[Elecraft] Sequencer keying with K3/XV-144 without rigblaster?

[eric norris]

Dear Elecrafters:

I am selling my TS-2000 and building a K3/XV-144 for EME on 2m as well as normal modes and digital on HF

My question is, has anyone figured out how to eliminate using a rigblaster when using a K3 with a sequencer (LNA Technologies)? 

The K3 isolates the 
audio signals, but I don't see how I can pick off the PTT without 
making it cumbersome to use on HF digital modes (sequencer not used). 
Right now I use the LNA Technologies mic cable to pick off the PTT 
coming from the rigblaster, send it to the sequencer, then it comes 
back to the rig from the sequencer (with the preamp and amp PTT 
controlled by the sequencer also).  

This requires using a serial switch--sending the computer signals either to the K3 (or TS-2000) directly for all other digital modes, but sending it to the rigblaster when using 2m for EME.

I would really like to find a solution where I don't have to constantly swap cables, or cut into the XV-144's PTT line to send it to the sequencer since this means I would then always have to use the sequencer for 2m.  

Any and all help appreciated. Please reply to my email directly.
