Re: Which Amp ?

In reply to this post by Igor Sokolov-2

Hello Igor, I have found that if the SWR creeps thdn the SPE 2KA transmits an excessively wide signal.
Also it generates hash on both 6 and 10 which disimproves reception.
I own this amp.

Joe,

I do not know where the info about SPE being dirty comes from. If it is
that bad, then why FCC had approved it?

If it is that bad, how do I manage to use it with two radio on the same
band and spacing of 3-5 kHz using two antennas separated 200 meters?

Last year we had 2 combo of K3 and SPE 1.3 running in Field day contest.
Both amps where fed from the same generator and we could easily run SSB
and CW on the same band when antennas were separated less then 200
meters. May be other amps are even cleaner but what SPE does is more
then enough to me.

After all, IMD of 1.3K-FA measured by ARRL (Third-order intermodulation
distortion (IMD): 3rd/5th/7th/9th (14 MHz, 1300 W PEP):
–31/–39/–57/–55 dB.) is quite on par with IMD of K3 itself (Third-order
intermodulation distortion (IMD) 3rd/5th/7th/9th order (worst case
band):    HF, –29/–43/–46/–51 dB PEP; ) and pretty close to KPA 500
(Third order intermodulation distortion (IMD): 3rd/5th/7th/9th:
34/53/46/54 dB below    PEP (14 MHz, 500 W PEP output).
