[Android Head-Units] HMT06:
Hello,

I think that the google translation is not good and there are some mistakes. I try to answer you without translation.

I tested the two versions at the same place in my car. The reception was really better on weak signals with 1.9.117 version.

It's as if the muting in a FM receiver was set too high!

I compare the last version 1.9.118 with DabPlayer -C2-H3.06 and DabPlayer C2-H3.18.18. After a complete scan, the number of stations found is equal but the audio cut with 2 bars signal but it's a little better with your software.

Dab player decodes station logos, your software only takes a few. But it's possible too add the logo in the station list with a long press of the finger, it's just longer.

Finaly, DabPlayer launches a scan on the sid of the current station when the signal is too weak.

I'm really sorry that I can't send you a raw recording but it doesn't work. After typing 7 times on version 1.9.117 nothing changes!

I attach below a very interesting conversation found on a French forum which explains how the following service works and how in France the FIC and FIG information (fast information channel and group) are not transmitted by French transmitters except on a single transmitter in Paris. hope the google translate will be good

FIC and FIG data are defined in the DAB+ standard.

In particular, we find the use of FIG0/21, FIG0/6 or FIG0/24 in the technical standard ETSI TS 103 176 Rules of implementation; Service information features in chapter 5 relating to the monitoring of radios from one mux to another, from one block to another or also between DAB and FM.

FIC and FIG Fast Information Channel and Group

FIC and FIG data are defined in the DAB+ standard.

In particular, we find the use of FIG0/21, FIG0/6 or FIG0/24 in the technical standard ETSI TS 103 176 Rules of implementation; Service information features in chapter 5 relating to the monitoring of radios from one mux to another, from one block to another or also between DAB and FM.

the FIC structure is shown in this worlDAB document:

https://www.worlddab.org/files/document/file/3923/2._JRTV_2017-DAB__System_Structure.pdf

the definitions of these data can be found in the worldDAB glossary:

FIC :arrow: Fast Information Channel

The FIC is a non-time-interleaved data channel with fixed equal error protection. In particular it is used to send the DAB Multiplex Configuration Information (MCI) and optionally Service Information and data services.

FIG :arrow: Fast Information Group

The FIG carries the following parts: Multiplex Configuration Information (MCI), Service Information (SI), FIC Data Channel (FIDC) and Conditional Access (CA).

we were led to talk about this FIC data on the forum in the thread of the two metropolitan multiplexes from February 7, 2022 because this data contains the information for monitoring services from one mux to another, when the reception picks up. This signaling is optional, widely deployed in Switzerland in particular but not at all in France currently.

the free DAB Player PC software (combined with an SDR-RTL key for less than 20 euros) makes it possible to recover these FIC data over a period of time (one minute is generally enough to recover everything largely)

We can already see if the different FIG groups are present in the FIC with DAB Player, in the DAB-info, FIC and FIG Statistics section...

They are all empty in Paris on all the multiplexes... except on the extended 11B Paris where we have FIG0/6 data...
