SIO 111...i've got the carrier on the waterfall and can hear the occasional word or two.  maybe someone with a better antenna can pull this in.

Yeah got it here.  She's blabbing about 'bad boys', and occasionally a male voice will cut in "testing, hello?  hello?  hello?"

S3-4 here

Sounds like hymns in Spanish?  About S2, lots of fades and noise.

Sorry to be a pest...but still getting the 'beta expired' error.

Hi all.  It looks like the beta of mySDRPlayback has expired....and the 1.0.0 version is the last one posted.  Does anyone know of an alternative that will let me demodulate and extract audio from an I/O file?  Thanks!

SIO 555 in Central MD.  Solid S4.

How about some Black Flag?  (THANKS!)

S3-4, SIO 344; some minor fading.  Overall good copy.

I can see the carrier in Frederick, but it's way down there in the S1 weeds for me.

Peaking to S2, but mostly down in the noise weeds.  Can make out music and singing

Can see a carrier and music occasionally pops up, but signal bouncing around S1. Amazing as short-wave.info has this as a 100kW transmitter out of Madagascar....

S2 here...Charlie Daniels at 0107Z?

Equipment / impedence mismatch question
« on: September 02, 2018, 1559 UTC »
This is based off an observation i made trying to hook my H-800 directly into my afedri while on a road trip.  The receiver's HF input is 50 ohm per the specs, and the H-800 uses RG-174 (50 ohm) so I didn't anticipate any problems.  HOWEVER, the power supply box for the H-800 (the antenna probe receives power over coax from the box, and the connection to the receiver is on the box) uses RCA-type connectors for some reason while the afedri has those tiny SMA connectors.  No problem i thought, since i have a spectrum of various adapters.  So i hook everything up, with an RCA to F-type coupled to a F-type to SMA which is plugged into the afedri (I did NOT have a RCA to sma hence the workaround).  Long story short..the receiver was deaf as a bat.  Thinking there might be a problem w/ the H-800, i decided to rig up an improvised LOG using the RG-174 as it was the only coax i had.  Still nothing...which was very odd considering i've had very good luck with LOG from that remote location before.  The coax was visibly intact and had good conductivity between the ends.  I finally considered the option that there might be an issue w/ the adapters and did an improvised connection (e.g. cut the RCA off the coax and directly made conductivity between the coax and the SMA connector on the radio) and BOOM!  everything working great. 

So...the adapter seems electrically fine in terms of conductivity.  My working theory was that there was a problem with the 50 ohm-75 ohm-50 ohm mismatch between the coax, the adapters, and the radio.  Does that make any sense at all?  If so...why do i get OK results going from an antenna through 75 ohm RG-6 and into the radio with an F-type to SMA connector?
