Comments:
Late start on 7 MHz. Activity there lasted till
about 0725Z. Next 14 MHz had good signals. Even
worked Stan AH6KO, but unlucky with Max VE6RST
and a few others more Westward in the States.
Last minutes on 21 MHz nil.
Yesterday I started to test my newly acquired
Exide EV-640 50 Ah LiFePO4 with the IC-7300.
For RX-only it is supposed to last 56 hours
after a full charge. For TX it turned out better
than expected. In a S/P session it probably delivers
6% of its energy and with active CQ maximally 10%.
In this session with a lot of active CQ, the SOC
dropped from 75% to 67%. Voltage from 13.3 volts
down to 13.2 V at the end of the session. Closer
to its empty state the IC-7300 RF- output will
decline due to lower battery voltage. I guess,
a pack of 6S LTO (Lithium-Titanium-Oxide) is more
appropriate for nominally 13.8 volts rigs, and will
stay functional down to -40C (-40F), unlike LiFePO4.
