Re: The old and the new :).

Radio Shack DX-390 portable and RSP1 here. The "old" receiver is near my bed. I guess probably because my resting heartbeat is close to 60, but I've always found listening to WWV soothing when going to sleep. There's just something about the perfection and regularity of those signals... Or...

Re: Frequency Sweeps? What? Who?

I have a background in data comms, having worked on modems and such things in their heyday. I've imagined that the wide, smooth "whoosh whoosh" signals are some kind of digital signal with phase modulation. That they look like rope is I think a product of propagation quirks. And yes, I do ...

Re: SDRuno suggestions...

I can't seem to edit posts. No matter. Here's another bug:

  • The Minimize All function often misses minimizing one of the windows. Also, It'd be nice if it worked whenever any of the windows was minimized or restored.

Re: Shortwave Radio (aka HF 2000-30,000kHz)

>I can get lots of HAMs ...there should be hundreds..right ? That's hard to say with any certainty. Bands can open and close by the minute, and not every ham is on the air all the time. You'd really have to swap receivers and see on which you can hear particular signals better with the same antenna ...

Re: Frequency in SDRUno and hardware drift apart

I haven't seen any digital problems such as described (I'm using SDRuno 1.12 with an RSP1). Based on my experience with my RSP1 I'd say the phantom appearance of a station where it shouldn't be can be because of input overload. Try altering the IF Gain setting. With the RSP1 at least the AGC control...

SDRuno suggestions...

I'm still a pretty new user, though I now know enough that maybe my input would be useful... Some suggestions to improve the control of SDRuno, based on my usage of version 1.12 with my RSP1: ⋅ The Offs (offset) frequency shown when Synchronous AM mode is selected seems to be be off by dou...

Great experience with PAR Electronics EF-SWL

I did some homework before buying the SDRplay RSP1 and landed repeatedly on recommendations for the PAR EndFedZ EF-SWL long wire (45 feet) antenna: http://www.lnrprecision.com/store/#!/EF-SWL-Shortwave/p/39885474 I mounted the box under the eave at the northwest corner of my house, and ran the wire ...

Re: How do I make my SDR wireless using a raspberrypi3?

A wireless interface would nicely resolve concerns of bringing lightning right into the computer system via the antenna.

Strange QRM

I ran across something on 10010 kHz that I haven't heard nor seen before...
