TS-2000X RX Sensitivity Improvement


This modification improves the RX sensitivity of the TS2000.
Full details are described in this document of Woody, AK2F.

An alternative implementation is described in this document by UU2JJ.
For two reasons I decided not to do it like UU2JJ did:
- it requires replacing SMD resistors, rather than bridging them with conventional ones
- it requires more 'unpacking' of the TS2000 and de-mounting of PCB's.

As I lack the appropriate RF measurement equipment, I skipped the suggested SW changes.
No sensitivity measurements are done prior nor after the modification.

Below are just the pictures from the HW modification itself:

Put the TS-2000X up-side-down, open the cover, and flip back the large PCB:

This is where the VHF and UHF pre-amps are located on the center PCB:

VHF modification:
TS-2000X RX improvement PA3GUO

VHF result:
TS-2000X RX improvement PA3GUO

UHF modification:
TS-2000X RX improvement PA3GUO

UHF result:
TS-2000X RX improvement PA3GUO

Finished:
TS-2000X RX improvement PA3GUO
