Adding a battery
- My unit did not come with a battery
- Added an SMT mount ST connector to the board
- Added an 850 mAh LiPo battery
- The pinout on the card was backwards from the pinout of the connector at the end of the battery wires
- Removed the pins from the battery wire connector and flipped the pins
- Charging works
- Battery is a bit too thick to screw the back on completely
- Switched to longer standoffs
- Someone else's page (they added an inline connector and wired to the card)
Software
Test Jigs
RF Demo Kit
- AliExpress listing
- Board
- SMA female connectors X6
- 6mm standoffs X4
- M2.5 screw X4 (for standoffs)
- 49 pin machine contact array (7x7)
- (2) 0805 49r9 calibration resistance
- 1 spare)
- Installed 49.9 ohm resistor on upper left SMA
- Installed 0 ohm resistor on upper right SMA (not in kit)
Dual Band Dipole Measurements
- NanoVNA sweeping from 3.5 MHz to 30 MHz
- Following this setup
- Documenting the setup / measurements of SWR on 20M/40M/15M
- Dual band dipole from 3rd floor attic eaves to fence post
- 20 Meter SWR sweep
- 40 Meter SWR sweep
- 15 Meter SWR
