Re: Elad S3 versus Perseus and FDM Duo

Yep

Ft8 is very popular for good reasons if not an old school ham. ( I have tried it, worked VK from G land on 160 within an hour!! very very boring, but very efficient..never worked vk on phone as of yet, maybe never will?)

Its more the very inappropriate band planning with it..and the fact that some NOT ALL run mega power on it..

Re ban planning..ie 160m..1840 khz USB..when in Europe some countries have only 1840-1850 LSB on phone. So half that gone straight away..etc.

Anyway sorry enough..keep on ft8’ing everyone..

Regards Other Simon ( not sdrc Simon.)

Well Simon, I prefer not to enter that debate. To be honest I much preferred my radio pre FT8 (especially 6m) but I also do not see the point of pushing a big stone uphill.

On FT8 you don’t work people, just their computers. That’s not amateur radio.

Actually Simon, if you listen tonight on 144.174 (if you can stand it) I have worked 3 stations in IO70 in the last few days as well as EI. I will be on, no need to reply but it will be interesting to know if you hear me. Conditions are not good enough for SSB.

 

I will put 4m up in the next few weeks.

Hi,

 

When we get some decent Tropo we should be able to work on 4m / 2m. Sadly all still quiet over here.

OK Simon.

 

I’m convinced.

 

My only comment would be that I do not use MDS as a metric as I always use an external preamp to set the system noise figure. Even on 6m where I sometimes do EME. While the NF requirements are quite low on 6m using an LNA allows the use of splitters for my transceiver and SDRs and also finding a sweet spot for any situation. It is easy to make a very high IIP3 LNA for VHF these days, just add enough gain to overcome cable/splitter losses and the receiver noise figure. During big Es openings I typically add 6-12dB attenuation, but this covers all eventualities. A step attenuator in the RX path is an essential accessory, does not matter if it is internal or external to the radio.

 

I must admit that I trust Elad and the photos of the innards of the FDM-S3 look very well implemented.

 

So I will buy one. 😊

 

I just remembered that I have a spare transverter for 2m so the downconverter may not be necessary, I will wait and see what Elad offer.

My 10 pence:

 

  1. I assume that you cannot overlap the VHF and HF ranges, you select one or the other?
    Correct
  2. I see several VHF ranges in the manual, one of which is 108-147MHz under sampled at 98.304MHz, so for 2m I just need a good external band pass filter before the VHF input, correct? Of course I will need sufficient gain to make up for the relatively high noise figure, this is easy.
    I think so but there’s a big downconverter coming – suffering from unobtainable parts atm.
  3. On HF how does it compare to the Perseus, especially with respect to dynamic range. I have always found the Perseus to be almost good enough, another 3dB would be enough
    It’s excellent. Can’t give you any figures, but FWIW I think the Airspy Discovery has better MDS than Perseus. Perseus is good but we do have better now.
  4. How does the FDM-S3 compare to the FDM-DUO, I owned one and it was not as good as I expected based upon user feedback. However it would make a fine uwave transverter driver. I probably should have kept it.
    NO comment really – I use the DUO on HF and to drive 4m / 2m / 70cms Q5 Signal transverters, BDR at least 110 dB. For microwave there’s always the Pluto with preamp etc.
  5. If I like it I may buy a second one,  to cover 50MHz and MUF duties simultaneously, it all boils down to dynamic range

I am seriously thinking of buying an Elad FSM S3. At first I was going to buy an ANAN-7000DLE but then I thought about it. The ANAN delays are variable and I don’t really need a transceiver. What I need are receivers.  I see the Elad being useful for tracking the MUF during the Es season and also creating multiple receivers connected to different instances of WSJT-X on 6m

 

A few questions to those who have them.

 

  1. I assume that you cannot overlap the VHF and HF ranges, you select one or the other?
  2. I see several VHF ranges in the manual, one of which is 108-147MHz undersampled at 98.304MHz, so for 2m I just need a good external band pass filter before the VHF input, correct? Of course I will need sufficient gain to make up for the relatively high noise figure, this is easy.

  5. If I like it I may buy a second one,  to cover 50MHz and MUF duties simultaneously, it all boils down to dynamic range

 

I assume that on 6m I can easily create what Flex call ‘slices’. For instance I use a 1536kHz sample rate and I can create multiple receivers, 2 attached to WSJT-X for FT8 and one for 50.110 for example.

Frequency Database - Display Only Entries For Current Time ??

John Dusek
 

Hi -

Still a newbie - and the question shows it.

How do I force/filter the Frequency Database (when Tracking is turned on) to only display entries for the current time? 

I have it loaded and Tracking turned on, but the Frequency Database shows for the current tuned frequency is all broadcasters for that frequency across all hours of the day, but I would like to only display entries/broadcasters who may be broadcasting in the current hour.

Is there a way to do this?

Many thanks - John W3JED

What I need are receivers.  I see the Elad being useful for tracking the MUF during the Es season and also creating multiple receivers connected to different instances of WSJT-X on 6m

 

A few questions to those who have them.

 

  1. I assume that you cannot overlap the VHF and HF ranges, you select one or the other?
  2. I see several VHF ranges in the manual, one of which is 108-147MHz undersampled at 98.304MHz, so for 2m I just need a good external band pass filter before the VHF input, correct? Of course I will need sufficient gain to make up for the relatively high noise figure, this is easy.
  3. On HF how does it compare to the Perseus, especially with respect to dynamic range. I have always found the Perseus to be almost good enough, another 3dB would be enough
  4. How does the FDM-S3 compare to the FDM-DUO, I owned one and it was not as good as I expected based upon user feedback. However it would make a fine uwave transverter driver. I probably should have kept it.
  5. If I like it I may buy a second one,  to cover 50MHz and MUF duties simultaneously, it all boils down to dynamic range

 

I assume that on 6m I can easily create what Flex call ‘slices’. For instance I use a 1536kHz sample rate and I can create multiple receivers, 2 attached to WSJT-X for FT8 and one for 50.110 for example.

Re: Elad S3 versus Perseus and FDM Duo

Conrad, PA5Y
 

OK Simon.

 

I’m convinced.

 

My only comment would be that I do not use MDS as a metric as I always use an external preamp to set the system noise figure. Even on 6m where I sometimes do EME. While the NF requirements are quite low on 6m using an LNA allows the use of splitters for my transceiver and SDRs and also finding a sweet spot for any situation. It is easy to make a very high IIP3 LNA for VHF these days, just add enough gain to overcome cable/splitter losses and the receiver noise figure. During big Es openings I typically add 6-12dB attenuation, but this covers all eventualities. A step attenuator in the RX path is an essential accessory, does not matter if it is internal or external to the radio.

 

I must admit that I trust Elad and the photos of the innards of the FDM-S3 look very well implemented.

 

So I will buy one. 😊

 

I just remembered that I have a spare transverter for 2m so the downconverter may not be necessary, I will wait and see what Elad offer.

My 10 pence:

 

  1. I assume that you cannot overlap the VHF and HF ranges, you select one or the other?
    Correct
  2. I see several VHF ranges in the manual, one of which is 108-147MHz under sampled at 98.304MHz, so for 2m I just need a good external band pass filter before the VHF input, correct? Of course I will need sufficient gain to make up for the relatively high noise figure, this is easy.
    I think so but there’s a big downconverter coming – suffering from unobtainable parts atm.
  3. On HF how does it compare to the Perseus, especially with respect to dynamic range. I have always found the Perseus to be almost good enough, another 3dB would be enough
    It’s excellent. Can’t give you any figures, but FWIW I think the Airspy Discovery has better MDS than Perseus. Perseus is good but we do have better now.
  4. How does the FDM-S3 compare to the FDM-DUO, I owned one and it was not as good as I expected based upon user feedback. However it would make a fine uwave transverter driver. I probably should have kept it.
    NO comment really – I use the DUO on HF and to drive 4m / 2m / 70cms Q5 Signal transverters, BDR at least 110 dB. For microwave there’s always the Pluto with preamp etc.
  5. If I like it I may buy a second one,  to cover 50MHz and MUF duties simultaneously, it all boils down to dynamic range

Hi Simon,

I have an X310 with GPSD0 installed if you would like to loan it. Or an N200 if you prefer - just say the word and it'll be in the post tomorrow. X310 has multi-rate copper SFPs (1G, 2.5G, and 10G) in each, but if you need optical, I have a number of abandoned SFPs so I might be able to assist there too.

It has UBX160 installed, but I have a number of interface cards if you want something else.

I have other SDRs to keep me amused in the meantime.

Thanks and regards,

Erik.

Assuming fairly up-to-date Windows 10 (or 11) on your PC, you can specify the sound output for individual apps from within Windows:
Joe, that Windows routing is primarily for apps that do not have "in-app" routing like SDRC, so the browser, media player etc etc. The setting there does not affect the internal sound routing setting within SDRC that Everett is talking about.

His issue is most likely (I think) to do with the stored output device in the Favourites he is using to recall the band changes. The only other place within SDRC where the audio output setting is stored is in individual receivers when running multiple software receivers i.e. within one instance of SDRC. For example, Memories do not store the audio output device, only Favourites. They store much else as well. That's whey they are so powerful:

Until Everett describes exactly how he is changing band then we don't know exactly what his issue is but AFAIK the audio routing within Windows is nothing to do with his particular issue.

SDR Console v3.1 build 2320

I am not using the beta, that is probably the problem.

I'll install the beta and try it then.

What Version of 3.xx are you running?
Click on "View" in the ribbon bar and under "Spectrum" you should see "Band Plan".
I believe this was added over a year ago? Current version (Public Beta Version) is
3.1 dated March 18th, 2022, Build 2547:

https://www.sdr-radio.com/download
Scroll down just beyond Simon's World Map download (another awesome piece of software BTW) and the Beta
