Using the KRC2 with the K144XV inside the K3s

Bill Schwantes
I’m using a KRC2 with a K3s to control transverters and a homebrewed band
switch system.  At present I have limited my drive needs to the 28 Mhz 0dB
and all has been well.



I’m considering adding transverters that utilize 144 Mhz drive and 0.1 to
1.0 watt drive level supplied by the K144XV internal 2 meter unit in my K3s.
I’m a little fuzzy whether the KRC2 will recognize an “INT. TRN 0-9”
address through the Auxbus pin #2 of the K3s ACC (Accessory I/O) port and
provide the needed relay driver outputs.  The owner manuals of the KRC2 and
K3s are not clear.



Has anyone been through this?

Bill,

I have not been through it, but in addition to the information on page
41 of the manual, look at the menu listing for XVn ADR on page 68.

I interpret the information that the band data information for the
internal and external addresses will be send over both the AUXBUS and
output on the BAND DATA lines.
Back on page 21, there is a statement that INT TRN1-9 have the same
decodes as TRN1-9.

Note the caution that TRN8 and TRN9 (also TRN0) will be sent as zero on
the AUXBUS.

I think that also means you can only select 7 transverters with the
signals on the AUXBUS.  If you need all 9, you will have to decode the
BAND0 thru BAND3 outputs of the ACC connector.

73,
