Hi
You can see my version at http://uk.geocities.com/g3pjt@.../ I am currently re engineering this set up to improve frequency swopping etc. Stewart G3RXQ has a surface mount version of the diode switch which is FAR superior to my discrete version. But works OK and as others have said very useful for spilt DXing. 73 Bob G3PJT -- No virus found in this outgoing message. Checked by AVG Free Edition.

Bob and all,
Just one observation since someone mentioned cross-band operation. With this scheme, the Low Pass filters of 'K2T' are attached to the antenna, the 2nd receiver would ideally be tuned to a band lower in frequency than the transmitting K2 - tuning the 2nd receiver to a higher band will likely result in weak signals due to the Low Pass Filter. Same band operation should be OK. 73, Don W3FPR > -----Original Message----- > Hi > > You can see my version at > > http://uk.geocities.com/g3pjt@.../ > > I am currently re engineering this set up to improve frequency swopping > etc. Stewart G3RXQ has a surface mount version of the diode switch which > is FAR superior to my discrete version. > > But works OK and as others have said very useful for spilt DXing. > > 73 Bob G3PJT _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Yes that's right Don but in my experience that's not been a hindrance.
I will say that using a second RX with an inferior performance to the main K2 encouraged me to build the second K2 !! 73 Bob G3PJT Don Wilhelm wrote: > Bob and all, > > Just one observation since someone mentioned cross-band operation.
