[bars] A quick question going digital

[Paul Pellegrini]

Jason –

Ken has given you some good ideas for places to check.  Here are couple of other things you may wantto investigate.
·      Where is the PTT being generated?·      Does this correlate with the PTT in the rig tabin settings?·      How is the audio getting back and forth from yourrig to the computer?·      Did you check the audio sources in the audio tabin settings?·      Are they the same as you believe they are?

 Ken, thanks for the reply! 

Well, I cut a bread tie and stripped a bit off the ends, a pair of alligator clips attached to some ear buds, other ends holding the two mini probes, with a couple pliers to hold the cable down, a bright light and some magnifiers I probed gnd and data in to find the audio tone (quite loud) while wsjtx was running the 'test' tone.  

I've tried digi as well as usb, I can decode the ft8 data and the applicaton is good at reading and setting the rig controls.

The rigblaster plug-and-play module has a 3.5mm 4 contact TRRS connector and a break out cable to audio in/out, I have one laptop with in/out ports and the rest use the TRRS for headset/mic combos similar to a cell phone. Rigblasters support could not tell me if a double ended TRRS cable would allow me to attach to the newer laptops.

Hi Jason,

 

Need a bit more info:

 
   
   - How do you know audio is getting “to the end of the data cable”
   - What mode are you trying to run?
   - Correct sized plug/jack combo? 2.5mm?
   - What is the audio source? Sound card?
   -

So attempting to get a Yaesu FT817 up and running on digital modes for experimenting.

 

My issue is that I'm getting audio to the end of the data cable and the ptt is being activated but the meter is showing pretty much nothing for audio output, almost as if the jack is broken, I checked for any bad solder joints on the board and everything looks decent and not showing any open or high resistance.   I'm a little new and confused I'll admit, my system is running linux (knoppix) and everything else is working, decodes, rig control etc.  I'd almost wonder if anyone had any suggestions! 

 

Working on my drone practice with the plan to fly a nice high messenger over the treetops to facilitate pulling a wire up for an end fed

 

Much Obliged
