Re: LF: 500 kHz WSJT JT4A

[Gary - G4WGT <g4wgt@tiscali.co.uk>]

OK Andy,

Any suggestion is welcome but yes I do have it set for JT4A, I am currently on 80m decoding fine with JT65A.

Looked at the Rate in & out in setup/options & are both set for 1, the rate shown at the bottom left is usually very close to 1.0003. I would say that is OK.

I will try again tomorrow.

Thanks again.

may be egg-sucking-lecture, but you have got JT4A set haven't you?.  Not B...G.

Andy,

You wrote :-

Watch & check your sampling rate calibration. for this mode.

Is that displayed in the box at the bottom left, if so then it is always within the recommended figures. I read in the user guide to watch those figures for stability & I have never seen it go outside the range specified in the manual.

There is an "Enable Diagnostics" in the setup menu but no description in the use guide (WSJT6), it must be an addition in 7.03 but not documented. Is that of any help to me?

Station calling about 503.670 kHz but no decode. Not sure why :-((

LF,

I am currently transmitting a WSJT JT4A test signal on 503.600 kHz at each even minute, the ERP is estimated at 200 mW.

In a while I will change the message to a CQ call & watch for any JT4A replies.
