Hi LF, Despite local QRM, good copy of SV3DVO and surprisingly i found another station later in the morning, SQ7XQ ! SV3DVO: https://dl.dropboxusercontent.com/u/19882028/LF/EU60_29.SEP_02.39UTC.jpg S
Hi Markus, Ha-Jo, Thanks for your schematic. I know it from your recent post. I thought it could be an adavantage to have some LPF in front of the first stage due to DLF/153 kHz and so on, just to pr

Hi Spiros, I see your goals become farer :-) Well, JA7NI mostly runs the grabber by request. Yas/JA8SCD is here on the reflector and corresponds to JA7NI. But you can contact him personally of course
Thanks Wolf, Yes, a good idea. I will try to catch it :-) But how do i know that it is the US mains instead of a 60 Hz monitor? Is the 60 Hz from the mains more stable? I will work on the circuit and
Hi Joe, What kind of radiation pattern does the red loop have? Is it for LF? :-) 73, Stefan Am 04.10.2014 10:21, schrieb Joe: GM Joe, LF I´ve setup my RX "Big_Loop" yesterday morning for the first ti
Hi VLF, Could someone of those who are able to monitor ZEVS run a temporary grabber so one (i) can see if it is active? That would be very helpful. I've done some changes on my circuit but now the ba
Wow, perfect. Many thanks Eddie! I am right now soldering a 2nd preamp, with a LT1028. Just to comapre both, JFET and OP... Will be in the garden and use your service then (smartphone). What is the l

Thanks Roelof, Nice stuff :-) A first test showed that i have MUCH QRM in the magnetic field. The E fiedl appears to be much better. But i will give it some more tries... 73, Stefan Am 04.10.2014 21:

503 Service Temporarily Unavailable Hi Spiros, I remember you were copied by W1VD, so maybe it works to YV7MAE as well. However it will be harder to go there because the QRN is higher in YV i think.

Hi Edgar, Thanks for the comment. Well, i thought there are no unwanted signal sources in my garden, not in a radius of 400m. But maybe some HF stuff reaches the gate through the air, or some charged
Hi Edgar, Of course you were right. I thought i don't need a completely shielded box because i am in the garden and there is no electricity. But, the gate of the FET is quasi-floating and there is al
