I did a head to head comparison between my K2 and a near-mint TS-830s. The 830s had dual 500 Hz factory filters (one in each IF) plus VBT to narrow things even further. The K2 is a late model unit and I put in 2 ground connections on each Xtal in the filter (per instructions).
I found the K2 to be better at ultimate rejection than the loaded 830s. I also found the K2 to be a tad narrower than the 830s, even with the 830s VBT narrowed down. The 830s just didn't have the steep skirts nor ultimate rejection. My testing was done during a big CW contest when there were lots (lots!) of strong signals on the band. K2 won over a well respected rig. I find it really hard to believe that a starter rig (718) would have better filter performance. May be so, but you'd have to prove it to me. Makes me think the K2 isn't quite right yet. - Keith N1AS - - K2 5411.ssb.100 - _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
