Equipment / Re: Electronic Dog Fence Wire as Antenna
« on: November 05, 2017, 1618 UTC »
I always wondered about using electric fence wire...or even better, the stuff that's got wire woven into a nylon rope. I have had some success with temporary antennas using magnet wire and plastic thumbtacks....

Shortwave Broadcast / Adventist World Radio-India? 15150 kHz AM 1525 UTC 5 Nov 2017
« on: November 05, 2017, 1537 UTC »
~ S5 or so. Caught what sounded like 'Punjab' when they were signing off at around 1528. Had a few very sharp nulls while listening....carrier and all.

AAM3 (plus another station that I didn't catch the callsign for) giving out frequencies for military/amateur interoperability infrastructure reporting exercise COMEX 17-4:
5346.5 kHz SE US
5337 kHz NW US
5371.5 kHz(?) SW US
5403.5 kHz Central US
5330.5 kHz NE US
Followed up by reports coming in on 5330.5 kHz.

SDR - Software Defined Radio / SDR-setting I/R gain?
« on: November 05, 2017, 0328 UTC »
Could someone explain the difference between the gain settings in SdrDx for an AFEDRI SDR? You can apparently set the RF gain at the SDR itself (in the SDR setup menu), but there's also a slider for I/R gain in the main software window. How does one go about finding the optimal gain settings?
Thanks,
Robert

Hmm, could be an image but didn't sound like broadcast am...I tuned out after a few minutes anyway. Chris, were you running SDR recording that you could check back against?

Music, perhaps Spanish lyrics? Weak w deep fades into central MD. Posted here because I didn't see anything on the normal software schedules at this freq.

Software / Re: MultiMode updated to version 6.7.2
« on: July 25, 2016, 0202 UTC »
I noticed something shortly after posting...apparently there's an option for AFEDRI-net audio now....

This might be a silly question, but how does one pipe the audio stream from a SDR to multimode? Soundflower or the like?

SDR - Software Defined Radio / AFEDRI net-SDR (now with vhf!)
« on: July 19, 2016, 0017 UTC »
Oh joy. Ordered a radio from Alex and I'm having a blast. Had no problem getting it connected with sdrdx (hint...don't use a crossover Ethernet cable if you're running a Mac). I've got my discone plugged in for vhf, and a h800 connected for HF....and sdrdx is apparently good for the vhf side of things too. I haven't tried scanning with it yet but that is next on my list.
I think this will do just fine...at least until someone commercializes PA3FWM's web SDR and its 30 MHz of bandwidth.....

SDR - Software Defined Radio / Re: New Cloud-IQ from RFSpace

Sill waiting for the Cloud-SDR. Might be tempted to get an Afedri in the meantime....especially since they have one with VHF coverage now....

SDR - Software Defined Radio / New version of CocoaRTLServer for Mac OS X
« on: May 16, 2016, 2255 UTC »
Ah, I was wondering if that might be the case. In a sane world (or if I were retired!) I'd play around with a packet sniffer and router configurations.
Since the only driver was wanting to use a faster Mac....I'll use the very decent workaround of remoting into the radio computer and piping the audio through software.

SDR - Software Defined Radio / Re: New version of CocoaRTLServer for Mac OS X
« on: May 15, 2016, 1540 UTC »
Hi Chris et al:
I'm blowing the dust off my old iMac and RTL stick setup, and THANKS a TON for CocoaRTL server...it's nice to be able to use SdrDX now instead of the patchwork of other software i was using.
It's working great on the local machine, but I was trying to access the RTL stick remotely (but within my local network) and can't seem to get a signal. I'm able to get SdrDX to connect to the server (both SdrDx and CocoaRTLServer show connectivity) but absolutely nothing is coming through on the waterfall to indicate the signal is being processed. SdrDX is in 'run' mode, and i've adjusted the I/R to an appropriate level, and my firewall is set to allow SdrDX to communicate (or at least accept incoming connections....)
Any idea what might be going on?

Equipment / random question...SATCOM antennas?
« on: September 20, 2015, 2216 UTC »
I've seen a few plans for homebrew UHF satcom antennas online (looking at you, Chris!), and apparently military surplus antennas show up on ebay from time to time. Does anyone know if there's a reasonably priced (for argument's sake let's say <$200) hobbyist grade antenna available on the commercial market?

Any cons to using rg174/u coax as feed line? It's much easier to snake through the window!!
