Slave transmitter

With the help of SM7GYT Gert we built  a slave transmitter

That send to SK7RJL on 432,725 MHz.

Built on 2 Motorola Mc Micro

With the two filters used to link along the railway

And a little simple logic.

Output 2 Watts.

Sensitivity -114 dBm after the filter is equivalent to about 0.9 uV.

Works very good.
