[hpsdr] Yaesu Amp

[Tom Cathey]

Steve,
 
I'm building one up right now, except with the 1000D PA unit and LP filters.
Here's a thread with pictures of an FT-1000D PA unit and LP filters I will
be using with the HPSDR.  The only thing I am still missing is the LP board
control unit that takes signals from Penny to the LP filters to switch
bands.  The board got lost in the US mail and I'm currently dead in the
water on that part.
 
 
Other than that, the unit should be ready to fire up soon.  
 
 
BTW, I've found the 1000D 200w PA unit to be VERY clean at about 40W pep
out. (-40db 3rd)    At 200W, it is down around -32db.   I only need about
40W drive for the tube amp, so it will complement Penny's clean output.
(Penny is much cleaner, however)   I have no info on the 100w  Mark V Yaesu
PA.
 
The amplifier unit will have full swr and current protection using an
outboard shutdown board.  10mW in  = 200w pep out.

Has anyone taken the amp and filters from a Yaesu and used them with HPSDR
(Penelope/Mercury/Metis)? I searched the archives, but didn't get any hits.

 

I have an old FT1K MK5 (200 watt) in storage just begging to be used for
something useful.
