Hi all,
We're getting very close to a long-awaited K3 beta firmware release.
Since the changes are extensive, we'd like to send the code to a new
group of pre-testers in addition to our usual field-test group.
Please
It is a known issue with Spectravue. The only down side to the software at
the moment.

Thom,
A PSU rated for 25 amps should be adequate in terms of current for a 100
watt transmitter. Something else that must be considered, especially if SSB
is used, is that the PSU's output voltage should remain constant at all
transmitter power levels. Also the DC supply voltage measured at

Hi Thom:
You didn't state the model number. I use the RS-35M which is a 25 watt
continuous duty supply. I use an amp on most bands but operate full 100
watts on 30 and 6 meters and never had a problem with the power supply. It's
left on 24/7 and has been in operation for close to a year.

I've been using an Astron SS-30M switcher with my K3 for a while now
and previously used it with an Icom 746 for 7 years with no problem.
The SS-30M is rated by Astron at 25 Amps continuous and 30A ICS.
The ICS rating should not be confused with the widely accepted

Computer speakers are intended to play music and sound effects, not

Get a communications speaker. Mono, no amplifier, no sub-woofer.

Dan,
I see no need for a sub-woofer for use with the K3.
If you are running an amplifier, you may want to look at shielded
speakers (usually non-amplified) because those with amplifiers are
usually prone to RF problems.
The K3 has adequate audio to drive non-amplified speakers. If you use
AFX
Astron is very specific about what ICS (Intermittent Communications Service)
means: 50% duty cycle, 5 min on and 5 min off. The limit is almost all about
keeping the regulators working within their design temperature.
Astron's typical ICS rating is about 25% higher than the continuous duty

Phil,
I agree with you - whatever speakers are used they should have
reasonable fidelity.
Yes, communications quality is all that is needed IMHO for the audio,
but also IMHO, the speakers are *not* the place to achieve that - good

Hi Dan,
I recommend a pair of Best Buy Insignia, 4-inch, 3-way surround

Hi all,
Just a comment on speakers. I use cans or a small computer speaker,
non-amplified, for most SSB and CW work. However, I do a reasonable amount of
SW and BC listening with the K3 with the 6KHz filter and find an old HiFi combo
speaker with a 8 woofer to be most pleasant to listen to.
We've had many requests to provide an 0.5-kHz VFO tuning step size in
SSB modes. I'd like to substitute this for the current 2.5 kHz
selection. The new set of steps sizes for SSB would then be:
0.1, 0.5, 1.0, 5.0
Most operators probably don't find 2.5 kHz steps to be particularly
Very quick response from some K3 owners suggests that 2.5 kHz steps in
SSB mode *are* useful, after all -- for quickly scanning the band
(including when using the RIT/XIT control to move the VFO in coarse
steps).
It may be that 5.0 kHz steps in could be sacrificed, instead, in order
to

I may be daft but I still find the setting of the tuning step on the K3 very
complex and bewildering. Why can't I choose between the 4 coarse settings by
simply holding the COARSE button 4 times and the fine settings by tapping it
4 times? To have to go into CONFIG to do this seems unnecessarily
Hi All
I am seriously considering a K3 and would like some advice on configuration.
My main interests, apart from the normal SSB HF and DX, are experimenting
with the narrow bandwidth digital modes. 6m would also be a new band for

Keep in mind that the xtal roofing filters don't set the final bandwidth.
They just protect the later stages of the K3 from really huge signals

Hi Deane - for what it's worth.
I think for most non-critical (non-contest, non-DX) users, the K3
standard 2.7 kHz SSB filter does a good job for CW and SSB modes. The
K3 DSP software allows you to narrow the bandwidth for CW to 500 Hz or
less. The DSP works much better than the Yaesu and
