Hi - now the "Medium Wave Offset Atlas" with 9kHz channels has been finished and can be dowloaded for free

I am using N3FJP logging software. While using the spotting portion, I select s contact and my radio and the SW2 software go to the proper frequency; however, the SW2 software does not go to the

I just installed SDR Console 2.0.26 and I like it so far; however, I have 2 big questions: 1. Is there a PTT button, not including the mouse enabled one in Transmit DSP Window? The Space Bar

... on medium wave, it is in the millihertz-range. All my screenshots had been made from SDRC V3 recordings. Good luck on this & 73: Nils, DK8OK Am 31.01.2021 um 16:43 schrieb Pete: -- dk8ok.org

Nils, I am curious as to how well a recording using my TXCO/GNSS FDM-S3 would resolve using SDRC V3. Pete

Hi - with the new Elad FDM-S3 and its OCXO/GNSS-stabilized clock, I did a 24h recording of the whole medium wave band on January 19, 2021 in Northern Germany. Free software SDRC V3 enabled me to make

You probably knew this already, but the up/down buttons on the mic are connected such that pressing 'UP' generates a short circuit to ground on the appropriate pin of the connector. Pressing 'DN'

... thanks, Rich. The mainboard is Z390/AORUS PRO. And the model is a tailored Kenko model by Silentmaxx, about two year old now. 73 Nils, DK8OK Am 30.01.2021 um 16:13 schrieb Rich O.: -- dk8ok.org

Nils, Thank you for the information. I assume you are utilising the native USB/3.0/3.1 ports on your W10 PCs motherboard. Without advertising, can you share the motherboard or PC model. 73

Definitely a Ryzen 9 5950x with a X570 mobo. 73 Francesco, IN3XZP

Thanks all for the replies about HDD, I've also had some additional info off list and these recent internal SATAIII HDDs do sound up to the job. I'm going to save a few quid and get a pair of Seagates

Hi Nils, I have had no problem recording to my 12TB internal Hitachi HDD, with the S3 at full throttle. Interesting that you managed it through USB3.. I must try that here...

After the discussions last June/July, I changed over to using a dedicated Morion MV89a for the DUO, with a very long time-constant PLL to keep it on frequency and no buffer, just a good attenuator to

Andy, John, Neil and David. Many thanks to you all for your help. The problem is solved - it was the 10MHz reference source. Mine also comes from a distribution amplifier - modified

The issue is the 10MHz ext ref. as mentioned just now. But here's a set of measurements at 28 - 165Mhz http://www.g4jnt.com/DropF/duo_spurii.zip Andy www.g4jnt.com

I think you've hit the nail, John PSU is blameless, but when I removed the external 10MHz input, all but a very small pair of sidebands went away. I was using the wideband SpecAn, so couldn't

Hi - let me share my experiences with "big data": * I am using WD Duo Book external HDDs of 20 and 28TB capacity. * They are connected via USB3/3.1 to a W10 PC. * The connection are supported by one

When I replied to Chris , I mentioned it rang a vague bell. Neil seems to have similar recollections . Have you tested for spurions without the external 10MHz reference ? Run on a battery supply ?

Hi Andy Can it be some internal Low power swiching regulator? Do you see same behaviour at different fundamental frequency? David IW5BNL

The mystery deepens : Aeroflex 7100 Digital Radio Test set, Input 22dBm via transverter interface. It's clearly not alias related. This plot was made at 144.3MHz dial freq with audio injected into
