[Elecraft] KPA500 delay in amplification

Guys, I am using a K3 with a KPA500 and KAT500. Everything was working well until I tried sat down at the station this morning. When I key up, the KPA500 doesn't amplify right away. I am running into a dummy load with the KAT500 in bypass. For the first 4-5 seconds, the amplifier is only

Re: [Elecraft] [K3] RX Gain Calibration

Thanks Stan. I ordered a XG3 yesterday and I hope to have it here this week. I wasn't expecting such a huge discrepancy between the KX3 and K3, and it really surprised me. If I figure out the secret sauce, I'll definitely let you know. I am curious, with did you put the KX3 and K3 on the XG3

Re: [Elecraft] [K3] RX Gain Calibration

Hi Don, I agree 100%! The S-Meter isn't as big of a concern to me as the fact that the noise floor seems to be so much more prevalent on the K3 than the KX3. I do understand that the more sensitive receiver will dip deeper into the noise floor and you will hear more of it. If I always have

[Elecraft] [K3] RX Gain Calibration

All, I put together a K3 kit about 6 weeks ago. Wow, that was an amazing project. Many thanks to Elecraft for making that option available. The problem I am having is that on 180/80/75/40 and sometimes 20, the noise floor is about S7-9. It is about the same on both my antennas (OCF dipole and

Re: [Elecraft] [K3] RX Gain Calibration

- if there is still a substantial increase, try turning on the attenuator. You are not going to be able to copy signals below the noise level, so you don't need the added gain - it just makes everything (including the noise) sound louder. 73, Don W3FPR On 3/18/2013 8:24 AM, Travis Brown wrote: All
