Re: U3S power out on 630M

 

Thanks Hans.?? I had read that mod information but it seemed to only show the power out after the mod.? I wanted to make sure I didn't have an issue with the lpf possibly before doing the mod.

Great little radio and very impressed.? WSPR spots last night in Europe on 80 meters.? I was thinking of possibly ordering another one to dedicate to 2200m, 630m, and 160m.

For those that have used their U3S on 630M, what was your power out into a dummy load with only one BS170 and 5V to the PA?? I did see a modification that changes a capacitor value to increase the power output but I was hoping to get some data before any mods were done.

My U3S is capable of transmitting on 20, 30, 40, 80, 160, and 630 meters and works very well with no build issues other than low power on 630M.

Thanks
