heard MOG 404 Khz Montague CA for the first time in the better part of a year. seems like the signal is stronger than before. And I thought it was gone forever

Really happy with puerto rico and cayman islands. didnt think I would hear these
Had to move my radio in to the bedroom because my shop is about 45 degrees F in the middle of the day and worse at night.(I know everyone not from California is laughing at that number). I thought it might be time to work on the antenna too.
The radio is a WJ DMS-105a-2, antenna is an upside down V (top hat, not a dipole) fed against ground by a 50 ohm to 20,000 ohm balun . The top hat is about 20 feet higher than it used to be and significantly farther from metal objects, and the ground I am feeding the antenna against is better. seems to work well. lots of new beacons in this list for me.

Other / Racist ramblings on 80m
« on: July 29, 2019, 0456 UTC »
wow, I have heard a surprising amount of recordings/shouting sessions on 80 meters, (currently 3908 Kc, 0454 utc, 7-28-19)
lots of sexual, anti semetic, anti/pro trump, pro rape, anti/pro religious and other dirty content
featuring callsigns which may or may not actually belong to the hams involved.
I have heard these significantly more in the last year or so.

WEFAX and SSTV / frequencies
« on: July 28, 2019, 0532 UTC »
Is it just me? or is the Honolulu Hawaii radiofax transmitter on 11090 Kc running 100 cycles low?
I am listening to all with a 1 Kc bandpass and a BFO 1.9 Kc below center frequency.
No other sites seem to deviate from their posted TX frequencies.

General Radio Discussion / Custom ferrites
« on: December 18, 2018, 1716 UTC »
Sorry for the tease subject, but I think I may be on to something.
First, something about me. In my other life, I am a potter. I dig up mud from the ground, shape it, glaze it, and make tableware.
I have a serious interest in the design and use of industrial furnaces and kilns, vacuum firing, special materials ETC.
That being said, it would not be too long a road to tool up to make custom ferrite cores, and with luck I could be able to produce repeatable results on call within a year or two.
So, what I am looking for is interest. Is there an interest in the radio and hobby electronics community for custom ferrites?
any shapes, sizes, frequency ranges that are difficult to get or heinously expensive?
Does anyone need anything that is not commercialy available?
if interest exists, I may seriously consider setting up to make custom shapes in small batches. if not feel free to tell me I am just letting my mind wander and that there is no point.
Thanks ---EC

General Radio Discussion / 160-190 Khz licenced users
« on: September 16, 2018, 1834 UTC »
I know anyone is allowed to transmit on this band given less than one watt final stage input power (excluding filament) and the antenna is not more than 15 meters in any dimension.
But does anyone even use this band, or are all the signals either unlicensed, or incedental.
I have not hear much on this and, save the odd QRSS carrier, or noise from digital devices, dimmers cars, etc.
Has anyone found out about any other regular users not in the domain of part 15?

logs for 9/11/18 0230 to 0330 UTC
received on a 70's analog receiver, inverted L, Shasta Lake, CA
YYF 390Kc Penticton BC CAN
DC 326Kc Princeton BC CAN
RYN 338Kc Tuscon AZ USA
XX 344Kc Abbotsford BC CAN

OT 378Kc North Bend OR USA
PI 383Kc Pocatillo ID USA
QQ 400Kc Comox BC CAN
MOG 404Kc Montague CA USA (this is my test signal, audible day and night, stable, and clean, i can pretty much always hear it)
MW 408Kc Moses Lake WA USA
A little surprised to hear ohio nearly 2400 miles from me. but I certainly got a positive ID.
My inverted L feeds the 50 ohm input of my receiver through a 20,000 ohm to 50 ohm isolation transformer. it really brings a lot more signal in than the loop in my shack

General Radio Discussion / gotta catch em all
« on: May 05, 2018, 0455 UTC »
90's throwback, perhaps this has been said before.
Non Directional Beacons are the SWL's version of pokemon.
1.they just say their names over and over.
2. enthusiasts will go great lengths to "catch" new and unsusual ones, including travelling to remote locations.
3. somewhat special equipment is required to hear them. and people will even get competitive about building special antennas, converters, etc.
4. the more you find, the more you know, the better you get at finding new ones.
i'm sure there are more, and I also don't know as much about pokemon as I could. Anyone find the resemblance striking?

General Radio Discussion / FCC licences
« on: November 17, 2017, 1900 UTC »
I work in the broadcast industry by day, and I found this search tool on the FCC website to be most useful, hopefully it hasn't been posted before, but I didnt find it.
http://wireless2.fcc.gov/UlsApp/UlsSearch/searchLicense.jsp
if you click on "advanced search" you can search by discrete frequency or frequency ranges. This may not be helpful for pirates, but plenty of unusual transmissions are actually legal. Pretty much any united states licensed transmission should show up here.
P.S this search can return huge numbers of results, especially as frequency gets higher, so be as specific as possible

SDR - Software Defined Radio / SDR design and architecture
« on: May 29, 2017, 2014 UTC »
Maybe this is scary technical, but is anyone out there designing or building their own software defined radio?
I think this is a project that is getting more attainable with the myriad of phenomenal parts from Analog devices, Maxim, TI and others.
If anyone has any Ideas they have been thinking of lately, let me know, especially anyone who has ideas but feels like building an SDR is a big stumbling block.
My hope if for this thread to be a source of input and feedback for people with ideas so those ideas can be further developed.
so far my main interests in sdr are;
effecient undersampling to realize higher frequencies with a direct sampling front end
use of homodyne and weaver architectures in the digital realm to reduce the dependence on processor power for demodulation
