I tried turning off the AGC for a while but had to manually cut the RF gain so much to avoid clipping it didn't seem like a good idea. With the AGC on at least there is some possibility of weak-signa

Conditions here (FN15) not so good last night. The usual morning "bright-up" was less pronounced today. Discernable on-frequency traces for several hours and after daybreak enough of Scott's signal w
SAQ was received quite well this morning in central Canada (FN15). As an experiment, I compared two antennas: a 100-foot perimeter single-conductor loop in the trees (vertical plane) about 200' from

I'm testing an LF grabber tonight, centred on 136.18 Khz. The indicated time is UTC. Not sure if that's the best frequency to monitor but seems to be some activity there. Location is Ontario Canada.
I'll be watching too with a loop aimed right at you :-) 73, Bill VE2IQ http://www.nrtco.net/~ve2iq/grabs At 07:02 PM 2/27/2011, Scott VE7TIL wrote: Hi Oscar I'll be watching with grabber here. My lar

On the bright side, TL084s are quite reasonably priced fuses, so perhaps an IC socket would be the best investment ;-) Heh! Both the original part and its replacement were pulled from an old pcb and
We are still in the midst of a power outage here after a severe storm (100 Km/H winds) Sunday evening. It is now 39 hours with no mains power in this area. I have been able to do some comparisons of
Stefan: I think you'll find Andy is right :-) As I understand your circuit description, the output of the XOR gate will be a fixed-duration (function of your RC time constant) positive-going pulse tr
Hi Roelof: Many thanks for the great idea, it is truly a robust antenna. Bill At 03:19 PM 7/27/2011, Roelof, pa0rdt wrote: The only reports of failure are when people are accidentally feeding 100W RF
The property here is surrounded by tall trees and I can't think of any easy way to get the probe above the treetops, away from powerline. Perhaps a remote receiver, but that seems like a lot of effor
Hi Daniele: I'm using an HP 110-C and there is only one audio jack for both output and input. It accepts a 3.5 mm mini plug with a tip, two rings and a ground (or 3 rings depending on how you want to
