Equipment / Re: Antenna wire, what type
« on: August 22, 2015, 1724 UTC »
I picked up several rolls of magnet wire at the abandoned store previously known as RS. It's good for playing around with antenna layouts as long as it's protected from limbs, squirrels, large moths....

Equipment / yet another antenna question...near field effects?
« on: August 22, 2015, 1535 UTC »
I know that the ideal is a high antenna away from anything else, but while I'm trying to decide on my next rig I'm just playing around with my 7600 and random long wires. I have one strung along the back of a (wood) deck railing behind my house, and was thinking about running another at right angles to give me more options in terms of directionality. The question is if I have the choice of running a wire under the tree canopy, or alternatively about halfway up and along the side of the house (without any trees overhead), which one is most likely to produce better reception? Along those lines (pun not intended) is there any benefit to using a feedline since I'm just connecting the antenna to the radio via it's external whip? I realize the answer might be 'try and see what works' but thought it would be worth asking.

Utility / Re: SSTV 6940 kHz USB 0348Z
« on: August 09, 2015, 1706 UTC »
Yeah, after doing some digging I realized the spectrum didn't look like SSTV. RTTY, 850 Hz shift, 140 baud if I'm doing this right.

I think I'm hearing SSTV on 6940 kHz USB....if so, how do i figure out what mode the SSTV tx is?

Equipment / Ran across this on Amazon (cheap 1:9 balun)

I'm contemplating my next radio setup, and ran across this on Amazon:

Seems a cost-effective way to connect a long wire back to an SDR.....

SDR - Software Defined Radio / Re: DSDPlus or other trunked scanner decoding software
« on: July 26, 2015, 0238 UTC »
Duh, I should have checked directly at github:
https://github.com/balint256/gr-baz
it looks like it has an OP25 module, but even if I did get it to compile I'm not sure how to get it to work with the macports version of gnuradio I've installed. Would be really nice to get this up and running...i don't mind using radioreference but I miss having my own receiver.

Getting Gnuradio up and going is easy via Macports...the OP25 stuff is over my head right now and trying to struggle through it. The main OP25 site @osmocom has been down for a long time, but there's info at http://wiki.spench.net/wiki/OP25 and https://groups.google.com/forum/#!topic/ultra-cheap-sdr/FP5vsDXyVoE ...apparently there's been various updates and patches and it's not clear what dependencies are needed now. I was under the impression that gr-baz included the OP25 blocks but the version on Macports doesn't....

Wish there was better *nix/Mac OS X software to drive it. I do note that GQRX lists the SDRPlay as supportive hardware, so that's a start, but GQRX is a bit less beefy than what I'd like.....
