Redneck engineering manpack
(lemmy.radio)
An ice fishing box to house my ic-7000, an atu, a battery pack. Very crude but solid rack made of pine board I had laying around. This is cobbling of the best sort.
How much power does such a radio need? At what voltage (or just I and U)?
Ever since USB-C powerbanks with up to 20 V from PD are a thing, I use them for as much as possible.
Voltage is generally standardised to 13.8 V (don't ask me why).
I don't know what exact radio that is, but it looks like it can probably transmit at 50 W.
13.8v is the charging voltage of lead acid batteries. So it stuck.
That's a ic-7000 and it does 100w out on hf.
