[Updates of this firmware version]
1: RIT/TXIT functions / added.
2: Reverse function in repeater operation / bettered.
3: Beep sounds at turn-off the power / added.
4: CTCSS tone of Auto-repeater & memory / bettered (give priority to the
tone in memory, not in VFO while auto-repeater is ON)
5: Welcome-screen setting / bettered.
6: New scan mode added = turns on the LCD light when scan stops. Very
convenient operating G7 in the dark.
7: Firmware update operation: accepts the command only when the
battery-icon shows "full".
8: Minor bugs fixed.
Previous firmware: Bettered receiver performance around 320MHz range.
I have not tested this on the birds. But the local repeater using the
same antenna. Not a very advanced test. Receiving the repeater before
upgrade, flashing the firmware and test again from the same spot.
Anyhow the original antenna is not good on VHF but i think the UHF/SHF
is better. Using the original antenna for the TH-D7 on the radio you
gain better signal on the Alinco. So i have replaced the antenna for a
SC951 SureCom for V/U and SHF and now it's better on VHF too.
On the birds i probably want to use another antenna but the SC951 should
work ok and better than the original on V/UHF. For SHF i have nothing to
compare them on.
I really like the dual-memorybank(splitband) so they are perfect for the
birds. But i have not done any QSOs on the birds using this radio. But
with the dual VFO control it's probably bnetter than the TH-D7 as you
can adjust for dopler on RX on the Alinco. (The TH-D7 can only adjust
the band you are TXing on)
So then i just have to try AO51 ;o) i just wanted to say that they have
done something with the filters and i think they have adjusted more than
just the 320MHz range even if they don't say so.
They are responding relatively fast on e-mail if you have any questions
or suggestions for new functions or to change something into the better.
