KPA500/KPA1500 General Coverage?

[Michael Tope]

Hi All,

I have some work colleagues who need to test some HF components with a
few hundred watts of CW power, perhaps a little more depending on what
they find. I think this would mostly be in the 7 to 11 MHz range and
perhaps at the 2nd and third harmonics of this range. Will my KPA500
work for this? How about the KPA1500? What about the rest of the 1.8 to
30 MHz range? Are there any excluded ranges in the coverage of these two
amplifiers?

Thanks,

Mike W4EF......

Mike,

An email to [hidden email] will likely get you the best answer.
It all depends on the filters in each amplifier.

When you get a reply, please share.  I use a KPA500 with a KAT500 on Mars freq from 2-3.5 Mhz, 4-7.5 mhz
and 8.5 to 14Mhz. I have never noticed any problems but I have never checked anything other
does it work and stay within its operational numbers.

"Are there any excluded ranges in the coverage of these two amplifiers?"

Yes.  For the KPA500 see page 16, para 2, of the Owner's Manual.
