If you are 'ok' with a manually-tuned low-cost preselector, it might be worthwhile to have a look at the BCC (Bavarian Contest Club) preselector (design dated from ca. 1998). There is a brief

Hi Paul, This is a test to see if JPG pictures come through in an email on the groups.io site. Here is a spectrum display of the AM broadcast band at my QTH in Phoenix, AZ. I get ADC

Hi Paul White, I suspect that there would not be enough demand for the special filters to warrant Elad’s financial investment in the project. The current Elad ham band filters, while

Sounds like an opportunity for someone to design and make filter boards for other specific uses. I'd like a narrow one for 136kHz for example. Neil G4DBN

Paul I have requested a few months ago new filters to also cover the main broadcast bands that swl users can make use of. Also a dedicated am 520-1800 notch filter Paul EladUSA

I find the markers in the IF window more useful than those in the main window. If you set the averaging in the IF window to 60 or 100, then the numbers are smooth enough to use for sun noise

Hi, Clint Isn't it a little disappointing that the available filters are designed for the amateur bands only? I wouldn't have the skills to build on the unpopulated boards.

Ivo's post prompts me to air my own comment on the SW2 S-meter. I'm not an expert user. There are two radio/software combinations available to me whose S-meter by reputation provides a well-defined,

If the noise blanker is enabled in SW2, or if the bandwidths in SW2 and on the DUO are not exactly the same, you will see differences. Also the time constant on the DUO is long, but short

Here's what Rob Sherwood said: S meter linearity and dBm meter linearity is as close to perfect as one could ask for. Each S unit from S1 to S9 is 6 dB. The dBm scale is within 1 dB from -120 dBm to

In my experience, I’d say the duo is the most accurate. I’d do away with the S meter on sw2. Its obviously just decoration. I think real S meters are for superhets or Japanese hybrid sdrs -

Good evening, everyone, I noticed that the S-meters on the Duo and the SW2 indicate absolutely different values. For example, the same signal on the DUO is at S9, the software SW-2 indicates 9+20

Hello, Gerard, Tony, and Neil, Thank you all for your replies. I have checked on the suggestions that you have made. Everything seems as it should be based on your comments, The issue did not go

Could this be something to do with ADC DC offset correction? Just guessing. Setting is on the Advanced tab of setup Neil

Buongiorno Volevo dirti, prima di tutte le mie esigenze di hobby elettronico e radiofonico, un grande saluto e molto coraggio a tutto il team ELAD Italia e anche a quello degli Stati Uniti che ne

Now that you pointed out that the signal is negative, could it be caused by a notch filter being on ? Just a thought. Tony, EI8JK On 18/03/2020 11:58,

Hi Patrick, Some SDR radios have built-in front end bandpass filters on the receivers and some do not. The S2 and Duos radios have no front-end filters. The main purchase of the pre-selector is

Hello George, I have been running a FDM 1 and now a FDM 2 for years and I never saw this blue line you are refering to. As I am really not specialised in radio , I cant answer to your question The

Who really notices a big positive change with the preselectors available at Elad? Which ones and why? 73, Patrick KM5L

Thanks for the info regarding the 198 microphone. I finally got a tracking number for a replacement microphone today. Took over two weeks, but it's coming.
