Re: [Elecraft] Resetting K2?

[Petr Ouředník]

Fred,

be carefull with the K2 reset...

My friend tried to make keying circuit for K2 to be able to keying his K2 from PC with diodes 1N4148 or so. After turning ON the K2 completelly crashed on there was not possible to do anything except  the factory reset. 

After factory reset the K2 had BFO frequencies out of range, TX does not work etc. :(  After going thru the BFO settings procedure seems that RX works well again but I do not know what happened with TX during the factory reset. (anybody know please?)

So I can recommend to be carefull with factory reset as You can spend long time with re-alignment Your K2.
