[Elecraft] K3 BETA FIRMWARE RELEASE -- MCU rev 1.94

[wayne burdick]

Thanks to your input on the last firmware release (1.88), we've made a 
number of important improvements.

For the first time, we're posting new firmware as "beta." Upgrading is 
optional: if you want to minimize your risk, you might want to wait 
until we've blessed it as a normal production firmware release. (Or 
until all your friends have it and you're a little jealous.)

We'd love to have as many thrill-seekers as possible take the plunge 
and load the new firmware now. We think it's greatly improved, and it 
will certainly clear up many of the issues noted over the past week. 
Even though we're headed to Dayton in a couple of days, we'll be 
monitoring closely for any additional issues.

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

   http://www.elecraft.com/K3/k3_software.htm

The instructions (linked from within the release notes) explain how to 
create a separate folder for the beta revision. This will allow you to 
easily revert to an older revision if you find it necessary. Hopefully 
not!

For your convenience I've also provide the release notes below.

73,

* * *

MCU 1.94 / DSP 1.73, 5-12-08

   * VOX: Increased sensitivity. Typical VOX GN settings now ~30-50.

   * VOICE MONITOR: Eliminated “scratchy” artifacts with compression set 
to high levels.

   * FM DEVIATION ADJUSTABLE:  Use CONFIG:FM DEV menu entry (default: 
5.0 kHz).

   * Flash memory driver improved to prevent occasional receive 
dropouts, “ERR PL1”, and
     “FPF LOAD PENDING” messages.

   * XMIT SWITCH IN MENU: Tapping XMIT while in menu correctly 
starts/ends transmit.

   * PASSBAND SHIFT BELOW “0.00” CORRECTED: The SHIFT control no longer 
allows
     continued rotation below 0.00. (This was occurring only with 
sidetone pitch < 500 Hz.)

   * SQUELCH/RF GAIN CONTROL CHANGES: By default, the RF/SQL concentric 
pots
     control main and subreceiver RF gain, and squelch is controlled by 
two CONFIG menu
     entries (SQ MAIN and SQ SUB). But setting SQ MAIN to "=SUB POT" 
assigns
     SUB RF/SQL pot to both main and sub squelch, and in this case, the 
main RF/SQL
     pot controls both main and sub RF gain. Setting SQ MAIN back to a 
numeric value
     restores the default assignments. Note: Squelch applies only to FM 
mode at present.
