APCO P25 "Carrier Squelch (CSQ)"
มุมมอง 2.8K5 ปีที่แล้ว
CSQ: NAC F7E XTS5000 with a NAC of F7E hearing all traffic from every other NAC out there. It is truly the CSQ of P25.
I get 0.5 BER on my jumbospot pi zero w, I think its ok and its within green
This is a great video! I know you wanted to black out your programmed channels but I'd love to see how you programmed them. I'd also like to see how you connected your P25 personality settings with your channels. For example: I'd love to make sure I'm inputting the NAC or Tx Network ID / Rx Network ID correctly. I know most of them just use the $293. I want to make sure I have that inputted correctly. Thanks for a great video!
Well, all you need to do is put in the appropriate frequencies and NAC code for your repeater. the parts I blacked out were due to some local stuff that was going on and I wasn’t very willing to put some frequencies & tones out there publicly as we were dealing with jamming.
@@dev_ranger I totally get you don’t want to show the frequencies or names of the channels. But I’d love to see what’s greyed out and set vs. not set by the personality. In other words, seeing all the parameters that make up a properly composed P25 ham channel. Maybe put in fake inputs for the sake of the video just to illustrate the points?
@@ISkiBum1 i dunno maybe ill make another video at some point. i just make vids on stuff that im commonly asked.
Привет!! Хорошее видео!!! ХОтел узнать про DTMF и MDC. Мог бы рассказать?!
MDC и DTMF являются аналоговыми функциями, не связанными с P25. Они имеют множество применений, например, для идентификации и пейджинга.
@@dev_ranger огромное спасибо! Я только учусь, 73
Iv tried to add p25 to my hot spot but not a single server I tried will work still shows in red on pistar dashboard all code plug info is correct
brother, if you keep making videos, this channel group up fast
i wish lmao
@@dev_ranger if you have more videos, try to cover the most important aspect of those radios. p25,dmr etc. a lot of people have motorola and a lot of people join the GMRS frequency.if you want traffic, GMRS is the key
@@dev_ranger i am one of the BIG GUYS on GMRS on NY, I CAN HELP YOU SHARE YOUR VIDEOS IN OUR GROUPS. GOOD LUCK BROTHER.
Why not use the auto calibration at the ATSC freq? Set de Mode to SAM, choose Settings in the same window, goto the Cal page and click on auto. And it will calibrate to the center.
You CAN do that but a lot of people (myself included) haven't had the best experience with it. Sometimes it works, sometimes it doesn't.
@@dev_ranger Works for me in any case. 👍
Yesterday, my friend (XTS5000) and I (APX6000XE) tested the audio quality of P25 using a simplex VHF test channel. Here are our findings:- 1. The audio quality of P25 was superb. It was like TETRA. 2. My friend's radio was a second-handed radio bought from Carousell. He couldn't find a CPS for his radio so he only programmed his radio using FPP, which he couldn't set up talkgroups. 3. When both of us used the same frequency and same NAC code (i.e. 28C) for both TX and RX, both of us could hear and be heard. In this case, I used TG1 and I assumed his radio also used TG1 because the seller of XTS5000 didn't touch too much on the radio so I thought the TG setting left its default setting, which I thought was TG1. 4. When my radio changed to TX NAC 123 while remaining RX NAC 28C (and his radio still TX/RX NAC 28C, nothing changed), I could hear his transmission but he couldn't. This was expected because I transmitted at a NAC which didn't match him. 5. When I changed my RX NAC to F7E, I could receive his transmission (NAC 28C). This was the same as what this video showed. 6. We then resumed our NAC to TX/RX 28C, we tried and confirmed both of us could hear and be heard. I then changed to another TG (TG 65201) while remaining other settings unchanged. I found that both of us could hear and be heard, even though his radio didn't have TG 65201. My question is: What is the usage of talkgroup arrangement in P25 system? In our test, my friend could hear my transmission even though I changed to several different talkgroups which I believed his radio didn't have. The only parameter which affected transmission was NAC code.
TG mute isint set. So the radio was unmuting for any P25 TG on channel. It's a setting in CPS. It also could be that the radio isint setup for TGs. If you don't setup TGs, it'll hear anything. To Summarize: A) ensure TGs are enabled in the personality in CPS B) ensure your unmute settings are correct, in most cases the default is unmute for all
@@dev_ranger Thanks for your direct instruction! After checking with my codeplug, I found that I've originally set the "ASTRO Rx Unmute Rule" to "Normal Squelch" which means:- "The radio unmutes upon decoding a Network ID match. The radio unmutes even when it is expecting DES-XL but receives DES-OFB (see the DES-XL Tx Default field)". To achieve what I desired, I should set the "ASTRO Rx Unmute Rule" to "Selective Squelch" which means:- "The radio unmutes upon decoding a Network ID match and (either a Talkgroup ID match or a Selective Call.) If the radio is expecting to receive a voice call using DES-XL, but receives DES-OFB, then the radio will not unmute. The DES-XL Tx Default selection determines the type of encryption algorithm that the radio expects to receive when in this mode". Thanks! 73
@@dev_ranger What do you mean by the radio doesn't set up for TG? Do you mean there is no TG under a TG list and that list isn't being attached to a particular channel?
If the radio is not configured for TGs it would show that behavior… meaning the TG list is blank.

I have a question. How did did you change your Pi-Star dashboard with the black border. It looks much better in black then red. Thank you John KB4SGA
Configuration>CSS Tool I also have a browser extension that helps called: DarkReader My suggestion: Try dark reader first before messing with the CSS Tool. I changed off of normal pi-star about 2 days after this video was posted and haven't looked back. I am now on the W0CHP build which allows a little more customization. Hopfully that helps! -Dev_Ranger (6 Land)
Hopefully you will see this...I have programmed an XTS5000 before and have a pretty good code plug. So, for the most part, I do know my around these radios. Just bought another one after 2 years absence and somehow cannot hear any audio from the local FM repeater or my hotspot. Its got to be something simple. Any suggestions? 73

Thanks for your quick tip! How about the talkgroups then? I know P25 conventional system has talkgroup arrangement like DMR and TETRA. If I have two P25 radios sharing the same simplex frequency and same NAC code (for Tx and Rx), but with DIFFERENT talkgroups, will they hear each other? And if they won't, is there any TG number that functions like "all call" as in DMR system? If a P25 radio has a TG of 65535, does it act as an "all call"?
uhhhhhhhhhhh i just thow the F7E for everything RX that im unsure what the right NAC is nowadays. i made this so long ago, i'd have to try it myself. its also 1am so my brain is at like 1/4 capacity tbh.
As xts user i do satisfied alot with the audio rx tx performance of these Motorola's. But most of the time the baofeng still my go to radio, as it much lighter,dualband, easy to deploy. I bring my xts just for feel the tacticalness, and superb audio.
that hurt my soul to read...
I'm confused how you put a DMR ID into a non DMR radio?
So the HAM P25 reflectors utilize DMR IDs. It's kinda dumb but it's what everyone does unless you're on a private network.
My bit error rate on DMR never gets lower than +.2% to +.3% and that is at 0 offset. If I increases it to either more positive or negative it grows more positive error rate. At 500 Hertz offset my pi-star will not recognize I’m transmitting. So it may not be possible to hit 0%. That is my MMDVM_Dual_Hat for Pi GPIO hardware.
you will always have some % of BER, you just want it as low as possible. anything below 1% is great. when it's higher than ~1.5% the Rx station can definitely tell as the audio becomes distorted. BER will increase when the front-end of the MMDVM board becomes overloaded. try to reduce power to minimum that your radio will go and set the Rx offset to +100. if that doesn't work try to gain some distance. anything higher than 300 on the Rx offset normally will not work.
Great feature for when you either don't know the NAC or when scanning a network with multi-agency (multiple NAC's) Have used it on my APX works a treat.
This works for our Canadian OPP since i don't have trunking setup just the tower repeaters about 9 frequencys an couldn't hear them so NAC code listed on radioreference didnt work this does using F7E now thanks
yeah! its all i use now for RX as its simple to remember and works.
i would highly programming on a x32 bit windows computer instead of using a x64 bit computer, old computers work best with old software even though ASTRO-25 PORTABLE CPS was made both for x32 and x64 bit.
I actually disagree, never in 5 years have I had an issue with X64 systems on the ASTRO 25 CPS (mobile and portable). I've got a few portables & mobiles and I program them all using either a USB programming cable (eBay knock off) or an OEM cable with a DB9 to USB converter on them. I've Never had and issue and never heard of somebody having issues with it (regarding bricking or something of that sort). Most common issues tend to be with drivers and fake cables not working properly. It truly is personal preference and/or what you have on hand.
Hi thanks for the video, I am new to P25 Amatuer can you show me the correct way to program freq and NAC code. I feel I am missing something here
