Hi Daniele, I felt real guilty.. and added a reference to the authors site on my webpage. 73s Minto pa3bca -- Ceterum censeo Carthaginem delendam esse From: [email protected] Daniele Tincani S
Minto, Daniele, @Daniele: Nice to read you also want to join in on LF! BTW VLF is not forgotten here, i want to come back in September. But want to have the LF system ready for the DX season and wat
This looks like a very good design. Fascinating easy!! Is it completely grown in your head or have you seen it somewhere in the web? What is the gain, about? I know the BC337 as a low noise NPN tran
Don't worry Minto, this circuits was re-published a number of times on the web :-) Anyway, I agree that a reference to the original article may give a more complete background and might be helpful to
I havent thought about ferrite RX antenna for LF.My guess is that it is not going to work not without an external antenna coupled to the ferrite, and then whats the point? DCF77 clocks often have tro
Minto, this is the M0AYF page I referred to: http://www.qsl.net/m0ayf/active-loop-receiving-antenna.html May be you "stole" the original schematics from there? :-) Best regards Daniele From: Minto Wi
Hi Wolf, Stefan, LF Interesting might be worth a try. It is easy to set up, I already have the SA612 employed in my 137 KHz receiver. So just a ferrite bar, varco, buffered and amplified using a J310
Hi Stefan, First: congratulations with your ferrite success. Very interesting, I have already dug up some ferrite bars here I moved up the frequency range of my grabber. 73s Minto pa3bca -- Ceterum c

Stefan, LF Not my own design, I dont remember exactly where I got it but I am pretty sure I stole the idea from the Internet and possible made some changes. The bc337 was used as I have a lot of them
Stefan, LF I use the 4C6 cores in my Lowpass filter for 137. I tried the FT50-43, and the 4C6. The latter needed about 44 windings for 80 uH so its AL is 41 nH/T^2. (varies a bit per core). The AL of

Hi Daniele, Yup thats the one. My shameless theft is exposed J I see that the only thing _I_ did was re-draw the schematics (I use Kicad). Of course I should have acknowledged the original author on

Ferrite RX antennas.. been there when 136 kHz started. Not as good as a larger air-core loop, possibly noise caused by the Barkhausen effect or similar effects, nonlinearities, etc. Also beware the f
Oke, Ive changed the scrolling speed from (the default) 1485 ms to 700 ms per step. Lets see how that works out. 73s Minto pa3bca -- Ceterum censeo Carthaginem delendam esse From: [email protected]
