Hello Bill,
... So I am curious how long the battery generally
lasts before going dead.
The time is dependent from your operating style, the installed option, the
output power and from the style you wound the transformer for the internal
K2 PA. I have not count the hours between charging periods. But its longer
than I want to operate without a break. ;o)
The following is based of equal periods for transmitting and receiving,
because i.e. I send my QTH info and receive the same info from the other
station.
1 hour QSOs = 30 minutes RX + 30 minutes TX
If you use CW you don't transmit the whole 30 minutes, because there are
spaces between the dits and dahs. The real ratio is about 1:1 while TX.
So the new formula is
1 hour QSOs = 45 minutes RX + 15 minutes TX
Now back to the K2. My K2 need 0.28 A while RX and 1.84 A while TX. The
current is dependet from the installed options and more in your K2. Measure
it with the internal meter!
45 minutes RX = 0.75 hours x 0.28 A = 0,21 A
15 minutes TX = 0.25 hours x 1.84 A = 0,46 A
--------------------------------------------
1 hour QSO = 0.67 A
The internal battery contained 2.2 Ah so you can operate 2.2 Ah / 0.67 A =
3.28 h (= 3 hours 17 minutes).
These period is valid only for hardcore QSOers. If you receive longer than
you transmit, so the result will be greater.
