[Elecraft] K2 Dual Receive Project

[John Huffman]

I'm wondering about the feasibility of a project.  The goal would be to 
have a dual receive setup using two K2's.

One K2 (K2/100) would be used as a transceiver.  The other would be a 
receiver only.

Since I would be building the receiving K2 from scratch (this may be an 
elaborate rationalization to build another K2), I would want tow special 
features:

  - an internal jumper to disable the transmitting circuit.  Perhaps 
cutting signal or power to the driver or finals.

  - a way to bring the MUTE line out to a rear jack.

The existing K2/100 would also need changes:

  - a way to bring the mute MUTE to a rear jack. The K2/100 MUTE line 
would also mute the K2.

  - a way to bring the receive signal from the K2/100 to the K2.

I can figure out how to mix the audio outputs from the two radios.

I'm figuring that a K2/100 and a K2 would cost less than the current 
crop of $3,000 radios and yet have better basic receive performance. 
Dual in-band receive would be great in pileups and such.

I'm not looking for a SO2R setup, just smooth dual receive.

Any suggestions or guidance greatly appreciated.
