DSD+ Decoding Polarity Auto Detect

[Muxlow]

Was the command removed from DSD+ to enable Polarity Detect at startup? cant find anything in the notes file

I have a streaming pc running dsd+ on a dmr system and the pc reboots once a week. I dont hear any voice coming over the stream unless decoding polarity auto detect is enabled is enabled.
With the latest updates when i boot dsd its not checked and have to manually click the tab to enable it, i think on the older version there was a command line option of -P or -p to enable this at startup but that dont seem to be working now. Anyone know what the new command is to fix that?

The option is in the Decoder options in the DSDPlus window --

If you read my post i did mention i have to click that each time the program starts. I was sure in the older versions they had a command to type in that it would auto turn that on once DSD loaded. I dont want to have to go to that computer and click the tab once a week

Older notes says adding -P or -p to the command line would enable it but that dont seem to work on the current version

Maybe the setting isn't being saved in the BIN file? Email has been sent to DSDPlus

@GTR8000 pointed out all the keyboard shortcuts that got axed and -P toggle signal polarity was one of them.

I received an response from DSDPlus to the email I sent them the other day concerning this --

 

[Muxlow]

It sure isnt working on my setup then using a rtl dongle. Ill just go back to a older version for that computer then and problem solved

Decoding polarity auto detect is not checked on startup for me also.
I manually select it myself now at each startup.

 

[Muxlow]

Rather then making a new topic on this same issue ill just toss the AED on this one and revive it

With the latest release of DSD+ V509 i still cant get the auto polarity detect to stay enabled. EVERY time i close out dsd and reopen it i have to click that dame setting before it will start decoding anything.

Here is my bat file. All i would like it to do it enable auto polarity detect, and combined cc/vc monitor on startup

:FMP24-CC.bat:

Start FMP24 -i1 -o20002 -g36.4 -b-12.5 -T1 -P0.1 -f858.6375
timeout /t 3

:CC.bat:

Start DSDPlus -rc -i20002 -P -o2 >>CC.log

 

[slicerwizard]

I'm curious - why do you need auto polarity detection? FMP24 will never feed DSD+ an inverted signal, so why the need? How are you getting FMP24 to feed DSD+ an inverted signal?

 

[Muxlow]

Just have a dongle and a bat file.
Not sure how its inverting the signal at all? Using the commands uptop there and no matter what it wont decode anything at all until i click auto polarity detect. Once i do that it starts to decode the audio. Was never an issue until about 5 updates ago or so whenever that -P command was removed.

Have to do this on P25 trunking and DMR. Computer reboots and comes back on, dsd fires up with auto start and everything is fine and good but no audio is passed until i click that tab back on

Start FMP24 -i1 -o20002 -g36.4 -b-12.5 -T1 -P0.1 -f858.6375
timeout /t 3

:CC.bat:

Start DSDPlus -rc -i20002 -P -o2 >>CC.log

Just out of curiosity, why do you have the FMP24 bias tee enabled? Do you have a device installed ahead of your SDR that requires power?
If so, what is that device? What is the actual frequency of the DMR system that you're monitoring? Can you post the spectrum display
from FMP24 of the DMR system while the signal is present?

Think i fixed the issue
Iv been using the same commands for ages and just happen to look at the dos type window and it was saying such n such command is no longer needed. So started removing stuff then for the hell of it decided to download the base files and look what the default setup is.

Copied that over and poof.. seems to be working now. Think it was specific to the -T -E -Pwav (whatever them things do)
Gave DSD a reboot and now its decoding and im hearing audio without having to go click the auto detect box so.. yay for having an out of date bat file apparently.

Incidentally, I think FMP24-CC.bat goes along with 1R.bat in a single dongle configuration.

FMP24-CC.bat : CC.bat (first instance in a dual dongle setup)
FMP24-VC.bat : VC.bat (second instance in a dual dongle setup)

If you're running two dongles, great. Otherwise, you likely should be using FMP24-CC.bat and 1R.bat

One setup is a single airspy
couple others (all different PC's) single nootel whatever dongles.
airspy is for a vhf p2 system with voice following (all encrypted so no audio needed)

other 2 setups are for conventional dmr repeaters.

1 is scanning 2 dmr frequencies and a analog channel (fire paging frequency and 2 dmr tac channels sending to a feed)
Been working fine for the past few years other then having to click the auto polarity detect, but since changing the bat file now its working how i want it to. So dont think i need to change anything? If it works it works type deal

Do whatever works for you. They essentially do the same thing. The main difference is that the default CC.bat uses -rc, which sets it as the dedicated control/rest channel decoder. 1R.bat does not. For the next guy or gal who comes along, just starting out, it's just best for them to know/use the proper pairing.

FMP*-CC.bat / 1R.bat (single dongle)
FMP*-CC.bat / CC.bat (dual dongle, control channel monitoring)
FMP*-VC.bat / VC.bat (dual dongle, voice channel following)
