JT65-HF

In an attempt to brush up on my JT65 message techniques, I shall try a few QSOs today with JT65-HF (basically JT65A). I've used this mode before successfully. Then it will be back to 2m and JT65B to see if I can make that work.

JT65 is a very weak signal mode for 2-way communications, unlike WSPR which is essentially a 1-way  beaconing mode but WSPR will work with even weaker signal levels.

UPDATE 1645z: Plenty of EU and USA stations heard on JT65-HF around 28.076MHz,  but none raised for a QSO.  Moved to 28.078MHz for JT9-1 but band was dropping out.  Will try on HF again tomorrow AM.

    Try JT9, almost the same as WSPR but a qso mode. 73 Paul

    I agree with Paul furthermore the new wsjt-x is very convinient to use and no stick to JT65_HF anymore
