I really like TeamViewer. I control all functions and monitor my S2 and S3 receivers (located in my unheated shack (garage)) from the comfort of my home office. TeamViewer is free but is very strict

Hi Klaus, I was wrong on the QST Review. I got my numbers mixed up. Looks like the value was 99 db at 14 MHz for a 2 Khz spacing. 73 Clint W7KEC

<quote W7KEC> It is my understand that the QST Product reviews use a 3rd signal to simulate noise. They measured a DR of about 70 for the Duo in their 2016 review. <unquote>

Team viewer?? I'm not familiar with that.

Some like the NPR tests and some do not. The NPR test equipment is very hard to find – most of it is 30 to 40 years old. However, a complete set of equipment can be purchased for about $300. On

For Rob’s receiver tests, he turns on Dither is the radio supports that option. The IC-7300, the Perseus, and other models support dither. However, there are radios that have a very high DR

Mark, Glad the interface got you going OK. The Hardrock 50 is a great amp. I just got a Hardrock 500 kit completed a few weeks ago. It works great on the FDM-DUO, a very neat portable station. I

I had the belief (from tech articles) that NPR measurements are the way to go for -at least - SDRs. Analog and SDR transceivers and receivers behave different

If the two source signals are pure tones, then you'll get pretty terrible results as there is no dither signal injected into a DUO as far as I know. A proper test of a radio with a

Single / two tones tests on a wideband SDR are meaningless as they tell you nothing about the quality of the A/D process. The proper way to test such a receiver is with broadband notched noise, or a

Anydesk is also a good alternative. On 12/01/2021 17:46, Alberto I2PHD wrote:

I am not sure. I don’t have the ability to inject a signal from a 3rd signal generator. A couple of things to keep in mind. Putting a HF pre-selector on the front end of the Duo should improve

Hi Clint, does injecting a realistic level of wideband noise (or some additional non-harmonically-related signals to provide dithering) change the results at all? Neil G4DBN On

Reading some interest regarding the various tests by experienced ( ! ) facilities on FDM recivers........ I have purchased probably over 20+ various makers of receiver models for the last 50

I just ran the same tests several times on my Duo. The results came out the same each time. The challenge in testing the Dynamic Range of SDR receivers is that the DR bounces all over the board,

What's right, what's wrong? QST tested the ELAD FDM-DUO in issue May 2016 @ an IMD DR at 2KHz with 99 dB (shortwave bands) with a remark. Sherwood tested the

For those that might be interested, Rob has posted updated test data for the Elad Duo on his receiver test site. http://www.sherweng.com/table.html Rob shows the dynamic range for the Duo to
