I could send a recording but what is happening is the signal every few seconds jumps 70 Hz. you hear it and see it in the waterfall .
its only a Cristal two 22 pf caps, c25 and c24 to pin 39 and 40 of the U11 ? :oops:
what should I change first ?.

your not going to believe this has happened a few times now !
All I need to do is shut down the HDSDR program and freq problem is fixed !
I also had to recycle the power to the SDR v2 ?

Arthur NS7E all parts arrived now will test transmit !

Do you mean the LO changes by 70Hz every few seconds? I've never heard of anything like that before. In order to help I really need to know your test setup and a more technical description of "freq jumps".
