JT65A on HF

Having seen the article on how to do this in the latest edition of Practical Wireless, I have installed the software and taken a listen/look. Main issue seems to be that the AGC in the FT817 is fierce and with close-by PSK31 signals it kills the gain of weak JT65A signals nearby. Anyway, it looks a useful mode. For HF use, download the HF tailored version at http://jt65-hf.sourceforge.net/. Not yet had a 2-way QSO but will soon when I've got the hang of this.

Have you tried turing the AGC off (and backing off the RF gain if the Rx overloads)?

Hi. I´ve FT817 and no problems with JT65. I copied signals -28 dB and multiple stations. You can see a pic of screen in my blog ea1gfy.blogspot.com
I´ll hoped to see in my waterfall.

GB3VHF on 2mtrs sends JT65B as well as cw, so if you have 2mtrs, try decoding it.
