Hello Neil, I had a quick look at a couple of reference books, and I'd expect that the background noise from all sources in a quiet rural location at 30MHz to be about 20dB above the threshold of a

Hi It does not normally need any preamp. ( maybe for moonbounce on 6m.) I have never needed one here..( not moonbounce) But you may need to switch in attenuator below 10mhz to stop

My understanding is that you don't need much sensitivity at below 20m as natural band noise (QRN) is high and any "extra" sensitivity makes no difference. But at 29 and 50 MHz, QRN band noise is much

I only use FM on 10GHz rainscatter but I haven't noticed that nbfm demod is radically different from other modes. Sensitivity on 28 and 50 on other modes is identical to other bands, it only drops off

All downloadable. Use the current versions on the website. Only use for the stick is for upgrades to the firmware as there is a limitation of volume size withe the hardware boot service that needs

Download area - ELAD (eladit.com) No activation code on the stick, you can find everything in the download area of Elad. greetings Uwe

The FDM-DUO is supplied with a USB memory stick which contains the SDR software and user manual. Can this all be downloaded from the Elad website for free? Or does the memory stick contain an

<quote> Or is it a future option or Firmware update? <unquote> IMHO, given the current HW design of the DUO, there is no likelihood of having an additional

There is no additional/switchable RX pre-Amp in the DUO. If you need more Sensitivity for receiving FM on 29 and 50 MHz, you'd need to add an external pre-Amp for

Does the FDM DUO have a switchable RX pre-amp? The User Manual (page 13 Rev 2.6) shows an LCD display with all the display option shown. In the top left hand corner there are 3 options shown: LP ATT

I have checked out the QST review for the FDM-DUO and the FM sensitivity for 12dB SINAD on 29 and 50 MHz is 1.26uV (-105dBm) and 1.62uV (-103dBm). This suggests that the FDM-DUO is around 15-17dB

For me the Downconverter was the reason for buying the FDM-S3, Elad shouldn't just leave its customers like that. Inquiries by mail are not answered at all, I think the Perseus22 hype pushes

Just stirring the pot again to see if there is any new information re Downconverter future availability timeline. Has a source been found for the TCA9535RTWR chips?

Nice... I can't wait to get home from the hospital to work with mine. It came the day I left...

Elad Italy-based repair is slow, unfortunately. Supply chain, lack of labor and covid precautions. I still love my FDM-DUO. I have two, just in case. :) -- Paul Andrews SVP - Business

Chet, I don’t have a specific response on ELAD repairs. However like you, I have tried to contacted ELAD USA (several times) as I’m trying to buy a Duo ART 120. If anyone has a 120 for sale

Hi Guys! Sent my Elad FDM-DUO in for repair. Mailed my unit to the Ridgeville, SC transfer point to Italy on 3/18/2022. It took awhile to get to Italy, but it was eventually repaired and shipped on

Nice to hear from you George! It has been a while. We are still in Grants Pass. We had 2 sets of friends who moved to Bend/Redmond. Since then one couple moved somewhere in Idaho and the other moved

Hi Dave, A good choice. The only thing that has gone wrong with my S2 is the blue light no longer works. Take care, George, NJ3H Redmond, Oregon

I have decided to NOT sell my pair of ELAD S2 radios! They work well and are keepers. Doesn't seem like anyone was overly interested anyway, so I don't think I caused much disappointment. HaHa! Dave
