Re: DRAWS + FT-891 + WSJT-X/FT8
Yep… good contact and you went “automagically” into my HRD logbook here. Not too shabby. There was a lot of nearby traffic so I was afraid it wouldn’t go through. Enjoy the DRAWS hat… I have two here, one of the initial early experience release units and one I received about a week ago. The older one is in dedicated Xastir service as my digi/gateway (kd4iz-3), so the new one is going to be used for all my portable unit experimentation. My side of contact was made with the IC-7300 @80W and a GAP Titan vertical dipole. Terminal was my Windoze workstation… this time – no DRAWS (sigh).

Here are my signal reports for today. Pretty good overall I'd say:

I was looking at the menus last night and it was getting too late for me to spend much time on it.
That's great info you got form Yaesu, i was thinking of doing the same today. Maybe you get to figure out the right filter settings for the rest of us now too 73 ;)

Re: DRAWS + FT-891 + WSJT-X/FT8
Yes that definitely looks like a narrow filter on the 'data' setting. The calculation (which is also built into DRAWS™ Manager - http://localhost:8080 - https://www.youtube.com/watch?v=v5C3cWVVz_A ) is for the transmitter side of things and has nothing to do with your received audio. In DRAWS™ Manager -- use the Input from Receiver "Analog Gain" control. Actually this is usually very tolerant, and since you get lots of signals on USB, it is probably fine -- again, this looks like a filter problem.

Re: DRAWS + FT-891 + WSJT-X/FT8
Steve,
Looks like you have a very narrow filter width defined in the radio? Can you open that up?

Alright, making progress left and right today.
Turns out my input audio levels are too low. I get to decode some signals, but not all of what is out there. I'm currently getting about 2 or 3 signals per cycle.
I followed the steps in Brian's video (https://www.youtube.com/watch?v=RxWiDYMcRn4) where he uses alsamixer to set levels. LO is at -6.0 and PCM is at -11 and that is where my ALC starts to move.
The signals coming in are not great and my waterfall looks like its been truncated:
I called Yaesu tech support and they actually didn't have a reference for this input (-1 for Yaesu!). But they told me no more than .5 volt and the recommended setting is 100mV
Using Brian's spreadsheet I get
for .5 volts I get -3 for .1 volts I get -17
Neither of them improve the results or the waterfall.
For reference when I have the rig set to "USB" this is what the waterfall looks like and I get lots of signals in:

Dave,

A short answer to your question. In your case with the ICOM products you are %100 correct in that most of the things you want to do are embedded in the radio. However, you are limiting yourself in many other opportunities. The DRAWS hat provides you with two interfaces to work with along with a much more capable CODEC for a stunning variety of other applications and modes. It is an experimentation environment ripe for you to go and expand your horizons. Hope this helps... 73 de Steve, N9VW

Re: DRAWS + FT-891 + WSJT-X/FT8
Steve McGrane <temporarilyoffline@...>
So that is really interesting. On my working setup I made a few contacts on 40m last night. This setup uses the radio in USB mode, not Data/Pkt. When I switch DRAWS to Data/Pkt I am able to transmit and my signals are heard, but I no longer can decode any signals. So I can have one, but not the other. Still stumped, but maybe that is some progress in there? Purple is from 40m on the working setup from last night, Yellow is from today on the DRAWS on 20m. No receive on DRAWS

You can do it either way, but if you're not using the DIN connector, you're not using the DRAWS.

I haven't tried the draws hat or image yet, but i can run my 7200 and fldigi off a straight pi with only the usb.

For the OP, the other thing you could check is that you're in the right mode. I forgot to put my radio in "data" mode at one point and when it transmitted it opened the mic causing feedback. Took me a minute to figure out what was going on. I have SSB set to use the mic, and data set to use the rear connector (in the menus)

After making my own cable to connect an IC-706 to the DRAWS, I think the hammadeparts.com cable is worth the price.

The IC-7300 has only a 13 pin DIN connector. You would need create an adapter with the 13 pin DIN pigtail that came with the rig. If you no longer have (or never had) one, the MFJ-5213 will work for the rig end. See the pinouts on page 12-1 of the IC-7300 manual.

It sounds like you're running the 7300 from its internal sound card (audio codec) via the USB port, rather than from the DRAWS hat. You must connect the DRAWS hat to the 6 pin mini-din on the rear of the 7300. Then select the DRAWS hat as the audio source in fldigi, after its configuration. Apologies if I misunderstood your configuration. 73 Julian oh8stn Julian OH8STN

Re: fusion on bluedv

That would be a question for info@... -- also David frequents the AMBE subgroup https://nw-digital-radio.groups.io/g/ambe The ThumbDV provides AMBE encoding/decoding but the various protocols (D-STAR, Fusion, DMR, ...) are handled by applications like BlueDV.

Hello,
Was wondering if fusion is working on DV3000 with bluedv yet? I searched for posts however, nothing posted lately. Tnx Mike W8VPC
