HD15 "Y" for splitting K3 ACC

[Iain MacDonnell - N6ML-2]

For anyone needing to run multiple devices simultaneously off the K3's
ACCessory port, I've located a source of an HD15 "Y" splitter that has
all 15 pins connected through, and none shorted to the shield (unlike
most that are made for VGA use). I don't actually have multiple
accessories to try it with, but it checks out with a continuity
tester. It's part number 10H1-27708 from www.cablewholesale.com, cost
$2.40ea.

Hope it's useful to someone...

Iain, thanks for this info; finding these with all lines independently run is difficult.

Is anyone offering a breakout box for the K3 accessory connector?  Home-brewing is the obvious answer, but I thought someone might have come up with a nifty packaged solution.

G'day,

Continuing my investigation into PC noise I tried for the first time
using the CAT interface of my microHAM CW Keyer.  Basically this
provides a USB to RS232 conversion CAT interface and a WinKey.  For
more info on the other twiddly bits see the microHAM web site.

K3 on 6 metres, PR6 on, PRE OFF and the antenna port terminated with
50 ohm load.

No noise.  Quieter than the CAT6 based RS232 cable I use because
with the cable I can just hear PC noise as I task switch and the CRT
monitor updates.

Previous measurements showed the directly connected KUSB to be
approximately +10dB noisier than the RS232 cable.

No connection with microHAM other than buying a CW Keyer a couple of
years ago.

Regards,

Mike VP8NO

Lyle,

I just ordered the brksd15hdmc DB15HD Slim Male Breakout Board as it reads
and appears to be exactly what I need to use for the K3 Aux connection for
FSK operation.  Thank you for posting the information.
