KPA100

wsm-3
If I add the KPA100 to my K2 and decide I want to operate qrp, is
there a way to bypass the kpa100, or do you just turn down the
power knob? It will be a long time before I fully understand the K2.
Thanks

RE: KPA100

Gregg R. Lengling
Just power the unit from the lower coaxial power jack and you have a QRP
rig.  If you turn the power down you'll get the same thing but you'll have
higher current draw due to the idling current and circuits in the amp.

You can QRP two ways:

1) Turn the power down (the obvious). The POWER control runs from zero to
100+ watts. The KPA100 is switched out of the transmit path below 10 watts.

2) You can switch the KPA100 amplifier off using the MENU command. Now the
rig behaves exactly like it did without the KPA100 except that you have the
advantage of the SWR bridge and SWR display on the K2 and, of course, the
SO239 connector on the KPA100 remains the normal antenna connector.

With the KPA100 off the total K2 current drain is 8 to 10% higher due to the
circuits in the KPA100 that run even in standby. That's normally of no
concern unless you're running from a limited battery supply. People
operating portable in the field may simply swap the covers, removing the
KPA100 and putting the "QRP" top back on with its built in antenna tuner and
battery supply.

Strange Reflector Behavior

Ron D'Eau Claire-2
I just scrolled past a message I wrote last night about the KPA100. One
sentence caught my eye: "The KPA100 is switched out of the transmit path
below 10
100+ watts."

Weird!! That's not what I meant to say. So I looked at the copy of the
message that was sent. It reads, "The KPA100 is switched out of the transmit
path below 10 watts."

Now that makes sense! Somewhere in cyberspace the nonsensical "100+" was
added to the sentence, apparently duplicated from the previous sentence
where it did appear correctly.  

That's a great excuse for my often fumble-fingered posts with typos, but
it's also a warning since we're sharing specific data: numbers, etc. If
something looks wrong question it!

There be gremlins in the system!

Ron,

Yes, it often pays to read your own posts - I often do mine too and pick up
errors like that - they MUST be inserted by gremlins somewhere in
cyberspace!!  Sometimes I have to say 'I just coudn't have written that.'
