[Elecraft] How2 K2 as RX with TS-450 as TX ?

[Sam Morgan]

Using the same antenna,
I want to use my K2 as the receiver
while using my TS-450S as the transmitter.

I know I will need to switch the antenna from one rig to the other,
and somehow protect and mute the K2 during transmit.
How can I accomplish this?
What circuit could I build?
Where would I find a muting capability in the K2?

TIA
