Software / oh happy day (remote control of radio upstairs)
« on: August 04, 2014, 1529 UTC »
Nothing earthshattering, but now I can hide in my basement while listening to and controlling the radios hooked up to my *nix box upstairs. VNC through SSH to have access to the controls, and streaming the audio back via icecast2 and darkice. There is a lag but its manageable for now...i'll try tweaking some settings later.

NNSA should set up a website "NIF your stuff!" and sell the rights for the associated reality tv show to mtv.

On my car,I get much better range with the remote in the key if I use my skull as a resonant cavity

I know the feeling. Was considering putting my pcr1000 up for sale because I hadn't used it in forever, but when I hooked it up to make sure it still worked I was very happy to discover not only did it still work but was much more fun to play with than the 7600gr.

Equipment / Today's newbie post...grounding a H-800 at entrance to house (?)
« on: August 03, 2014, 1628 UTC »
Still scheming on my semi-permanent antenna installs, and am wondering what to do with my h-800. In a former life I had just run the e-probes permanently attached rg-174/u coax inside w/out any grounding. Since I'll be grounding my other antenna feeds (rg-6 from a discone and a sky loop) to the metal bulkhead box where they enter the house, I'm at a loss (ha!) with what to do about the h-800. Looking at the schematic (https://www.lfengineering.com/files/pdf/H-800inst.pdf) I think I could do the same, but was hoping for some expert advice. Even though the antenna is active, it looks to me like the coax shield is grounded anyway so grounding it where it passes through the bulkhead shouldn't matter.
Now back to ground rod pounding......

SDR - Software Defined Radio / Re: Another new SDR
« on: August 03, 2014, 0329 UTC »
i suppose there's always the afedri or SDR-IQ; other than a sensitivity much better than my Sony portable, the only other requirement i have is that the radio is controllable under Mac OS or at least a *nix flavor.

ooooh. And here I was contemplating a R75. Only three questions come to mind: 1) what's the HF sensitivity like, 2) does it play nice with GNURadio et al, and 3) how soon can they get one to my door?

After I get my ground rods pounded in and my bulkhead box mounted I'll dig out the fishing bow and see what I can get into the trees....

Equipment / Sky loop...height vs diameter
« on: August 02, 2014, 1435 UTC »
This may have already been discussed but for some reason tapatalk doesn't want to let me search through posts....so here goes.
For a sky loop antenna, which variable has the largest effect on reception...height above ground or diameter? It's a practical question since I could put a loop around the top story of my house (guessing a 28 m loop....maybe 60m if I shoot a line to the backyard trees) without much effort, but while a loop around the entire house would be twice the diameter (up to 120m perhaps, again including a treetop run) the loop would only be ~3 meters above the ground on the front . The house is on the side of a hill so the front is much closer to the ground than the back.
I -might- be able to rig up a valley span longwire, but it would be in the bottom of the valley (running SW to NE) and probably only 10m or so high so it might not be worth the trouble. That's also assuming I can get enough tension on it, otherwise I might close line folks passing by in their kayaks

Just the news (including updates on the pineapple crop) and a bit of music. Nothing terribly exciting but a good strong signal.

FM DX Loggings / Re: Skip OK to MD 1400 UTC 31 July 2014
« on: July 31, 2014, 2057 UTC »
Was quite a surprise as WAMU is usually weak until I'm out of my garage, and this was coming in at S9. The announcers were unfamiliar too but when they started talking traffic reports for OK city that clenched it.

Picked up a very strong dx on 88.5 MHz from KZTH in Piedmont, OK. Was strong enough to drown out WAMU on 88.5 MHz.
My QTH was Frederick, MD and rx was on a stock car radio(!)
