I don't know anything about the codec (expect that is is not finished and does not work anyway), try asking on the mailing list.

Re: [Tetrapol-kit] Information about transmit

Hi, rtl-sdr does not support transmitting. There were some experiments with Raspberry TX, I don't know if it worked.

Re: [Tetrapol-kit] RPCELP codec
by P 16 Jun '17

The problem is RP-CELP specification for TETRAPOL is incomplete, even the bit order and meaning in voice frame is unknow. The goal is replace A/D converted in tetrapol radio which we posses and send well defined audio signals and sniff encoded audio on radio data bus. We already did this with analog signals using external audio input a got almost all bits solved, but few are still missing. This technique can be also helpfull to find out where radio does encryption and try to extract the encryption algorithm. We have already some usefull setups and few more informations which are not yet published, but lacking required hardware and time to do this.

Hi, RP-CELP codec is not finished, a lot of stuff is still missing to reverse- ingeneer. Implemented is only the first part of codec and even here are missing correct coefficients. We have some hardware but are missing digital signal analyzer (at least 34 channels at 32 MHZ would be required to get the data out of bus) and this seems to be blocker for now.

M9620 power supply
by kévin B 23 Mar '17

23 Mar '17

Hello. I would like to plug my g2 radio with a 4.8 V power supply. I plug the -/+ pins but nothing happens, no way to start it. I found the power pins with a simple voltmeter. I had saw this explanations: http://brmlab.cz/project/sdr/tetrapol/g2 but I don't understand if I have to use an existing battery for "id". I have 2 batteries that have worked but now empty. I would like to have some experts advices. Best regards.

Hi, Thank for this files, works great, i have the same results as you sent! But i yet cant understood with value of sync after demodulation, why is it "1, 0, 1, 0, 0, 1, 1" (7-bit)? I look in standard PAS 0001-2 6.1.5.2 (voice) and PAS 0001-2 6.2.5.2 (data) and there 8-bit sync with value 0, 1, 1, 0, 0, 0, 1, 0. >From previous question about IDE, now using QT, very user friendly, attach Makefile and go) P.S.

Hi, please keep mailinglist in cc, for others to find out. in tetrapol_dump is implemented SCR detector. It tries all 128 possible values and finds out wich one works. By design SCR is system constant for controll channels (CCH) and for transport channels (TCH) is broadcasted on CCH. I have attached small file with demodulated data and example outputs, hope this help a bit. It is CCH with system_info and few other messages.

Hi guys! You did really cool work with tpol. I'm also trying something with this one and you results is absolutely find for my! I have already demodulated signal and would decode it with your app/tetrapol_dump, is it real or i have to use binary only after your demod? Regards, Evgenii
