[Elecraft] K3 - 3.06 and KRX3

[Igor Sokolov]

I finally got enough courage to upgrade to ver 3.06 and try "true 
independence" with KRX3. Here are some questions that I hope someone can 
help me with:
1) I do not have KXV3 installed. I have one tribander connected to ANT1. 
Having tuned main RX on 20 using ANT1 I am trying to set SUB RX on 15m using 
the same antenna. Firmware does not allow that. It says USE AUX. Is that how 
it meant to be? I thought there is internal splitter (which I can use 
successfully when using both RX on the same band) and therefore I should be 
able to use the same antenna when MAIN and SUB are on the different bands.
It now looks like one more relay would be proper in antenna switching 
arrangement. I wish I could choose any mix of ant/rx from the front panel. 
Is an external antenna selector the only option for such a flexibility so 
far? Or I just miss something?
2) When in the contest I change bands by entering frequency into logger's 
call window. Now I have some local noise on 160m and therefore have to use 
NB there. For some reasons NB ON setting is not memorized. That means every 
time I come back to 160m from any other band I have to switch NB ON again. 
Is that a bug or is that done on purpose?
3) Having read all the previous messages on the subject I still do not have 
clear picture of how to make SUB RX drive both earphones without resorting 
to use of command tester. Is that the work in progress?
4) AF knob has recently fallen apart. I have discussed that with several 
other users here in Russia and found that it is pretty common case. It would 
be good to have substitute knobs made of some better  plastic or aluminum. 
Is there a source somewhere in the US?

Still I like this radio so much that I have recently ordered another one. As 
far as I know it is already on the way here.
K3 and EXPERT 1K-FA solid state automatic amplifier with the set of 
Spiderbeam antennas and light telescopic mast is ideal DXpedition setup for 
me.
