P3/SVGA Macro and USB

David Box-2
I am in the process of getting a Genovation KeyPad working with the
P3/SVGA but also want to have the keyboard available as I like to run
RTTY and CW without the computer.  So I have a few questions:

1) Has anyone found a USB switch that would allow selectable use of a
keyboard or the genovation with the P3/SVGA.  There are multiple USB
switches for sharing peripherals between computers but I have found
nothing that serves as manual USB hub equivalent.  The P3 cannot work
with a USB hub so need something like the old RS232 switch box.  Right
now I just plug and unplug but laziness is the mother of invention so
looking for a simpler approach.

2) What methods are people using to load macros into the P3/SVGA.  The
only approach I am a aware of is through manual keyboard entry which is
error prone.  I believe that once the macros are stored in the P3/SVGA
that they are saved with the configuration but there is no ability to
edit the 50 macro locations.  Back on 6/11/2018 Paul had stated "...The
next BETA release of P3/SVGA firmware will include the ability to
export/import macros from/to the SVGA just like the PX3." but I am
unable to find any BETA releases since that time.   The P3 Utility is
limited to only 16 Macros so that doesn't handle the problem. The
capability that the PX3 has for exporting/importing/editing of macros
would be extremely helpful.

3) Using the the P3 MENU -> SVGA menu->  SVGA Usav you can save the SVGA
state via USB stick which creates a file "SVGASET.sav" file name.  I am
able to open this file with a Notepad++ and see that it does contain
macro information but I cannot find any information on the file format. 
File contains a lot of NUL characters and appears to have 3 sections. 
Has anyone decoded this format and knows how to safely edit?  The PX3
Programmers Manual shows the format for the PX3 files and it appears
that the macro section may be the same but looking for more definitive
information.

Re: P3/SVGA Macro and USB

Hi Dave,

Using the setup described at:

https://www.nk7z.net/adding-external-keypad-k3/

I have been unable to swap to a KBD from the Genovation.  I direct swap
fails, so prior to purchasing a switch, do a manual replace to insure it
works for you...

Macro Loading is by hand, using that God awful editor that lives in the P3.

I was thinking of writing an editor for the file the P3 generates, but
as it is Elecraft hardware, (and I, not having the specs for it), have
decided to not do that, so I don't break the hardware inadvertently.

I seem to remember a Macro Editor for the P3 being promised as well, but
for the life of me, I can't find the reference to it now...

You are correct, it is a PITA to enter 48 macros by hand...

But, hacing the radio macro set available at a sngle button press has
been a Godsend for pile up operations...  I have a macro spread sheet
there, that has a "Split + 5", macro, so when I hear VP8PJ, I SPOT it,
then hit the "SPLIT + 5" button, that moves the DX station to the left
side of the P3, opens the bandwidth of the P3 up to 6 KHz., and makes
VFO B the transmit VFO, leaving the DX station on the left side.  Makes
it a snap to find a hole and work them.  Using that method, iot took me
three button presses, and a few tuning adjustments to get them on 40...

I can tell you from experience, that using the Genovation, and it's 48
macro launch buttons makes using the radio a breeze.  I had occasion to
use a friends K3, without a Genovation, and it felt crippling...

Please let me know what you find for Macro Editors, or external
keyboards, I'll add it to the web page on the Genovation...

73, and thanks,
Dave (NK7Z)
