SmoL,
The hardware design is completely finished on the HQCT. It uses one of the best available tuners and audio processors. The audio processor is designed to integrate everything into one piece of silicon making design a lot easier. Thats why it has so many inputs. Though I never use the software on this forum. I connect mine to my PC through i2c using a Philips Dual Single Master interface I built from a schematic they provided. I use the Philips control software too, which in my opinion is the best because it has all the options that radio nerds like myself love to play with.
But I will say, the Silabs unit is really nice in terms of performance. Connect a decent antenna and you are good to go. It's designed as a high performance receiver in low power portable applications with varying receiving conditions. For it's size and low power requirement it's quite amazing what it does. But again, the USB FM radio is designed as an evaluation vehicle to evaluate it's performance, not an end user product. It seems to me like it has the performance of a high-end end user product, but the software does not work in my situation, and the stock antenna isn't the best in weak signal conditions.

I agree you cant expect good reception with the stock antenna, one you connect it to your car antenna though it is a totally different sotry. And sorry but if HCQT is finalised then i willnot buy it. I just see to much user unhappyness on the thread for it to be swayed to buy it...
The HQCT also does not support audio-over-usb, which is a big drawback.
Therefore you must mount it near your pc, or run an audio cable all the way back into your soundcard. Not ideal. I much prefer SiLabs approach.
You can mount the USB unit right next to the antenna and run USB the rest of the way. A much better way to deal with tiny analogue signals in an electrically noisey environment!

Ive asked when such an HQCT version would be available (audio-over-usb) and they said 'its not in the works' (read: a year or more, if ever).
i think i'll stick with the silabs, at least its a name you can trust and not homebrew, so even thought its r&d the support is still there
Is it just me that gets no sound after changing frequency in radiator. I am using radiator and the DLL that you can find in a link to somewhere in this post. It works fine until you try to change the frequency. Then you get no sound and radiator freezes when you try to end the program. If I kill the radiator.ini file I can use the program again.
The silabs device has good reception in stationary use. Havnt tried it in the car yet.

hi evryone, just wantd to share my experience. I am using silab usb fm on my car nothing special just striped wire from car antena connectd with silabs antena and reception is close to perfect. i used it for awhile without connectng it to car antena it was almost useless because i had to hola it to get reception. Im using it with RR n radiator with digital fx skin. No rds on skin neither on radiator. Reception minimally changed with speed, id say 10%. I am very happy with my buy and install. thanks for the guidance guys i wouldnt b enjoyn it without this thread. keep up the gud work. HOPE TO SEE RDS ON ME RR!!!
How do I get hold of these in aussie? Sydney to be precise.
