[TenTec] adding xtal filter to the Orion

[Ron Castro]

We set up something like that every FD using an Orion II.  We found that the OII was perfectly clean and we could operate on the same band at the other transceiver with no interference FROM the OII, but the ICom blew S-5 wide-band noise that I could see on a spectrum analyzer.  You can't get that out once it's generated.

Those bandpass filters multi multi's use won't work either since they cover the whole band.

Our solution was to set up the antennas side-to-side about 200' apart and use a Mark V at the other station.  Worked perfect!

It would seem to me the simplest thing to do is to get one or two of the band filters commonly used by multi-station contesters. 

Our radio club uses them for FD

Off hand I don't know the exact technical name for them
