So, is this a good problem statement?
Negative.
This may be hard to grasp if you have never used an
IC756p 775dsp, or OMNI VI+.
I have an IC-706MKII. (Speaking of bad user interfaces ...)
The object is to have single press access to a desired
band, on the last freq and mode you used - without
ever needing to specifically perform a "save"
operation of that frequency and mode in the past.
But that already happens when I return to a band. I guess I don't see
the huge advantage of have a separate button to do this when the
standard band-changing button already does that. OK, I have to press
my band changing button multiple times to get from 6M to 160M but that
is not a likely scenario. Most of the time the band I want to get to
is only one or two button-presses away.
The rig is smart enough to know anytime that you leave
a band using memory recall or FREQ ENT, to store the
last band's freq, mode, and filter settings for single
button recall later.
Well, the K2 already does that. I am assuming that the K3 does too.
I'm just not seeing an advantage yet.
And isn't it more likely that people are going to grab the VFO knob
and twist? If you do that how is the radio going to know to save the
freq? See, you still need a button-press to say "remember".
The "stacking" art of the idea happens when the rig is
smart enough to save (for example) the last 3 places
you were on 10 meters, without you ever having to
press a button.
How does it know what the "last" three places were? When I change
bands? That seems just silly. The radio is not telepathic and can't
know that I want a particular frequency? If it only happens when I
leave a band, well, that seems silly as well and now we are back to
the "frequency of interest" stack I suggested. Oh yeah, when I enter
another frequency with the keypad. Yeah, I do that all the time ...
NOT. I tune across the band with the VFO looking for interesting
signals.
Look, you want to know what comes naturally to people? Sit a new ham
in front of the radio. I guarantee they are going to grab the VFO knob
to change frequencies, not key in a new one on the keypad.
(Caveat -- the K3 may already have this, I don't know. If so, I
apologize for wasting everyone's time.)
For example, the first press of the 10 meter button
would call up 28.010 CW 500hz, the second press,
28.400 usb, and the third press, 29.600 FM with PL and
negative offset - if these were the last three spots
on 10 meters where you were operating.
So I spin the VFO dial, hear a CQ, and reply. Is that when the radio
knows a frequency is "of interest"? Does keying the rig mean "save
this"? Do I have to enter a new frequency or change bands? Seems
awkward. Seems like, "remember this," or, "remember this in memory
1," (I understand that the K3 does this already) makes more sense to me.
All of this is a user-interface issue. Frankly, the user interface on
most radios that have microcontrollers sucks.
You never have to press "save", you have an automatic
"bread crumb" trail of all the most recent places
you've been
I must be dense. No matter how it works I still need to do *something*
to indicate that a frequency is of interest. Just pausing on a
frequency is not enough. I may have gotten a phone call. I have to
*DO* something to make the radio know to save that frequency. And if I
have to do something, it may as well be to tell the radio explicitly
that I want this frequency.
I am somewhat sensitive to this issue right now. I have 12 new hams in
my classroom (10 tech and two upgrade to general). They are all
chomping at the bit to get on the air. I am telling the kids that to
get on a repeater all they need to do is set the repeater output
frequency, the offset, and the PL tone into the radio to get in. One
5th grade boy conned his folks into getting him a new Yaesu VX-3R HT.
OH MY GOD what an awful radio. I spent a good 5 minutes trying to
fathom that abortion of a user interface and then had to punt to the
7th grader (just upgraded to general -- good kid) who had more time
than I did. (I still had to work with the other kids.) After both of
them spending 15 minutes heads-down over the manual they figured out
how to program repeaters and save them to memory. An hour later I
asked the boy to show me what the sequence was to program a repeater
into his radio. The response? "Uh ... (furrowed brow) ... (poke-poke-
poke) ... (deer-in-headlights-look) ... (run for the manual) ... uh,
could you help me again?" Yeah right. Good job Yaesu.
From now on my recommendations on radios are going to hinge on the
rationality of the UI. It doesn't matter how good the radio is if the
operator can't figure out how to use it. And if you can't use it
without the manual, how are you going to use it in the field?
(BTW after all this I tossed them an old IC-2AT I use as a hidden
transmitter for our T-hunts. The response? "But this is so easy! How
come the other radios aren't this easy?" At least Elecraft has active
hams working on the design of their radios so there is SOME hope for
us. :-)
So, give me a simple, obvious UI. I can dispense with most features.
And while I don't think you can beat the UI on the Collins KWM2, the
K2 is pretty usable. Certainly the kids and I can manage to get that
radio on the air and on the proper mode to make contacts, without ever
having to consult the manual. Set the band, set the frequency, set the
mode, set the filter, set the keyer speed, and start. We even go from
band to band and the last frequency/mode/filter for that band pops up.
No huhu.
Well, there is one nit -- who came up with the brilliant idea that AGC
OFF is not on the AGC button? Another friend has a K2 and didn't even
know there was an 'AGC Off' function! I had to explain that it was
function-shift-filter-power-PTT-meta-control-alt-delete-something to
turn the AGC off and to go look it up in the manual. Hello! Fast,
slow, Off, Fast, Slow, Off. It isn't rocket science.
(Sorry. Sometimes I get carried away.)
