Linear thoughts

[Elecraft mailing list]

Just as an FYI,

Expert Linears Dan Tassell KC5PCB makes up a custom plug-and-play cable for the K3/SPE, so interfacing is really not a problem.

At Orlando the introductory price for the Genius was $6999.00 and they were taking orders for. I think, June delivery.  They just received the FCC type acceptance a few days before.
I would assume that the SPE amps all integrate with the K3 in a similar fashion.  When I used the SPE 2K in CQWW CW it was like having a 1.5K K3..just hummed along all weekend.

I think that the ship has sailed with respect to Elecraft bringing a legal limit SS amp to market.

There are a growing number of lightweight legal limit amps already on the market.  The FlexRadio Power Genius looks especially promising:
http://www.flexradio.com/amateur-products/powergenius-xl/

It only weighs 33 pounds.  I saw it in operation at the Orlando HamCation and it looked very impressive operating all weekend into a dummy load at a conservative 1.5 kw output.

SPE also just announced a 1.5 kw amp..something I'm surprised they did given that they already have a 1 kw, 1.3 kw, and a 2kw amp on the market.  I know of several people that have the 1 kw amp and use it with their K3 radios and they love them.  I've used the big SPE amp in CQWW CW and it worked flawlessly all weekend without a hiccup.

Dan is a great guy, but all that’s really needed for the K3 is a simple
cable, very easy to construct yourself.....SPE even provides the
connectors....

NO special cable is required. All you need is the RCA - RCA keying cable
between the K3 and the amp and coax for RF. That's all I'm using with an
SPE-1K. The SPE senses the frequency of RF drive and switches. It also
recalls previous tunings of the built-in antenna tuner.

I have a 2K-FA and as Jim mentions, you can use the bare basic RCA cable to
key it etc...  however, depending on your setup, it's certainly easy to
make up some custom cables  Get some CAT5 stranded cable and read the
manuals (RTFM).  The CAT control input on all the SPE amps have the same
pinout and the amplifiers ship with the DB15 connectors and hoods.  It's
not rocket science to make a cable which is custom to your needs.  Plus,
you can take advantage of the key out on the K3 acc port and have the SPE
amp control TX-INH if you want etc...  making a cable up is probably easy
enough that a typical cave man could do it, if he/she has bare bones
soldering station etc...

Download the manuals and spend some time studying up on what you can do and
how to interface it with your K3... the last time I checked it's still
legal to use a soldering iron and some wire strippers.  If you order up
cables, you will get what you get and there are several different things to
consider when interfacing your rig with an SPE amp.  Why not get what you
want for cheap and learn something long the way rather than paying for some
pre made cables in this case. ;)  And yes, there are cases where we get
older and have a hard time with tiny connectors etc... and our eyes get
bad, so I get that.  Get a ham buddy to help you out.

Anyway... another thread lives on about Elecraft building a KW amp etc...
the Ever-Ready bunny keeps going and going and returning. :)
