Working SSTV via satellite

I've been using an RSP2Pro/SDRUno 1.31 together with MMSSTV with rather good results on the "Remembering W5LFL" event currently running on the ISS but have run into a few issues where I'm looking for some help or guidance. 1. It's been very useful to run the SDRU recorder during a pass so as to repl...

Re: SDRUno 1.31 with Windows 7 issue

I've been suffering a problem very similar to this on an HP8440p Elitebook Pro laptop 2.4GHz-I5/Win7Pro for about 2 years and the only way I've found to fix it is get another computer. Which is what I've just done, having fallen into a sweet price on another laptop. My problem started soon after the...

Re: Scanning the 2M Ham band

Thanks Andy, and to all who replied to my previous post. I haven't had much chance to experiment further with the scanner, but to answer a few questions put to me: - OK, I get it that there's a block DFT done on the available IFBW, so I take it the scanner window will seem to be stuck while it's act...

Re: Scanning the 2M Ham band

I'm having problems as well in trying to scan anything in the FM/VHF band. Tried a freshly-booted instance and it works ok on the AM preset. Then selected the AIRBAND preset and SDRUno crashed. Re-launched SDRU and tried to set up a custom preset with: Main decimation = 1 (SR = 2000000, IFBW = 1.536...

Re: Using SDRplay RSP2 pro as panadapter w/Kenwood 830s

Remarkable that your 830 is still on the air! I had an 830 in the '80s before eventually trading it in for an 850 which is still my primary HF rig. To your point, I've connected the IF Out RCA tap point on my 850 directly to the Ant1 input of the RSP2Pro without any special switching or isolation wh...

Re: Will the IQ recorded data store as .wav file format?

Would you please give more detail on what you mean by "noisy audio"? Is it noise/audio artifacts that you're hearing that weren't there when listening to the live stream while making the recording, or are you not hearing anything but random noise regardless of where you tune the VFO or set the demod...

Re: Can you use the SDRPlay2 as a pan adapter?

To Gbujold: Connect RSP2 port A or B via a short coax directly to the TS850 rear panel RCA socket "IF OUT 1". Taking into account the recommendation from DK7OB to swap I/Q channels (thanks for that), set SDRUno: Main window OPT - Swap I/Q = enabled Sample rate = 2 MHz. Decimation = 8 (this combinati...

Re: Can you use the SDRPlay2 as a pan adapter?

I don't know the TS590 but according to the user manual, the DRV port can be configured as an output (DRO) of the 590 TX to drive an external linear amplifier, or as a split of the RX received at the ANTx ports. The assumption here is that you've configured your radio with the DRV port as a split of...

Re: Excessive CPU usage

To update on this thread, the offending HP laptop has miraculously and of its own accord, "come good". Same kind of situation as in F1BJB's reply. I've not done anything that I can put my finger on except that the Win7 has been updated a couple of times with the most recent KB security and .NET upda...

Re: Can you use the SDRPlay2 as a pan adapter?

I'm using an RSP2Pro as a panadapter on my TS-850. Simply connect it to the "IF OUT" RCA jack on the rear panel. I don't know the details of the TX mixer string in the 870, but the 850 string has inverted spectrum in the 8.83 MHz IF. It's not a great drama, you just have to remember that signals bel...
