Hello Nicolas, I copy your signal aural and visual easily with 559 , 20Hz above IQ2MI. 73 Clemens DL4RAJ Ant.2x155m Dipol; RX Perseus http://k7fry.com/grid/?qth=JN68KJ79WJ =link&utm_campaign=sig-emai
Hello Markus, bingo,thanks for the hint. Now I can read it on my persues,too,after having set the appropriate waterfall parameters, which is a bit tricky. Unfortunately the hell signal is in the wspr
Hi Markus, I agree.Probably it was just too late for me after a loong working day ... :-) 73 Clemens DL4RAJ Grabber.html =link&utm_campaign=sig-email&utm_content=emailclient> Virenfrei. =link&utm_cam
Hi Stefan, erlizenz.jpg Is this license for ultrasonic emissions? :-) Under "Verwendugnszweck" I read "...Längswellen..." which would mean longitudinal waves,aka sound waves. 73 Clemens DL4RAJ
Hi Gary, I see no reason why you should not trust Wolf's description on http://www.qsl.net/dl4yhf/mf/mf.html#IC706_on_MF which I pointed you to in Jan/2017. What would you consider as "real confirmat
Hi Gary, This mod seems to be wrong. When dealing with mods I usually read different descriptions because they are not always correct. This helped a lot me when I opened the TX of my 7800. D60 exists
Hi Gary, glad to hear that the mod has been accomplished successfully at last. 73 Clemens DL4RAJ 90063108/msgId=7342/stime=1513456965> =X3oDMTJmOWxiZWU4BF9TAzk3NDkwNTA1BGdycElkAzg1MDgwODk1B>GdycHNwSW
Hi Paul, Out of curiosity I've done some spice simulations of your PA. They indicate that a T type LPF won't help at all. This was to be expected because your PA is not a class D voltage mode push pu
Hi Paul, No! It helps reducing harmonics output of the PA which in case are reflected by the LPF to the FET and MAY cause instability and IMD. That's why *sometimes* diplexer filters are used. They s
Hi Paul, Basically yes. But we don't know how much capacitively coupling there is between primary and secondary which might partially spoil the RF isolation. I would just give it a try: One chocke at
Hi Paul, 22 turns on one FT114-J core is more than adequate. It gives you an XL of - j1.291k which in turn means an attenuation of around 22dB (referenced to 50 Ohms) for common mode currents. So shi
A turns ratio of 4:16 gives a 1:4 voltage ratio so this ratio would require only one core. One could make one 1:4 (V) transformer or two cascaded 1:2 (V) ones, the latter probably being more feasibl
Hallo Albrecht, you are peaking S8 here. Your qrg is drifting between around 47.2 and 472.3kHz. Ant.2x155m Dipol; RX Perseus http://k7fry.com/grid/?qth=JN68KJ79WJ 73 Clemens DL4RAJ =link&utm_campaign
Hi Jim, I've found a graph showing Z_Wave over D/. Near the loop: Z_wave = 377*(2pi*D) / lambda 73 Clemens DL4RAJ Attachment: Wave Impedance.png Description: PNG image
