JTDX is recommended2020年10月25日 20時24分36秒

Hello everyone.

With the 6m band in the northern hemisphere now in the off-season, I'm sure many of you are playing on the HF band.

What software do you use to operate FT8?
Statistically, I think the answer is WSJT-X > JTDX > MSHV, in that order.

Then how does the decoding capability compare? In the QSO of FT8, if you can't decode it, you won't get a QSO.

My environment is as follows.

IC-7600 V-dipole
CPU i9-9900K 32GB Memory

This is just a result of my environment, but the decoding performance was JTDX > WSJT-X > MSHV. JTDX is multi-threaded, and if you're using a high-performance CPU , I definitely recommend JTDX.

I'm sure you can understand that the 6m band has a lot of QSOs on very weak signals, and the difference in decoding capability has a big impact on the performance. Whether or not your QSO partner uses the JTDX, which has a high decoding capability, will have a big impact on whether or not a QSO is possible.

In fact, most 6m DXers in Japan use JTDX. Although many Japanese HF FT8 aficionados use the WSJT-X, the use of the JTDX among 6m aficionados is much higher than that.

I wonder if anyone around you has compared the WSJT-X with the JTDX. I think that there may or may not be a difference between WSJT-X and JTDX depending on the capability of the computer you use, but if the CPU has more power, there will be a big difference and JTDX will win.

I hope that the number of JTDX users will increase among 6m enthusiasts as well.
