KPA-800 & KPA 1500

Elecraft,
The only AMP that would interest me is something beyond and better than my Alpha 87A. That would be, by definition, a solid state 1500 watt output 160 to 6M amplifier integrated seamlessly with the K3 vie the 15 pin accessory plug. I would like to have the RF deck sitting at my operating position, assemble it myself and have the power supply out of sight. I would buy that amplifier the day it was announced.

Re: KPA-800 & KPA 1500

With the exception of 6m, you have essentially that capability available in
the Tokyo Hy-Power HL-2.5KFX which, thanks to Elecraft's loan of a new K3
for the show (thanks again Eric!), was being demonstrated in the Array
Solutions booth this weekend in Dayton.

In addition, the Tokyo Hy-Power HL-1.5KFX gives you about 1k output on 160
through 10m, along with about 650w output on 6m - also with full integration
with the K3 via the 15 pin ACC connector.

My elephant would look like my 2000A but solid-state - The amp in the
basement and have a Remote Control Unit in the shack. Yes, 160-6M. Don't
care if it is a kit or not. I assume a switching supply like the KPA1500. I
agree about being seamless with the K3.

Re: KPA-800 & KPA 1500

In reply to this post by Bob Naumann W5OV

Yeah, but some of us want 6M too. My 2000A does everything I want from
160-10M - remoted, 1500W on RTTY. But no instant ON. So, it is ON lots of
times when I don't use it - like sunrise on Topband.
I think THP did a great packaging job with the 2.5. If it only had 6M. And
could be remoted. Trying to get the heat out of the shack.

Maybe wishful thinking. But the amp fund has been sitting with money in it
for a few years :-)

Re: KPA-800 & KPA 1500

I think a lot of us are essentially in the same situation: We already have a
good legal-limit amp covering 160 through 10, but we don't have anything
similar for 6 or 2. It takes real commitment to pay essentially the same
amount over again and get just one more band, and building is a lot of work
too. Any manufacturer who can include 6m along with HF has a huge advantage
IMHO, and including 2m would be fantastic. QEX had a design some years ago
that covered both 6 and 2; that really got me interested. Alpha was supposed
to pick it up as part of their product line, but I don't know if it ever
happened. I think there are plenty of areas in the market that haven't
become commoditized.

I have the 1.5FX, indeed an excellent companion to the K3, and the
physical interface is made to measure.

Re: KPA-800 & KPA 1500

In reply to this post by K8RS

This is a great, healthy discussion that can help determine the need for an Elecraft branded amp. If we can't come up with a good set of features that are not met by current products, then perhaps it will be difficult to make the case there should be an Elecraft made amp.

My dream product is a SO2R appliance that does all the RX/TX switching between 2 radios, including bandpass filters and remote antenna selection. 1500 W out, no time limit, RTTY included. Think of a 1500 W version of SPE, plus built-in W3NQN filters and Array Solution's SixPack. 2 inputs, 2 CATs, 2 PTTs, 6 or 10 remotely controlled outputs.

Currently, there is not product that comes even close to such feature set.

Re: KPA-800 & KPA 1500

How about adding a built in tuner in the KPA-800/1500 that would work even
when you ran 100 watts from the K2 or K3 with the amp in standby?

Re: KPA-800 & KPA 1500

In reply to this post by Rudy Bakalov

Rudy,

Just to clarify an apparent misunderstanding with the SPE amp, it is not a
true SO2R device. What I mean is that the second radio can only listen to
whatever antenna is attached to the "SO2R" connector. It does not get access
to the transmit antennas which are connected to any of the 4 transmit
antenna connections. So, while the SPE seems to be a great solution, it is a
compromise at best, although quite clever. You also may want to check with
K6VVA regarding its usefulness and viability in a contest situation.

73,

Bob W5OV

Bob,

I think we are on the same page here; I fully understand the SPE limitations and that's why I say there is no product that fits my dream. I also missed to mention that such SO2R appliance must have the smarts of the microHam products in order the 2x6 matrix to have flexibility in a wide range of environments. So now I would add to the list the functionality of microHam's station master.

That is exactly what is done in SPE 1K-FA amp plus SO2R and automatic
antenna selection. The integration with my K3 is pretty simple too. SPE is
working on 1500W version now and hope to show it at the end of this year or
beginning the next year. 6m is also built in.
