[amsat-bb] Re: Pre-amp for IC-910h?

[Jim Sanford]

All:
I neglected to mention in my earlier response that I have successfully 
powered the SP2000 and SP7000 from the IC910H, using the preamp function 
in the radio.  While I'd never use power up the coax for a final 
installation, it sure is nice for Field Day.   My experience is similar 
to Drew's, the SSBs are much lower NF and much higher intermod rejection 
(probably due to the helical filter in part).

Good luck & 73,
Jim
