K3 and MicroKeyer MKII

[Evert Bakker (PA2KW)]

I'm trying to connect my K3 to the MicroHam MKII.

I'm struggling already for two weeks now to let the MKII to stop putting my
K3 into TX mode (unwillingly).

When I switch on the K3 and the MKII (both on a different power supply)
nothing goes wrong so far.

But as soon as the router is started, it starts to put the K3 in "pulsed" TX
(each +/- 1.5 sec a TX pulse)

If I pull the CAT (DB-9) cable from the K3, it stops.

I got the idea that there was some relation between TX pulsing and polling
the K3 for info

 

I did contact MicroHam support, did get prompt answers, but it's still not
solved (yet).

When I delete the device and create a new one (PORTS tab - SET - and select
the K3) the problem is gone.

I did set the communication speed at 4800 Baud as suggested by MicroHam
support.

I have no other application running which generates audio and might
interfere with the MKII (I think..)

 

I'm really puzzled.

I thought I might give it a try here.

If you feel it's OT, contact me direct.

Dr Evert,

 

First off all for MK2

Use separate virtual comports in the router for every Item you want to
control.

So no virtual comport sharing.

Eg cat virtual comport = ptt virtual comport must be avoided.

That can cause strange behaviour in combination with different programs.

 

For the K3

Check your PTT-KEY setting in the K3 advanced menu.

Start with disabling those setting e.g. OFF-OFF

That way you can't trigger PTT or Key via the K3's DB9 connector

You do not need those controls if you use the MK2 anyway

 

Gd luck
