Re: VHF MTR2000 Poor Receive Performance

 

Jared,

Can you put a 50 ohm load on the directional coupler and show us what the return loss looks like for it across the same frequency range?

I also went ahead and finally swept the receiver port for return loss and it wasn't pretty at all as shown below.

Closeup on receiver frequency. The little hump at the actual receiver frequency concerns me. Move right or left of the hump and the return loss jumps to -13dBm.

Wide shot from 136MHz-174MHz. Be return loss at 150MHz.
