Hi Everyone,
So I am aligning a Grant XL (PB-208AD). I just got my replacement freq counter (HP 5335A) from the alignment shop and it seems like it is working perfectly. I have aligned a radio and it went well. I am now on to the Grant XL and hmmm. In the frequency alignment process I am supposed to connect the freq counter to TP-5 and align USB to 7.8015 and LSB to 7.7985 +/- 5Hz. The freq counter is not locking onto a stable reading for me to align it. It sees 7.*** but its not a sable reading. I feel like it is just below the input sensitivity level of the counter. Have you experienced this? Is there a way around this? I am thinking I may need a small input amp to help this out in the future.

Thanks!!
