I would like to thank Don Wilhelm W3FPR for his suggestions. I put the antenna center connector across the junction of D6 and D7. The audio increased considerably with what sounded like atmospheric noise but there were no signals and the VFO readings changed but did not tune in anything. I connected the probe to TP1 and entered CAL FCTR and got a 0000 display. I connected the DMM to the left side of R30 and the reading was 8.25 V regardless of band and frequency. I checked the BFO at TP2 and the high and low readings were correct with the right amount of separation. I have removed the the KDSP2 and jumpered the headers so I can get to the PLL part of the board. Now I am going to have to build the RF probe before I can go any further. Thanks again Don.
