[Elecraft] Elecraft PA via Generator Power?
One of the first tests I did after the dual-fuel conversion of my Honda gen was with the KPA-500. Worked flawlessly, and I highly recommend the conversion.

Yes, BUT For the 2KW Honda, how long do you want it to run??? SEE "long Run Kits" https://www.amazon.com/Bergs-System-HND1-2000IS-Single-Tank/dp/B07K385YGX/ref=sr_1_2?dchild=1=honda+generator+extended+run+kit=1618178399=8-2 You can also find the parts to make the kit and modify a "cheap" plastic gas can... 73, Steve WB3LGC On 4/11/21 7:46 AM, Dave wrote: I asked the same question on eHam yesterday.

Re: [Elecraft] Elecraft PA via Generator Power?
I have the big Yamaha inverter generator, an EF6300i. it makes fantastic electricity and runs any electronic devices with no problems. I do turn off economy mode if I am only running radio gear. The inverters are much better than open frame 3600 rpm " box store" units. They have a much better waveform. When I first got the genset, we had a power failure and I was running the house on the inverter. For grins, I fired up my HB 4CX1000A 10 meter amplifier with 1100 watts out, and made some CW and SSB contacts. Then I went into the house and asked the XYL if she noticed any problems with the electricity such as flickering lights etc. She saw no problems at all. The only problem with inverters is RFI. You have to suppress the output with ferrites. Dave K1WHS On 4/11/2021 7:46 AM, Dave wrote: I asked the same question on eHam yesterday.

[Elecraft] Elecraft PA via Generator Power?
Anybody know, or have experience using an Elecraft PA (a 500 watt in my case) with a generator supplying AC power (a Honda 2 KW in my case)? I’ve not done it yet. Wanted to check to see if anyone else has prior experience before I end up blowing the final, or some such. The Honda flavor I have is the inverter styleand they have been known to put out a crappy “signal” at 60 Hz on occasion, not to mention fluctuations due to differing load at different moments.
