Cap multiplier is used to denoise the powersupply, not to stabilize it.
MY QO100 SETUP

Hi, I bought a red USB 2*relay PCB for SDR-Console with green connectors but the WIN7 can not detect the driver.
Any ideas ?

also this SW may could help you..

DD0KP Yes Atmel TINY45

Hi,
A simple ground isolated PC interface , ready now for digital modes ...
-
Hi,
IC735 is aligned, it was about 100 Hz off ...
Searching for FreeDV and KG-STV QSO now.

SV1BDS May be the AT tiny has no program
Hello Heiner, do you have the code downloaded from an existing device ?
-
Looks like the USB interface is made from an ATTiny45 , same as USBTiny programmer for e.g. other ATTiny's.
So perhaps George you can look into that direction?
-
Hi, yes the PCB has also 6 pins that maybe is the pins for programming. If Heiner has try to read the code that can be done if the security fuse has not burned. Else I buy another same one and try to do it myself. But I have to wait 2 months... TNX all !!!
-
Yes, that is the ICSP port where you can program it. But .... if indeed the ATTiny45 is put into 'USB' mode, it may be that also PB5 is used, that means that it can't be programmed 'normally', but you need to HV program it. (Google on it)

From the datasheet it even has better P/N performance than the Bliley, but it's square wave and that often may be a nuisance because of harmonics 'flirting' around ; -)
