K2 second RX etc.

Bob Whelan
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.

RE: K2 second RX etc.

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

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 !!
