[Elecraft] FS: Elecraft KXPA100 Amp + KXAT100 ATU (NEVER USED!)

[Mike Marusin]

Hey everyone - I bought a KXPA100 Amplifier Kit with the KXAT100 internal
ATU a few years ago and have literally never used it. I have all the
original packaging / manuals and many of the bags with cables, etc have
never even been opened.

It's been sitting in my closet wrapped up and I feel it's time for someone
to benefit from it and actually use it. Selling for $1100 shipped within
the US.

Re: [Elecraft] KXPA100 amp and ATTN switch

[Scott Russell]

Larry, I'm curious why you'd use a homebrew cable instead of using the
Elecraft specific cable KXPACBL? It seems your cable is not performing some
function that the OEM cable provides so it makes it hard for someone to help
with your setup.

Scott, N1SER

Re: [Elecraft] KXPA100 amp and ATTN switch

[Edward R Cole]

Larry,

I have the same combination (KX3 + KXPA100) and my KX3 drives the amp 
fully with output of 5 to 7w.  Takes more drive on 6m.  Each 
band  takes a different drive level.  It seems to me that does not 
track between bands.  I have to manually change the drive level.


But then I am not controlling the KXPA100 with the control line and 
only using PTT.  When mobile I use the RJ45 connection.
Most of the time my KX3 is on either 6m or 2m.  I use my K3 for HF or 
with transverters for VHF+.


I have used the 3-dB attenuator on occasion when I want to drive very 
low (getting 11w output for driving my 6m 1000w amp).  The KX3 or 
K3/10 only give me 8w max on 6m so need the KXPA100 as a driver.

I just connected my new KXPA100 to my KX3 via a home-brew KX3-KXPA100 
Adapter Cable.

Everything works just fine if I have the 3dB attenuator switch set to IN.
I fI set it to OUT/AUTO as described in the manual I end up 
overdriving the amp, meaning the power out is much higher

than set on the KX3.
All the other functions work just fine.
Anyone have any ideas?

Re: [Elecraft] KXPA100 Amp Issue

[Bob N3MNT]

It is also possible to accidentally switch if you hold the ATU button to
long.  If you only have one antenna and want to prevent this, connect to the
KXPA100 utility and you can disable ant 2 so it can not be selected by
accident.

ANT1/ANT2 is a per band setting.  If you have not set the antenna port

Go to each band and set the antenna to whichever antenna is connected, 
then test the behavior by switching from band to band.

If you bought the KXAT100 and KX3 used, the prior owner may have had 
specific antenna selections set per band - if you bought it new, it may 
just be a matter of initializing things.

Re: [Elecraft] KXPA100 AMP and KXAT100 ATU pics and info

[Chuck Shefflette - AA3CS]

I used the OHR connector kits in both my K3s, turning a no-solder kit into a 
very little solder kit. I keep adapters around for those times I don't or can't 
change the UHF connectors to BNC or N, but I swap the UHF anytime I can. BNC 
and N connectors have two additional attributes (beyond being real 50 ohm 
connectors) that are beneficial: they are relatively weatherproof if properly 
assembled, and the ground makes contact before the center conductor.

Just my $0.02

Thanks everyone, for the links, very much appreciated.  I've never looked at
Twitter before (and probably won't again), but very interesting.

 

Maybe at some future date, for those using the K3 on the bench, an adapter
might come along so the KX3 could be attached to the amp/atu?

 BNC can handle roughly the same power as UHF. The max voltage on an Amphenol 
 UHF connector is 600V. The max for BNC is 500V. A Type N connector can handle 
 1500V, so you can see how poor the UHF is for its size.

I think you mean that it will work WITH any generic QRP rig. :)

From what I see in Eric's email, it's the same concept as the KPA500 -- 
although it's specifically integrated with the K3, it works with any rig 
that can give it a keying signal and the right RF drive level. It does 
not need band data, it DETECTS what you're sending it and switches to 
the right band. All you need is the KEY line to put it in TX mode 
(that's an FCC requirement) and give it 4W drive to get 100W out.  
That's 14dB power gain, which, I believe, is also the FCC limit.

Re: [Elecraft] KXPA100 AMP and KXAT100 ATU pics and info

[EricJ]

Just curious why the FCC has a 15 dB limit on power gain on all 
amplifiers. Is it related to the CB issue or is that sufficiently 
addressed in the 0dB gain for 26-28 mhz?


I've been QRP for the last 20 years (except mobile), and anticipating a 
KXP100 for mobile use.

Note that that is true *only* for commercial amplifiers type approved for
sale in the US. US Hams are still allowed to build their own amp with any
amount of gain they choose and can sell a limited number of
not-type-approved amps every year.

Are BNC connectors a possibility?

They are my favorite for anything under 1000 watts on HF too. Of course
there are screw-on adapters for the SO-239 UHF connectors.

Re: [Elecraft] KXPA100 AMP and KXAT100 ATU pics and info

[Rick Dettinger]

Morse Express sells SO-239 to BNC Conversion Kits.  They are just metal plates 
the same size as the SO-239 jacks.  They have the same 4 holes and are punched 
for an included BNC panel jack.
I have used them to convert my non Elecraft QRP kits and OHR watt meter.  But, 
I had thought that BNC was only for QRP power levels.  Elecraft uses SO-239 for 
their 100 watt kits that I have bought.

Re: [Elecraft] KXPA100 AMP and KXAT100 ATU pics and info

[Walter Underwood]

Oak Hills Research sells a similar BNC bulkhead connector that fits in a UHF 
hole.

http://www.ohr.com/parts.htm

BNC can handle roughly the same power as UHF. The max voltage on an Amphenol 
UHF connector is 600V. The max for BNC is 500V. A Type N connector can handle 
1500V, so you can see how poor the UHF is for its size.
