would you recommend I get?

Hello Hank ... I am pleased to see that you have gotten the answers that you
needed and especially pleased to see a reply from JA7TDO. My experience with
SDR equipment is that it would take a lot of luck, or talent, to make the
Soft66AD2 do something that is beyond his specifications and design. It would
be a daunting task for anyone but a huge task for a person that is not well
experienced in SMT soldering techniques. While I admire your desire to make it
work, I think you would be much better off to sell it and purchase something
that will do what you need. 73 Larry W8ER

then press the tune button or is there a certain way of intering the freq
