That power supply should be fine, is the reported 13.5V measured at the radio? GL with finding the KX3 output problem. John KK9A Kyle Krieg wrote: Astron SS-30M-AP What Astron power supply are you using? John KK9A Bert ve3nr wrote: It seems your power supply doesn't have the capacity

That sounds right, so the PS is working OK. According to the manual you need only 3.5 - 7 W drive for 100W output. Have you checked that 3dB attenuator, Pin, RF Drive, is in the OUT/AUTO position? Bert VE3NR On 2022-10-18 14:57, Kyle Krieg wrote: I don't have anything that would draw

891 needs a 23Amp minimum supply per the manual. 20 amps wont do it. -73- FrankKG9H kg9hfr...@gmail.com > On Oct 18, 2022, at 1:57 PM, Kyle Krieg wrote: > > I don't have anything that would draw 20A's, but I do have an FT-891 and I > think the power supply is good. > > FT-891 puts out

I don't have anything that would draw 20A's, but I do have an FT-891 and I think the power supply is good. FT-891 puts out 98W on full key down with PS reading around 15.3A output in the same setup as the KX3/KXPA100. Kyle __ Elecraft

Kyle, Do you have another radio or load so you can draw around 20 amps from the PS and determine that it's working OK? Bert VE3NR On 2022-10-18 10:55, Kyle Krieg wrote: PS is showing 12.7A at 13.9V output on full keydown. That is with the KX3 powered from the back of the KXPA100. Kyle
