[Elecraft] K2 to MacLogger Connect?

[Jack Shrawder]

While waiting for your K3s, I wonder if anyone could help with a K2  
to MacLogger connect problem?

My K2,  3256 refuses to connect to my MacLogger program. About a  
month ago a connection problem surfaced one day after several years  
of reliable functioning.

The problem symptoms are: When "Radio VFO" box is checked, ML reports  
Not Responding  and Radio… No Data.

The system is:
K2 to Keyspan USA-49WLC  serial to USB,  into a MacBook Pro running  
10.4.10 and MacLogger 4.3.2.b16

First, repair idea was to check  in the K2 menu to ensure the Port is  
"On"; it was. Then, attempted to fix via the following; downloaded  
the latest Keyspan driver (2.4), tried different ports in the Keyspan  
converter, tried different radio setup parameters for the KIO2.  
Checked K2 operation with the KAT100 tuner which runs off the KIO2  
interconnect cable, (KAT100 seems to function normally with the  
KAT100).  Not sure if this a meaningful test of KIO2 or not. Checked  
KIO2 plugs for good solder joints and for opens or shorts at each plug.

Next, tried to a MacLogger connection with my K2 via an older  
PowerBook G4 with MacLogger 4.3.2 and latest Keyspan driver  2.4 with  
same "no go" results.

In desperation, replaced USB cable from computer to Keyspan  
converter--no change.

Can anyone give me anymore tests or things to try to solve this  
problem. I'm stumped at this point.

Thanks for any ideas,
