can find.
I was interested to see which resistors needed changing before delving
inside. Is there an (earlier/later) schematic somewhere?

Hi Dave,
First You must upgrade the hardware of Your device.
- remove R29, R30 and R31
- replace R13 by 0 Ohm
- replace R9 by 200 Ohm
- replace R24 by 91 Ohm
- replace R22, R23 by 49.9 Ohm
- replace R25 by 11 Ohm
In order to use the full frequency range (10 kHz to 1500 MHz) You must
update Your Firmware.
Regards Bert
