Other / Link-11(?) ~6945 USB 0145 UTC 28 July 2014
« on: July 28, 2014, 0151 UTC »
Hearing what other folks have ID'd as a Link-11 transmission around 6945 USB.  Tuning in on my SW7600GR (which doesn't have a signal meter) so I can't be sure of the exact freq.  Signal is moderate strength in central MD.

Ahh...that explains the signal strength....

« on: August 28, 2012, 0037 UTC »
Soldered 40 ft of 22GA wire to the center connector of 30 ft of coax and ran it out the window and down the deck bannister.  It's a bit of overkill...lots of intermod, etc but the attenuate function on the PCR1000 gets it down to something reasonable.  Here's a scan from 6MHz to ~14MHz this evening starting at around 0010 UTC or so...

As Chris says, it may be worth a try to sting it around your house. But if your house is like my house, Its a noisy RF Killing zone. I try to keep my antennas more that 30 ft from the house to keep away from the "zone of radio death." Even then, I still have trouble from my neighbor's Super Trashmaster 500kW atom smasher....or the plasma TV he has. I am guessing its an atom smasher however.
If thats you only choice, its better than nuttin. 
If you have any space some sort of "loop", pendant, or other 'closed loop' system fed with a balun you will experience much quieter reception. (The antenna wire comes from one side of the balun, and then returns on the other side of the balun. I am using a cheap Cable TV coax to twinlead balun. It probably is nowhere near perfect, but it is remarkably quieter vs a longwire.
You should try and get a blood sample from your neighbor after the next superbowl and see if he has elevated 24Na levels from his personal LHC.....

Not sure it counts as a long wire...but if I wrap 600+ feet of wire around a 12x12 room, any chance of improving signal/noise?  Or would I be better off wrapping the equivalent around the house?  OR....heh heh hehhhhhh...burying it around the perimeter of my property.....


I'm also curious....how does one pick a balun when looking for broadband HF performance?

Wish I had that map now! I miss those Coldwar propaganda broadcasts. Hilarious, good stuff :)

Oh yeah, those were always a hoot.  Straight out of 'spies like us' kinda stuff.  Speaking of which...has anyone been able to DX any North Korea broadcasts (do they even tx in English these days)?

I wrote up another blog post about sky loop antennas, this time with an emphasis on construction tips: http://www.hfunderpants.com/?p=1097

Perhaps a naive question...would a 58 meter perimeter loop (stretched along the edge of a roof) have any utility?

We had a Zenith transoceanic on the sailboat when i was a kid.  I eventually bought a Grundig YB and a Sony ICF-SC1, which were just enough to make me want better receivers.  Now i've got an ICOM PCR1000 to toy around with, and a Sony ICF-SW7600 at work.  Eventually I'll probably pick up one of the RFSpace SDRs, but first I want to get my antenna array back up an running worth a hoot.....

I still have the Zenith...I just have to figure out how to restring the *$Y$! cords between the tuning knob and the capacitors....

Equipment / this is nothing short of AWESOME..cheap SDR?

Apparently you can hack some USB TV dongles to act as a SDR:

There are even OSX ports for the software lurking around :)
