Hi Group. 



Would like to scan frequencies that Multipsk provides using my Elad FDM-SW2 SDR with Commander from DXLauncher197. Receiving only. Using Yaesu FT897 CAT to control the SW2 on Com port pairs 3 and 4. 

Multipsk shows Connected into Commander. Under QRGs in Multipsk clicking on a frequency the Commander VFO correctly changes to the frequency that is in database. 



So my problem is how do I sent the CAT command to the SW2 to change frequencies from Multipsk via Commander? 



Thank you for your interest.

HC-05 Bluetooth chip stuck in Programming mode.... (Blue DUO)

Chet Roberts
 

I wanted to program a couple more HC-05 Bluetooth chips for some fellow hams, but unlike my earlier purchases, these chips start in Programming mode (slow flashing red LED) and I cannot figure out how to get them into OPERATE mode.  These are the chips that have the tiny microswitch on the board.
I'm using a Raspberry Pi running Cutecom to do the programming.
Thoughts?

Error code coming up on FDM-DuoR

jonathan wood
 

Hello,I  have just got a new FDM Duo-R and have been running it successfully for 5 to 10 mins, listening to a local station,  when it cut out and the following appeared on the screen: "WRONGF PGA" (I wonder if it means wrong FPGA, but the message is as I've presented it.) The receiver is connected to a DiaMec sealed rechargable battery, which is reading 12.3v. There is no audio at all. Any suggestions gratefully received! Jonathan.

Re: Most current, stable, SW2 release???

Neil Smith G4DBN
 

1.144 seems to be the most reliable recent release, is there a general consensus that this is the one to use for production use? I am on 147 and there are some rough edges with lockups using SET in particular, but I'm happy to work around them in order to help the product develop. I had a weird event last night when setting a CW split TX by clicking on the yellow TX, the rig jumped from 14MHz to 28MHz and I lost the 14MHz red channel completely. I can't reproduce the fault, so I'll blame it on Microsoft for now.

The lockup and screen flashing when I do a save within SET is annoying, particularly during a contest, but I'm not going back to 1.144 just because of that.

+1 agreed, I'd rather have a stable version that doesn't keep crashing.

Recording rate .

Mark Pettifor
 

At any given bandwidth, say, 1536(1229), are there any settings to change the "resolution" of the data stream being written to the hard drive? Right now I'm getting about 30GB / hr disk usage. Is there a way of reducing that, other than reducing the receive bandwidth?

Volume still there in ver 1.147 and it adjusts volume for the internal speaker in the radio

Hi Alberto,


I am not mixing E1 with E2. I am aware of how to adjust aux volume using E2. However in the past I was able to (upon start up) click E1 three times and an Aux volume control came up and could be adjusted by turning the dial. That function went away and I wonder how to get it back.

Audio recording volume low

Neil Smith G4DBN
 

I am recording CW in 100Hz bandwidth, using the audio recording option, but the volume when I open the WAV in Audacity is at about -25dBm. Is there an adjustment for this within SW2 or is it something I need to change in the Windows sound devices?

FDM-DUO config for Winlink/Winmore?

engineer1@...
 

Has anyone tried to configure the FDM-DUO for Winlink/Winmor operations.  I'm trying to use a Windows 10 system where FDM-SW2 seems to be working properly.  I am having zero luck at getting anything to work.  I am pretty new to the radio and still learning.
Thanks for any help - Will - N7IPY

Something similar was discussed abt a year ago.. 
I copied one msg below, hopefully it is of some help..

the waterfall says it has a FFT bin with of 11,7 Hz, and the S-meter is using the noise power of a 192 kHz bandwith!

11 Hz equals ~10,4dB WRT 1 Hz and 192 kHz ~53 dB, so your S-meter should read 43 dB more than what the waterfall shows.

Now your S-meter says -71 dB and subtract 43 from that and you get -114 dBm

Try reduce the demodulator BW and the S-meter should start to read lower due to less noise power.

You have a better specs on computer/ audio-card, than what is inside the Duo.

Can anyone explain why I see signal levels on my FDM-DUO that are 20db lower than what I observe on the SW-2 software?  It seems that my radio may show a noise level of let's say -80db yet the spectrum trace noise level shown in the SW-2 software is more like -100db.  Do I have something set up wrong in the software?

Equalizer question + issue RX1 > RX2

Patrick <aunumero73@...>
 

Hi Group,

Probably a silly question ....
I just downloaded v1.144 and did not succeed in making the equalizer work ... The sliders turn to green when moving them up, but there's no effect at all on the audio.

Besides this, if I close the RX 1 AF window and I select RX2, an 'error' message pops up.
No issue if I stick to RX 1

The error message (see below) says that it's impossible to access a deleted item. (item = label)

Pat.

You are mixing E1 with E2.... press the "Menu" blue button, then rotate E2 to reach menu Nr. 6, "Aux Vol".
Now press E2 to signify that this is your choice. You can now rotate E2 to set the Aux Vol to the level
you choose. When done, press again the blue "Menu" button to terminate the function.

Hi Chris,

Previously I could scroll through the menu items by repeatedly pressing E1 until I found aux volume. I could then set the level by rotating the knob. This menu item has disappeared and I don't know how to get it back.

Hi,

you will have to activate the menu via button and scroll through the items.
Then you can choose the "Aux volume" and change it with the rotary switch (E1, but I'm not sure).
A permanently setting for changing the Aux volume value with E1 is not known by me. Refer to elad support to make a feature request.
