Billy,
We use three types of band filters in the club:
* ICE
* Dunestar
* Home Brew (designed by Siemens engineers)
These are inserted in the antenna line and affect both RX and TX.
In addition, many use RX-only filters. Again 3 types:
* Braun (a German brand)
* BCC's own brand ("BCC-Preselector")
* Home Brew (also designed by Siemens engineers)
NOW, here comes the most important part:
WE DID NOT USE ANY EXTERNAL FILTERS WHEN WE COMPARED THE ORION TO
THE K2 AND THE 746.
The purpose was to test the transceivers. We already knew the
filters work ;-)

Maybe? ... as in wonder if they are using any additional
EXTERNAL
bandpass filters as part of the overall station design there too?
Over
the years the Bavarian group have published several such articles
...
And I thought John, ON4UN at one time used ICE units? John ...
???

On other forums, certainly ... but this IS the TenTec forum, and
... ah ...
B-)
Happy Holidays to All.
