hmmm, well I'm hearing a lot of opinion expressed. First off, how many of you have acctually built ckts for10-GHz+? (show of hands) And of you who did, how many worked the first time as designed without "tinkering"? Snow-flaking is a well known method of "tweaking" the circuit to get it to

Re: [Elecraft] K3 Preamp 2

Barry, Not disagreeing. I bought my K3, SN4043, in 2010. It has an internal preamp (push PRE) which gives about 10-dB gain (I think). A few years went by and Elecraft announced the PR6 external "add-on" preamp to improve 10m and 6m receiver performance. They kind of admitted the bare K3

I don't know why people say stuff like that.  Just because some variables become more important at RF than they did at lower frequencies doesn't turn design into art or magic. Dave AB7E On 4/8/2018 11:45 AM, Kevin Cozens wrote: On 2018-04-08 3:42 PM, mike.ab...@gmail.com wrote: It
