The Radio Shop:
In the following pic you can see the path of the receiver through the "front end" of the radio. Also shown in dark green is the local and fundamental frequency paths to the mixers.

Your welcome,I have a ques.does the tx run thru the center pin of coax or the shield?
I kno its a stupid one but on the diagram it looks like the rx is coming thru the center conductor ???

Good question,
The receive and transmit go through the center conductor. The receive is picked off through block labeled L.P.F
Here is another attachement that shows the receive, trans mit paths, along with the frequency and audio paths.
I will complete the other half of the schematic shortly
