The WA2XTF signal appears with great rugularity before local sunrise and is solid copy with no QSB noticed through the observation period. At present ( 1545 EST) (2045Z) the signal is audible and solid trace at the same time using ARGO and Spectrogram. QSB has not been a problem, and the signal is a steady and solid reference as I experiment throughout the winter with different antenna configurations / preamps. I believe you use a 1500 foot ( ~500m ) longwire - so I can certainly guarantee I will receive your signal over a 12 hour period, well past sunset. Later ( 2100 EST) 02Z ) the signal is very weak and disappears normally until re-appearing with the sun ! For your information. 73 Mitch VE3OT ---------- >From: "Andre' Kesteloot" >To: lf-amrad , Mitch Powell VE3OT >Subject: QSB on LF >Date: Mon, Mar 5, 2001, 0:33pm > > > > Rik Strobbe wrote: > >> Have heard OK1DTN for the last 2 weeks several times with good signals, >> from 559 up to 589.
