Yes! The "big" switch, thereby demonstrating flexibility in matters of 
output power. "A foolish consistency is the hobgoblin of small minds" as 
Emerson would say. (I assume at least an upright knife-switch, bolted to 
the floor and connected to bank of van de graaff generators...)


Have a good day.

that rare DX station peeks over the horizon for a once-in-a-lifetime
fleeting moment, seconds count and size really does matter. At these
times, we flip the big switch.

Terry and All,

Your view is shared by a lot of us, but not everyone.  The hard core QRO folks are having a 
euphoric experience right now.  Christmas in April ! Well, I think it is great that their wishes 
seem to have been granted.  I suppose if all the stars lined up just right I could be one of them! 
However, like you, I have some difficulty justifying the cost/benefit. Also, I'd be hard pressed to 
make something like that work at this location. So, I don't need to spend a lot of time lamenting 
not having a bigger amp, and it really wouldn't help me "hear" any better.  It is not 
insignificant that it will cost almost 3 times as much to gain only slightly more than 1 S unit.  
Then, when you factor in the question of "how often do I really need that?", the 
justification becomes even more obscure to me.  One thing is for sure, a lot of electricians just 
got more work!  I strongly suspect not everyone is 220 V ready!

I think it is rather interesting how Elecraft has come to this point.  Many years ago, I saw first hand (at Pacificon) 
the two amps they had as prototypes, one of which was "legal limit".  Then they went silent for a good while 
before coming out with just the 500 watt model.  I thought that was a very astute decision, but probably because it 
suited me perfectly.  I can only guess at how this strategy evolved.  I actually expected this bigger amp to come out 
earlier, but I do not second guess Elecraft on their decision making.  They seem to be pretty capable of making very 
good decisions without my advice!!!  The groundswell of interest in a bigger amp has been hard to ignore, and obviously 
they didn't ignore it!  Then Eric tickles everyone's chain recently by asking "what would you want to see in a big 
amp?"!  That doesn't even meet the definition of "foreshadowing"!  It was more like "check your 
bank accounts folks!"

Elecraft has nearly mastered the art of stimulating expectations.  Have you 
noticed that, when something clearly doesn't fit their plans, they will quash 
the conversation, but when it isn't so far fetched the silence is deafening?  I 
think they have as much fun doing this as they do designing the stuff!  I can 
almost hear them giggling as they put together that cropped photo of the new 
amp!  Anyway, put on your crash helmets and protective gear at their booths in 
Visalia and Dayton.  It's going to be crowded!

O.K.  Now what do we talk about???

Dave W7AQK

From: Terry Brown 


If the new Elecraft amp is indeed 1500 watts it might be worth considering that 
going from 500 to 1500 watts is only about 4.5 Db or less than 1 S-unit in 
signal strength.  If I owned the KPA 500 it would be a hard sell to get me to 
move to ANY 1500 watt amp.

Respectfully,

Terry, N7TB

Re: [Elecraft] KPA 500 vs New 1500 watt amp

2017-04-21 Thread Michael Cozzi 


Hi all,

	I have such a hard time following this conversation because... to me 
none of the debate matters.


	What matters is that Elecraft, a company that is greatly respected, has 
introduced a fabulous product.


	They are such a good company. And while I'll not be upgrading my 
KPA500/KAT500, I've got to give them credit for taking the worry and 
frustration out of buying equipment because the quality is so high.


	Maybe when I was building my station I would have gone for the KPA1500. 
Maybe.


Really- any 1500w amp is beyond what I need for my purposes.

	But you've got to hand it to Elecraft. Go ahead and hit the ball out of 
the park: Every. Single. Time.


And my praise includes the little bit of support I needed.

	So even if you do not want this amp... just celebrate it anyway. 
There's not many companies like Elecraft in or out of ham radio.

plus costs for 30A 240v twist lock connectors/outlets & 60A utility box with 
three breakers.  I see 2v drop on 240vac under load of the 8877.

KPA1500 nice design using separate 50v switching PS.  Many new ham radio PA's 
coming out that use 50v so this could be multi-use PS.  I would like a 2m 1500w 
sspa using LDMOS to replace the 8877 & HVPS.  Not looking for that from 
Elecraft (I will probably buy a kit from W6PQL).

PS: if I were in market for HF QRO the KPA1500 would be my choice!  I finally 
upgraded to the KXPA100+KXAT100 for my HF/6m needs (driven by either KX3 or 
K3/10).

Re: [Elecraft] KPA 500 vs New 1500 watt amp

2017-04-21 Thread Edward R Cole 

Congrats to all who have wanted a KPA1500 (I'm not currently a prospect):

Interesting misconceptions already "flying"
"1500w cost three times 500w"

KPA1500 with internal tuner = $5995
KPA500+KAT500 = $2684.95*
5995/2684.95 = 2.23
*April special price

Power requirement 240vac @ 20A = 4800w
But likely the amp will draw 1500w/0.7 = 2143w (or so) plus maybe 
200-300w for solid-state control ckts

call it 2400w in round numbers or 240v @ 10A (just my guess)

My 6m 1000w PA draws 50A @ 50v = 2500w (40% eff. with 16 transistors)
My 2m-8877 1400w PA draws 750ma @ 3700v = 2775w (50% eff. but with 
tired old tube)


20A is a convenient 240v value since breakers for that are readily 
available;  I ran about 45-feet of No. 8 wiring to bring 240vac to my 
shack where I use a 60A breaker box with a 20A breaker (only tripped 
a couple times in several years useage - HV flashover & HV 
transformer failure).


I ran my own 240v run as I tired of waiting five months for the $700 
Electrician to show up.  I think the 4 cond. No. 8 cable ran about 
$1.50/foot plus costs for 30A 240v twist lock connectors/outlets & 
60A utility box with three breakers.  I see 2v drop on 240vac under 
load of the 8877.


KPA1500 nice design using separate 50v switching PS.  Many new ham 
radio PA's coming out that use 50v so this could be multi-use PS.  I 
would like a 2m 1500w sspa using LDMOS to replace the 8877 & 
HVPS.  Not looking for that from Elecraft (I will probably buy a kit 
from W6PQL).


PS: if I were in market for HF QRO the KPA1500 would be my choice!  I 
finally upgraded to the KXPA100+KXAT100 for my HF/6m needs (driven by 
either KX3 or K3/10).

Hi Fred,

$5995, complete with internal ATU and external, lightweight switching power 
supply. See:

I might point out that only Elecraft offers a legal-limit amp with a

Our philosophy at Elecraft is to cover both ends of the spectrum. Figuratively 
speaking.

When the bands are open, the birds are singing, and the sun is shining, you’ll 
find us outdoors using a hand-held KX2 at 10 watts with a whip. But late at 
night, when propagation is in the tank and that rare DX station peeks over the

Re: [Elecraft] KPA 500 vs New 1500 watt amp

2017-04-21 Thread Rick WA6NHC 
No it is not insignificant but the price point is very acceptable if you 
look at other similar amps, even better when you factor in the tuner 
(repackaged KAT500?  the range limits are similar). Then add in the 
superior level of support that you'll get compared to most other 
companies (and they're 'local' for US hams, another bonus).  I've 
already asked to be put on the notify list and I'll likely put the order 
in at the first possible moment.  Minor bonus for me is that I won't 
have to pay CA taxes by the time it comes out (I'm leaving CA) saving me 
almost 10%.


When you need it, you need it.  You can always turn a KPA1500 down, but 
when you're at max on a KPA500 and it isn't enough, it's over.  If 
you're a DX'er, that's a high frustration point because almost all 
others striving for the rare one will be running full legal (or more).  
Another 4.5 db may make that difference. Technique can only take you so 
far, just as having power without technique can only take you so far.  
Good on both counts means a higher success rate.


At some point in 'serious' ham life, the typical shack will be wired for 
220-240V since it makes so many things simpler; that is a one time 
expense.  Either through fortune or planning, all the components I've 
put up over the last ten years are capable of at least legal limit 
(chokes, cables, wires etc) so I'm prepositioned for full QRO.


I smile when I see Wayne mention overhead... the devices are rated well 
above 1500 watts (each) and simple math says that 240V @ 20 A is a LOT 
of overhead space, even considering power supply efficiency losses 
(which are small with good design).  While I would have preferred seeing 
more antenna ports (since I am used to the KAT500), it's not a deal 
killer (my move means new antennas, I'll make them more resonant than my 
current station).  I'll probably do something along the lines that the 
K3 ant 1 will be for HF and the second antenna port will be used for the 
KPA500 on 6M, which is more than enough for meteor scatter or openings.  
The KPA1500 port one will be 160/80M and port two for 40-10M (still 
power limited on 60M, barefoot might be too much).  That part is simple 
stuff to figure out to be determined later.


I'm not concerned about the 15 db FCC limit with a K3 (life is too short 
for QRP) because at each level, NONE of the amps in the K line chain are 
being pushed to max, making IMD inherently MUCH lower.  If at some point 
Elecraft can add/bless an external device for feedback and 
pre-distortion for the K3(s); that's even better.  But in fairness, if 
one is using a QRP rig, being able to jump to legal limit in one step is 
a big deal.


The ONE feature that makes it for me is that ALL my station elements 
will stay integrated; not so if another brand amp is used.  This is HUGE 
since I operate the station remotely when I'm on the road.  Everything 
'just works'; the operator isn't concerned about any aspect, just click 
on the DX cluster spot (or net frequency) and everything is done except 
making the contact. For the newer ops, it didn't used to be that way, 
trust me, the integrated ability IS a BIG DEAL.


Well done Elecraft!  It's what we've come to expect and that is why 
we're faithful.  Please pass the Kool Aid.  ;-)

If the new Elecraft amp is indeed 1500 watts it might be worth considering
that going from 500 to 1500 watts is only about 4.5 Db or less than 1 S-unit
in signal strength.  If I owned the KPA 500 it would be a hard sell to get

Re: [Elecraft] KPA 500 vs New 1500 watt amp

2017-04-21 Thread w7aqk 

Terry and All,

Your view is shared by a lot of us, but not everyone.  The hard core QRO 
folks are having a euphoric experience right now.  Christmas in April ! 
Well, I think it is great that their wishes seem to have been granted.  I 
suppose if all the stars lined up just right I could be one of them! 
However, like you, I have some difficulty justifying the cost/benefit. 
Also, I'd be hard pressed to make something like that work at this location. 
So, I don't need to spend a lot of time lamenting not having a bigger amp, 
and it really wouldn't help me "hear" any better.  It is not insignificant 
that it will cost almost 3 times as much to gain only slightly more than 1 S 
unit.  Then, when you factor in the question of "how often do I really need 
that?", the justification becomes even more obscure to me.  One thing is for 
sure, a lot of electricians just got more work!  I strongly suspect not 
everyone is 220 V ready!


I think it is rather interesting how Elecraft has come to this point.  Many 
years ago, I saw first hand (at Pacificon) the two amps they had as 
prototypes, one of which was "legal limit".  Then they went silent for a 
good while before coming out with just the 500 watt model.  I thought that 
was a very astute decision, but probably because it suited me perfectly.  I 
can only guess at how this strategy evolved.  I actually expected this 
bigger amp to come out earlier, but I do not second guess Elecraft on their 
decision making.  They seem to be pretty capable of making very good 
decisions without my advice!!!  The groundswell of interest in a bigger amp 
has been hard to ignore, and obviously they didn't ignore it!  Then Eric 
tickles everyone's chain recently by asking "what would you want to see in a 
big amp?"!  That doesn't even meet the definition of "foreshadowing"!  It 
was more like "check your bank accounts folks!"


Elecraft has nearly mastered the art of stimulating expectations.  Have you 
noticed that, when something clearly doesn't fit their plans, they will 
quash the conversation, but when it isn't so far fetched the silence is 
deafening?  I think they have as much fun doing this as they do designing 
the stuff!  I can almost hear them giggling as they put together that 
cropped photo of the new amp!  Anyway, put on your crash helmets and 
protective gear at their booths in Visalia and Dayton.  It's going to be 
crowded!


O.K.  Now what do we talk about???

2017-04-20 Thread Scott Manthe 
One S-unit in a pile-up or on a noisy band can be a big deal. If all you 
do is rag chew in low noise environments then maybe you wouldn't notice. 
In the noise on the low bands or if you're trying to break a pile up, 
that 4.5 dB means you're a lot louder than someone else. Whether that is 
worth the price is up to the op to decide, but the myth that the 1KW 
difference in power makes no difference is just that, a myth.
