Elad FDM-S3 with DL2EBV band filters


Francesco Di Giovanni
 
Edited

Hi,
I own an Elad FDM-S3 equipped 
with DL2EBV band filters.

When I switch between ranges e.g. from 5MHz to  e.g. LW 60kHz, it's like there is an AGC problem.

The signal level is very low and only by going to an intermediate frequency between the two and returning to the LF, the situation returns to normal.

The same in reverse.

This does not happen with Elad SW2

 

Any idea?

I'm surprised - sounds like the commands may be sent too soon. I don't have any filters, will have to buy a set for testing. To be honest I doubt you really need them.

Simon,

I have the filters in both of mine. I had to send my Downconverter back to ELAD, as the USB C broke off of the Downconverter circuit board while installing it. ELAD should Receive it today.

Was the filter switching OK? I have to send my S3 back - I've lost VHF sensitivity and will buy a downconverter when they arrive on the website.

What's the downconverter frequency range?

I don't know on the filter switching, as I have been tied up moving over to the new computer. I will play with them when I get a chance. I would not wait for ELAD to list the downconverters  on their website . I would send a email directly to ELAD requesting the doenconverter.

Simon,
 
This is what they sent me:  54MHz-69Mhz frequency range is not available, this is a limitation we are trying to fix quickly,- the maximum tuning frequency is 4.25GHz, with a decrease of performance from 2GHz - 2.5GHz up to 4.2GHz.
