Digirig mobile and FT-891 issues

I’m using the Digirig mobile with FT-891 running FT8 and having a couple issues. First, when if goes into tx, it only transmits momentarily, and then sometimes it transmits normally. Second, when I close out wsjt-x or winlink, the radio stays in data mode on all bands. Is this normal?

Paul,

Let’s look at your WSJT-X configuration. Can you please share the screenshot of the “radio” tab?

Here are the current wsjt-x settings.

Thank you for the screenshots.

When momentary transmits happen, does the radio reboot or goes back to receive? Does this happen with RF power set to minimum?

It goes back into receive, and seems to be decoding well. I haven’t turned the radio power all the way down, it’s at 30. I’ll give that a shot now. Thank you for getting back to me!

Denis, it’s doing the same thing with power at 5, the lowest setting.

Not likely RFI related then. Per your configuration PTT is handled via the serial commands over CAT control. This includes the start and end of the transmission. The abrupt end to transmission is either to a serial command issued prematurely from the software (unlikely) or radio ending transmission on its own.

Let’s try following:

  1. drop baud rate of CAT to 9600 both in WSJT-X and radio’s menus - this was recommendation from the setup tutorial
  2. confirm all other prescribed transceiver settings
  3. see if radio holds transmit as expected while using PTT test or tune feature in WSJT-X
