Bob, sure, so long as the PA has sufficient harmonic suppression for Amateur Radio use. All the WSJT-X modes use constant envelope output and linear amplification is not required for that. Note that

The answer would be NO. FT8 and FT4 is a tone modulate SSB type signal. You cannot put an SSB or modulated signal through class C amplifier without distorting the signal. The maximum class you can

I've not seen any clear or definitive answer to the question "can one successfully run FT-8/4 or other WSJT-X modes via a Class C solid-state VHF amplifier?"  Asking because I have a VHF amplifier

You do not mention what you gave for cat control , a signalink is not a cat device

I suggest BktTimeSync

Hi Gentlemen, If you make a shell command file with the necessary command line entries and include it with startup items, then every time you reboot it will automatically set the parameters for WSJT-X

Thank You - Success at last! Adjusting the VOX delay down to minimum fixed the problem. it was up at some ungodly number. I will try PTT later. VRY 73 Dan Sent from my Verizon, Samsung Galaxy

No joy. Same problem with 2.5 RC3 Sent from my Verizon, Samsung Galaxy smartphone

Humm. I see only 2.5 RC3 and I'm willing to try it but still, l had no such problem a month ago on my old installation Sent from my Verizon, Samsung Galaxy smartphone

Dang! It's 2.4. I'm embarrassed that I didn't check. I will update and report back. Thanks! Sent from my Verizon, Samsung Galaxy smartphone

OM, which version of WSJT-X are you using? If it is not WSJT-X v2.5.0 RC3 then can you try that please? Your rig may require that "Settings->General->Allow Tx frequency changes while transmitting"

Hi Harry, it is Windows shells like CMD that are picky about path directory separators, the underlying file system accepts both, nothing to do with the Windows kernel. They are

Dave, I just got home from a trip. I am pointed your way, calling CQ on 2nd 50.275-30A on 1500 Hz. You or anyone is welcome to call. I'm running about 600w out to a 5 EL LFA @ 55'. It is 21:30z right

Fresh WSJT-X installation on fresh Windows7 SP1 machine. WSJT-X works and I'm able to make FT8 contacts (WSJT-X even controls the split transmit freq), but I get a Rig Control error message after each
