This circuit should fill the bill. Thanks to WW2R for this design.

Just apply 9 v instead of 12 v! It drives my Yaesu FT-747 brick and  
filters.

My  plans call for using an old Yaesu FT-1000D 200W PA unit with relay  
switched LP Filters as my linear amplifier for Penny.
 
I  would like to switch bands on this low pass filter  assembly using the 
mouse PSDR software band selections along with the  Penny/Mercury band 
selections.
 
Could  someone advise me on the best approach to switch the 9 volt LP 
filter relays,  160, 75, 40, 20, 15 and 10M  using the existing output  
interface?  Or do I need to build an interface? 
 
The  simple alternative is to  just use a rotary band switch and switch  
the L.P filter manually.  I want to explore using the mouse  auto-method first.
 
Thanks.
 
Tom,  K1JJ
