Funny you should mention that, Guy....the latest DX Monitor has me crowing in DXWWW about logging NHK1 on 891 after phasing down local CKMO-900, 10 kw at 4.7km, beamed (not tightly) roughly towards me, half ? of that distance across salt water. That was very gratifying. My phaser is based on Mark Connelly's DXP-3 design; I think that the Misek design looks like it should work with lower loss than the DXP-3, as well as getting around the LC tuned phasers' possible problems with nulling the carrier but not the sidebands. The latter problem is one reason why I wanted to try the DXP-3. In practice, I found in using Walt's Misek phaser, that they're "different" but it was hard to say that one was definitely better than the other in all or even in most cases. They're both pretty easy to use as well. If I had to choose, I'd probably give the nod to the Misek unit, but then Walt hasn't heard NHK1 on 891 yet (and I haven't heard WGY...though there was "Coast to Coast AM" last night in KGO's null). I haven't foung overload traceable to either unit yet, but have had the northern Flag give me problems; still trying to track that down . (1070 is 10 kw at 2.9 km, a strong beam in this direction (approx 2V/m at 1km per AMSTNS program), some also across salt water, but that's it for our locals) As for antennas, phasing the ALA100 against a 14m sloper has the most signal output and can be very satisfying, but the 891 logging was the north Flag against the west Flag, which in many cases requires a little more (tuned) amplification to bring the DX up, as the Flags don't have the same output level. best wishes, Nick **************************************************************************** Nick Hall-Patch Victoria, B.C.
