Diversity mode preamp

W8JI
Is there a way to lock the preamp and attenuator functions in the diversity
mode so I only have to hit the preamp to kill both RX preamps or add
attenuation to both channels without hitting the B set?


Thanks!

Double tap A>B sends all A settings to B but that may not be what you want.  You could also set up MACROs for ATT and PRE which would do what you want but the operator would have to know which buttons (e.g. PF1 and PF2) you assign this to.

Not. That writes A to B.

I have them used up for filter/BW selections.

I'm trying to get the radios set up for the 160 contests, and some of this
stuff is killing me.

The loud click over the air when the radio goes back to RX and the preamps
are the major impediments I'm trying to solve.

Why wouldn't the preamps/ attenuators track both channels when in diversity
on external antennas?? Everything should track, except balance. :-)

I guess I can build external attenuators/preamps, but I would rather use the
internal.

Not. That writes A to B.
Single Tap A>B writes frequency only to B...Double Tap A>B writes everything including PRE/ATT settings.  

Regarding ganging ATT/PRE in Diversity, I like it the way it is.  I often switch from an RX antenna on Main to my TX antenna.  I then set ATT on Main only so Gain stays balanced with the other RX antenna on Sub (normally no ATT).

Exactly, which is a real "operating mess" when someone only wants to turn
the preamp on or off. This is unsutable for contest work, and barely useful
for normal split operation.

I can't think of many cases where, when in diversity on two RX antennas,
changes in the preamps or attenuators (and all other controls) would not
track. I can understand not tracking amplifier changes when a TX antenna is
used with an RX antenna, but not with similar systems on both receivers.

I think this is a needed firmware change. When the receivers are in
diversity and not on the TX antenna, attenuators or preamps should track.
It would much more often be the case, with a good system, that they should
track.

Well, it is a disappointing deal breaker for me. I either have to build a
box with two preamps and two attenuators in it for two K3's, or use a
different system.

I cannot see a reason why, when the two external RX ports are selected, the
receiver functions would not fully track in diversity. The case I can think
of where they should not track is when the TX antenna is used for an RX
channel. In that case there should a fixed attenuation offset to equalize
the TX down to the RX antenna level, or the station builder should have
amplified the RX up to the level of the TX antenna.

A good system would have the noise floor of the two channels equalized, and
any gain changes for condition changes would then track.

I don't know why anyone would want to write the RX frequency into the TX,
just so they can turn a preamp off or on when noise levels change or a
strong station gets close. That might fly in single frequency operation, or
casual operation, but not in a contest or during a pile up!

I'd like to find a work around, other than building two boxes with two
preamps and two attenuators in each one. Rewriting the TX frequency every
time the preamp or attenuator is changed is unacceptable.

If you need a macro, but have run out of macro storage, you might consider
developing a small piece of software that does the switching for you with a
keystroke on the keyboard or a mouse click.

I don't care much for macros (not that they don't serve a good purpose), so I
wrote a program to replace macros for rig control.

For contest use, with a variety of ops who are already not fond of radios
with multiple function buttons, and for use with a variety of logging
programs where most keys already do something, it pretty much needs to be a
button on the radio or an external box (last resort) I build.

The objective is to make things more intuitive and easier to remember and
less bothersome. :-)

That's funny - those same words are exactly my reason for wanting to
keep the preamp/attenuator settings independent, and having them *not*
track.

As we so often see, there are valid reasons why different users need
their K3 to behave in completely opposite ways, so any firmware change
would need to be an option in the config menu.

The real problem is not the independence, but the fact there is no practical
way to change the sub receiver preamp without resetting VFO B to whatever is
in VFO A.

That totally ruins the ability to quickly throw a pad in on the second
receiver during contacts when using split. or when retaining a frequency in
VFO B.

It is a terrible system when, just to change a preamp or pad, the operator
is forced to accept unwanted changes to different settings.

I use B SET to adjust preamp and other settings when using diversity.
Double tapping to get the same settings is not the way to go for me.
However to get both receivers to the same settings it is the best way to go.
Perhaps I misunderstand your comment.

Right. It is all too cumbersome for a contest change, although the push and
hold A/B for B set at least does not rewrite the VFO.

The problem is contest use, and complicated by guest ops. I want guests to
like what they use, and not go away disliking something. It doesn't matter
how great a non-contesting solution is, or a TX antenna solution. That isn't
helpful to my situation, where it has to be easy and fast and only change
one thing.  \


:-)

Anyway, this is enough for now. It looks like there is no solution at the
moment and no need to drag this out further.

Thanks,
Tom

I rarely do contests, so I am not able to understand the "all too
cumbersome" comment.  I find for my dx chasing, diversity, etc., the current
set up is what I need.  I don't disagree that some other menu settings might
work better for what you want.

I would think that could work for those who need them...  there are bunch
already written and shared in the reflector that may address this.

This may not apply to this thread...  I don't know that all users have the
time or are PC literate enough even when it comes to doing macros.  That
does for some require above low average PC knowledge.  I don't write this to

amount of hand holding to understand the process and then the required

Because:

1.) the operator is busy making two or three QSO's per minute, barely
keeping up with logging keystrokes

2.) unfamiliar with the radio already, and the buttons are close together
and serve multiple functions

3.) has to remember what to do while distracted by a dozen other things

4.) will get totally hosed if something goes wrong by a mistake

 It is competition use under pressure where the operator barely keeps up,
which is different from other use.

I understand the goals of this are entirely different than a small front
panel and people having time to think about what to do, and mistakes are not
devastating.

I don't think there is a solution here for now, because I think the problem
is too specific to contesting with diversity on multiple receiving antennas.

Thanks for all the responses. I'm fully satisfied and appreciate all the
input.

Re: Diversity mode preamp

Phil Hystad-3
So, what the K3 really needs then is a contest oriented application on a computer.  Maybe something rich like PowerSDR but works with the K3 in a manner where contesting features (logging and contest log management) along with sophisticated macro control from a visual controls perspective.

Indeed, now that I think about it, this would be a great application if it were designed to be configurable per each contester.  Arrangements of controls on the screen, sophisticated macro control via custom U/I, and other nifty features.

Thus, instead of sitting in front of the K3 with its small format presentation and the overload commands on the buttons, the computer would be much more useful if all K3 functions were available.

Of course, it should be written on a Mac, or maybe an iPad.

Re: Diversity mode preamp

David Gilbert

There are very few things important during a contest that N1MM does not
already do, and the ones that it does not do would be very clumsy on a
screen even if the K3 allowed it.

And I own an iPad, but I cannot think of a less efficient interface for
doing a serious contest.
