I have a request for a K2 feature. I have a K2 with KPA100 and KAT100 in separate EC2. Currently, if the KAT100 is installed, the KAT2 just switches to through mode (CALP), fixed to ant1.
I recently bought an amp and find that neither the amp, nor a typical antenna, is cleanly 50 ohms and hence there's work for the tuner. If I enable the amp, I need to autotune to the input impedance of the amp, if I leave it offline, I need to tune to the impedance of the antenna. This requires two different tuner settings. I note that the KPA100 has a separate pin to drive the PA key line which means that, through software, the K2 can 'know' whether or not it puts the amp in-line: if the software doesn't key the key line, you're running barefoot. Instead of the current two antenna settings, I believe more choices are possible: A. KPA100/KAT100, ANT1, key PA line This is the normal case and puts the PA in-line. B. KPA100/KAT100, ANT1, don't key PA line This leaves the PA in through mode and makes the thing run barefoot. Note that the K2 needs separate KAT100 settings for A and B as one is obviously driving different things C. KPA100/KAT100, ANT2 I've found that using two antennas sometimes helps, I've ran with a quad and a W3DZZ D. KAT2 ANT2, no KPA100/KAT100 For transverters and the like I note that the various SWR bridges have outputs that can be three-stated, just like currently happens. I really, really want more flexability in my antenna settings. Also note that all four settings would need separate, to-be-memorized tuner settings. Oh, and when you'd hack on the antenna selector code, perhaps the code can be improved: sometimes the KAT2 is stuck in CALP mode after attaching a KPA100 at a previous session. It would be nice if it would switch back to regular AUTO mode if the KPA100 isn't there. What do others think?
