Winlink configuration with the uBitx


 

After scanning the message archives, and finding a good bit of Winlink references, but nothing helpful for setting up WInlink to work with the uBitx, I thought I'd post a direct question to the group.

How do you best interface and configure WInlink to work with the uBitx?

My current configuration has failed:
uBitx with the CEC firmware V 1.061
soundcard interface directly with the mic and speaker jack (worked well with FLDIGI)
USB connected to raduino

Winlink setup under radio setup:
Select Radio Model: Yaesu? FT 817
USB
PPT Port: COM12, Baud 38400

When I do this, the uBitx just keeps re-setting at each PPT attempt.

I've tried soldering a 100 ohm resistor as Ian Lee suggests on between the V4 and Reset pin, just no luck

Any suggestions from the group?


 

If I remember correctly, the arduino being reset usually is caused by the DTR of serial port. You might need to find a way to configure the serial chip to not use the DTR pin. I have been meaning to look into this as well, cause each time I start up wsjt-x, the ubitx resets.

Geewhiz, I don¡¯t think this is hard at all. ? I don¡¯t quite understand exactly what you¡¯re doing. ?Get some sort of sound card interface, either a signal link or a homebrew,

Connect up the microphone connection to the Microbit X microphone.

Connect up the speaker connection to the MicroBit X speaker output.

Connect up the push to talk connection to the MicroBid ask push to talk.

Put ferrites on the microphone and speaker connection.

Connect the signal link or sound card to your computer. ?Put ferrites on that connection also...

Start with relatively low power, you can set that by setting the transmit gain on the signal link fairly low. That will reduce your chance of having radio frequency interference.


Don¡¯t connect anything at all to the raduino USB interface. ?It is a very vulnerable point for radio frequency interference.

At this point you should be able to do the WINLINK transmit level test without any problem.

Pick any legal frequency and initiate a call to any WINLINK station, don¡¯t try to connect yet, just make sure he can get through a series of calls without crashing. ?You need to be in the CW/digital portion of the band

Finally, try to connect to WINLINK station. Remember they center frequency is 1.5 kHz up from the dial frequency. And they all use upper side band.


Where are you located? If you can connect to Florida, I can try to listen for your signal.

It always takes a bit to get this going but once you figure it out it¡¯s easy.

Cheers
Gordon

I use the usb for cat control and do not have too much trouble. Sure it raises the local receiver noise a small bit, but its not enough to worry about.

Lucky you.
Those 12 and 16 mhz resonators on the Nano are not very accurate, could be spot on
or could be several thousand ppm off.? If close to spot on, you can get audio beat notes
with our 12mhz BFO.? Doesn't happen very often though.

I do get tones in the passband on 20 meters. But its never been enough to wreck havoc on psk or ft8. Just a minor annoyance when I listen to the digi transmissions.

Ahh ok, so I think the issue is the PTT.? My sound card interface is very simple, it's a USB dongle with a speaker and mic jack and no PTT control.? I was hoping to control the PTT vial the USB connection.? Is this a possibility?? Or do I need to build a circuit to basically replicate a VOX circuit?? All the help and commentary is appreciated!
Josh


 

Use the CEC firmware with Omni-Rig. Set Onmi-Rig for FT-817, 38400 baud, 8,N,1.? In WSJT-X, set PTT:CAT, MODE: USB, and Rig: OmniRig.

If you are able to create the PTT using CAT control and the nano usb connector, yes, that will work and you won't need to create the vox-type ptt circuitry. However, in my experience, the usb connection is MORE VULNERABLE to radio frequency intereferennce, which may manifest itself by any of several symptoms, inclluding locking up the nano, locking into transmit mode, and/or distorted signals.

For that reason, you may eventually decide that going the VOX route is less troublesome. If you wish to do the CAT-type PTT I would test its functioon first at very low transmit power (easily enough done y simply turning down the transmitter gain on a signalink or similar device); if it functions well at very low power level [goes into the transmitand back into receive approprriately] then slowly increase power to full power while connected toyour well-tuned antenna of choice, and verify that it remains fully operational.

I would suggest one or more ferrite connectors on the Nano usb connection, and shielded cable if possiible!

Good luck, getting these digital things to work it always a bit of effort, but once you have the hang of it, it is easy. I have used mine to connect to multiple gateways in several states with good conditions. On 80 and 40 the output power of stock devices is quite suffficient.

Thanks Gordon, that was by far what I was looking for, a real "Why" you do it the way you do.? I'll follow your advice and look for a VOX solution and be cautious about stray RF impacting the USB interface.? Great advice!
Thanks!
