[KX3] Simple LiPo Power Source

The power supply described here,
http://chuckprice.wordpress.com/2014/04/06/kx3-portable-lipo-power-solution/,
is indeed very elegant and offers lots of protection to a LiPo battery

However, if you want a more straightforward lightweight power solution
I've had good experiences so far with a Zippy 30C Series 4200 4 cell
battery. Max voltage is 13.2V and for SOTA activations this has more
that enough voltage stability to maintain full power over a couple of
hours SSB operation. I have two Zippys in case I'm doing a two day
weekend activation.

I carry the Zippy in an old sock (washed!) and this in turn goes in an
old biscuit box that contains my KX3 (wrapped in bubble wrap), my Yamaha
CM-500 headset and other small accessories. This then goes in my
backpack and I've found this is more than enough protection for both the
battery and KX3. The power lead between the KX3 and battery can be
fused for short circuit protection. I use a Turnigy Accucell 6 for
external charging.

[KX3] PX3

Anyone who was at Dayton or anyone lucky enough to have seen one... can
you say what do the buttons and the rotary control on the PX3 do? Are
they 1:1 with respect to the P3?

Hi Dom,

The PX3's controls perform virtually the same functions as the P3's. I've been using the PX3 a lot lately, and it really feels like a P3, including the ability to set up hot-keys into menu functions.

Re: [KX3] PX3

I played with one a bit at SeaPac - aside from the small screen size, it
looked/acted just like my P3, and, it apparently has the P3SVGA built-in (at
least that's my understanding)

Re: [KX3] PX3

Clay,

The screen size on the PX3 is the same as the P3 - it uses the same part
(I got that info from the designer).
It does "look" smaller at first glance, but I believe that is because of
the smaller enclosure frame around it.

73,
Don W3FPR

The PX3 uses exactly the same LCD as the P3. Same size. No wonder it looked/acted like your P3 :)

The P3SVGA is a planned option, but yes, it would be built-in. No prediction on when that will be available.

Re: [KX3] PX3

Perhaps the confusion is based on the fact that the USB connector, which
is part of the SVGA option in the P3, is standard in the PX3.

The input to the P3 is an IF signal, 8.215 MHz in the case of the K3.
The input to the PX3 is an I/Q baseband signal so that it can work with
the KX3.

Within the limitations imposed by that, we tried to make the
functionality of the PX3 as identical to the P3 as possible.

Hm, K3 to LP-PAN (or Softrock) to PX3? IIRC, at least one person has cut
down a P3 to be physically smaller for travel.

Yeah!

That's actually what "got" me - I saw the USB connector and asked "Oh, is
the SVGA INCLUDED in the PX3?" and was told "Yes".

So, to clarify - "out of the box standard", the PX3 has a USB input, but
does NOT have an SVGA interface. Is that correct?

Thanks; and sorry for the confusion!

Correct. SVGA is a future internal option. (The connector will actually be mini-HDMI, which can be used with an adapter to get to SVGA.)

Then, the mini-HDMI will be HDMI protocol for video? If so, thank you Elecraft! If you could create an HDMI P3 option that would be great too -- I would definitely buy it -- no SVGA exists in this house.

It's actually there. I'm not sure what functionality will be supported
in firmware at first shipment.

Correction: the current plan is for the PX3's video output to be compatible with the P3's SVGA option, which means analog video, but with a miniature video connector that is TBD. It may be possible for us to do digital video in the future, but there is no current plan to support this.

Sorry for the confusion.
