Will the HQCT module be able to be driven by a pda? I've got an Acer n311 pocket pc. It has an usb-host connector. So I was wondering if it could be possible to plug this radio to it?
Thank for your answer.
Hello,
for me the most problem is the connection for sound. I want to install my hqct in the front, but my pc is in the back of the car.

As long as the PDA actually has a USB host, then yes. You may have to port the software though.Originally Posted by Clio

Hello,
please help - could I use this antenna cable?

Is this fakra the right one you can see in the picture? I don´t know how it´s called in Germany and can´t find a shop where to buy, because I didn´t know, what I have to search.
Thanks for your help

nice that you are doing an RDS decoderOriginally Posted by aeroanderz

I can't 100% imagine your problem... i don't have any 0A and 0B sequences here...
I have looked inside EN50067...
First question:
Do those radio-broadcast-nerds mix up Type A and Type B ?![]()
Method A works for you ?
(Or are you talking about AF type 14A groups (for EON) ?)
And finally:
What does the TEF inside the HQCT with RDS error correction ? (How many bits does it correct ? IMHO the TEF is able to do error correction...)
(I noticed although with a good audio quality and strong station 50% of the RDS Blocks contains 1 error or more - not with the HQCT but with a hacked HU and a SAA6588)
Not easy to tell, but it should be OK. Only problem to be 100% sure is that I can't see the fakra connector's connecting side!Originally Posted by Ti-ejtsch
The other side is a so called "volk" or iso connector, the second-most used connector after motorola I think.
I'm curious about the two 5V power inputs... from what I understand, the 5V on the USB cable supplies the power to the USB circuitry (PIC) while the molex supplies power to the tuner. The two 5V inputs do not appear to be tied together based on the board layout. I'm running a nonstandard computer (HP eVectra) and it only had one molex that goes straight to the 3.5" HD. I guess I could dig up a molex Y cable and hook that in, then I'd have to find a way to get the cable out of the case (not too hard I guess...). Can I hook the 5V on the molex up to the USB 5V on the board (wire jumper)? Then hook the 12V up to the car power? I'm thinking that might not be such a good idea, since the car power is so dirty.
Also, it seems like a lot of people are getting frustrated with cabling issues - for USB I just cut up a cable and soldered wires to the bottom of the board, same with audio (3.5mm stereo plug on a cable). I plan to do the same with the antenna cable. It won't be a perfect 50ohms, but this is relatively low frequency, and it's receive only, so I'm not too worried. But this way, the original connectors are still intact, so if I decide to use those later, just unsolder the wires on the bottom and plug in the connectors... There are still connectors on all the cables (so I can take out the board)... just not on the board.

The 5 V power from the USB connector is NOT used at all, the module is powered from the Molex only, both 5V and 12 V.
You could power the HQCT from the car power provided you stabilise it a bit, dont forget that car power can get up to 14.5 V, and it is as you say 'dirty'.
If you hook up a stabiliser that generates 5 V (100 mA max) and 12 V (100 mA max) you're off. There is an 8.6 V stabiliser on board, this means the 12 V input can drop to say 10 V and still work OK.
Power inputs are also filtered on board with coil and capacitor.
