I was doing some research regarding the K3 and HRD. I am a long-time HRD user on my current rig and would prefer to continue, should I purchase the K3.

The AGC problem: If you are using HRD only for rig control, is there a problem?

The K3 is probably overkill for my rag chew operations on 160/75/40 - but, it is on my short list. After fifty years on the air, I decided it was time to get something that is really good. The other contender is the Flex3000.

Thanks,

OK, you did well. But, you said you included the sub-rec. I would
suggest that you plan your filters carefully, as the sub-rec is
mounted over top of the main rec filters. If you need to change your
filters, you will have to remove the sub-rec to do it. Also, you
will have to remove the sub-rec to change filters in it as well.
This is a PITA.

I don't know what a "PITA" is, but this is something I should have considered!
I downloaded and read the assembly manual a couple of times (but not the subreceiver manual) but this didn't occur to me and my mind just skipped over the way the filters are mounted.
I ordered a 400 hz filter for the main receiver, but it didn't dawn on me that I would need/prefer to have the same filter in the subreceiver (I did ask for matched 2.7's). I also did not catch on that the subreceiver uses a different receive-only antenna (I think), which is a problem in my very small lot. What I think I will do is put up some type of dipole--as long as feasible--and use that as receive and send on the buddypole, that I also bought, until I can come up with a better manner. Here in Lincoln in the apartment I will just throw a wire out the window to make sure the subreceiver works OK and have some fun until we go back.
My budget is now in the red because of splurging on the subreceiver so I will probably get the filter later.

Doing a better job of considering the filter setup better than I did is good advice for anyone buying the K3, with or without the additional receiver. However, as someone mentioned, after building the radio I think I will know it well enough that changing filters won't be a problem, but it WILL take time away from operating! (hi, hi)

The mat and the wrist strap arrived from amazon yesterday and I saw that each just had an alligator clip-plug combination on a single wire and no way to tie them together. So, I went to the web and found references on using them with computers (I always just used the "keep one hand on the power supply case" method!) and that is exactly what all of them said.
I am noting this here just for those that are considering, as I was, the purchase of a new product. When I get home I will figure a way to tie everything into the station ground, but for now I think that just clipping the mat and strap to the chassis I am assembling should work well.
Any counter opinions from those more experienced with these newer static-sensitive circuits?
