David, The DXpedition User's Guide, section 11 has the answer to your question. It says:
"You will need to re-activate Enable Tx (or hit Enter on the keyboard) at least once every two minutes. (This restriction is to ensure that an operator is present and paying attention.)". 73, Rich - K1HTV = = = K2DBK wrote: From: K2DBK-WSJT <[email protected]> To: "'WSJT software development'" <[email protected]> Cc: Bcc: Date: Mon, 7 Oct 2019 21:28:24 -0400 Subject: [wsjt-devel] F/H stops calling after 5 cycles I’ve noticed that in F/H mode after I call 5 times Enable Tx will turn off, similar to what happens in non F/H mode when the Tx watchdog expires. However, unlike in that case, there’s no red indicator in the lower left corner, it just stops sending. I’ve confirmed that my watchdog timer is set higher than that (just in case) and it’s set to 6 minutes. The number of cycles seems to be consistent, and I’ve got no issue in other modes, ruling out something like RF causing an issue. I’ve looked through the documentation and couldn’t find any reference to maximum number of calls before it will stop on its own. I’m not transmitting on top of the Fox, I’ve seen this both with and without “Rx All Freqs” set. One thing I’ve noticed is that just before Enable Tx turns off, the Decode button will flicker very briefly, something I don’t see at any other time. Also, even though it seems to be on the 5th transmit cycle, it looks like sometimes the Enable Tx button will turn off just as a transmission is starting, and sometimes immediately after it’s finished. I’m baffled. I’m running v2.1.0 on Windows 10 1903 build 18362. I’ve got Save All checked in case those files would be of any use in diagnosing this. 73, David, K2DBK
