Hi Andy,

Had a quick look at the pdf, I think I partially understand.

Does it mean that the other JT4 modes are different in the character format which can be used (transmitted)??

I will modify the message to 13 characters in the mean time.

In its plain text mode which you have used, it can cope with just 13 characters.   See http://www.g4jnt.com/Coding/JT4_Coding_Process.pdf   and the WSJT documantation

Hi Ko,

Thanks for the decode, not bad a -10 db at one point.

There must be a character limit on the Tx text box (Tx1) I have used as there is more than you have decoded. I will try placing the same text into the Tx6 box & see if it sends more or all.

Hi All,

For a while tonight I am transmitting a beacon on 503.600 kHz.

The mode of operation is WSJT JT4A, transmitting on even minutes.

Only using 15 watts RF & ERP 100 mW.

If anyone would like to try & decode the message, post the results on LF & I will confirm correct or not as the case may be.

Sorry, no prizes :-((
