Bounty Announcement (Impedance Matching on TX and RX))

Dear All,
We would like to announce a bounty for a modification on LIMESDR-USB.
In the past we measured the S11 performance on the TX1_1 and Rx1_L ports.
See:

We would like to have an Impedance Matching on the TX1_1 and RX1_W.
Here are the requirements:
S11: < -15db
Frequency: 50-90 MHz
RX Sensitivity: Similar or better than the EasyFIX2 modification.
Noise Figure: Similar or better than the EasyFIX2 modification.

Whoever accepts the challence will have all the Glory, He/She can get all the credit and publish the results under their name.
A simulation will not be accepted: Actual implementation is needed.
Our Budget: $200 (Sorry but thats all we can spare).

Is anyone interested?

This seems to be an issue as I am currently encountering the same problem.
