Re: [Flexradio] New SDR1000 has arrived
Dave, if you import the database from the previous version, it will remember the PA gain settings last entered. If you install a new version without db import, it will install default values and you can run the PA calibration routine on the Setup with a dummy load. Doesn't take long and I still find it interesting to watch. So, there is no more gain typing needed. Mike - AA8K David Ackrill wrote: I've got it up and running this afternoon and checked it into my Bird Termaline dummy load and it calibrates OK. One question, the Gain results on the paper they sent is different to the default settings. Do you have to keep re-entering them? I noticed that, when I changed from V1.6.2 to one of the latest updates, the gain numbers were different. Is there a way to save the gain figures and do they get changed by the calibration routine? I've already calibrated against WWV on 10MHz, so almost ready to start making some contacts. What's the betting there will be a CME, I wont have any antennas up for VHF, and the HF bands will be knocked out?

Re: [Flexradio] New SDR1000 has arrived
If you have a dummy load, we will always recommend you just running the calibration routine as opposed to entering the data we provide. We provide the data as a historical reference and for those without a dummy load. You will get the most accurate results running the calibration with your radio at your location with your unique environment variables.

Dave (G0DJA) Dave, what kind of signal generator did you use to get a -130 dBm signal for your level calibration? I have an Elecraft XG-1 that I use for a -73 dBm signal.

Re: [Flexradio] New SDR1000 has arrived
Dave, I use my Elecraft XG-1 at 50uV to do the RX level calibration (this corresponds to -73dBm which is S9). I use either the XG-1 or wwv at 10.0MHz for the RX freq calibration. As pointed out earlier, the RX null requires a stronger sig than the 50uV supplied by the XG-1 so a second TX is a good choice for this calibration. Your situation with the noise floor so low sounds like something isn't right with the level cal. My noise floor typically sits at about -130dBm on 20m with med pre-amp setting. It sounds like you need to recalibrate the RX level against a known sig level, if I'm reading your comments correctly.

Re: [Flexradio] New SDR1000 has arrived
The RX null does not REQUIRE a stronger signal than -73.0dBm, but you will likely get a BETTER null if you do use a stronger signal. Just wanted to clarify that.
