The circuit it will not work as a SWR meter, because there is no directivity in the coupler used.
Thanks for the reply. It just goes to show that people place bad /non-working schematics on the internet.....why they would waste their time I will never understand. I have everything for the schematic you told me to look at. The 10pf trimmer is used for fine tuning? Anything else you can tell me about this circuit before I build it? Usage/design etc....
Thanks
Looks like a bridge circuit to me, which could be used to measure the load impedance.

yup exactly and you wont measure SWR with a bridge !
The configuration is not a bridge.
