1) On 2 very different computers the TX switching of the COM Port Latches the TX on permanently, TX STOP puts it back into RX mode but only closing the software unlatches the COM port.

2) Audio out levels are very high, higher than any other Ham software, I will need an audio attenuator between line out and rig.

Subject: Re: LF: JT9: A New Digital Mode for MF and LF

This is exciting news being a 2-way mode, especially as it is 9-FSK, so doesn't need a linear PA. With bandwidths as small as 0.4Hz for the long version, no-one will be complaining about how much bandwidth all this digital stuff takes. Unlike OPERA, the software will be well documented and open source.

There is a danger that, with too many digital modes now available, the activity may be spread too thinly, a point Mal raised some time back I believe Somehow though I suspect JT9 will rapidly become the de-facto digital mode on 472kHz and 136kHz.

I hope that one of the internet databases - PSK Reporter I guess, or perhaps an equivalent to WSPRnet - will be able to display JT9 activity as this was one of the great bonuses with WSPR beaconing.

I may give it a go on 500kHz next week.

He released the mode 2 days ago and a first update yesterday.

Now it really gets complex which mode to choose. WSPR, Opera, JT9...
But as a digital mode for LF i gues JT9-30 is the most promising at all.
