Mal, As said (even in my CW test signal text) i do not have a RX here in the moment (no headphones output). If WX is fine tomorrow in the morning i will be /p again and try CW /p. Now it is just a TX
Thank you Albert for coming in, also to Tony/HB9ASB. I actually didn't expect much activity on a friday morning. But then clear signals from HB9 and PA. Very pleased about that! It was an easy copy,
Markus, Alex, LF, Just preparing the new PA and matching system again, for 6 dB QRO. Will try to use that tonite for a 12 Mm DX ;-) Replaced the old tank circuit caps by a more suitable cap combinati
Wolf, Which dimensions has your ferrite rod had? Never thought i will find a source for rods that are longer than 10 cm but see: http://www.box73.de/catalog/product_info.php?products_id=1422&osCsid=r
Ah, hello Jim, LF, Just read your mail, a bit late ;-) At least now the band seems quiet. Not sure how it will be in the evening. Since i want to try from /p i need a sked, at least 2 hours before. D
Hi Alan, We'll see. I just bought 16 pcs. 140 mm length and 8 mm diameter ferrite rods for 30 EUR (transport included) on ebay! 16 were available. The mu is 400, as written there. I hope the ferrite
Hello Peter, Thanks for the link, very interesting and relating to the current discussion :-) I expect many of us are reading the dissertation right now ;-) Especially fig. 5-16 on page 139 is intere
Hello Alex, Chris, LF, Thanks for monitoring. It is interesting clearly to see in picture B (what others said before) that just before the local sunrise of the RX (in that case) the signal levels are
Hello Minto, Well, the signal is dark blue at the DF6NM grabber so probably it is G3KEV or PA0A. Since it is rather poor at G4WGT, i would guess it is PA0A. Or someone else who is rather seldom activ
Nice signal Mike! My grabber is back, after repairing a broken wire. The frontend is still a bit wet, so out of resonance and thus a bit darker. Anyway, good reception of your signal! Looking forward
Hello Jim, Piotr, Alex, Markus, Chris, Mike, LF :-) Thanks all to this interesting observations and your reports about the LF ferrite antennas and propagated signals. I'm sure there will be more usef
Hello Jim, tnx for comments. Am 13.08.2011 02:28, schrieb James Moritz: Dear Stefan, LF Group, These metallised film capacitors are "self healing" - if a voltage breakdown through the film occurs, th
Hi Alan, Yes i know, but these caps perform very well in a my PAs so far. Have never had a problem with them. The are rated at 2 kV DC and 700 V AC. I alwyays ignored the 700V AC level. But probably
LF, Just found that picture that nicely shows the Spectrum vom DC to VHF with the correct band segments. http://www.stormwise.com/spectrumusage.JPG Often we read about ZEVS is an ELF transmitter and
Hello Jim, What a surprise, i didn't expect such a story as a result of my spontaneous transmission ;-) Congrats to your compact and well performing antenna which will be good for holidays and /p, if
Jim, LF, I will go out of the city now, for a CW QSO on 136.5 kHz. Have already prepared the LF system and link. No lightnings so far in a radius of 1000km and above. QRV in 30 Minutes. 73, Stefan/DK
Hello Alex and tnx. Currently i'm running 120W RF power and just lost a 10A fuse ;-) Now replaced by 16 A, HI :-) The current seems to be slightly above 10 A and QRSS-60 seems to be well above the th
Two things: If there is almost no activity on LF, why is then QRN/QRM a problem? Or would there really be more activity if QRN would be lower? I can hardly imagine we would have a full band or at lea
LF, Good conds on LF tonite again! After trying to QSO a bit i will attempt to leave a stable beacon signal using the nex TX converter. The SL TX session is not locked to GPS yet since the freq jumps
On 2nd...4th of September i will be in France again, transmitting on 137 kHz from JN29OD96TK I will use a 200m vertical antenna (if i get the permission from the french OMs), a good earth and decent
