Re: [Elecraft] K3s audio problem

Sid, Why aren't you using the sound card in the K3S? Then your JT65 and PSK software talks to the K3S sound card through the USB cable. Then you do not need external sound cards or connections to LINE IN, LINE OUT or the front panel MIC jack. I operate AFSK RTTY and this is how I have MTTY, N1MM

Re: [Elecraft] K3s audio problem

Sid, In that case, you would set the MIC SEL menu to FP.L as you have it, and feed the soundcard output to the mic input. Note that this has nothing to do with your headset that you use for SSB. Use DATA A mode rather than SSB because that data submode sets compression to 1-1 and the TX EQ

I can't comment on that specific generator. I do have some experience with inverter generators. In one case, a Honda 1 kW used at FD, there was no detectable noise from the inverter. But a friend has a 3.5 kW Honda that he uses when RV'ing and it is terribly noisy. The ARRL ran some tests

Re: [Elecraft] K3 and inverter generators

Ramon, While it should do the job for producing AC for your power supply, I wonder about the "Inverter" part of it. That tells me that the native generator produces DC and is then run through an inverter to give AC output. Some inverters do produce RF noise, so I would want to try it out
