My KRX3 kit arrived this weekend, and built it yesterday. Installing it took quite a few hours, but instructions were clear and it installed without any issues. Draping small coax links were annoying as they have to be plugged in to the module, then find a residence that doesn't prevent the module from dropping down and plugging in. I did find two small errata items to report, but nothing that would prevent following directions so to speak.
The sub receiver worked right off. there are firmware items that one must take care of before it is going to respond, but instructions are clear. Think through the filters you will want as taking it apart to install new filters in either the sub receiver or the main receiver is more work than you will prefer to do. However, I am seeing posts that suggest many owners still think that need a roofing filter as narrow as the IF DSP which I doubt very much. I suspect some folks are filling up their slots when it is very much unnecessary. the difference between a 500 and a 200 cycle roofing filter at a spacing of 2 khz is nil, at a spacing of 1 khz is almost undetectable. At a spacing of 500 hz, only a signal that is 40 db over nine is effected, and even that one, if the signal has clicks which it probably does, the narrow roofing filter isn't going to make any difference. The diversity is fine. all other behaviors that I had time and circumstance to explore was good, in fact, very good. I liked how I could switch to the sub and indepdently control all parameters using the same knobs and buttons. I did find that when linked if I tuned the frequency change seemed to stutter. this may have something to do with filters not being matched. I also noticed that when linked if I used the auto-tune feature, the main receiver auto-tuned but the sub receiver did not. also there is the statement that you need firmware version 2.11 etc, and for me at least, that firmware was no where to be found. I wound up downloading and using beta firmware 2.15. I am sure many other ordered sub receivers are going to be landing and come up very soon. 73, Fred - kt5x K2 # 0700 K3 # 0144 _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
