Re: [Flexradio] 1.18.3 Noise ?

From: Dan Scott dscott1...@comcast.net Date: Wed, 30 Sep 2009 Time: 15:14:15 When connected to an antenna, the Noise Floor of v1.18.3 is always 2db to 3db higher than that of v1.18.2. Also another radio was used to verify if the higher noise floor was just a metering difference or a if 1.18.3 was imposing additional noise. The result is the FT-100 could receive SSB, CW, and digital which the SDR1000 with 18.2.3 covered up with noise. With 1.18.2 the SDR-1000 easily out received the FT-100. I've just fresh-installed 1.18.3 for use with a SoftRock. I too noticed what seemed to be a higher noise floor than I'd previously experienced, but I don't have any hard numbers for comparison.

Re: [Flexradio] 1.18.3 Noise ?
I forgot a couple items: 1. the noise is between from 15-meters through 30-meters. 2. I did a cold start up test too. Shut everything down for 12 hours and tested immediately after bring everything back up. I normally leave the radio powered up because it has a difficult time getting onto frequency. It take a few power cycles to get the SDR-1000 on frequency, but once on, it stays on frequency. Dan Scott wrote: I've been fighting what I thought was an RFI problem.

Re: [Flexradio] 1.18.3 Noise ?
Did you perform a full re-calibration of the SDR-1000 with a new database after the upgrade to 1.18.3? This is required for the SDR-1000 for every software upgrade. -Tim -Original Message- From: flexradio-boun...@flex-radio.biz [mailto:flexradio-boun...@flex-radio.biz] On Behalf Of Dan Scott Sent: Wednesday, September 30, 2009 5:14 PM To: Flex-Radio E-Mail Reflector Subject: [Flexradio] 1.18.3 Noise ?

Re: [Flexradio] 1.18.3 Noise ?
OH.. It looks like I only set the frequency in the calibration tests but blew right past actually hitting the Start for each of the 3 tests. Thank you Tim for asking! I did a lot of work for a stupid little thing *sigh* The good thing is I finally got around to swapping out my 30Amp PS for the 50Amp, re-wired most of the 12-volt stuff to Anderson PowerPoles and connected the power distribution strip. I feel projects are like wine and need to be properly aged (my XYL has a different idea about projects, but hey they're my projects!). I guess this project finally came of age.

Re: [Flexradio] 1.18.3 Noise ?
Dan, Just a tip, I had the same symptom (off frequency at power on needing to cycle power several times) several years ago. It was the 200 MHz oscillator which started slightly off frequency about 50% of the time. It took me a long time troubleshooting and the evidence came when I replaced it with a 10 MHz pin compatible oscillator recovered from a junk computer card (and selected the PLL multiplier to 20X). I ordered a replacement oscillator from Flex and the problem was solved. 73 de Ignacio, EB4APL - Dan Scott wrote: I forgot a couple items: 1. the noise is between from 15-meters through 30-meters. 2.
