G'day,
All this high quality digital audio is encoded and decoded in a
clean background, high S/N ratio environment. Seven and eight bit
coded telephony has a surprising quality but there again the
background noise is low. I have long had the feeling that signals
in the presence of noise jus
I have had my K3 for some time now. I have always used it with an external
speaker and at one time tried it with "Stereo" speakers (West Mountain Radio
Communications Speaker System, Powered). While the West Mountain speaker system
worked ok, I found the lower frequencies were lacking an I hate

I don't know who is loading what in this response to a query for improved
sound. Rick's question indicates nothing unreasonable or unachievable.
What amateur radio receiver cannot benefit from improvements to the audio
chain outside of the equipment itself? Additionally, he's not asking that
anyo
Ah yes the endless quest for great "tone". Yesterday there was a YL in the
Calif QSO party. She was W6RER In Butt county. Her voice was clean very clear
but what got me was the quality and tone of her voice. It was very easy to
listen to. Good tone. Warm sounding with out being mushy. But as I s
Hi Rick:
Initially, I added a pair of Motorola (mobile) amplified speakers to
my K2 (and subsequently to my K3) installation. I found that having
a PAIR of speakers on
the audio output of the K2 and K3 made a significant improvement in
my enjoyment of listening and I seemed to have to 'work' l
Rick,
Some DSP based receivers are capable of producing great audio.
Consider that CD audio is an implementation of DSP. How close to CD
quality any practical receiver can come depends on the sampling rates
and the number of bits in the A-D and D-A conversions.
Inexpensive amplified speak
This is a loaded question, like "when did you stop beating your wife?"
It implies that there is something wrong with the K3 audio.
I have used both the K2 and K3 for some time, and as far as I can tell,
there is nothing wrong in this department. There is more than enough
gain to blast one out
?Rick -
There are definite advantages to stereo speakers, as the K3 can produce
stereo audio in several configurations. Amplified speakers can suffer from
RF interference - I use Apple amplified speakers and had to open them up to
do a lot of bypassing. The K3's audio output can easily drive
Over on qth.com in the forums area (the "Talk" sub-forum) is a discussion

on the way to a more perfect receiver." Some interesting topics came up in the

- Are DSP based receivers fatiguing to listen to for long periods of time?
- The benefits
Hi Rick,
The K3 is capable of sounding smooth and mellow while listening to SSB. I
run my sound through my computer and into an inexpensive, but decent
sounding surround sound receiver...5.1 and decent Hi-Fi speakers. Only 2
channels apply...I rarely turn on the subwoofer and never for amateur r
First question to ask when somebody recommends a particular
speaker/audio amp combo: "Are you using a hearing aid?"
This isn't meant to demean anybody. It simply is a hugely important
variable to consider when one evaluates whether their recommendation
would be useful to you.
