Yes. "Weak signal" does
Because it’s weak signal at the receiving end; you use what power it takes to
succeed in making the contact, up to the legal limit.
On 160M, 1500 watts out is common.

Good Evening,
Snow, rain, and hail fell each day this week. The daffodils which
sprouted a few weeks ago have yet to bloom. But the forecast is for sun
and maybe even 50 degrees on Monday. I had many plans for spring and
summer; most of them will have to be postponed.
There is a

Just quoted what is in the K3S manual. No interpretation provided. I
agree that 100 watts key down is a lot for a SSB amplifier running in CW
mode. To me that says 100 watts for 10 minutes and then RX for 10
minutes. Otherwise equal TX and RX times. Who does that?
Running FT-8 or PSK-31, I see 60 C from time to time. Some bands I see
the temp rise much faster indicating less efficiency.

Hello,
i ordered a Colibrì Nano USB SDR.
and i am thinkg to connect the Colibrì antenna through the RX ANT OT of
the K3s tu use the colibrì and his software like a panadapter for the
K3s.
The colibrì can't accept "IF OUT", so i will use RX ANT OUT from XV3B to
give antenna signal to the

"Does "100% - 10 min, 100 W key-down" mean that if you key down without stop in
CW mode it can go 10 minutes at 100 watts? That seems like an awful lot."
If you want to know what it actually means you'd probably have to run a test
and record the PA temperature. Does it reach maximum value
Thanks for the replies.
I've enabled the PA temp display (currently showing 22C right after
power-up but before transmitting), and will keep an eye on that.
Bob, I noticed that line in the K3S manual about the CW/SSB duty cycle.
Does "100% - 10 min, 100 W key-down" mean that if you key down

You have the Signalink w/the module or the one w/jumpers? Several of my friends
have had trouble w/the Signalink w/the module, I have two Signalinks, both
w/jumpers and don’t have any issues.

David,
I think you should check the jumpers in the SignaLink. Also make
certain the level controls for the SL soundcard are set correctly in the
computer.
Or simply use another USB soundcard - the K33 has built-in isolation
transformers.
Set the K3 LIN OUT level to about 10.

I suspect this item might be several months after they start shipping the
radios. Dust off your “crystal ball”.

I ask “why use a SignaLink with the K3?”
The K3 already has buffered Lin In and Line Out. Separate settings for in/out
for each mode.
The one item to pay attention to is transmit audio level. You should set the
power out by using the Per knob on the K3 front panel.
Then adjust the audio to
I have been using digital modes for years and have a number of SignaLink USB
devices which have all worked very well with a variety of rigs.
I am new to the K3 and have bought the Tigertronics cable and module set to
allow me to connect a SignaLink USB to the rear Line In/Out and PTT
