Fw: K3 2803 Firmware Problem

The problems continue with K3 #2803
The problem is still unable to load FPF or DSP firmware. MCU loads fine.
I have used two different computers in an attempt to load the firmware. On
each computer I have used the KUSB and a 9 pin straight thru serial cable.
That doesn't work.
I have reloaded the K3 utility to make sure it is the latest version and
still no luck.
In numerous e mails with Gary we thought trying a new front panel board
might work. Wrong , After installing a new front panel board same problem.
On page 63 of the owners manual if I hold in the shift / Lo knob while
turning on the power I am suppose to see EE INT. All I see is ERR EE2.

The K3 is a nice looking radio and maybe one day it will work but , Right
now , Very frustrated to say the least.

You can ship the radio back and have Elecraft check it out. If it is a
board problem I believe they will take care of it for you.

KRX3 antenna input

I spent the morning installing a sub rx in my K3 #1516. All is working
well. I set it up using the KAT3 ant2 as input the the sub rx. Now I'm
thinking that there is no advantage to doing it this way(other then me being
too lazy to install the aux bnc connector). Does it really matter, is there
any advantage to using the bnc as an rx only input? I have a four way
antenna switch downstream from the K3 so there is no advantage to the ant2
not being used by the main receiver as all antennas come in through ant1.
The ant2 input would go unused otherwise. Is the bnc rx input better, is it
worth taking my K3 apart to install the BNC rx connector ? All 150 to 400
answers welcome...

Re: KRX3 antenna input

The setup I use with an array solutions six pack remote switch is to
have ANT1 and ANT2 both going to the six pack. This way I can mix and
match any of my available antennas to optimize diversity receive.

Hi Jeff:

One possible problem is that if you were to accidentally press the ANT
button you would transmit into your receive antenna.

KRX3 antenna input

In reply to this post by Jeff kb2m

There's one ... at least ... condition where the BNC input jack
and cable is useful. I bought the 2nd RX -only- to monitor 6M
for band activity while I'm using the radio on other bands. The
BNC allows me to connect a 6M GP to the 2nd RX. My ANT 2
connector is connected to the 6M beam.

A tip: The cable from the BNC is -much- easier to plug into the
2nd RX by removing the KIO3 panel and the boards behind it
than removing or even partially lifting the 2nd RX to connect the
cable to the input.

Re: KRX3 antenna input

Thanks for bringing up the attenuation issue with using ant1/ant2. Has
anyone tried it both ways and have any comments?

Re: KRX3 antenna input

I have reported to Wayne that the Pre and Att memory goes across both the
receivers. I thought they were independent. He has responded that it is
under investigation. Perhaps this is the issue Jeff is bringing up.
