Note how braid is left intact, rather than being formed into a pigtail – this is a better method for PTFE cables.
FT857
VK5DWC PAT installation in FT857W8XDR PAT installed in FT857. I don’t recommend coax for the PAT input connection as the parallel capacitance is high, and could affect tuned transformers.IZ2ZQG’s mounting of PAT in the FT857Detail of the connection points FT857. Black is Ground, left hand red is RxB and right hand red is PAT input. IZ2ZQG.
I note that all three of these users have decided to mount the PAT board on the same screen can. An alternative may be the one to the right in pictures 1 and 2, which has no holes for core adjustment, and gives a much shorter input connection!

Overview of PAT installation in FT847 – PAT70 acting as IF tapDetail of connection at J3009 in FT847 to pick up input signal for the PATPicking up the signal at the mixer (T3023) for 2nd Rx application. Some FT847’s have a shielding can around the mixer.Alternive connection for 2nd Rx where rig has a shield. PCB must be lifted to make this connection. Info due to M0STODL7AOH removed the can and drilled a hole in the side to bring the cable out. PAT in the plastic bag is a PAT-V for 2nd Rx use.
