[Milsurplus] Beam Filter Info

[WA5CAB at cs.com]

Bill,

Doesn't the HQ-150 have Low-Z output?  Depending upon vintage and service, 
that meant either 250 ohm or 500/600 ohm.  Which the Navy filter would 
match.  Hi-Z means 4000 ohms or higher.  Usually 4000 for receivers and 7000/8000 
for audio accessories.
