[Elecraft] KX3 rev. 2.33: Improved NEW QSK mode, flat RX EQ in DATA modes

[Jim's Desktop]

Just finished a nice QSO on 40 meters and the right channel click using 
NEW QSK seems to be completely gone (or so low my old ears can't detect 
it).  I set the 60 meter channels up in memories using the K3/KX3 memory 
editor and tried running through the modes and used TUNE and ATU-TUNE 
into a dummy load.  They seem to work okay.  I didn't put a signal on 
the air as there were QSO's in progress on all the channels.

Channel hopping - My PX3 updates properly, changing modes and it works 
on 2 meters with the transverter as well.  I hooked up my SignaLink USB 
and checked the EQ settings - they now auto-set to no EQ when DATA modes 
are selected - Ran my HAL ST-8000 super RTTY AFSK modem through it and 
same there on RTTY.

My testing shows everything is OK, but it's possible I missed something. 
  However, I'd put it up for Beta and get a wider range of testers for a 
deeper perspective - I beat on it pretty hard, but there are some guys 
out there that could break a steel beam without even trying - LOL.

>Hi all,
>
>The attached KX3 field-test firmware is improved over the release I 
>sent most of you previously (2.32). NEW QSK mode should now produce 
>fewer receive artifacts while keying with AFX=DELAY. DATA mode RX EQ 
>should be completely flat.
>
>Please give it a good workout, using as many bands, modes and features 
>as possible, as we'd like to go to beta with this rev if possible. See 
>release notes below, which include a proposed method of testing NEW QSK 
>vs. OLD QSK.
