In my experience, the more - the merrier.

It seems to be really numb like it needs a boost key?

It seems to be really numb like it needs a boost key?

I don't understand any of that. Please explain.

 

[radioopperator]

2025-145 The receiver part of the software seems to be really weak even if set to 100% gain.
That causes the program to go white screen and search for channels. I'm 4Miles from P25 P1 site and this version drops out a lot.
and I can see the antennas.

Portable version 2025-92 I believe seems to be way more stable and not loose signal for CC or VC like the Cygin version.

If there is no buffer delay in the portable version than the receive code is way better in portable for me?

There isn't a way to use a separate receiver spectrum analyzer like DSDPlus is there, so we can, tweak signal real time and see it on screen live is there?

Just what I'm finding.

I get best results using 0 (automatic) gain when using RTL directly. I recommend it in your case. If you can see the tower, any gain may be too much.

If you are talking about DSD+'s FMPx, I don't believe it's compatible with DSD-FME. You can use SDR++ for trunking and most anything with DSD-FME. Also PPM is very important. Most RTL devices don't work well with simulcast systems. YMMV.

 

[radioopperator]

I have pretty good luck with trunking using the 2083 chipset?

With SDR++ how do I port the dsd-fme to work with ++? so I can see real time the freq spike and the PPM?

I use this with portable version: set "options= -ft -i rtl:0:771.00000M:0:5:12:0 -T -G group.csv -K multi_key_hex.csv -P -N -Z 2> log.ans "
Direct to the SDR.

 

[ki4hyf]

To use SDR++, try:
"options= -ft -U4532 -T -G group.csv -K multi_key_hex.csv -P -N -Z 2> log.ans "
TCP audio is optional for input. "options= -ft -U4532 -i tcp -T -G group.csv -K multi_key_hex.csv -P -N -Z 2> log.ans "

Be sure to setup RIGCTL and optionally SINKS if using TCP input.

I got slammed by one of the "experts" in another group for saying that. It's true regardless.

I have a three year old version of DSD-FME Aero Addition for Windows. How do I upgrade to the latest version? I haven't played with this for some time now.

Looks like your not getting the mpg that the rest of us get.

Myself, as well as many others have used everything from cheap china dongles to more expensive stuff like Airspy, HackRf and Sdr Play and are decoding multiple simulcast sites/systems without any issue.

I got slammed by one of the "experts" in another group for saying that. It's true regardless.

Pretty sure that was because you claimed something like the dongles don't have the hardware to deal with simulcast when its actually the software that handles it.

Why do the the SDS handle simulcast so well?

Because the SDS scanners utilize SDR technology which is a way of performing radio signal processing using software instead of traditional hardware. The I/Q technology is how the SDS scanners capture and process radio signals and enabling it to decode digital signals even in challenging conditions like simulcast systems.

Yes, I just downloaded this, thanks for the link.

The older version I have is "MBElib 1.3.2 / AW (CYGWIN) / 2025-21-g42cb14b

The one I just downloaded is "MBElib 1.3.4 / Aero Build / AW (20240601)

Not sure what the differences are between the "Aero Build" and the other.

 

[FLLJack]

Amazing. Just did the automated DSD-FME cygwin install on Win10 and have to say this was beyond easy and it actually works right out of the box!! Took like 5 minutes to install. Only caught some garbled audio so far but considering this is my first attempt at digital decoding with an SDR that has ever worked I am seriously blown away. This is truly amazing work you have done.

To use SDR++, try:
"options= -ft -U4532 -T -G group.csv -K multi_key_hex.csv -P -N -Z 2> log.ans "
TCP audio is optional for input. "options= -ft -U4532 -i tcp -T -G group.csv -K multi_key_hex.csv -P -N -Z 2> log.ans "

Be sure to setup RIGCTL and optionally SINKS if using TCP input.

I'm doing something wrong keep getting socket refused.

 

[ki4hyf]

Please post your actual "options" line and a snapshot of SDR++'s RIGCTL and Sinks options.

Ok what is the SINKS option?
I tried your stuff in the portable version:
o use SDR++, try:
"options= -ft -U4532 -T -G group.csv -K multi_key_hex.csv -P -N -Z 2> log.ans "
TCP audio is optional for input. "options= -ft -U4532 -i tcp -T -G group.csv -K multi_key_hex.csv -P -N -Z 2> log.ans "

Tried both of these and in the CYGWIN64 side I tried: dsd-fme -ft -U 7356 -i tcp -T -G group.csv -K multi_key_hex.csv -P -N -Z 2> log.ans I get an error saying 127.0.0.1 with the used port number is activly refused by the machine? I'm wondering if its a fire wall or virus checker stopping it from running?

I will try to post screen shot in a bit.

 

[radioopperator]

What is SINKS not fermilure with that term?

 

[TheButcher]

Or spellung.

Source and Sink. Both opposites.


Source is where you get something from and a sink (think heat sink) is where something goes.

Two parts, Rig control and Audio. The Sink is to do with audio.

I can't help you if you refuse to help me. See: DSD FME

I asked you to use -U 4532, but you used -U 7356. It may be that you had some reason for using port 7356, so that was one of the reasons I asked for a screenshot of your rigctl settings in SDR++. I mean this in the nicest way possible, but at this point, I believe a scanner is your best option.

 

[radioopperator]

Sorry busy, I tried all the stuff in the example file to include putting the 127.0.0.1 in the string and even 127.0.0.2 along with a bunch of port numbers too. I'm working on a new computer build that has NO virus checker on it to see if its that since its saying refused by machine. So I think firewall or virus checker or both? Its on windows not Linux.
