Signal Tracing D6 RF levels

njepsen
I am at the testing stage II step and following the signal tracing steps in an effort to locate low rx sensitivity. I have 140mv on the antanna ( as per pg 11 Appendix E) but can only get 4mv at D6. The book says it should be about 86mv. I have 100mv at both sides of C6, but only 4mv at D6. Any suggestions welcome.

L1 & L2 peak nicely, the cap values are correct.  *R( 7.6v dc) is present at C4, proving that there are no shorts to gnd, and relay K18 are OK. Lifting D6 and D7 doesnt alter the 4mv. R5 is a 2k7.
