This is simply 4-way analog splitter. Designed for no-delay PTT switching. From one input to four outputs. You can split PTT signal to four independent devices.
Assembled
This is simply 4-way PTT sequencer, designed for PTT switching from one input to 4 outputs with different (fixed) delay.
This is simple analog 4-way combiner. There is no delay between inputs and output. Each input has its own LED indication and so does the output.
The splitter or combiner is a very useful device. It can provide equal voltages, equal current, or equal power to matched or unmatched loads.
The RX small preamp is very simply low noise preamplifier module with 2SC5551 transistor based on W7IUV design. Use it as high IP preamplifier for RX antennas, buffer amplifier or small driver.
