Amplifier

I know that at Dayton, Elecraft showed an outboard amplifier to be available at a later date.
I presently have a K3 10 and am wondering id the 10 watts will be enough to kick the new amp and does anybody have an idea how many dollar$ ?
Sorry if this was already covered.

A happy K3 owner Rich KC8HMJ

Yes, it will. You'll likely get more than 100 watts but less than 200
watts output with 10 watts of drive. If you want the full 500+ watts,
then you'll probably need 30W to 40W of drive.

Re: Amplifier

If the SPE does that, which is 17dB gain, then it does not conform to FCC
rules that limit gain to 15dB.

§ 97.317 Standards for certification of external RF power amplifiers.
(a) To receive a grant of certification, the amplifier must:

(1) Satisfy the spurious emission standards of §97.307 (d) or (e) of this
part, as applicable, when the amplifier is operated at the lesser of 1.5 kW
PEP or its full output power and when the amplifier is placed in the
"standby" or "off" positions while connected to the transmitter.

(2) Not be capable of amplifying the input RF power (driving signal) by more
than 15 dB gain. Gain is defined as the ratio of the input RF power to the
output RF power of the amplifier where both power measurements are expressed
in peak envelope power or mean power.

(3) Exhibit no amplification (0 dB gain) between 26 MHz and 28 MHz.

(b) Certification shall be denied when:

(1) The Commission determines the amplifier can be used in services other
than the Amateur Radio Service, or

(2) The amplifier can be easily modified to operate on frequencies between
26 MHz and 28 MHz.

If it has, it hasn't hit the FCC website yet. I just searched.

Re: Amplifier

Why be sorry I'm only wondering... I'd thought that over 15dB of gain
was against the rules. 10W is 40dBm thus +15dBm is 55dBm or a little
over 300Watts.

Lyle's aforementioned 35 watts would be 45dBm +15 gives you 60dBm
which the KPA500 aint a gonna do... Guess the KPA500 is probably only
going to provide around 12dB of gain. While if your measurements are
correct the SPE Expert 1K-FA is giving you 17dB of gain.

Not challenging you I was just wondering.

Re: Amplifier

If we want to split hairs, the 1K-FA is actually advertised as having a
gain of 16dB!! So they are not hiding anything.

The FCC Certified it, so who cares? If you spend all your time trying to
figure out why our government has rules that it routinely ignores, you're
going to drive yourself crazy.

The speed limit on the national highway system is 75mph. Yet the NTSB has
no problem with manufacturers that sell cars that go twice that fast.
Meanwhile, you're surprised that the FCC ignores the 15db gain rule?
Really? Anyone could come up with a thousand examples.

Actually its my work to design and get products through these types of
regulations so I tend to like to know how these different rules work
and how people cope with them. If its not your thing great that's why
there are people like me.

Re: Amplifier

The FCC loves to question the logical and pass others. I have applied for and gotten more than a few experimental licenses that let me do things the FCC would otherwise reject????
Go figure.
