KPA Aux cable

In the KPA cable going to the K3 the band data lines are called out, yet
there is no discussion about instructing the K3 firmware to set band
data. My band data is used for transverters with Config:KIO3 set to
TRN. If these lines are not used and band information is derived from
AUXBUS, then do we really need the four band lines in the cable going
from KPA to K3?
thanks,
Phil K3TUF

Re: KPA Aux cable

The KPA only talks on the Auxbus, it does not listen. So yes, the four BAND signals are needed.

Re: KPA Aux cable

Thanks Jack, then I must be changing my KIO3 Setting back and forth
between TRN and Normal based on HF use or VHF use? right

Phil,

Could use use the HF-TRN setting of the BAND outputs? (Page 19 of the K3 owner's manual, right column, first paragraph.)

This setting was specifically included to handle the situation where both HF and VHF band switching is required. Further details are provided on this page.

If that doesn't work, and you really have to use the TRN setting, you have two other band-switching options for the KPA500: its own front-panel switches, and RF sensing.

Re: KPA Aux cable

Wayne,
I hadn't noticed that when I first set this up (years ago). I will try,
don't see why not. Only exception is that my 6m is TRN, but that
shouldn't matter since I won't use the KPA on 6m.
Thanks,

Re: KPA Aux cable

Hi again Wayne,
This does work. My only issue is that when I'm on 40 meters my
Microwave station is on 5760MHz and so on. I will need to do something
to alert my switching system that the radio is on HF. You have the
benefit of knowing that inside the radio :-)
Is there a signal I can find that would allow me to disable the rest of
the microwave system without doing frequency decoding?
Nice amp btw,
73,
Phil K3TUF

Hi Phil,

When you're using the K3's low-power transverter output (XVTR OUT), the DIGOUT0 line changes state. We provided this to allow for external hardware decoding of HF vs. transverters. Check page 19 and let me know if this helps.

Re: KPA Aux cable

In reply to this post by Phil K3TUF

I did for a while use that signal for my transverter interface, see
http://g4fre.com/k3vhf.pdf and http://g4fre.com/K3_PTT_sw.htm

IT got messy when I changed XVn settings, so I moved onto sniffing the
frequency in the rs232 stream and switching transverters based on that, see
http://g4fre.com/K3_RS232_sw.htm
