K3 Display LCD - Cover?

Gary Bartlett VE1RGB
Can someone who has assembled their K3 please tell me if there is some sort
of protective film over the LCD display that is supposed to be peeled off
before installation?  I see nothing in the instructions and I'm reluctant to
start prying around.

    Gary, VE1RGB

Tnx, Joe.  I seem to remember from my K2s that there was such a film, but
looking under a magnifying glass it the K3 LCD, I see no evidence of any
protective material.  And of course the absence of any instructions to that
effect should be a clue!

    Only problem I have encountered so far was inserting the chassis ground
thumbscrew through the back panel into the mating connector on the RF board.
I had to loosen the rear lower screw on the left -hand side panel
temporarily to get that thumbwheel in without cross-threading, and even at
that it's a very tight fit when you re-do the side panel screw.  The
suggestion to use that technique was removed from the instructions by Errata
B8 of Rev B1 of the Assembly Manual, and I have sent a note to Elecraft
suggesting they put it back in.  Cross-threading of the chassis ground screw
in the RF board would seem to be rather bad news and to be avoided.

    73,

I removed mine (after I had assembled most of  the front panel and had to
take it back apart - grrr).

I was afraid it  might start to bubble or discolor in the future and I didn't
want to have to  take the whole thing apart.

Mine was there and very obvious. I removed it when I took the FP board out
of the bag.

Like most LCD's there is a plastic cover film added by the mfgr, but they
are removed in Aptos.

Looks like a note in the procedure to that effect might be in order <G>.

K3: PSK31 use case

Matt Zilmer
In reply to this post by Buck - k4ia
All,

I have reached the conclusion that the K3 may be the best data radio
I've ever owned or operated.  Got plenty of compliments on the audio
quality (no IMD or wide-bandwidth products).  The folks I worked -
most of them had heard of or seen the K3 [hamfests], and two of the
guys wanted their own after hearing this one.

My set up here is pretty plain so far, but I had a whale of a good
time operating low power PSK on 20m today.  

Did some experimentation before going live, and set up things as
follows.  The MON and TEST functions really help with getting levels
right.

Data MD:  Data A

TX line in setting:  20% of full scale.  The output is a laptop's
speaker jack and the setting reflects the playback volume set on the
laptop.

RX line out setting:  55% of full scale.  The input is the mic jack of
the laptop.

RX Filter:  shift it to 1 KHz Fc, and 200 to 400 Hz bandwidth.

K3 Line In Gain:  set at 5 to 10.  This range seems fine, but it won't
help to go any higher than 8 or so.

K3 Line Out Gain:  leave this at the default 30 setting.  It works
fine.

K3 Mic Source:  Select Line In.  Don't forget to put it back when you
return to voice modes.

PTT-Key:  I ran it DTR-Off, but you could also use RTS for keying.

Set up at the home QTH is as follows-
K3/10
MFJ-941 tuner
Long wire antenna - 130' long at 35' above ground.
Two stereo cables - 3.5mm to 3.5mm, both male
USB:  Keyspan USA-19HS serial port adapter @ 38400 bps.
SW:  Digipan 2.0 running on XP Pro, SP2.

I had a power setting of between 3 and 5 Watts.  With PSK31, that's
enough.

73,
matt - WA6EGJ
K3 s/n 24
