[600MRG] LF: SlowJT9 update

[N1BUG]

Hi Rik, all,

I will install the latest today, let it run overnight and send you
the requested information tomorrow.

I am sorry I dropped the ball on testing of your program over the
last few nights. I had some life challenges outside radio and had
just enough time to squeeze in some grabber changes to catch DK7FC's
LF activity. Best to jump on DFCW activity when one can, as
(unfortunately!) there is very little of it these days.

I should be back to more normal starting today, and will return to
testing SlowJT9.

Everyone:
After tonight's receiving test to log decoding time info I will be
looking for anyone willing to try some JT9-5 transmissions on MF or
LF. Also, if anyone within daytime range on either band has the
ability to adjust TX power in 1 dB steps I am very interested in
doing some controlled tests stepping between modes and reducing
power to check the minimum decode level of JT9-2, -2, and -5.

Rik:
SlowJT9 has now been running continuously for 3 days (or is it 4 ?)
without any problem.

73,
Paul N1BUG
