For now you just want to try and get something to output to your radio, even if it is a bit garbled at first (so consider transmitting into a dummy load where you will disturb no one).

Set the output level on your radio's soundcard interface to 75-100% for starters, as you can dial this back, if needed, later on should you notice excessive ALC activation on transmit (there should be little to no ALC activation when using digital modes). Look over your available menu options carefully to see if you can find the equivalent setup options as I suspect they probably exist on your radio.Īlso check the Audio levels being output to the virtual USB soundcard (I'm assuming the audio is via the USB cable?) using your operating system's Audio Mixer app (in Windows, this would be the speaker icon in the system tray, right-click on it and select " Playback", or similarly titled, levels).
JT65 HB9HQX PLUS
On my radio there are separate level and parameter settings for both Mic/voice and Data port inputs plus an additional setting that controls whether VOX is monitoring the Data line or the Mic input - and they are not all grouped together in the same place as one might expect. You will activate and deactivate VOX from your radio's front panel VOX control.Ĭlick to expand.If VOX on your FAt-991 is anything at all like my FT-950 (I have not downloaded and read your manual) then the VOX settings, including the choice of input source, can be found buried in the setup menu settings. If using VOX mode, be aware that some Yaesu radios have separate VOX configuration settings for the DATA and the MIC ports, and that you may need to tell the radio which of those two ports (Data or Mic) it should be monitoring so that VOX is looking at the correct input source - if turning VOX on causes the radio to transmit on your voice, rather Than your data signal, then you'll know that the radio is monitoring the wrong VOX input. If your application does not support a compatible means of activating the PTT line directly, for your radio, then you will have to setup your radio to use VOX mode instead so that the radio itself responds automatically to audio input without the need to trigger the PTT line.
JT65 HB9HQX HOW TO
You do not state which JT-65 application you are using (there are several common candidates) nor precisely how you have interfaced everything to the PC (other than mention if a USB cable), but if you wish to use automatic activation of the PTT line then you will first have to tell the application, from its configuration panel, how to activate your radio's PTT line as there are a number if different ways this can be done for various radios (such as via CAT, via switching either RTS or DTR on a virtual serial port, etc.). I would wager that this is a bug in JT65-HF and I'd probably have better luck with HRD, but frankly, I'm not in the market for a payware PC program.I don't have a 991, so this is somewhat generic information. I have tried setting the radio to key USB data with RTS and DTR and disabled CW and RTTY from the USB virtual COM port. And I noticed that if the PTT has been in 6 seconds and I halt JT65 transmission, it will work correctly as long as it hasn't been unkeyed for more than about 10 seconds. They key it instantly and flawlessly, whether I'm sending AFSK through the 7300's internal soundcard or triggering CW using DTR or RTS to hard key through the virtual COM port. It doesn't do this with Hamscope or Digipan. I can override this by manually pressing the PTT key on the mic at the start of the transmission, but I have to hold it for 6 seconds before releasing or the PTT will just drop back out. It has a 6 second delay between the time JT65-HF starts sending and the time the PTT actually engages in the radio. I just started using my new Icom 7300 for data (JT65, PSK31) with the USB cable connection.
