Throw up some #8 house wire for the loop conductor. It is way better than the #12 wire and will last longer than the coax conductor. #8 will handle more current than you care to generate. Mike Mitch
Would you believe that was only using 500w??? Excellent signals last night from all over NA with reports of audible signals at 1000 miles. -- Mike WE0H WD2XGI Steve McDonald wrote: A nice signal here

Wait till the night he transmits while driving down the road :-D -- Mike WE0H WD2XGI Laurence This is beginning to sound like an eventual foray into /M operation on LF :) Pat g4gvw
What a mess. Mike I noticed that G3YXM was running screen grabs on 137.700 kHz this morning, with an Argo 3 second slow screen. I took a shot of the same spectrum here, and placed them side by side:
I tried a 45' tall flattop vertical with a 72' long by 5' wide flattop all hung in oak trees. It worked OK when it was below freezing temps outside and decent when the temperature went below zero deg
I think our Whitewood is Pine or Poplar trees. That's a bit large of a coil =-O Mike James Moritz wrote: Dear LF Group, I have attached a picture of GBR's wooden loading coil taken last year - the he
Hi Chris, Put up an Ashlock loop and forget about losses with trees or wires or coils or houses or rain or snow or people or animals or anything else. Just ask Laurence how well they work or maybe Ma
I was working on a Cisco router yesterday and found a bad surface mount ferrite. I asked the other guy in my department if he could look on a parts board for a ferrite bead and he returned later to s
Yes, you have to know what buttons to push to get the right answer. The calculator just helps you to not make as many mistakes if any at all. Mike WE0H I must confess that after all these years i do
Hi Jim, 2a of loop current sounds like about 2 or 3 watts power if he is running something like an Ashlock loop made out of about 1-2mm wire. But 15 miles away should have pegged your S meter. I can

Ah um...radio Warren...Boston's best...lighting up lights across the nation...changing weather patterns...providing free tanning sessions to his neighbors...keeping those pine trees warm all winter..
Maybe Mal can turn up the wick so his CW could be heard over here? How much power can you generate Mal? Warren has a 10w ERP limit which should be plenty :-D What do you think Warren? Do you have a p

Sure looks like QRSS & ARGO or another variant. How in the heck did you find that webpage? :-) Mike Hi all see http://www.nist.gov/public_affairs/releases/demolition_dcconv.htm I wonder if that was A
Hi Mal, The cost would be too high just to ship such a large item over the pond unfortunately. Our machine shop certainly could make Delrin wheels but it wouldn't be economically feasible to do this.
Maybe Mal has a big beam for 137kc and it is pointing at Oklahoma? Wonder how many prop pitch motors it would take to swing that baby around =-O Mike Nice capture Mitch - From Oklahoma, at present, s
