HQCT Module (new thread following HU RDS/RDBS)

[Diogenes]

Can the code be read out of this text file and put in the ini file so RR can read it ?

the code can be read out of the text file but RR has no provision for reading it in. Guino used my code and modified it adding RR communications (basically), when i mailed him the last version of HQCT he had his RR version out, since he is on the road this week it will take a bit longer before these last improvements are in the RRHQCT.
When using HQCT software you can hit the 'Read EEPROM' button', wait a few seconds (watch the level, when it is changing rapidly again) and then hit the 'Apply' button (check if the field above the 'Read EEPROM' button has valid data, ie not all zeroes or A9) from then on the program will use the correct constants for that particular tuner module, it should give a difference in reception. (The very last issue of HQCT software does it automatically, but you can still perform the manual sequence, this very last version also has the seek buttons for AM)
I am preparing a post with more data and explanation but i need a couple of 48 hour days to get it in a presentable form.

is there a list of which frontend dev's have one, and which frontends have the software implemented?

[Diogenes]

Is there another internal volume control which I can lower slightly ?

the tenth control byte in the array next to 'Send Settings' should read 00, bits 3 and 4 of this particular byte control the radio signal input gain of the audio controller (see attached docs)
I do think however the problem is caused by wrong tuning constants

Sounds as if the usb-cable is not correct.

The radio should be detected as a HID device (2 are seen in device mgr) see the screenshot.

Yes there was a problem with my cable. After cutting some usb cables and soldering few things, the unit can be detected now.
I will try it in car with rr this week end.

Sorry if this has been covered, but wasn't immediately apparent:

If I want to use a laptop-based system with this, it seems like I'd need a USB cable with a split up "pinout" end for the HQCT for the control, a modified power line to fit the molex connector... what about the audio - would I need to construct a cable with a mini phone jack if that's what my sound card takes?

Hi,

Follow the following schematics for connection.
Hope this helps

basicly i need another 1 of the connectors for the coax to the smb plug anyone know where i can get one?

ta

I got all the parts I need from RS components http://rswww.com/ in the UK, they stock a good selection of male and female SMB connectors to make your own extension cables as well as some pre-made cables. You can also get the 2x5 IDC sockets and ribbon cable to make your own USB conection cable to attach to you motherboard header.

Now all the cables have been made just need to install it.
