There is no such implication, I think that's just the generator he had
to hand! I can test my FT KPA500 on a generator but my generator too is
an inverting one, a 2KW honda.
One thing though when those generators are in 'econo' mode there will be
serious voltage sags whilst the
Thanks Brendan. The screenshot is interesting as it shows the sinewave

Smaller generators I've measured into resistive loads have a triangular

Your explanation of the issues surrounding QSK in the K3 is well worth the
read, Guy, and I thank you for it. I’ll stop quibbling about milliseconds on
the T-R change-over. :-)
I am not a QRQ operator, far from it; I top out at around 30-35 WPM for
rag-chew copy in my head. But in regular QSK
Hello FM,
I have a K3 with internal VHF transverter, assembled by factory.
When I key (PTT) my K3 in USB on VHF with my amplifier my power supply is
reading 45 amp even when I have no modulation in USB.
When I do the same on HF, no meter reading only when I modulate in my
microphone.

NO! The issue is the GENERATOR being happy and

Hi all,
I recently bought the Elecraft N-Gen intending to use it with Spectrogram for
K2 alignment.
It seems the latest version of Spectrogram is no longer free. Version 5 is
still free. Is this sufficient? Is there a later version which is still free?
Thanks and regards,
Ian, G4JQT
Jorge,
The input to your amplifier is not presenting a 50 ohm load to the transmitter.
Check your amplifier's manual and see if there is a method of adjusting the
input impendence on the amplifier. Some amplifiers will have an adjustment for
several bands. Look at the back of the amplifier

Thanks, Jim, got the message.
Now, I would like to use the K3+KPA500 with an unused Briggs and Stratton
2kVA generator that I fancy for portable work. It's probably the last of
the old style ie no inverter technology. I don't expect Elecraft to test
their kit with all and sundry generators
Hello all:
I expect this topic has already been discussed but I would like to
know where to get information about using the P3 with Kenwood transceivers,
specifically the TS-570 and 870. I appreciate the help in pointing me to
that information. Thanks. Chris Patterson W3CMP
Chris,
The P3 has instructions for use with non-K3 rigs.
If you are considering getting a P3, then you can download the P3 manual from:
http://www.elecraft.com/manual/P3%20Owners%20Manual%20Errata%20A7-1.pdf

Both the TS-570 and TS-870 use an 8.83 MHz IF. Go into the P3's Xcvr
Sel menu and select 8830 kHz (inverted).
The TS-870 does have a wide-band IF output connector, but I believe
you'll have to modify the TS-570 to add one.

I know how they are orientated just not which side is considered the flat side.
I have the light blue body caps that have a large flat side and a smaller
tapered flat side. All the pics I googled had the older style where it was
obvious what was the flat side.

Look at the trimmer corners - the longer end has rounded corners -
thus the rounded end. The short end has sharp corners which means that
is the flat end.

It should be fine, about the only thing you may need to do is put a
couple of hundred watts of base load on it or it may not run very
smoothly with the big changes in load that will go with keying
This would apply with any linear mind you

Hi, Fred. Please try the instructions in K3 Utility Help, Troubleshooting
MCU load failure. It has a step by step to get through this.
I presume you're using a straight cable, not through something like a
