Try a 17 watt "shoe" combined with an internal power supply in place
of the KAT3/KPA3. 73, Guy

We think it's an amazing little amp, and we hope some of you will, too.

I have a K3/100 and a P3 and use a Ten Tec Centaur amp. The setup works well and is forgiving of my goofs.

I see the KPA500 as an interesting concept and would seriously consider replacing the Centaur. I suspect that the KPA500 will grow in the future to a KPA1500 based upon the advancements in PA transistors. One thing I know for sure is that whatever Wayne puts on the market will be a good value for the $.

I would like to see a power supply to power all the K3/P3/KPA500/etc. in one box. That would make the deal sweeter and enable me to get one more box out from under my desk. Also could we think about a 70cm option for the the 2M module. The satellites are calling.

I wonder how many of you guys have thought about this?

Let's say that Elecraft prices the KPA500 160m to 6m 500 watt solid
state amp with built in power supply at $2,000:

Remember the amp has 6m capability...

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Now let's look at the price of a popular 6m solid state amp:

TE Systems 05612G: $1,388
10-15 W Drive
600 W Output
30 Amps Current Draw (@ 28v)

Astron LS 35A 28v 22A cont, 35A int $345

Investment for 6m 600w amp = $1,733.

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Let's add a 500w solid state HF amp:

SG-500 $1299

Lambda EWS-1500 15V 100A Power supply $399

Investment for 500W 160 - 10m amp = $1,698

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Elecraft KPA500 500w output from 160m through 6m (into one coax?) =
$2000.00.

Desk top space requirement: K3 + KPA500 Amp. Two boxes the same size.

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Comparable 500w HF and 600w 6m output into two coaxes = $1,733 +
$1,698 = $3,431.

Desk top requirement: K3 + TE Systems Amp + Astron Power supply + SG -
500 + Lambda. Four boxes of various sizes.

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Personally, I would rather have one additional box on the desktop at
around $2,000 rather than four extra boxes for $3,431. But then, I'm
just another one of those South Central boys from Texas who may have
missed something ;0)

RM Italy's specifications are an outright fabrication. The MRF-157
is rated for 600 W PEP ... there is no way two of them are going to
make 1500 W CW/RTTY or 1500 W PEP SSB and be clean. Of course RM
Italy's "amplifiers" are notorious IMD generators.

Re: RM Italy BLA 1000 (was - KPA500)

Seems like one of the list regulars ran some test on a RM 200W amp
some months back, the gist of which was that it had horrible IMD at its
rated power (200W) but had typical 13.8V IMD numbers at 100W.

So maybe it's actually a 1000W PEP amp and a some odd hundred watt CW
amp, from a company with a poor reputation and no service for $4 per
watt. What a deal.

I think these amps are better regarded in the EU but they probably
understand how to interpret Italian advertising than we do over here.

Re: RM Italy BLA 1000 (was - KPA500)

Hi Jack

They are not "better regarded"in Europe. They have always been CB amps in the eyes of most hams.

Its mostly new hams from the CB band who like using these horrible amps. RM HF amps have terrible IMD performance especially under dynamic voice conditions.

The positive reviews by well meaning hams are mostly flawed because they use incorrect measurement procedures. I cant see how any amp with -26db pep 3rd IMD figures is something that is acceptable for a high power amp.

The dynamic on air IMD performance of these amps when used with the typically ham transceiver causes terrible splatter. Hams who run these amps are very easy to spot with a SDR receiver.

I like others wont buy a solid state amp until the IMD performance at least matches the better tube amplifiers.

The last thing we need to do as hams is crap in our own nest just because its modern or new!

Re: KPA500 [END OF THREAD]

In reply to this post by Eric Swartz - WA6HHQ

I only just found it!

Now it is out, what is different between the KPA500 and the Tokyo High Power range of amplifiers? Auto tuner? That would be great. The KPA500 is just right for our 400W power limit incidentally - well done there.
