Fan on all the time
For the power it puts out this thing is small. The fan runs constantly rather than having a heat sensor to turn it on,a little noisy in the background. The output power switches are backwards, high is lo and vice versa,might have to fix that. Now to see how long it lasts.Update: sent it back. SWR too high and unit unuseable as a mobile. Tried 2 different antennas. SWR over 7.5. Oh well,I tried.
