Re: [Elecraft] Strange behavior of P3

[Martin]

Hi Paul,

many thanks for Your info.

It seems to me, the P3 under certain conditions displaying an USB cursor 
if the subreceiver is switched to LSB (Problem #1) is also a bug in the 
firmware ?

Problem #2 is a bug in the P3 firmware.  With the new K3S there are
additional steps in both the attenuator and the preamp that the P3 is not
taking into account.  This will be fixed in the next P3 firmware release.

kind regards,

Re: [Elecraft] 75 ohm cable on Buffered I.F. Output?

[Fred Jensen]

No.  What will matter is the quality of the connectors.  The 1st IF 
output from the K3 is low level, the P3 is basically a fairly sensitive 
HF receiver, and bad connectors can create all sorts of problems.


You didn't give a S/N range for your K3, but there is a simple mod 
[destroy one surface mount resistor and replace it with a non-SMC 
resistor] that will raise the IF output.

For that short distance, it will not matter if you use 50 ohm of 75 ohm 
coax.

[Elecraft] 75 ohm cable on Buffered I.F. Output?

[Bert Rollen]

All, 

 

I am setting up a LP-PAN with my K3.

 

Will I cause much problem by using a 75 ohm jumper on the IF ?  (I happen to
have several fairly nice 24" Belden 8263 BNC jumpers on hand).  

 

 

Thanks,

 

Bert

Re: [Elecraft] P3/SVGA help..

[Paul Saffren N6HZ]

There are LEDs on the P3 front panel and on the SVGA board, both should be
blinking.  If you plug a keyboard or USB thumbdrive into the SVGA board, you
should see another LED light up on the SVGA board. 

The next thing to try is a parameter reset on the P3.  Do that holding down
the MENU key and then tapping the POWER key.  This will reinitialize any
settings so you may first want to save the P3 configuration using the P3
Utility.  

Next check the revisions of the all the FPGA files located on the SVGA
board.  You mentioned that you upgraded the firmware, but maybe one of these
files could be corrupted (they control the video chip).  Rotate the encoder
to the SVGA sub-menu and then enter it.  Rotate the encoder to select SVGA
FW and select using a push of the encoder.  You should see 1.04 in FPGA 0 to
FPGA 4.  

If none of that works, email me directly at Elecraft.  My email address is
pauls at you know where dot com. 

Kind regards, 

Paul

I have a new to me, Used K3 that looks to have a setting or audio problem I
can't figure out.

 

The problem I'm having is the CONFIG setting for "SPKR+PH" is set for Yes
and the audio is working the way I understand it to work (Both Speaker and
headphone audio at the same time).

 

But when I change "SPKR+PH" to NO I only get Audio if the Headphones are
plugged in, when I unplug the headsets NO audio comes out vis the internal
speaker and the radio audio is gone.  If I then go to the CONFIG settings
for for "SPKR+PH" and change it back to "yes" then the internal speaker then
provides audio again.

 

What am I missing?

 

No second receiver is installed if this has any impact.

 

I own two other K3 radios and they do not act in this manner.

 

 

Thanks for any help

Re: [Elecraft] K3 SN89XX Audio Problem Help please

[Lyle Johnson]

Bill,

Try this (from K3 firmware release notes0:

MCU 4.86 / DSP 2.83, 6-9-2014

* REAR HEADPHONE JACK CONTROL: The rear headphone jack (on the KIO3) was 
recently changed to a different type whose speaker-cutout switch logic 
is inverted from the original. If speaker audio is missing even without 
phones plugged in, you'll need to change the setup. Locate 
CONFIG:SPKR+PH, then tap '1' to switch to "PH.R SW-" (inverted). Tapping 
a second time reverts back to the original setting, "PH.R SW+".

Noter, there is no Mode "TX DATA”.  The “TX” is an icon with an arrow pointing 
either down to it, or up to it indicating which VFO (A or B) is the transmit 
frequency.  It jujst happens that the MODE “DATA” is next to it.

[Elecraft] Strange behavior of P3

[Martin]

My P3 shows some strange behavior when combined with a K33 (newest firmware on 
K3S and P3):

1. When the subreceiver is turned on in LSB mode (listening to a qso on the low
bands) and VFO B cursor is also on, the cursor VFO B changes from LSB to
USB, if the mode of the main receiver is changed from any mode to TX DATA 
(Submode
DATA A). Although the K3S is still receiving in LSB on subrx, the P3
shows USB cursor.

2. When turning on ATT (K3S) the signals on P3 screen (and SGVA Monitor)
drop down. They remain stable at the same level if PRE is turned on. When using 
my K3 the
signals remain always the same level. On the high bands (12 or 10m) the
signals on P3 drop when activating the preamp 1, they drop even more when
activating preamp 2.

Any explanation for this behavior of P3 ?

73s, Martin DK8ZJ

Bill,

Check the SPKR setting in config menu.  Set it to 1 if using only the 
internal speaker.  If using a pair of speakers plugged into the rear 
speaker jack, set it for 2.

[Elecraft] PX3 Text Mode Guide and Lulu Discount codes

[Cady, Fred]

Hi All,

http://www.ke7x.com/The-KX3/the-elecraft-kxpa100-px3-and-2m-4m-transverter has 
a free pdf file that explains the operation of the PX3 Text Mode that is now 
available in the PX3 firmware 1.39.  This has KE7X's analysis of how the 
firmware is currently working  but we should note there may be changes in the 
future.

Also, for those looking for printed copies of the KE7X books, 
www.lulu.com currently has a 15% discount on print books 
(not pdfs).  Enter the code GETIT15 (upper case) when you complete your order.

73 and cheers,

Re: [Elecraft] 10 MHz Reference Oscillator

[David Anderson]

BG7TBL also makes a matching 8 output sinewave distribution amplifier. It also 
contains another Morion 10 MHz OCXO which switches in automatically if the 10 
MHz input to the distribution amp is not there. You can usually get a good deal 
on the GPS reference and the distribution amp together on eBay. I was actually 
just looking for a distribution amplifier when I stumbled across both items.
