Re: Laptop suggestion FDM-S2

Jan Barendrecht
 

I could run all SDR radios on my old Asus A7J (~2006) laptop, the G31DDC even with demodulator filter length set to maximum (5,000).
It's fitted with a dual processor, CPU clock didn't exceed 1.8 GHz and memory clock was just 400 MHz. Even the most modest laptop
today has better specs. I used it with external monitor, keyboard and mouse and while one of the radios was playing I also was running
circuit simulations with Microcap and / or browsing / downloading pdf. If you use the laptop only for radio, about anything goes. With
internet connectivity disabled, you can even run a slimmed-down version of Windows XP or 7, without security issues. Try to get a laptop
with SSD and as many USB ports as possible.

Re: Laptop suggestion FDM-S2

Bill Nollman
 

My suggestion is to do what I did for a friend. Buy the FDM-S2. Buy a laptop at your favorite local box store that allows returns with no questions asked. Test it for a few days. The problems that I’ve seen most people run into include:

- laptop or PSU generated noise (Lenovo T410 is useless for example)

- poor hard drive specs causing 6MHz recordings to skip (internal SSD might be fine but is it enough space for recordings? At 6MHz you need 120GB/hour).

- lousy battery life (if remote DX is important to you).

- not enough USB3 ports for the SDR and any peripherals.

 

You might also like touchscreen. The S2 does work nicely with that!

What we’ll need for FMD-S3 and 24MHz recordings is TBD.

 

I already told you my recommendation for the perfect laptop W540 with options. Search the forum and you should find this discussed plenty of times. If all you want to do is listen (no record) at 1.5MHz bandwidth you can probably get away with just about any decent laptop $400 and up.

Time flies, as they say, and with time everything, sooner or later, becomes obsolete... so it is not
unreasonable to expect that, sooner or later, there will be a successor to the DUO... but I would
not hold my breath for the whole 2017, and for part of 2018... the DUO works so well that it would
really be a pity to put a premature end to its life....   :-)

Re: Tmate2catcontrol software

Richard Brown
 

The Tmate2 has been renamed TM2 Desktop SDR Controller, now carrying the Elad brand, but not sold on Elad website, yet. Perhaps it will be on the website with the necessary support files for Perseus when Elad announces its new receiver, the S3. Or not. Or not free. But you can buy the TM2 Controller now on the WiMo dot com website, which only has the Owner's Manual, no other support files.

Sincerely, 
Rich Brown

I forgot to add that there is an FDM-S3 in the wings, with a wider
capture range. Not sure about the transmitter models though. I haven't
heard any rumours about anything beyond the DUO (yet :-) )

Hi Mike

I'm a DXer & SWL and have, or have had, the Elad FDM-S1, -S2 and DUOr.

The DUOr is the most versatile receiver I've ever owned. I've never had
a problem with any Elad product, but I don't transmit, so cannot
comment on that. Support from Elad is great - very personal and
knowledgeable.

Not sure there will be too many used sets out there :-)

My Duo seems to run hot - around 40 degrees Celsius after an hour or so of RX only. I've seen a few comments about this but just want to check this is normal?

I just use the N1MM+ or Tucnak or other contesting program voice record/playback facility and point it at the FDM-DUO audio input stream, along with serial port PTT, works perfectly.

Hi guys,


Is there a way in the FDM-SW2 software to record 3 or 4 short VOICE messages for

I want to save my vocal cords while sending “CQ” during Field Day !


Can these be sent by the MEM1 thru MEM4  buttons in the DUO-MANAGER ?


Or is there another way.

True, in so called "zero IF" SDRs there's the trouble with
DC offset. That prevents carrier-derived AGC so such
SDRs are using audio-derived AGC which sounds like an

"Zero IF" SDRs are not the state of the art in the SDR field... they are usually based on the
so-called Tayloe detector, more correctly known also as a QSD (Quadrature Sampling Detector).

The best SDRs use the RF direct sampling, where the RF signal is digitized directly after the
antenna, then downsampled and downconverted digitally. This architecture does NOT have the
problem of the DC offset...

Because many producers no longer provide circuit diagrams, the only way to evaluate

receivers is observed and measured performance and comparing the results.

Those with a calibrated signal generator can measure input signal at the onset

of clipping, the signal required for a certain S/N, and what happens when the

amplitude modulation is switched from for instance from 80% to 0. A more

sophisticated test regards synchronous demodulation in the presence of selective

fading. Been there & done that, I still consider the G31DDC plus successors among

the best SDRs and will read tests with comparison of the SW3 with great interest.

Those unfamiliar with the issue of audio pumping can run the SW2 with the HDSDR

program and tune to a strong (S9 + 20 dB or more) MW talk radio station with AGC "on".
