Great signal 6955.0 AM 15 over.  Playing a song for Andrew Yoder a couple hundred miles east of me at 0118.

1720 is one looooooong antenna.  Well if 6900, 25, and 50 are out, I was thinking since a lot of stuff is AM and probably crystal controlled 6975 since you can always shorten the antenna.  Maybe 6875 as the next closest alternative.  Otherwise let me know where you get those 6935 crystals.  I'd love to see a device you can plug into an ft243 socket that would let you tune some up or down.

Back left on the Rickenbacker though it was dubbed for sure.  This was damn scary.

The blue pvc "indoor" Wellbrook has the guts sealed in resin as part of the loop.  The aluminum outdoor one has a modular piece that sits at the bottom attached with screws.  They cost the same.  I didn't hear any difference in them in my high noise environment when used indoors mounted to a small tripod and manually turned.  Go for the aluminum definitely.  Sturdier and modular.

Just a hint of a carrier here as well.

Equipment / Re: Wellbrook ALA-1530 Magnetic Loop Antenna
« on: May 17, 2014, 0022 UTC »
Mine arrived yesterday.  1530 indoor (PVC,not Al) model.  I got the needed RF adapter today and mounted on a photo tripod. 
First impression is not super, but I'm not unhappy.  I have horrible S7-9 power noise over much of the spectrum under 10mhz.
My S level on 6900s went from S9 on the vertical to anywhere from S1-7 depending on the loop direction.  S1-2 sounded about 3/4 as static-y as the S9 on the vertical.  No huge noise reduction to my ears when there are no signals, meter says otherwise.  Hams on 7000s sounded a little less noisy.  But this is just my first hour messing with it over dinner.  Hope to do some good comparisons on 40m tonight and tomorrow, so somebody give me a reason to haul my fat ass upstairs to listen to a real signal.

500-2000khz had a significantly more pronounced buzz than with the vertical.  I was able to null 3/4 of the signal, say 890 WLS Chicago, so it is functioning when rotated.  S meter said things were much better, ears said otherwise down low on MW.

Hmmm. a little before 2300 when I first listened it sounded like a simple AM carrier on 6947.5.
Now at 0215 it sounds like some simple data transmission like fast morse code and I can't tell the precise frequency anymore.

It would be cool to know how to do this, but I would choose to stick with my $15 go phone which I'm sure would kick that raspberry pi in the nuts as far as being a usable phone.

Did you identify the source of your noise?  Wasn't it electric supply close to the house?
If so, I might have to give one of the Wellbrooks a try.  Probably an indoor model.

Nice even 5 to 10 over 9 (mostly 5) to NE IN.

Equipment / Re: Timewave ANC-4 Noise Cancelling Antenna
« on: April 02, 2014, 2145 UTC »
I tried one several years ago.  I have bad electrical noise.  Any time ANYTHING in my fusebox is turned on, there is instant S7-8 buzzing noise pretty much everywhere under about 8 mhz.  I tried everything with that timewave.  Every size and orientation--like from 6" long stub to small dipole trying to null the noise.  I had high hopes since my main antenna is 20-30 feet away from the house.  It never did crap after 2 weeks and I returned it.  No reduction in noise no matter what settings or antenna tried.

Call the po po and say there is a strange van that keeps watching you. Walk over while on the phone and ask if you can help them with anything.
Stare back with binoculars.  Post a pic. Make contact with truckers on 19 and shoot the shizz.  Give them something to listen to under 4 watts.  Bore them to death.

He was on the last Tosh.0 as well.  Tosh was nice to him.  Can't wait to watch Dr? Pheeeeal.  I can't stand watching him he is such a pathetic excuse for a therapist and almost as much of a media whore as Dr. Oz, but I will watch for Boomer.

The RF Workbench / Where do you go for schematics?
« on: March 23, 2014, 0154 UTC »
For anything other than 40m AM rigs?  I was thinking a hifer beacon that would let off a pip every couple seconds would be a fun experiment.  Or something for AM in the 15mhz range?
Thanks
