Now that we are 'sort of in post contest season mode' and sharing some good ideas, there is another question: During recent Field-day setups I noticed severe cross-talk issues between TX antennas and
Most use individual band filters and they almost completely eliminate the issue. At our station we used the Dunestar filters for operating positions on different bands. As for 160 I personally use t
Hi Bill, I think this is not what I meant here; I also do use BPF's and the Front End Savers. The problem is that while listening to your receiving antennas, there is also some signal from the transm
Hi Mark - I have not experienced K3 TX/RX antenna isolation problems with my station configuration. I expect that if there is an isolation problem with your rig's TX and external RX antenna routing/s

input during RX mode' ?<< There are several reasons why it is necessary to detune the TX antenna during RX, however disconnecting the center of the TX coax during RX on 160m is a MUST. If you don't
There are many heads to this snake, but also many fixes. This post is about crosstalk, NOT interaction. First, there is coupling between the antennas themselves. Cross-band interference between trans
Thanks Jim, Our learning point so far: Our fixed setups usually had harmonic coax stub filters per individual antenna. Antenna interaction was carefully measured with help of a spectrum analyzer (wor
You may find my applications note on optimizing the location of harmonic stubs useful. It's on my website. k9yc.com/publish.htm Using the technique I've described, stubs can be 20-30 dB more effectiv
