K3 beta-test firmware revision 2.31 is now available. This is an
extensive update; details appear below. Please send any problem reports
to ***@elecraft.com.

For instructions on how to load beta firmware, please see:

N6KR

* * *

MCU 2.31 / DSP 1.89, 8-28-08

New Features and Enhancements:

* CW SIDETONE INCREMENTS NOW 10 HZ (originally 50 Hz).

* RIT CLR switch now works during transmit in all modes and at any time.

* RIT CLR MENU ENTRY: You can use this menu entry to select ?UNDO ON? or
?UNDO OFF?. OFF is the default. When ?ON?, tapping CLR will alternate
between
0.00 and the present RIT/XIT offset, if any.

* DIVERSITY RECEIVE MODE: If you have the sub receiver (KRX3 option)
installed,
you can take advantage of ?diversity receive? by using two separate
receiving antennas.
This can improve signal copy during fading, and adds a spatial (L/R)
effect to signals.
DIVERSITY MODE further enhances this capability by slaving the sub
receiver?s
mode, filter settings, and VFO to the main receiver. To enter diversity
mode, hold
SUB until you see ?DIVRSTY? on VFO B (about 2 seconds). The kHz decimal
point
of the VFO A display will flash slowly as a reminder that diversity
mode is in effect.

Notes on Diversity Mode:

1. Entering diversity mode switches the sub receiver to its AUX antenna
source. If you don?t hear any right-channel audio, you probably don?t
have
an antenna connected to the sub?s AUX input. Refer to the owner?s manual
or KRX3 manual for information on sub receiver AUX antenna
configuration.

2. If your main and sub receiver have 5-pole crystal filters with
differing frequency
offsets, you may hear a slow phase modulation in the received audio at
some
VFO frequencies. The only way to eliminate this effect is to use 5-pole
filters with
matched offsets (available on request; contact Elecraft) or use 8-pole
filters,
which have no offset.

Miscellaneous changes:

* DUAL PB CW MIN CONTEXT BANDWIDTH NOW 400 Hz. In high-QRM situations,
a 400 Hz or 500 Hz crystal filter may be very useful as a limit to the
context bandwidth.
Note that the ?pedestal? effect (-24 dB context filter) becomes more of
a sloped
response as the context bandwidth is reduced.

* DATA TX ALC IMPROVEMENTS. PWR control is now more responsive during
transmit in all DATA modes.

* FM SQUELCH THRESHOLD: Closely matched between main and sub receivers.

* NOISE BLANKER ON/OFF ON BAND CHANGE: The DSP noise blanker
wasn?t set up properly during band changes. It may have been left ON on
the new
band in some cases.

* PA TEMP and FP TEMP are now "normal" VFO B alternate display modes,
meaning that you don?t have to set TECH MD to ON in the config menu.

* DDS frequency shifting during T/R changed to eliminate a variation in
CW
keying duty cycle that was occurring only over specific, narrow
frequency ranges
on each band. This also eliminated a related CW keying artifact.

For software developers:

* RG$ command implemented (sub receiver RF gain).

* "FA", "UP" ,"DN", ?RC?, ?RU?, and ?RD? COMMANDS UPDATE VFO B IF
VFOS ARE LINKED (except in SPLIT). These commands can also be used
in transmit mode.

I have installed the new beta firmware on #980 and am suffering agc
instability. I have returned the agc settings to default and still
experience random S meter movements to 30dB over 9 and corresponding lack
of audio output. Turning off the agc removes the problem. This is not qrm
coming from the antenna because it happens in exactly the same way with the
antenna disconnected.

I used the latest loader in windows xp.

Any ideas please? I have repeated the firmware upgrade and have also binned
the file and downloaded a fresh copy.

Hi all,

I just upgraded to the latest beta. Set pitch to 630 and then varied
the "WIDTH" and SHIFT". Set the WIDTH for 0.80 then when shifting
passed FC 0.35, the receiver dies with an error "E 00000C" ERR DSE.

It doesn't appear to matter what the "pitch" tone is set. After the
error occurs, you must change the SHIFT setting > 0.35 and power off and on.

Same firmware here.

Set pitch to 630

Width to .80

Varied shift from lowest setting to highest without issues.

There were two loads that needed to be added for this firmware. Did
you add the DSP as well as the MCU?

Looks like it was my mistake.... I could have swore that the DSP was
being loaded the first time. I went back to the previous firmware and
then reloaded the latest beta firmware making sure that I send "all".

It's good now.

Just a couple of thoughts...

1) How about enabling the firmware for the KTCXO3-1 TCXO, so that
those of us who paid for that capability can actually use it?

2) How about concentrating on creating a rock-solid code base, with
the AGC/NR/NB/whatever all functioning at their best possible level of
performance.

I will vote for the remote antenna tuner and a Syllabic Squelch.

A syllabic voice squelch would be a nice feature to have on the K3. Most commercial HF radios have these voice activated squelch circuits. They seem to ignore and noise and static very well on SSB.
