Re: [wsjt-devel] Rare negative DT

CN8KD is "famous" on 6m ES for a negative DT on FT8, sometimes over -1.5, making contact with him very difficult. 73 de CT1GVN On Wednesday, August 9, 2017, 11:53:34 PM GMT+1, Alessandro Gorobey via wsjt-devel wrote: Hi, working in FT8 have seen that in column DT the negative values are rar

[wsjt-devel] 1.8.0-rc1 User manual: FT8 protocol description

Hi all, Looking at Section 16.2.1 of the rc1 User Manual, it says in the first sentence that there are 75 information bits and 174 channel symbols. (Later in the paragraph it says there are 79 channel symbols.) AIUI, this should be 75 payload bits, 174 information-carrying bits and 79 channel sym

[wsjt-devel] Why wipe Tx6 message?

The first FT8 DXpedition using FT8 will occur this weekend as OH2BR & OH2JR operate from Market Reef as OJ0BR & OJ0JR. In responding to an email from Martti, OH2BR, I suggested that since he would not be able to copy anything from multiple stations calling on the same frequency, that he run sp

[wsjt-devel] Suggestion for FT8

When a really high signal comes in, the auto-reply feature in FT8 really goes crazy! It would be nice if it would auto-reply to the frequency with the highest dB value.. I've never seen a signal that high! Luckily, I was able to get the QSO to complete. 73 Dave W9BOO

Re: [wsjt-devel] Why wipe Tx6 message?

Bill, Yes, I know that the Tx5 messages can easily be stored and retrieved. But in R8021 and other builds, when I click on a call of a station replying to my CQ, the special message stored in TX5 gets wiped out. That means every time I want to again use that special message I need to go the
