Decided I should give the JT65 mode a whirl after hearing how much success Scott W9JSB was having.

As I had earlier been on the 160m SSB Every Night Net, I thought I would see if there was any JT65 on 160m.

What a surprise as at 1.838 there is a raft of stations – at least that is what it sounded like “by ear.”

Downloading the JT65 software was easy – setting up things to work with PowerSDR and the Flex-5000A was a bit roundabout but doable.

The result was QSOs from the start!

Here is a screen shot of the software running (you can click to see a larger version):

All told I only made Eight JT65 160m QSOs – they take several minutes each – here is the calls and reports:

WA3WZR -17
N4UPX -08
WB2HTO -3
K4JJQ -08
VE9DX -03
N6KMR -10
K0IDT -04
W5GW -12

Went right back and added another ten QSOs:

AB8KZ
W9OL
KB3MOW
KJ4IZW
KA1QW
WT9S
KD8EZS
N4UFO
N4WD
WB4FSD

JT65 is a rather unusual mode in that it is about making the contact, and just about anything else is “chatter” and generally technically a difficultly.

Here is a descriptive and history of the mode: http://en.wikipedia.org/wiki/WSJT_(Amateur_radio_software)

The Project’s Homepage is at: http://sourceforge.net/projects/jt65-hf/

Flex had an article on configuration that was based on an older versions, but helped: http://kc.flex-radio.com/KnowledgebaseArticle50362.aspx

Definitely an interesting mode and I am sure I will play around with it a bit.

Hope to meet you on 160m JT65 sometime soon!
