Yesterday I was trying to tune up the duplexers one can at a time as listed in this Sinclair Youtube Video.

After tuning them my receive is awful and my transmit is somewhat not what it used to be. What could be the reasons?

Here is my last photo on the meter before hooking it up:

Final tune..

Any advice on how to tune these things?

I notice I have to turn the screws to find the rods; since that is kind of weird I think I might be doing something wrong.

Typically hooking the input into the antenna portion of the duplexer and then the output on either side with a dummy load on the other end.

I have a Sinclair Duplexer Model Q2330E.
