    I have a DAB radio with firmware version dab-sermmi-FS2052-0000-0489_V4.3.17.EX24607-1A11. I get correct output on the terminal with 19200 baud if I connect a PC via a RS232/TTL level shifter to the TX line of that module. However, the verona module remains silent if it is extracted from the radio and powerd by a test-setup. Flashing dabp-fm-sermmi.ref.ven7_V4.1.14.32300-1 and dab-sermmi-FS2027-0000-0359_V4.2.11.38059-1B19 did not solve the problem. Only once I was able to get some output while I was fiddling with the module, but after the next power cycle it was silent again.

    My first guess was that there is some problem with power sequencing. So I changed it from the 1.2V supply coming up first to 3.3V coming up first, but it did not do the trick. Then I experimented with the reset line. Applying a pulse did not help either. I am wondering if there are additional pins that need to be connected, maybe some power on/off signal or something. Any hints? A schematic of a radio with verona module with complete pinout can be found here: http://www.radiowerkstatt.ch/downloa...att_schema.pdf

    Thanks morus - that's a really big help

    Now the problem.. where to get one of these 'odd' Venice tuners with the CS4344 / ATMEL AT45DB041D / KINO3 side-by-side on the PCB.

    All but the two Venice modules I have seen, have the 'normally' PCB layout - perhaps theses use KINO2's or the Chorus processor as opposed to this one with a KINO3?
    Both types of tuner appear to have the same pinout arrangement - however some of the onboard jumpers are in different locations.

    Do you think this would make a difference? - I assume Venice7 vs Veince7A

    Cheers, Richard

    Here is a list of radios with a Venice 7:

    Frontier Silicon Venice 7 (FS2027)
    - Philips AE9011
    - Sangean DPR-65
    - Sangean DPR-69
    - Sangean DPR-34
    - DUAL DAB4 (some versions have Verone/Venice 5.1/Quantek modules)
    - Pure Siesta Flow
    - DUAL DAB43

    There should be many more. You can identify a Venice 7 by the firmware version string. It should contain "FS2027". "FS2052" designates a Verona module which is a low cost version of Venice 7. It uses the same ICs and it is firmware compatible, but it is not shielded and has a different pinout. With some rewiring you could use a Verona module as well. Venice 7a is a low power version of Venice 7. Its pinout should be the same, but i am not sure if it is firmware compatible.

    Venice 5.1 ("FS2025") uses a KINO2, but the RF frontend IC FS1112 should be the same as on Venice 7/Verona. You could also transfer this IC to your Venice 7 module.
