Dear Rob, LF Group, Some years ago my work involved a project to develop a set of tuned loop measuring antennas for the 100kHz - 30MHz range. To save time, we hoped, we used "modamp" ICs similar to y
Thanks Rob, I'll see if I can lay my hands on one and give it a try! 73's Nic McLean VK2KXN ? VK5ZAT I'm not much of a designer so basically MAR-6 with 100R from 5v supply and 47nf caps for i/o coupl
Mar 6 looks like a good choice,, you made me break out my MiniCkt manual I dont know how well it handles an input mismatch . The input circuit may be a bit critical but should only affect gain ,, if
I'm not much of a designer so basically MAR-6 with 100R from 5v supply and 47nf caps for i/o coupling, the parallel tuned input just a ferrite wound inductor (from a old TV board) and some caps to br
Hi Rob, Do you intend to let others on the list have enough of a circuit diagragm that they could replicate what you are building? I for one would like to build a front end to "hot up: one of my rigs
which MIMIC did you use ? Been wondering when they would get put to use on LF good simple amp with 50 ohms in/out and a simple bias solution filters needed fer sure though Bob K3DJC Hi Bob.. I used a

Rob, That might have been me and Colin/G3VTT rag chewing at 25-30 wpm. We are both in east Kent. If you would like a test then just drop me an email off-list. -- Cheers, Alan G3XAQ [email protected]
A good check for any receiver is to listen for the German utility transmission on 138.83 which is a plain carrier with a burst of data every few seconds. If your setup is any good it should be about
Hi All.. Just found this list and seems like the only sort of forum on the net to do with LF! I'm just looking into 136kHz and looking for a few pointers.. I've temporarily built a loop similar to G3
