What be the price point for this amp?

What would the average ham pay?  And elecraft needs to make a profit after all 
they aren't a charity.

Ron,

No offense taken - I understand your intentions for the reply. Low antennas are 
a formula for trouble if proper precautions aren't taken. Common sense "should" 
come into play, but we've all seen or heard of examples of hams so focused on 
the antenna itself, they fail to think about what might happen if it falls, 
someone touches it, etc.

And who knows, maybe we'll meet on 30 meter CW - I hang out there quite a bit, 
too!

Ron, you can't teach some people manners. Just like on the air you have to just 
ignore them until they get bored and go away. 
I'm not directing my statement to anyone specific so if you're offended by it

A serious mistake some antenna-limited Hams make is to try to make up for a 
poor antenna near the ground with more power. A situation like Jim brings up 
would likely produce a number of ill effects such as:

1) Producing interference in many nearby pieces of equipment from Hi-Fi systems 
to DVRs, broadcast receivers, etc.

2) If the antenna is not carefully insulated and isolated, animals and people 
can receive very painful RF burns and in the extreme set fires. For those who 
have not experienced a severe RF burn, it instantly creates deep tissue damage 
that is very painful for days or weeks afterward.

3) Short antennas (whips, short wires, etc.) easily produce corona discharges 
at their ends that distorts the transmitted signal and creates broadband Hash 
across the ham bands. 

4) It becomes very difficult to ensure people are not subjected to excessive RF 
exposure if the antenna is not up high and in the clear.

Sorry Jim. What I was referring to were your words "I run my station in a 
HOA/CCR neighborhood and use thin, stealthy wire antennas." 

I'm sure you realize that many Hams in that situation have antennas running 
along fences, even sometimes indoors, or short whips and loops on a balcony. 

It's good that it doesn't apply to you specifically but a great many Hams in an 
HOA/CCR environment must live with a "stealth" antenna systems like those.

Nice work, Ken. On the amps and the cars. I was wondering the same thing 
about "rolling your own". I suggested that doctor who said he could 
build pretty much what he wanted could build the enclosure. He owns an 
electronic lab which builds his stuff and farms the enclosures out to 
another professional. Not sure subcontracting is the Ham Spirit, but 
we're all in this hobby for different reasons.

No for me, thinking about a KXPA100 in the near future, but that will be
plenty for my needs.

 Crowdfunding would also give a good indication on how many KPA1500's

Wayne, if it turns out to be a survey, put me down for a NO vote. I run my 
station in a HOA/CCR neighborhood and use thin, stealthy wire antennas. I’m 
surprised they don’t vaporize as it is with the 500 watts or so coming out of 
my KPA500 - on the rare occasions when I do run QRO!
