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:
