P3 wish list

I found checking and adjusting the K3 output on the P3 a useful function. Would it be difficult to make it a front panel function w/o the need to reach in the back and remove the RS232 cable?

Re: P3 wish list

That's an easy fix. But I have so many boxes on my desktop and it would seem more natural to me to be incorporated into the P3. Doesn't seem like it would be a major project.

Re: P3 wish list

I assume Alan monitors the reflector :-). Hope he is sufficiently interested.

Agreed, I concur with you. I don't need any more boxes on my desk either, especially when a button on the Menu could turn off the RS-232 'mute' control.. seems like a pretty easy thing to do to me. Just thought that I would give you a work around for the time being.
Be sure to send your ideas to Alan.. he's the only one that can program it into the P3

Re: P3 wish list

I would like to be able to 'switch' such a feature On/Off without any
external 'box'

As I am operating portable all the time there is a need for me to check this
daily.

YMMV

Re: P3 wish list

Unless you change microphones or operators, transmit audio equalization
should be pretty much a "set and forget" type calibration.

I'm a little nervous about making this an "official" feature, because
the signal level is not well-controlled. It depends on stray leakage
through a balanced mixer and "blow-by" past a couple of PIN diode
switches. If the mixer in a particular K3 happens to be very well
balanced or the PIN diodes have extra-low capacitance, there may not be
enough signal level to adjust the equalizer properly. It also depends
on frequency band and transmit power level.

There may be a better way to do this. It's on my list of things to look
at as soon as I get time.

Re: P3 wish list

Alan,
Thank you for considering it. I do think it may have value beyond equalization, eg. signal width, etc. I can understand your reluctance as you describe the pitfalls. I certainly wouldn't feel bad about waiting for a better implementation. Possibly after the effects of your turkey dinner wears off it will be replaced with a new energy to update:-). Kudos for the very nice job you all have done so far.
I didn't jump right in on this one because I didn't think it of sufficient value for me but I am very pleasantly surprised at the result. An excellent station accessory.

73 and Happy Thanksgiving to all,
Howard..K2HK

Re: P3 wish list

In reply to this post by Alan Bloom-2

Hi Alan:

I certainly understand your reasons for nervousness here. However,
I would like to express how much this "unofficial" feature has been
helpful to me in setting TX equalizers for three different mic settings
(macro driven) and two mics (front and rear). And I often return and
tinker with these settings for optimization. In my P3 the "feature" works
well, but right now it is clumsy to use, to say the least.

Here is what I have to do: Open Config Menu: RS232 which will read
38000. Attach a dummy load (or tune to an empty spot in the band).
Turn on Peak hold, then right away turn RS232 speed to 4800 (this is
equivalent to removing the cable), talk into the mic, and then tap
freeze to look at the cumulative audio spectrum! Set to a narrow span
(I use 4khz) one gets a lot of good detailed data this way, but is it
a bit of a fiddle! If you want to do it again, start over.

Alan, I know there are interesting options coming down the line with
some additional hardware required (what else is the "sensor" opening
at the back for?) But in the meantime, the "unofficial" feature is very
useful indeed!

Thanks so much for the fine panadapter. It has proven itself to be more
useful than I thought it would be.

Regards & 73

Re: P3 wish list

Alan,

I too find it useful BUT I am happy to wait for a 'better' solution.

I understand 'in the future' there maybe be a hardware option to add this
and perhaps 'other' features from previous emails so for now I wait and
watch.

I was never sure if the P3 would be a 'keeper' for me but it is here now and
after playing with it I can't see how I got along without it in the
beginning...:-)

Sometimes Elecraft 'force' us to buy stuff..:-(

Just too many good engineers with plenty of time on their hands eh?

ROTFL
