[KX3 amp]

Can we expect to see the 100w amp before Christmas. I assume it will have bandpass filters? Be about $500?
I believe that will be the only 100w amp for qrp rigs with filtered output so it should be popular with other rigs as well.

Re: [KX3 amp]

>From JA
I'd like to suggest Elecraft to prepare 50W version amp for KX3 since the
max.power allowed for prtable operation is 50W in JA.
Small internal swith to select 100/50W might be nice idea for that.

BTW
Thank you very much Elecraft for accepting direct order from JA.

Hi Atsu,

We could provide a jumper or switch in the KXPA100 to limit power to
50 watts.

Thanks for the suggestion.

Is there an approximate weight on the KXPA100 PA ?

Re: [KX3 amp] 100/50

In reply to this post by JE1TRV

Wayne, I like the idea; albeit for different reasons. I began
operating QRP on all my rigs for 4 special reasons.... My Hamlets - my
four children that are all licensed and formed their own club WK1RK. In
fact, my youngest son is now studying for an Extra upgrade (and he is 12
and the Net Control for their VOIP net).

I never run more than 20w HF or VHF because most of my antennas are
close enough that any higher would be problematic. In the Van as well. I
would love a switch or jumper on the amp to set a max power. Will the
Amp be linear or simply a flat fixed output? If the Later, then a three
position switch of 20w, 50w, 100w would be useful as well in the long
run. Those are three power settings that actually are steps up.

I was not sure about this until I saw the post from JA but agree (even
if for different reasons). A switch would be best for me as I could flip
the switch based upon whether I have the kids with me or not.

As the AMP is a but down the road I hope this is something worth
considering and is early enough to be considered in the developement.

Anyone else find this useful?

Somewhere between 1 pound and 50 pounds.
Patience - we will have the details later. It will not alter the gas

Absolutely. IMHO, a 3 position switch or jumper at the
power levels below would be ideal.

Re: [KX3 amp] 100/50

*FW switchable might work better?

Would hate to have to run around back of the motorhome to crank the power
up...especially if I am moving art the time...could be problematical?

That would be good, since the intermediate license in the UK limits ops to 50w too. A great way to buy a good rig for the future and remove the link when they get the full license.

Hi Atsu, Do you get 41 minute response from the chief designer at your local radio manufacturers? !!!

No committees, no design review, no marketing studies, no cost/benefit analysis, just customer satisfaction.
Or maybe Wayne IS all the above - he just did it in the 41 minutes.

[KX3 amp] 100/50

Hello Rick,

To be fair, if the sales volume of elecraft products is in line with those major Japanese ham radio manufacturers, it will be very difficult for both Wayne and Eric to maintain the existing response time.

Of course, as a customer, I appreciate very much the service level offered by Elecraft.

TNX & 73,

Johnny VR2XMC

I'm not worried. WHEN, (not IF) Elecraft sales volume exceeds the JA manufacturers,
Wayne and Eric will have trained people to take care of customers. They don't do
everything themselves today. They have great employees who work the same way they do.
It's part of their culture, it's been that way from the start.

But that day might already be here Johnny. How does the sales volume of KPA500s compare
with that of competing solid state amps? You think the production line of JA amps just
"might" have been scaled back in the past 6 months ? !

[KX3 amp] 100/50

Hello Rick,

May be a bit off-topic here.

I have no idea of how KPA500 sales volume compared with other competitors. My choice of KPA500 is due to its ability of being portable and I don't need full 1kw in my apartment operation condition.

My original intention is to get a SPE-1ka expert where is only slightly less than US$4000 here in VR2. I consider SPE-1Ka is very value for money in my prospective (or in terms of $/watt) and also fulfill the ability to be portable. However, I am using hamstick in a high rise apartment so that it is no way to operate full 1kw. Therefore, I drop idea of SPE-1ka. Bearing in mind, the total cost of Elecraft amplifier should be KPA500 + KAT500.

For similar reason, I sold my Icom ICPW-1 which was a strong work horse. The sales proceed of my PW1 will be very much enough for me to buy any 500w linear amplifier.

The strengthen of JPY does give hard hit to Japanese manufacturer. In terms of US$, street price of ICPW1 has been increased from US$3,900 to US$5,000 solely due to the rise of JPY. Bearing in mind, ICPW1 delivers full 1kw RTTY.

Business culture of US and Japanese is different. Both cultures have its own successful history depending on when and where. In the early days of my business school in the universities, Just-in-time (no stock of spare parts) was given high regard. Toyota has been a succesful example of Just-in-time. However, after the tsunami last year, most Japanese manufacturers exactly died on the hands of Just-in-time.

Hong Kong is some how a link between western and eastern culture. We are hugely influenced by the British in terms of western ideas and at the same time have our own eastern values. We are lucky enough to learn the good / bad of both cultures. The composition of my radio shack fully reflect this. I have the big ICOMs as station radios. K3 is for portable and QRV to outline islands - the smallest radio with true dual receivers. The forthcoming KX3 will be used as a man pack radio. Lastly, I have a US$30 Chinese H/T for casual use.

Under digital mode, NUE-PSK modem is my choice for PSK31. SCS pactor 3 modem is for airmail and winlink.

TNX & 73,

Johnny VR2XMC

I'm not worried. WHEN, (not IF) Elecraft sales volume exceeds the JA manufacturers,
Wayne and Eric will have trained people to take care of customers. They don't do
everything themselves today. They have great employees who work the same way they do.
It's part of their culture, it's been that way from the start.

But that day might already be here Johnny. How does the sales volume of KPA500s compare
with that of competing solid state amps? You think the production line of JA amps just
"might" have been scaled back in the past 6 months ? !
