Hi Yaesu lovers , I'm looking ( searching ) for the data sheets or the specs of the monolithic filter 9M20A ( FT7-B) and the crystal filter XF90A . My goal is to rebuild a FT7B and simulate the whole transceiver in LTSpice . ( replacing the 3SK51 with BF961/981 and so slidly adapt the circuits )
Any help is mostly welcome .
