[Elecraft] KX3-2m module

Now that the KX3 ordering frenzy is in full force, my thoughts jump 
ahead to integrating the KX3 for 144-148 MHz coverage.  Assuming the 
KX3 will only cover 28-30 MHz (like the K3) for full xmit output, I 
am assuming there will be a 2-freq. LO in the  144-28 MHz module 
(transverter).  Is there a control line brought out on any line on 
the accessory jack for controlling this?

I have a DEMI 144-28 running that can "stand in" until the Elecraft 
144-28 is ready for production.  I am getting a PLL for the DEMI 
transverter which can be programmed for multiple freq. and has logic 
control for switching between pre-programmed freq.  This will be set 
up for ch1=116.000 MHz and ch2=118.000 MHz, which permits full 
coverage of 144-148/28-30 MHz.  But I need access to the KX3 for 
switching the LO freq.

I will probably set up the KX3 in my shack for mundane duty 
monitoring 2m-FM channels.  This will also be interfaced with a TNC 
for VHF-packet.  Of course I will probably play HF-QRP with it on CW, 
WSPR, and psk-31.  It also may serve as a 6m prop monitor when I am 
running the K3 on other bands.

I am eager to install the embedded 2m module for the convenience of 
moving to-from mobile and for carry-on when traveling by air.

Looking forward to popping in 8 AA's and taking it to FD this 
year.  Bet I can be the first station that is on-air (using a 20m mobile ant.).
