Re: [Flexradio] blown SDR-1000 final opamp

I have accidentially made all sorts of mismatching the output from my OPA2674 and never have blown it. Running audio with Ozy/Janus and more than 1W rf-output. Maybe the reason is that you have overdriven the audio input. Gerd, DJ8AY -Original Message- From: [EMAIL PROTECTED]

Mack, one possibiltity is: use a router or switch which is always connected to the mains and the network cable with the computer that is used with your SDR. Use a master/slave power panel where the computer is the master and your SDR one of the slaves. With Lanstart or a similar program you

I believe that it has been pointed out that those people who are interested in multiband image compensation for the SDR1K do not expect an automated procedure but would do it manually. A signal for every band should be available for most of us. 73, Gerd DJ8AY -Original Message- From:

[Flexradio] DC-Hump with SDR1000

I am using the SDR1000 with Janus/Ozy and have minor problems with the hump: The hump is normally not visible. It is mainly visible when switching to a different band for a short time and decreases within 1-3 sec below the noise floor. This looks like a capacitive charging/discharging or a loop

Hi Bill, besides the fact that the A/D-values from the pa are not read with J/O you need only 1 usb-cable between computer and SDR. That is the main reason for me to use J/O with the SDR1000. Therefore I can use the parallel port for my printer again. 73 Gerd -Original Message- From:
