Softrock sometimes not connecting after boot up

 

I've had this issue off and on ever since setting up the Ensemble RX II a couple of months back.? I can't trust that it will be running, so the first thing I do when in Win 7 is check CFGSR to see whether or not the unit is connected.? About half of the time, it isn't and the only way to remedy is to reboot.? After one reboot, most of the time it then shows connectivity but every so often it will take two reboots.? A remedy for this would be welcome.? I've tried different USB ports and in fact it is plugged into four plug hub right now. Thanks.? Jon

Playing USB is how I've rectified such problems.
A common thing is a Keyboard/Mouse RX. Put that on a hub and often the problem is bypassed.

Good Afternoon Jon,

Your reboot issue may have an RX II hardware problem cause. The HF RX II you recently sent to me for conversion to an LF RX II did not have the right and left end connections of the SI570 properly soldered to the appropriate circuit board pads, in fact one connection was not soldered at all. This could result in that connection to the Si570 being heat sensitive and sometime making enough contact to the circuit board to "work".

Wow, wasn't aware of that.? Maybe that's why the receive was weaker than the other HF one I use now.? However, I'll put the SI570 under the magnifier and double check to be sure.? Thanks!

Hi Jon,

On each end of the Si570 are three tabs. Only the middle larger tab on each end of the Si570 is to be soldered to its circuit board pad. Solder bridges between end tabs on either right or left ends can cause communication problems with the Si570 and USB communication problems.

Also keep in mind that with the LF RX II receiver coming back to you the Si570 clock frequency is divided by 16 in the SDR setup.
