Hi Frank,
I would not expect the waterfalls for the JT modes to change because the JT
modes transmit only one tone at a time. Apart from turning the tx on and off,
the amplitude of the signal does not change. Therfore there is no source for
IMD that could result in a broader signal or
Chris,
I cannot answer how well the KPA500 will run when driven 1 to 5w, but
JT65 does NOT require a linear amp. It runs the same as CW, only
stepping in frequency (makes different tones in a SSB receiver), so
one can use a class-C amp if they want to with JT65.
Therefore, there is no
I've been attempting to remote my station since 2006. I finally have a setup

audio.

Trevor,
I purchased a used K3 (s/n 281) a bit over two years ago and have never had
a complaint about receive audio. I love this rig and will, in all
likelihood, never buy another rig again.
Good luck with your purchase decision.

My #930 has always sounded nice to me with a pair of high end sennheiser
headphones with far less background hiss than either the ts480 or IC7000 which
preceded it. I did the dsp board swap a couple of years ago and that made it
even more pleasant to listen to. In my opinion, even for
testing new internet and email account.

The K2 ALC indication is *not* the same as the K3 or KX3. With the K2,
you want NO ALC bars.
You are overdriving. Back off the audio drive until the last ALC bar
just goes out.
You should also check that compression is set to 1:1 (menu SSBC = 1-1).
An advantage of using RTTY mode is
Hello Trevor,
The audio of K3 may be ok for CW but it is only acceptable for SSB voice mode.
Comparing K3 with my Icoms, I would prefer the audio from my Icoms.
Having said that, I still used K3 in the recent IARU contest because of it
excellent selectivity. I used CM500 during the
I am mostly a rag chewer and enjoy armchair copy audio. To that end, I
found the K3 was sadly lacking in good receive audio. Too much hiss and
too tinny sounding. In a word, tiring to listen to for long periods of
time.
I thought about giving up and going back to my trusty TS480 with its

Bill,

Maybe I'm just deaf to the hiss everyone complains about, but I have to say my
impression of K3 receive audio is considerably different. I do have the
modified board, etc. And I haven't used the internal speaker since the first
day I finished the radio.
I do use a pair of RCA 40-5035

Hi Steve,
There really isn't much to scroll. Unlike a PC with gobs of memory, the
SVGA is using an embedded processor with a limited amount of RAM. At best
there would only be a few lines of text to scroll. A better work around
would be to go to a smaller font with a higher resolution and set

Finished the KAT100-1 tuner and I'm seriously impressed with this unit!!

I use the Afedri with my K3. Works great with NaP3 as well as SDR-Radio,

other apps that support it's networking mode. I chose it for it's

Run the wire - that connector on the K2 is an input only. There is a

That just means your preamp is powered up all the time. You can check that by

cannot use a receive antenna on another band, such as

As Don said, you're overdriving your radio. Your signal may have some
