I receive exactly on this qrg IQ2MI in JN45NL in QRSS but also audible. Perhaps you can move a bit up or down with qrg? Ant.2x155m Dipol; RX Perseus http://no.nonsense.ee/qthmap/?qth=JN68KJ79WJ 73 Cl
OK,you hadn't just been transmitting. Now I see/hear G3KEV,IQ2MI,DF&NM in QRSS and I5TGC in HELL. 73 Clemens DL4RAJ Attachment: QRSSS_activity.gif Description: GIF image
There's a strange signal around 476.8. Repeatedly sweeping discrete carriers within a BW of ca. 336Hz followed by block with ca. 80Hz are sent with longer pauses between the transmisssions. See att.
Here you are,see screenshot. Signal is audible but very weakly,not strong enough for cw qso. 73 Clemens DL4RAJ Attachment: G3KEV_476.18kHz.gif Description: GIF image
Chris, the point is that your Zmag is identical with Rs,i.e.no reactance (Xs =zero),hence resonance. Virtually perfect match,see Rik's calculations. 73 Clemens DL4RAJ
Hi Chris, It's primarily not a matter of efficieny but of flux density in the core What is the size of the core and your power level? Generally I would wind as much turns as feasible on the core to k
Hi Andy, you can find a discussion on false double or multiple decodes e.g. at http://w7ekb.com/pipermail/600mrg_w7ekb.com/2014-March/006324.html 73 Clemens DL4RAJ
Here as picture (screenshot from mini ring core calculator), perhaps more convenient to read (formula rearranged). 73 Clemens DL4RAJ Attachment: calc.en.gif Description: GIF image
Hello Luis, I'll give it a try tonight. RX and WSPR are running now. I know I can compete with DH5RAE and DJ0ABR regarding WSPR spots (RX-wise). I'm also quite out in the sticks... 73 Clemens DL4RAJ
Hello Andy and Roelof, Ditto here, see attachment or listen to my audio file from 2012 at https://www.dropbox.com/s/qcwvsteike2dyu1/JJY_60kHz.mp3?dl=0 JJY can be identified by its CW ID every h+15min
