VHF Trans/Reflect Set

Post by Sam » Tue Nov 22, 2011 12:58 pm

Hi All,

A board labeled VHF Trans/Reflect Set was included in one of the PCB group buys. I have discovered two errors. First, there is provision on the board for ESD diode D1 on the T/R input, but that diode is missing from the schematic. ESD5V0D3 would work. Also, D2, the relay protection diode, is not properly placed on the schematic or board. It should be across the relay coil (pointing to + terminal), or pointing from the - coil terminal to the +10 supply.



I know of one person currently building this board. If anyone else has built it, let me know how it worked out.
