Subject: [Moon-net] Future JT65 plans ?
Dear VHF EME Friends,
Some of our UHF friends have been chiding us for not including unknown signal
reports in most of our JT65 QSOs on 6 and 2 meters. True, we almost always
exchange grid locators, which is not generally done in UHF CW QSOs; but it can
be argued that the grid locators may not be truly unknown, any more than the
content of an "OOO" report is unknown. (What *is* unknown to the other station,
of course, is whether you have copied both calls yet, or not. Sending "OOO" or
"RO" signifies that you have.)
Of course, I know that the customs of VHF EME are slightly
different from those of UHF EME. I have tried to make JT65 compatible with
conventions used in both communities, as much as possible. Let me draw your
attention to the fact that JT65 supports the transmission and reception of
numerical signal reports in dB, as in the following QSO:
1. CQ VK7MO QE37
2.
VK7MO K1JT FN20
3. K1JT VK7MO -24
4.
VK7MO K1JT R-22
5. RRR
6.
73
In WSJT v 4.9.5, messages 3 and 4 will be decoded by the fully general Reed
Solomon decoder. They will not, however, benefit from the extra sensitivity of
what I have called the "deep search" decoder. If there is any enthusiasm for
having this capability, I will add it to the deep search decoder in a subsequent
program release.
Your input on this and any other aspect of JT65 will be much appreciated --
either off-list or, if you think your comments will be of general interest, here
on Moon-Net.
Comments and suggestions from UHF EME stations are especially welcome. Since
I am not QRV for EME on 432 and above, I do not always know what improvements
are most needed there.
-- 73, Joe, K1JT
