[Kenwood] RE: TS850SAT and optional filters

[Hsu, Aaron (NBC Universal)]

Someone a while back posted links to graphs showing the effectiveness of using slope tuning in conjunction with filters.  I have the links somewhere, but can't find them - can someone repost the link(s)?


Thanks!

Jorge,

I have them both installed in my TS850SAT. Theoretically there is not much difference between them, see http://www.qth.com/inrad/graphs/103.gif and http://www.qth.com/inrad/graphs/22.gif

The -6dB / -60dB  bandwidths are 460 Hz / 985 Hz and 367.5 Hz / 845 Hz for the filters. Not much difference but in CW it is good to have also the 250Hz #22 as well as the #103 and both are wide enough for RTTY operation.
